The shiny gleam of freshly cut metal is hypnotic and mesmerizing. Appreciate your open honest sharing of experience, your helping a ton of people being like that.
As an ex military guy and a cnc machinist I will say that this is very common in the industry. Ineffective communication from the top down. Our motto in the Army was, "Training is not SOMETHING we do, it's WHAT we do." Systematist and standardize your training, in skills and leadership and you'll never worry about finding qualified applicants. You will create your own.
Dang I would’ve never guessed from where you are today, that you have been in a position like that. I guess we all start from somewhere. Thank you for staying humble. Shout out to your quality and the standard of perfection you stand by. You are an inspiration! BOOM!
Mr. Titan, I applaud your videos. I graduated from college 4 years ago with my Associates degree in precision machining and tooling. I work as the lone Machinist at a private company that manufactures its parts in house for the equipment they make. So I work hand in hand with our engineer whom knows very little about running and operating our Haas VM3. I have job security thanks to watching your videos and the videos from Haas. In the past year, I was able to take a particular part with a run time of 3 1/2 hours and I tweaked the program to have a new cycle time of 33 minutes. I know very little about CADS like Mastercam. But thankfully I understand how to read NC code and watching your videos, I can have our Haas run at maximum power with carbide tooling machining our aluminum parts. I would like to know more about Mastercam so that way I can assist our engineer and take a large chunk of the work load off his plate. Keep up the fantastic work! Thank you.
Good jump in productivity! 👍 Keep that up and you'll be running the shop soon. Just don't get cocky, stay hunble and treat everyone as equals. God Bless, best of luck and productivity to you!
You say common sense! I say that this is one of the most important things in any of your videos. I once said to a former employer, when I was still pretty fresh in his shop, "If there isn't a specific procedure in place, and something goes wrong, it's noone's fault. Until somebody gets hurt, then it's your fault!" I later got fired for doing 20 parts with a 7mm hole instead of 6mm. I had picked up the drill from the tool rack where the drills were stored in drawers labelled by dimension. In the midst of the discussion, it came up that the owner had put it there but that I should have had a calliper with me and measured it (it was an HSS jobber drill that had been ground down to a stub drill basically). I then proceeded to point out that this was a failure of procedure and that we were both at fault and effectively, since we could both have avoided this we should learn and agree on a procedure instead of fighting over it. I mentioned the outcome above.
Good Machinist aren't born, they're made. I've been CNC machining for 10 and still have a lot to learn. A good Machinist should take his or her job very serious, and be professional. All machinist should be a good inspector aswell, because if you don't know how to check that part, maybe you shouldn't be making it. At the end of the day we don't make parts, we make art, and its something you should be proud of.
Damn, you story reminded me of the goof up that I did. After living in California for 3 years after getting out the Navy I returned to my home in New York State and got a job at a cutlery. On my first day of work I was put on a stamping machine that was supposed to stamp Case xx on knife blanks. The machine was set up by my supervisor and he showed me how it worked and walked away and left me alone to do the work. I was thinking the same way that I was going to show that I could pump these out quick. When he came back to check on my work I had done a stack of them but unfortunately the stamp was not on straight and I got blamed even though he had set up the machine. I only lasted working there for a month before the union went on strike and I decided that this wasn't a job I was cut out to do so I rejoined the Navy. Spent 25 years there and never went back to New York to live.
Your part is your business card.! It represents you!! I've been sent home twice, years ago. 1 for $14,000 part, other for $19,000 part. Both times told to go home, get my head out my ass and don't return till I was called. 4 work days and 7 work days later I was called back, both times. Haven't scrapped a big piece since
I had a similar situation on a job years ago when NASA's JPL program needed 4 parts pronto. I was an operator running someones else's program that was half assed. Being up against the gun and higher ups constantly wondering when I was going to be done because they were sending it up in space in a month. Being stressed and not focused also not slowing my roll and asking to fix and adjust the program. I ended up with delayed shipment and very disappointed in myself. My lesson learned was to slow down and COMMUNICATE and get it right the first time. Not let the higher ups get to you letting you loose focus. Great video I can relate to!!!
When i first started machining my trainer had me start out inspecting his parts and reading his prints while he explained the datums and GD&T. He always said if you understand how to check the part you can make the part.
In had a similar experience. Learned the hard way the difference between climb and conventional cutting on a mill. They were stainless aircraft parts with a slot milled in. I thought that I developed a quick pattern and checked every other part. Every part that I checked was within tolerance but the other half were bad. I wasn’t milling the same direction each time. I climb cut one part , never returned the machine to start position just chucked next part and back tracked, ( conventional cut ). Those were too big but never checked them. Didn’t know it mattered. Even got first article and random inspections.
I don't own a CNC, I don't run a CNC, I've maybe been in a machine shop a handful of times, but I am a CAD guy and the lessons Titan is speaking about transcend all industries and all trades. I come for the chips but stay for the life lessons. Thanks for being humble enough to share your failures so that we may never have to have them. BOOOOM
I had a similar situation with an employee who happened to be my wife's cousin. I was originally hired as a temp to fix about 5,000 4 inch cubes of brass that was already put thru a few hours each of NC work.This was back when our newest machines were Bridgeport BOSS 6 tape machines. They were drilled for a 10-24 roll form tap and somehow tapped with a cutting tap. Because my background is Swiss style tool making I was hired for my skills in hand work , but as they became comfortable with my work they pulled me into the main shop more and more and started doing setups on the NC mills. Since I needed to move around the shop to use machines that might be needed during the day , I worked on the less populated night shift.The shift was a foreman who did the setups , edited and even typed jobs into the tape maker and operators with little to no experiance. It got to the point of me putting in as many hours as his " deputy foreman " as I was fixing those parts. About the time "Jack " was teaching me how to make tapes my wife " asked " my to get her cousin a job.The first night I new this was bad. Jack put me in charge of him and 2 other new guys.The other 2 guys had some skills so 1 went on a manual 2nd op lathe and the other on a BOSS 5 Bridgeport. The cousin , having no skills I put deburring some 16 ga steel parts. I went to do some of my own work and went to check on the new guys about a 1/2 hour later.The 1st 2 guys GREAT , the cousin --no . I told him to just break the wire edge with as small a chanfer as possible. His chamfers met , you could shave with those parts. I did another one to show him and told him to set it aside as a master and look at it to make sure he had it right. 10min later I go back and he's making razors again. I had to move him away from hand work so I had a real simple job on an NC mill.Short program with 1 tool change ( we had manual tool change with power draw bars ) and a programed stop for a clamp move. 1ST piece he changed the tool on the clamp stop ( this tool had 2 inches more TLO than the 1st tool) I put him on a broom while I cleaned up the crash and edited the program so the tool was too close to the table to take out. 2nd piece he came to the clamp stop , couldn't get the tool out so he just re started the machine without moving the clamp , the non-turning endmill was RT'ed into the clamp. I told him to punch out , his check would be mailed.
Hello again Titan. Man you gotta be one of the best story tellers ive ever seen. You could make sewing seem interesting the way you tell stories. Anyways just wanted to say Hello from Nakina Ont, Canada. Hope all is well and you can bet the farm ill be watching this channel and getting my friends to subscribe as well. Thanks for being so down to earth. The world needs more people like you. Sincerely Jason Ritch
Hey Titan, great video and story. I first started machining in a very small job shop/repair shop 2 years ago. over those 2 years I definitely made mistakes while manually machining and welding. broken taps, broken inserts, broken drills. but I gained a ton of experience! I'm currently 2 months into my new machining job that is ISO9001 and ISO13485. your videos inspired me alot to look for better work.
I can’t tell you how many parts I scrapped AR15 barrels But you live and your learn (only some of us do) I see everybody started out in a MFG shop Just buy a machine 🤖 and do it Your right inspect your part A lot of gauges Cut once measure to many Times 😂 Love your channel
oh man what a great story! it made me think of a time I worked in a 5-person job shop. My boss spent a TON of time programming and making fixtures, buying custom tools and everything for aluminum natural gas manifold blocks for car conversions. He finally got it to run perfect parts, but they took several hours a piece. The customer needed a bunch of these blocks, so he put me and another stoner kid on graveyard shift for just a couple of nights just feeding the machine. When I took a part out, I noticed the tap only cut like 3 threads and the hole was pretty deep, so I grabbed a tap and "finished it" (not knowing the purpose of the hole or having any print around). I did that to the few parts we made that whole night. In the morning, the other guy left and my boss got back. I was over doing something at the bandsaw when I heard my boss yell "DAMNIT DALTON!" and threw a lathe chuck wrench across the shop after seeing those tapped holes! I was so scared I never fessed up to it and he luckily he didn't confront the other guy either. Apparently there needed to be an O-ring in that hole to keep natural gas from leaking out.
Always tell someone when you make a mistake...don't try to slide it through............You will be respected more..... machinist no matter how good makes scrap.
Hey man did they make you a necklace out of those lol! I scrapped a part when I first started in this trade and my mentor put it in a chain and told me to wear it! Till this day it hangs on my Kennedy box! Love your channel I just came across it looking at a machine video
Ohhh you remind me of a near disaster I made when I was 15 years old back in 1963....I worked for an Electronics company in Sheffield UK that made Large Induction Heaters and Audiometers, strange combination... but I was given a job when I worked in there machine shop to drill 2 x 3/8 inch holes in Copper blocks measured about 6 inch x 4 inch by 1/2 inch thick there were about 50 ... they were taking for ever in this jig one at a time on a Meddings Drill press .. so I decided to do 2 at a time ... after they checked them half of them were out ... but my saving grace was they had to open holes up to 3/4inch so they put on a Milling machine.. luckily didnt loose my job...LOL
I did the exact same thing with my first job in a shop on a drill press making chamfers. Luckily for me, my depths were too shallow and there were only 30 or so parts. So the next day the inspector came over and told me what I did wrong, showed me how to do it the right way and I just hit them again and they were all set
I love how you put things into perspective , I have been saying own your mistakes for so long customers will respect it and trust you more thanks for your videos. Your awsome
I'm too young on machining parts. One day my boss told me to make a metric thread on a lathe [my first thread ever], also told me feeds and speeds and was looking meanwhile I was working. I asked: "Why we can't go faster? And he answer: "You could brake the insert. Space between chuck and torret is shorter, and the thread is larger. You can crash the machine". So I didn't hear his advice and..... Fortunately I only broke the insert, but I learned that he told me the right things cause he has the experience [25 years working on different shops]. I think as workers, we need to pay attention to the instructions and worksheets. Everything is there.
18 years old and I had a person watch over me whenever I did anything. He came over from welding and explained how I messed a part. It was one part but I felt so bad, regardless of how expensive or inexpensive it was.
QC is honestly right up there. Especially for a business owner/annoying overseer. "Hey, don't forget to remember and make sure there's no mistakes. Focus." Lmao
As a CNC machinist for over 26 years ,,I noticed a recurring trend happening in the comment's .. People telling stories of scrapping parts and even though it was their mistake they still find a way to blame procedure.. As Machinist ultimately the part we are making is in our hands.. So you can blame procedure all you like but at the end of the day the mistake is your fault... So if you make a mistake and scrap out parts.. If you're blaming anyone but yourself,,, you are not learning...
I agree with this to an extent. If you have a job that makes good parts, but there are variables beyond the control of the operator you can't blame them for bad parts being made. Right now at my shop we are making parts that some times get pinched or crushed by the parts catcher. There is absolutely nothing the operator can do about it. Once the part catcher starts it's return there is no stopping it. All I can do is make sure they know how to identify damaged parts and make sure they don't go forward through the process. We lose maybe 2 parts out of 80 a shift. Some days we don't lose any. Personally I can't tell you how many times I've had to go to my supervisor and say "I fucked up". I remember working on a VERY late job, made out of aluminum. While testing the threads on the mating parts I seized the threads together scrapping both parts. I had to go to my boss and explain. He understood that we had to test the fit of the parts. It was a crazy thread like 90mm x.5 pitch.
I can relate to you in many ways. I am currently working to build my knowledge in cnc programming. Everytime i see your videos it inspires me even more to keep pursuing cnc programming. I think i am currently enrolled in your academy, but i don't know how to use it. Thank you for inspiring other, and sharing your story. I would really like to conversate with you in regard to some issues i have with cnc programming.
Hey, another Important vid. Sharing the experience and your pain (should) teach an important lesson to anyone willing to learn. When I was learning CNC the first time, back in 1995(ha!), my teacher sent me to see if I could help a new CNC set up at a long established engineering company that was having a lot of problems. I volunteered my time for a month for free to see if I could help. The two men working those machines were only learning but hadn't got the knack of the CAD CAM package and we're trying to write very basic G code programs directly at the controller. They also, it became obvious, hadn't been QAing their parts. When I started to check the storeroom of parts against the drawings they up and quit that day, like right the moment they realised what I was doing. Long story short, the owner of the business and I went through the entire 3 months of work in that room and it was scrapped. Every critical dimension was out. ID's were big, OD's were small, burrs on every edge, poor surface finish..... etc. Lessons learned: Learn to measure! Check sizes routinely. Note tool wear with an eye to tool change timing. Learn the CAD CAM package, it is vastly superior to manual programming. Write notes about tooling, work holding jigs, tool change intervals and any other hints that help INTO the program for any jobs that are likely to be done again or repeditivly. Don't hide your mistakes. Never assume. Learn All the time... TOUGH LESSONS
I know I'm super late to the game here but I work in aerospace manufacturing and am only recently getting the chance to learn CNC programming. I have actually had a similar situation where I destroyed 10k in parts due to badly machined parts before they even got to me on my line. I didn't know how to fix it on the line and just drilled them out and they all had to be thrown out. It was a lesson and I'll keep in mind how I screwed up and learned how to fix things before I do that again
Quality! Absolutely aware of the challenges faced with quality particularly with using low cost 3D printing, a good example is headed your way via Shanie! I have to say that making errors is usually one our greatest forms of true education in life, and without mistakes, we may never know if we could have done, or can do, better. In terms of inspection, Titan could you do a separate video on how to do a correct part inspection report, using say one of the Building Blocks parts, and highlighting potential traps and pitfalls when measuring components, as well as the minimum types of inspection tools a student through to CNC expert should be using. Thanks as always!
Another great video. Really like that you own the error & use it constructively, even though they should have trained you better. Learning from our mistakes is the best way in any industry. Thanks & keep up the good work, you are literally helping people who may feel hopeless change their lives.
My biggest mistake.. we machine 3 to 5 ton drums, which are chained down on vee blocks with 3/8 chain, and chain binders you see on semi trucks. The last step is to machine the bulkhead bores which is with a 26.375" bore bar. I had bumped the B axis lever while in jog, and that miniscule amt of time it was bumped, kicked the drum off of B270 degrees. So the bore bar came up to the part, spinning at 110 rpm. With it slightly rotated, the rougher was beating the hell out of the bulkhead so hard that it was picking up the drum off the vee blocks, WHILE chained down! BANG BANG BANG BANG until the spindle was shut down. The drive dogs off the 6" quill, or W (which was extended 18") were sheared off. The 50 taper of the bore bar was WELDED inside the spindle, and wouldnt release. I felt lower than terrible. News like that travels fast across the entire plant. They had to hire guys to come in and re-grind the spindle. Lessons learned, 1. To shut the spindle down, DONT hit feedhold. The spindle keeps spinning. Feedhold shouldn't be a red colored button, its misleading. It just stops the feed. Hit reset or E-stop. Practice it! I've seen people not hit e-stop because they were "afraid". Know where all of your estops are around the machine, and think about what you would do in an emergency. 2. Just above the G0G90G54.1P1X0Y0 start line, add these codes.. G0G91G28Z0W0 (older machines, some of em can crash if they dont start from a Z0 reference point) and G0G90B270. Had these last 2 codes been in the control, while in memory, the machine would have gone back to B270.
Wow!! I have always liked your videos because of quality content, but this video is where I am at. I have downloaded Fusion 360, but made the mistake of selecting the 30 day trial version. I checked the Titans of CNC Academy Forum for the "way out" and get the education version. I am also checking your list of 240 videos to see if there is a video for setting up the Fusion 360 workspace for Lesson M1! I'm impressed! You have a video for every step of the job! It's a lot to learn, but I am eager to get started! I am specifically looking for the principles that will carry me through every part I make beyond what the academy has to offer. I was fortunate to have at least one person who could explain machining to me. Every question I had I brought it to him and he took the time to teach me. He is retired and dearly missed.
Thank you!! I just received a "Welcome to Fusion 360" email with a link to a video series "to learn foundational concepts of Fusion 360". I don't have internet at home. My fingers are crossed that I can take Fusion 360 with me on my laptop wherever I go. The interconnection of resources to create tutorials brought to one place through videos, documents, software, and other media can be overwhelming at times. I'm a visual person that is building a map in my head of everywhere Titans of CNC: Academy can be found. HA! 3500 affiliates is too big of a map for me!
I've had 3 scrap parts in the last 3 years and gotten written up for 2 of them. I felt absolutely horrible about all of them. With almost 20yrs experience all were stupid mistakes that I should have caught, but got complacent.
I work in a fab shop, we drill these cast aluminum bowls. The company purchased us a gang drill bbn to drill the 2 different sized holes. We only use that drill gang for that part, or so I thought. Well, I checked the drill bit in the first drill press head and it checked out. I didnt check the second...10,000 parts later I completed my work only to find that someone switched the second bit out..should have checked but I didnt know any better, why would it be wrong right? Well that was 2 years ago (still making those parts fo to this day). Eneded up staying after hours redrilling them on my own time! Valuable lesson..ALWAYS CHECK, titan will understand the feeling when I found out they were all wrong..
Started in deburring at the age of 13, was giving a $400 casting and told to deburr the holes. All I knew about was countersinking. So, 10 min later when I had a countersink about 1/4 inch in diameter, I asked if that was deep enough. I still have that wide eyed looked of my supervisor seared into my brain, 22 years later. So, like you Titan, first part I ever touched was scrap. Good vlog. Check us out @ www.fwmachining.com
That was a great video man keep them coming, I have just been moved up to supervisor at my shop and the stuff you put out in these vlogs are so helpful!!! Thanks man BOOM!!!!
Had a similar thing Titan, i had a job to cut bars, i taped 10 together to save time and it worked, but i had to give it to an apprentice to carry on as was too busy, long story short.. All undersize, i got a warning, 3k in material gone Lesson learned.. Never again Its just life lessons dude
Whos the editor of this video? You should give them a raise, love the lighting effects during the comments 'murdered'. You should have the screen shake whenever Titan says BOOM!!
Great story. It does leave me wondering if they fired you or just sucked it up as their mistake (which it 75%+ was). You weren't the only one learning a lesson there. My opinion is the only real path to mastery is to acknowledge your mistakes and learn from them. Never blame shift, that just poisons relationships and you won't advance like you should. People respond to a stand-up worker who takes responsibility.
6 months later I would become their head programmer and a year later, the shop foreman. 4 yrs later when I decided to move my family away from the city, Kevin offered to buy me a house if I stayed... Instead he bought me. Kennedy tool box and gave it to me on my last day since I was using his in our shop.
I work were a single part cost 5,000$ pure titanium, and guess what? So far no scrap. Takes 10 hours to cut. I dont move a inch from that 5axis machine.
I think we all went through this at the beginning, I had my share of oh snap moments learning in this trade. 😊 It's part of the learning process. They def were at fault for not presenting a good inspection process.
thanks for all the tips titan. i would also like to have my own cnc machining company in the future. thanks for all the tips you give in your videos. keep it up you are the best. greetings from the Netherlands.
Kinda left my 1st job because I didn't want to be responsible for plastic parts. When I was their, our department lost quality control inspections. So I had to inspect my own parts. Since it was plastic, it was difficult to get an accurate reading due to the fact plastic likes to flex around a lot and didn't know where to measure the part from the top of the cut or the bottom of the cut since it was cut at an angle.So I was spending an hour inspecting my own parts so I can avoid ruining whole set of parts. To add more salt to the wound, is that my lead didn't want me to spend more than 30minutes inspecting. Little did he know I was autistic. So I had one of my coworker helped me while getting trashed talked that I suck at inspecting. Just bear in mind this was my 1st year. So after a while I got the hang of it, putting it on 123 blocks, angle irons, etc. Then 1 day feeling rushed I accidentally mixed a z dimension on the blueprints and made my part .015in short by mixing the inside dimensional with the outside dimension ruining about 15 parts of plastic with the thermwood 5 axis routers. Moral of the story, take your time even if all your other coworkers are rushing you.
Titan, more great advice. Over the years I have made some good quality mistakes. Try thread milling and make a nogo gage go, and a go gage not go, and that was not just a couple threads either...That one pops in my head any time i am around thread mills. I have also been fortunate to have learned some excellent lessons from other peoples mistakes. I have an off topic question though, what has your CAD-CAM journey been like since you started your company (the different cad-cam packages up to Fusion 360 )?
T.G. THANK YOU I NEEDED TO SEE THIS.- I REPEAT -NEEDED TO SEE THIS. I AM THREE WEEKS IN AT NEW JOB AS CNC MACHINIST A TOP COMPANY. THE NEXT FEW WEEKS ARE CRITICAL AS THIS COMPANY HAS DECIDED TO INVEST IN ME AND MY EDUCATION . I SET OUT TO BE IN THIS VERY SPOT OVER A YEAR AGO NO MATTER WHAT LIFE THREW MY WAY. IT WAS A FIGHT I KNOW MANY INCLUDING YOURSELF UNDERSTAND. MORE IMPORTANTLY I KNOW THAT CARELESSNESS AND AVOIDABLE ERRORS COULD TAKE THE OPPORTUNITY. I WISH I COULD SHARE MY STORY WITH U SOMETIME BUT FOR NOW THANK YOU!! -ALEJANDRA (ALEX) CAZARES
How to read a bore gauge seems to be one thing I see people struggle with. Even inspectors. You can say, "do get this?" Yep, yep! And only to find out assembly cant get a bushing in because the bore is too small. Adding to the confusion is bore gauges measuring in micron, vs .01mm or even in inches. And then add to that, setting the bore gauge up off a ring gauge that is way off nominal, because the engineer didnt buy the right size ring gauge for the job. I found it helps to add a plus and minus on the bore gauge face so operators know if the bore is small or big. Some of our parts, I've programmed the probe to check the bore size, but with the length of the stylus we have to run, it's only good to .025mm (and that's with it pre probing a magnetic ring gauge set in a counter bore before it probes the part, to check/set the probes dia accuracy) Anyways, thanks for sharing!
I can only add that an entirely handiwork trade like fortepiano building lives and dies on the same premise of quality. The feeling in the motion of tools is the way to make them work without breaking your back - I am today forced to hand plane a very large soundboard to specific thicknesses, something my chaotic cnc machine & vacuum table have failed several times to produce. The trick is to make these machines functional, but it's much harder than normal woodwork, where the tool does tend to train your hands for you. The future beckons, still out of reach.
When I was about 15 years old I was in a similar situation all those parts you murdered was absolutely not your fault your employer / boss failed to give you proper training.
Guys, if you're subbed here and not signed up for the academy, please do so. even if you just like watching, there is no reason not to. It just gives you access to the material, files, etc. all for free. Worst case scenario you don't use it.
Our apprentice did something similar..didnt read the drawing properly and assumed the hole he was drilling in over 40 large blocks was in the centre but it was 5mm off centre...He looked so proud when he finished all the blocks 😂 As soon as we looked at one we went have you drilled that in the middle, yeah that's what it says on drawing, so we blew the drawing up so it was about 4ft across 😂 his face was priceless
Very fine and well explained. Am a convertional machinist and I would like to know about CNC machining. How can I learn practical CNC machining with TiTAN academy? I live in Zambia, Kitwe town, Africa.
Hey Titan! Could you please do a 4140 steel part demo? There is a lot of videos with a wide spectrum of feeds and speed of endmills. But can’t trust them. Your insight on how aggressive can we get with this steel would be great.
I discuss it in my earlier Vlogs and also have a view videos called Building a CNC Shop where I discuss it. Check out this channel and subscribe as I will speak more on it.
I have nothing to do with the cnc thematic but its still super interesting. You learn stuff even if u dont need it but hey if its free its free u know maybe there will be this 1 time u can use that learned knowledge in one of your projects.
Hi titan love your videos, I recently went through the same thing got an opportunity to work in a cnc shop, they got me to run parts one at time on the Cnc no measuring tools no paper work, after a while of running them the end mill didn't sound the same, when I spoke to the guy who do the programming he shrugged it off, after that they were all tapered, 3months on I still wasn't taught how to set up the machine and I left the company 😢
Not only quality, aestetics are extremely important. Parts can be nominal across the board and still look like trash. I know titans parts always look the best, I just thought it was worth mentioning. Customers always gonna go with the suppliers that provide the prettiest parts given that they're same price.
My question is how did you start? A man can dream till you're blue in the face but without money there is no start. So did you start with one small manual mill...or did someone else back you up with their wallet? What cad/cam software do you use?
I think it is important for designers and engineers, to indicate on prints, critical dimensions. Yes, when the print says this is 30 mil, and 5 mil accuracy on all dimensions tolerance somewhere in the corner, you sometimes do not comprehend and register, if this is really important or not. Often this is because it is critical, or sometimes it is because they are simply lazy. A lot of dimensions is not critical, but things like mating surfaces, pins, and fasteners position, and in this case chamfers, were critical. We often think about chamfers just as something cosmetic, and to help handling part. But in many situations the chamfers are the most important geometric feature of the part. And these should be marked as critical directly on the print, right next to a dimension of the chamfer.
The shiny gleam of freshly cut metal is hypnotic and mesmerizing. Appreciate your open honest sharing of experience, your helping a ton of people being like that.
As an ex military guy and a cnc machinist I will say that this is very common in the industry. Ineffective communication from the top down. Our motto in the Army was, "Training is not SOMETHING we do, it's WHAT we do." Systematist and standardize your training, in skills and leadership and you'll never worry about finding qualified applicants. You will create your own.
I’m all about quality. Been in the shop since 97’.
100% visual. Stay in tolerance. Make em look good.
The “Pile of Sadness”. Every shop has that heap of lessons-learned.
Dang I would’ve never guessed from where you are today, that you have been in a position like that. I guess we all start from somewhere. Thank you for staying humble. Shout out to your quality and the standard of perfection you stand by. You are an inspiration! BOOM!
Mr. Titan, I applaud your videos. I graduated from college 4 years ago with my Associates degree in precision machining and tooling. I work as the lone Machinist at a private company that manufactures its parts in house for the equipment they make. So I work hand in hand with our engineer whom knows very little about running and operating our Haas VM3. I have job security thanks to watching your videos and the videos from Haas. In the past year, I was able to take a particular part with a run time of 3 1/2 hours and I tweaked the program to have a new cycle time of 33 minutes. I know very little about CADS like Mastercam. But thankfully I understand how to read NC code and watching your videos, I can have our Haas run at maximum power with carbide tooling machining our aluminum parts. I would like to know more about Mastercam so that way I can assist our engineer and take a large chunk of the work load off his plate. Keep up the fantastic work! Thank you.
Jeez if you cut that much off the cycle time sounds like that programer needs be fired sad to say.
Good jump in productivity! 👍
Keep that up and you'll be running the shop soon.
Just don't get cocky, stay hunble and treat everyone as equals.
God Bless, best of luck and productivity to you!
You say common sense! I say that this is one of the most important things in any of your videos.
I once said to a former employer, when I was still pretty fresh in his shop, "If there isn't a specific procedure in place, and something goes wrong, it's noone's fault. Until somebody gets hurt, then it's your fault!"
I later got fired for doing 20 parts with a 7mm hole instead of 6mm. I had picked up the drill from the tool rack where the drills were stored in drawers labelled by dimension. In the midst of the discussion, it came up that the owner had put it there but that I should have had a calliper with me and measured it (it was an HSS jobber drill that had been ground down to a stub drill basically).
I then proceeded to point out that this was a failure of procedure and that we were both at fault and effectively, since we could both have avoided this we should learn and agree on a procedure instead of fighting over it. I mentioned the outcome above.
If you didn't measure the drill it is your fault...
No 1st article
Good Machinist aren't born, they're made. I've been CNC machining for 10 and still have a lot to learn. A good Machinist should take his or her job very serious, and be professional. All machinist should be a good inspector aswell, because if you don't know how to check that part, maybe you shouldn't be making it. At the end of the day we don't make parts, we make art, and its something you should be proud of.
Damn, you story reminded me of the goof up that I did. After living in California for 3 years after getting out the Navy I returned to my home in New York State and got a job at a cutlery. On my first day of work I was put on a stamping machine that was supposed to stamp Case xx on knife blanks. The machine was set up by my supervisor and he showed me how it worked and walked away and left me alone to do the work. I was thinking the same way that I was going to show that I could pump these out quick.
When he came back to check on my work I had done a stack of them but unfortunately the stamp was not on straight and I got blamed even though he had set up the machine. I only lasted working there for a month before the union went on strike and I decided that this wasn't a job I was cut out to do so I rejoined the Navy. Spent 25 years there and never went back to New York to live.
Your part is your business card.! It represents you!! I've been sent home twice, years ago. 1 for $14,000 part, other for $19,000 part. Both times told to go home, get my head out my ass and don't return till I was called. 4 work days and 7 work days later I was called back, both times. Haven't scrapped a big piece since
I had a similar situation on a job years ago when NASA's JPL program needed 4 parts pronto. I was an operator running someones else's program that was half assed. Being up against the gun and higher ups constantly wondering when I was going to be done because they were sending it up in space in a month. Being stressed and not focused also not slowing my roll and asking to fix and adjust the program. I ended up with delayed shipment and very disappointed in myself. My lesson learned was to slow down and COMMUNICATE and get it right the first time. Not let the higher ups get to you letting you loose focus.
Great video I can relate to!!!
When i first started machining my trainer had me start out inspecting his parts and reading his prints while he explained the datums and GD&T. He always said if you understand how to check the part you can make the part.
In had a similar experience. Learned the hard way the difference between climb and conventional cutting on a mill. They were stainless aircraft parts with a slot milled in. I thought that I developed a quick pattern and checked every other part. Every part that I checked was within tolerance but the other half were bad. I wasn’t milling the same direction each time. I climb cut one part , never returned the machine to start position just chucked next part and back tracked, ( conventional cut ). Those were too big but never checked them. Didn’t know it mattered. Even got first article and random inspections.
The most underrated channel ever.
I think so too! Why didn't I find this channel years ago?
I don't own a CNC, I don't run a CNC, I've maybe been in a machine shop a handful of times, but I am a CAD guy and the lessons Titan is speaking about transcend all industries and all trades. I come for the chips but stay for the life lessons. Thanks for being humble enough to share your failures so that we may never have to have them. BOOOOM
I had a similar situation with an employee who happened to be my wife's cousin. I was originally hired as a temp to fix about 5,000 4 inch cubes of brass that was already put thru a few hours each of NC work.This was back when our newest machines were Bridgeport BOSS 6 tape machines. They were drilled for a 10-24 roll form tap and somehow tapped with a cutting tap. Because my background is Swiss style tool making I was hired for my skills in hand work , but as they became comfortable with my work they pulled me into the main shop more and more and started doing setups on the NC mills. Since I needed to move around the shop to use machines that might be needed during the day , I worked on the less populated night shift.The shift was a foreman who did the setups , edited and even typed jobs into the tape maker and operators with little to no experiance. It got to the point of me putting in as many hours as his " deputy foreman " as I was fixing those parts. About the time "Jack " was teaching me how to make tapes my wife " asked " my to get her cousin a job.The first night I new this was bad. Jack put me in charge of him and 2 other new guys.The other 2 guys had some skills so 1 went on a manual 2nd op lathe and the other on a BOSS 5 Bridgeport. The cousin , having no skills I put deburring some 16 ga steel parts. I went to do some of my own work and went to check on the new guys about a 1/2 hour later.The 1st 2 guys GREAT , the cousin --no . I told him to just break the wire edge with as small a chanfer as possible. His chamfers met , you could shave with those parts. I did another one to show him and told him to set it aside as a master and look at it to make sure he had it right. 10min later I go back and he's making razors again. I had to move him away from hand work so I had a real simple job on an NC mill.Short program with 1 tool change ( we had manual tool change with power draw bars ) and a programed stop for a clamp move. 1ST piece he changed the tool on the clamp stop ( this tool had 2 inches more TLO than the 1st tool) I put him on a broom while I cleaned up the crash and edited the program so the tool was too close to the table to take out. 2nd piece he came to the clamp stop , couldn't get the tool out so he just re started the machine without moving the clamp , the non-turning endmill was RT'ed into the clamp. I told him to punch out , his check would be mailed.
Your a great human being. You are helping rise up humanity for the better.
I've been programming CMM's for almost 15 years. Working for a company now that is training me for CNC machining. Thanks for the great videos Titan!
I CNC hob gears. I am very similar to Titan in my passion for precision manufacturing. Thanks Titan.
Hello again Titan. Man you gotta be one of the best story tellers ive ever seen. You could make sewing seem interesting the way you tell stories. Anyways just wanted to say Hello from Nakina Ont, Canada. Hope all is well and you can bet the farm ill be watching this channel and getting my friends to subscribe as well.
Thanks for being so down to earth.
The world needs more people like you.
Sincerely Jason Ritch
Titans of sewing
Hey Titan, great video and story. I first started machining in a very small job shop/repair shop 2 years ago. over those 2 years I definitely made mistakes while manually machining and welding. broken taps, broken inserts, broken drills. but I gained a ton of experience! I'm currently 2 months into my new machining job that is ISO9001 and ISO13485. your videos inspired me alot to look for better work.
I can’t tell you how many parts I scrapped AR15 barrels
But you live and your learn (only some of us do)
I see everybody started out in a MFG shop
Just buy a machine 🤖 and do it
Your right inspect your part
A lot of gauges
Cut once measure to many Times 😂
Love your channel
oh man what a great story! it made me think of a time I worked in a 5-person job shop. My boss spent a TON of time programming and making fixtures, buying custom tools and everything for aluminum natural gas manifold blocks for car conversions. He finally got it to run perfect parts, but they took several hours a piece. The customer needed a bunch of these blocks, so he put me and another stoner kid on graveyard shift for just a couple of nights just feeding the machine. When I took a part out, I noticed the tap only cut like 3 threads and the hole was pretty deep, so I grabbed a tap and "finished it" (not knowing the purpose of the hole or having any print around). I did that to the few parts we made that whole night. In the morning, the other guy left and my boss got back. I was over doing something at the bandsaw when I heard my boss yell "DAMNIT DALTON!" and threw a lathe chuck wrench across the shop after seeing those tapped holes! I was so scared I never fessed up to it and he luckily he didn't confront the other guy either. Apparently there needed to be an O-ring in that hole to keep natural gas from leaking out.
Titan.. you killing it so hard.. keep it up and god bless you
I’ve gotten 2 years in the trade , and let me tell you finding your channel was a huge plus brother , keep up the awesome vids
How’s your career looking with a extra 2 years in the bag? Hope your doing good bro
Always tell someone when you make a mistake...don't try to slide it through............You will be respected more..... machinist no matter how good makes scrap.
I always say... you can almost always fix a mistake.
respect for telling that Titan, especially with the simplicity of it. from Ottawa Canada
Thanks
Hey man did they make you a necklace out of those lol! I scrapped a part when I first started in this trade and my mentor put it in a chain and told me to wear it! Till this day it hangs on my Kennedy box! Love your channel I just came across it looking at a machine video
Ohhh you remind me of a near disaster I made when I was 15 years old back in 1963....I worked for an Electronics company in Sheffield UK that made Large Induction Heaters and Audiometers, strange combination... but I was given a job when I worked in there machine shop to drill 2 x 3/8 inch holes in Copper blocks measured about 6 inch x 4 inch by 1/2 inch thick there were about 50 ... they were taking for ever in this jig one at a time on a Meddings Drill press .. so I decided to do 2 at a time ... after they checked them half of them were out ... but my saving grace was they had to open holes up to 3/4inch so they put on a Milling machine.. luckily didnt loose my job...LOL
I did the exact same thing with my first job in a shop on a drill press making chamfers. Luckily for me, my depths were too shallow and there were only 30 or so parts. So the next day the inspector came over and told me what I did wrong, showed me how to do it the right way and I just hit them again and they were all set
I am not into CNC but I do like the message you are pushing. Do good business and take pride in what you create. Great videos and keep it up sir.
I love how you put things into perspective , I have been saying own your mistakes for so long customers will respect it and trust you more thanks for your videos. Your awsome
A lot of people I know/work with need to see this video. I will be sending the link out. Thank you.
Thanks bro for not being fake keep up the good work good bless
One of the main things that I’ve learnt in the 35 years in my trade is learning from other people’s mistakes.
Videos like this always help keep me on that path and help keep me hungry to learn more. Thanks for sharing man
I'm too young on machining parts. One day my boss told me to make a metric thread on a lathe [my first thread ever], also told me feeds and speeds and was looking meanwhile I was working. I asked: "Why we can't go faster? And he answer: "You could brake the insert. Space between chuck and torret is shorter, and the thread is larger. You can crash the machine". So I didn't hear his advice and..... Fortunately I only broke the insert, but I learned that he told me the right things cause he has the experience [25 years working on different shops].
I think as workers, we need to pay attention to the instructions and worksheets. Everything is there.
18 years old and I had a person watch over me whenever I did anything. He came over from welding and explained how I messed a part. It was one part but I felt so bad, regardless of how expensive or inexpensive it was.
QC is honestly right up there. Especially for a business owner/annoying overseer. "Hey, don't forget to remember and make sure there's no mistakes. Focus." Lmao
As a CNC machinist for over 26 years ,,I noticed a recurring trend happening in the comment's ..
People telling stories of scrapping parts and even though it was their mistake they still find a way to blame procedure..
As Machinist ultimately the part we are making is in our hands..
So you can blame procedure all you like but at the end of the day the mistake is your fault...
So if you make a mistake and scrap out parts..
If you're blaming anyone but yourself,,, you are not learning...
I can totally respect you for what you said. I believe in being honest and telling your customers like it is so they never get screwed.
Root cause analysis.....?
I agree with this to an extent. If you have a job that makes good parts, but there are variables beyond the control of the operator you can't blame them for bad parts being made. Right now at my shop we are making parts that some times get pinched or crushed by the parts catcher. There is absolutely nothing the operator can do about it. Once the part catcher starts it's return there is no stopping it. All I can do is make sure they know how to identify damaged parts and make sure they don't go forward through the process. We lose maybe 2 parts out of 80 a shift. Some days we don't lose any.
Personally I can't tell you how many times I've had to go to my supervisor and say "I fucked up". I remember working on a VERY late job, made out of aluminum. While testing the threads on the mating parts I seized the threads together scrapping both parts. I had to go to my boss and explain. He understood that we had to test the fit of the parts. It was a crazy thread like 90mm x.5 pitch.
I can relate to you in many ways. I am currently working to build my knowledge in cnc programming. Everytime i see your videos it inspires me even more to keep pursuing cnc programming. I think i am currently enrolled in your academy, but i don't know how to use it. Thank you for inspiring other, and sharing your story. I would really like to conversate with you in regard to some issues i have with cnc programming.
Hey, another Important vid. Sharing the experience and your pain (should) teach an important lesson to anyone willing to learn.
When I was learning CNC the first time, back in 1995(ha!), my teacher sent me to see if I could help a new CNC set up at a long established engineering company that was having a lot of problems.
I volunteered my time for a month for free to see if I could help.
The two men working those machines were only learning but hadn't got the knack of the CAD CAM package and we're trying to write very basic G code programs directly at the controller.
They also, it became obvious, hadn't been QAing their parts.
When I started to check the storeroom of parts against the drawings they up and quit that day, like right the moment they realised what I was doing.
Long story short, the owner of the business and I went through the entire 3 months of work in that room and it was scrapped. Every critical dimension was out. ID's were big, OD's were small, burrs on every edge, poor surface finish..... etc.
Lessons learned: Learn to measure!
Check sizes routinely.
Note tool wear with an eye to tool change timing.
Learn the CAD CAM package, it is vastly superior to manual programming.
Write notes about tooling, work holding jigs, tool change intervals and any other hints that help INTO the program for any jobs that are likely to be done again or repeditivly.
Don't hide your mistakes.
Never assume.
Learn All the time...
TOUGH LESSONS
I know I'm super late to the game here but I work in aerospace manufacturing and am only recently getting the chance to learn CNC programming. I have actually had a similar situation where I destroyed 10k in parts due to badly machined parts before they even got to me on my line. I didn't know how to fix it on the line and just drilled them out and they all had to be thrown out. It was a lesson and I'll keep in mind how I screwed up and learned how to fix things before I do that again
Quality! Absolutely aware of the challenges faced with quality particularly with using low cost 3D printing, a good example is headed your way via Shanie! I have to say that making errors is usually one our greatest forms of true education in life, and without mistakes, we may never know if we could have done, or can do, better. In terms of inspection, Titan could you do a separate video on how to do a correct part inspection report, using say one of the Building Blocks parts, and highlighting potential traps and pitfalls when measuring components, as well as the minimum types of inspection tools a student through to CNC expert should be using. Thanks as always!
100% agree. If you look at any manufacture that has been around for decades they hold quality to thw highest degree
Another great video. Really like that you own the error & use it constructively, even though they should have trained you better. Learning from our mistakes is the best way in any industry. Thanks & keep up the good work, you are literally helping people who may feel hopeless change their lives.
Thanks
That’s powerful. Take ownership of the mistake and learn from it. A lot of people can’t do that
My biggest mistake.. we machine 3 to 5 ton drums, which are chained down on vee blocks with 3/8 chain, and chain binders you see on semi trucks. The last step is to machine the bulkhead bores which is with a 26.375" bore bar. I had bumped the B axis lever while in jog, and that miniscule amt of time it was bumped, kicked the drum off of B270 degrees. So the bore bar came up to the part, spinning at 110 rpm. With it slightly rotated, the rougher was beating the hell out of the bulkhead so hard that it was picking up the drum off the vee blocks, WHILE chained down! BANG BANG BANG BANG until the spindle was shut down. The drive dogs off the 6" quill, or W (which was extended 18") were sheared off. The 50 taper of the bore bar was WELDED inside the spindle, and wouldnt release. I felt lower than terrible. News like that travels fast across the entire plant. They had to hire guys to come in and re-grind the spindle. Lessons learned,
1. To shut the spindle down, DONT hit feedhold. The spindle keeps spinning. Feedhold shouldn't be a red colored button, its misleading. It just stops the feed. Hit reset or E-stop. Practice it! I've seen people not hit e-stop because they were "afraid". Know where all of your estops are around the machine, and think about what you would do in an emergency.
2. Just above the G0G90G54.1P1X0Y0 start line, add these codes..
G0G91G28Z0W0 (older machines, some of em can crash if they dont start from a Z0 reference point) and G0G90B270. Had these last 2 codes been in the control, while in memory, the machine would have gone back to B270.
Wow!! I have always liked your videos because of quality content, but this video is where I am at. I have downloaded Fusion 360, but made the mistake of selecting the 30 day trial version. I checked the Titans of CNC Academy Forum for the "way out" and get the education version. I am also checking your list of 240 videos to see if there is a video for setting up the Fusion 360 workspace for Lesson M1!
I'm impressed! You have a video for every step of the job! It's a lot to learn, but I am eager to get started! I am specifically looking for the principles that will carry me through every part I make beyond what the academy has to offer.
I was fortunate to have at least one person who could explain machining to me. Every question I had I brought it to him and he took the time to teach me. He is retired and dearly missed.
After the 30 days just go in and register as a Hobbyist. Which will add a year or more
Thank you!! I just received a "Welcome to Fusion 360" email with a link to a video series "to learn foundational concepts of Fusion 360". I don't have internet at home. My fingers are crossed that I can take Fusion 360 with me on my laptop wherever I go. The interconnection of resources to create tutorials brought to one place through videos, documents, software, and other media can be overwhelming at times. I'm a visual person that is building a map in my head of everywhere Titans of CNC: Academy can be found. HA! 3500 affiliates is too big of a map for me!
I've had 3 scrap parts in the last 3 years and gotten written up for 2 of them. I felt absolutely horrible about all of them. With almost 20yrs experience all were stupid mistakes that I should have caught, but got complacent.
I work in a fab shop, we drill these cast aluminum bowls. The company purchased us a gang drill bbn to drill the 2 different sized holes. We only use that drill gang for that part, or so I thought. Well, I checked the drill bit in the first drill press head and it checked out. I didnt check the second...10,000 parts later I completed my work only to find that someone switched the second bit out..should have checked but I didnt know any better, why would it be wrong right? Well that was 2 years ago (still making those parts fo to this day). Eneded up staying after hours redrilling them on my own time! Valuable lesson..ALWAYS CHECK, titan will understand the feeling when I found out they were all wrong..
Started in deburring at the age of 13, was giving a $400 casting and told to deburr the holes. All I knew about was countersinking. So, 10 min later when I had a countersink about 1/4 inch in diameter, I asked if that was deep enough. I still have that wide eyed looked of my supervisor seared into my brain, 22 years later. So, like you Titan, first part I ever touched was scrap. Good vlog.
Check us out @ www.fwmachining.com
I get the reverse at my work, the workshop manager expects deburred edges and holes to look chambered or countersunk.
That was a great video man keep them coming, I have just been moved up to supervisor at my shop and the stuff you put out in these vlogs are so helpful!!! Thanks man BOOM!!!!
Congratulations
May I wish you congratulations from Sydney Australia 🇦🇺
Keep the Faith and God Bless!
Had a similar thing Titan, i had a job to cut bars, i taped 10 together to save time and it worked, but i had to give it to an apprentice to carry on as was too busy, long story short.. All undersize, i got a warning, 3k in material gone
Lesson learned.. Never again
Its just life lessons dude
Please make some videos on how you approach your customers providing them tailor cnc services.
thanks Titan these videos really help me to learn what it takes to make in this trade.
I love to learn, and I also hate to learn. I love learning new things, but I hate the mistakes I make that made me learn.
Whos the editor of this video? You should give them a raise, love the lighting effects during the comments 'murdered'. You should have the screen shake whenever Titan says BOOM!!
Powerful information applicable to any industry. Excellent advice for anyone in management.
Great story. It does leave me wondering if they fired you or just sucked it up as their mistake (which it 75%+ was). You weren't the only one learning a lesson there. My opinion is the only real path to mastery is to acknowledge your mistakes and learn from them. Never blame shift, that just poisons relationships and you won't advance like you should. People respond to a stand-up worker who takes responsibility.
6 months later I would become their head programmer and a year later, the shop foreman. 4 yrs later when I decided to move my family away from the city, Kevin offered to buy me a house if I stayed... Instead he bought me. Kennedy tool box and gave it to me on my last day since I was using his in our shop.
@@TITANSofCNC Awesome. Thanks.
@@TITANSofCNC
Where is that Kennedy box now? That is a pretty darn nice gift.
I work were a single part cost 5,000$ pure titanium, and guess what? So far no scrap. Takes 10 hours to cut.
I dont move a inch from that 5axis machine.
What kind of parts do you manufacture?
@@JoseJimenez-ut2bj Probably aerospace.
at least with steel you can usually weld and repair
I think we all went through this at the beginning, I had my share of oh snap moments learning in this trade. 😊 It's part of the learning process. They def were at fault for not presenting a good inspection process.
thanks for all the tips titan. i would also like to have my own cnc machining company in the future. thanks for all the tips you give in your videos. keep it up you are the best. greetings from the Netherlands.
Kinda left my 1st job because I didn't want to be responsible for plastic parts. When I was their, our department lost quality control inspections. So I had to inspect my own parts. Since it was plastic, it was difficult to get an accurate reading due to the fact plastic likes to flex around a lot and didn't know where to measure the part from the top of the cut or the bottom of the cut since it was cut at an angle.So I was spending an hour inspecting my own parts so I can avoid ruining whole set of parts. To add more salt to the wound, is that my lead didn't want me to spend more than 30minutes inspecting. Little did he know I was autistic. So I had one of my coworker helped me while getting trashed talked that I suck at inspecting. Just bear in mind this was my 1st year. So after a while I got the hang of it, putting it on 123 blocks, angle irons, etc. Then 1 day feeling rushed I accidentally mixed a z dimension on the blueprints and made my part .015in short by mixing the inside dimensional with the outside dimension ruining about 15 parts of plastic with the thermwood 5 axis routers. Moral of the story, take your time even if all your other coworkers are rushing you.
Titan, more great advice.
Over the years I have made some good quality mistakes. Try thread milling and make a nogo gage go, and a go gage not go, and that was not just a couple threads either...That one pops in my head any time i am around thread mills.
I have also been fortunate to have learned some excellent lessons from other peoples mistakes.
I have an off topic question though, what has your CAD-CAM journey been like since you started your company (the different cad-cam packages up to Fusion 360 )?
Fusion just makes everything so much easier and it’s Free for all students.
never send bad parts to customer hoping they might be acceptable or just okay, customers expect on time quality parts at the right price
Again thanks for sharing great information you have a blessed day
T.G. THANK YOU I NEEDED TO SEE THIS.- I REPEAT -NEEDED TO SEE THIS.
I AM THREE WEEKS IN AT NEW JOB AS CNC MACHINIST A TOP COMPANY. THE NEXT FEW WEEKS ARE CRITICAL AS THIS COMPANY HAS DECIDED TO INVEST IN ME AND MY EDUCATION . I SET OUT TO BE IN THIS VERY SPOT OVER A YEAR AGO NO MATTER WHAT LIFE THREW MY WAY. IT WAS A FIGHT I KNOW MANY INCLUDING YOURSELF UNDERSTAND.
MORE IMPORTANTLY I KNOW THAT CARELESSNESS AND AVOIDABLE ERRORS COULD TAKE THE OPPORTUNITY. I WISH I COULD SHARE MY STORY WITH U SOMETIME BUT FOR NOW THANK YOU!! -ALEJANDRA (ALEX) CAZARES
Thx titan for your free stuff, i learn a lot.
How to read a bore gauge seems to be one thing I see people struggle with. Even inspectors. You can say, "do get this?" Yep, yep! And only to find out assembly cant get a bushing in because the bore is too small. Adding to the confusion is bore gauges measuring in micron, vs .01mm or even in inches. And then add to that, setting the bore gauge up off a ring gauge that is way off nominal, because the engineer didnt buy the right size ring gauge for the job. I found it helps to add a plus and minus on the bore gauge face so operators know if the bore is small or big. Some of our parts, I've programmed the probe to check the bore size, but with the length of the stylus we have to run, it's only good to .025mm (and that's with it pre probing a magnetic ring gauge set in a counter bore before it probes the part, to check/set the probes dia accuracy)
Anyways, thanks for sharing!
Quality is not an act,it is a habit!
You are absolutely right. Really very nice and extremely helpful video thank you a lot
I can only add that an entirely handiwork trade like fortepiano building lives and dies on the same premise of quality. The feeling in the motion of tools is the way to make them work without breaking your back - I am today forced to hand plane a very large soundboard to specific thicknesses, something my chaotic cnc machine & vacuum table have failed several times to produce. The trick is to make these machines functional, but it's much harder than normal woodwork, where the tool does tend to train your hands for you. The future beckons, still out of reach.
When I was about 15 years old I was in a similar situation all those parts you murdered was absolutely not your fault your employer / boss failed to give you proper training.
Titan: without quality you have nothing!
CHINA: Hold my beer...
Guys, if you're subbed here and not signed up for the academy, please do so. even if you just like watching, there is no reason not to. It just gives you access to the material, files, etc. all for free. Worst case scenario you don't use it.
Thanks
Titan you a great storyteller. I think I would if melted away if it happened to me.
Our apprentice did something similar..didnt read the drawing properly and assumed the hole he was drilling in over 40 large blocks was in the centre but it was 5mm off centre...He looked so proud when he finished all the blocks 😂 As soon as we looked at one we went have you drilled that in the middle, yeah that's what it says on drawing, so we blew the drawing up so it was about 4ft across 😂 his face was priceless
Painful story, but a good teaching moment
Safety, Quality, Quantity. In that order
Very fine and well explained. Am a convertional machinist and I would like to know about CNC machining. How can I learn practical CNC machining with TiTAN academy? I live in Zambia, Kitwe town, Africa.
Hey Titan! Could you please do a 4140 steel part demo? There is a lot of videos with a wide spectrum of feeds and speed of endmills. But can’t trust them. Your insight on how aggressive can we get with this steel would be great.
I discussed 4140 a few Vlogs back on Machining Hard Materials
TITANS of CNC: Academy ya but that was for drilling. Kindly suggest the feeds and speed for endmilling.
Hey Titan,
Love the vids man. I'm about 6 months in to starting my own shop. Do you have any advice on getting new customers/more work. Thanks,
Nick
I discuss it in my earlier Vlogs and also have a view videos called Building a CNC Shop where I discuss it. Check out this channel and subscribe as I will speak more on it.
You do look like your starting to trim down Titan. Looking good man!
25 pound on KETO... Thanks for mentioning it. I am a night person also, but started waking up at 4:30am to workout. Dedicated
Never lost a customer but have had my but kicked in this trade big time.
mr Titan you are so inspiring.
I have nothing to do with the cnc thematic but its still super interesting. You learn stuff even if u dont need it but hey if its free its free u know maybe there will be this 1 time u can use that learned knowledge in one of your projects.
Hi titan love your videos, I recently went through the same thing got an opportunity to work in a cnc shop, they got me to run parts one at time on the Cnc no measuring tools no paper work, after a while of running them the end mill didn't sound the same, when I spoke to the guy who do the programming he shrugged it off, after that they were all tapered, 3months on I still wasn't taught how to set up the machine and I left the company 😢
Devour our academy.titansofcnc.com
It teaches everything to do with set up, cad and cam
Yeah ...i love quality you are great titan boomm..
another great video. its a shame there is not more common sense training like this.
Crazy..... Things happen for a reason
I remember that happening to one of my guys but instead, he buffed it out of tolerance. The shit hit the fan!!😬😬
True perfect parts . =money and reputation I hate scrap but when working in 10ths you get some so put em in the pile because you never put trash out .
Not only quality, aestetics are extremely important. Parts can be nominal across the board and still look like trash. I know titans parts always look the best, I just thought it was worth mentioning. Customers always gonna go with the suppliers that provide the prettiest parts given that they're same price.
Thanks for the knowledge...
Awesome video, i wish that the shop i work for, understand the importance of the prints.
Without quality there is no customer without customer there is no production without production there is no work & money to be made.
My question is how did you start? A man can dream till you're blue in the face but without money there is no start. So did you start with one small manual mill...or did someone else back you up with their wallet?
What cad/cam software do you use?

Titán I have a question for you. If the employee is failing who’s fall is it? The employee or management?
I think it is important for designers and engineers, to indicate on prints, critical dimensions. Yes, when the print says this is 30 mil, and 5 mil accuracy on all dimensions tolerance somewhere in the corner, you sometimes do not comprehend and register, if this is really important or not. Often this is because it is critical, or sometimes it is because they are simply lazy. A lot of dimensions is not critical, but things like mating surfaces, pins, and fasteners position, and in this case chamfers, were critical. We often think about chamfers just as something cosmetic, and to help handling part. But in many situations the chamfers are the most important geometric feature of the part. And these should be marked as critical directly on the print, right next to a dimension of the chamfer.
