Man titan, im a german 11th grader and at the moment I'm planning to build my very first cnc router for job shop work, to earn money and to educate myself! I don't know how happy I'd be to step in front of a real vmc in a few years :-D Thanks for your awesome inspirational educating content, it helps me a lot to get started in the World of manufacturing! Greetings!
That little bit extra time, setting up, checking to make sure all is right, is what's important in so many industries, but particularly when the tools, machines and equipment you use can do physical harm. Great to see you sharing your experiences with this Titan. Have a great conference!
People come into my CNC workshop here in New Zealand and say "That looks easy to do". I tell them that this is the "Hardest, easiest job in the world !" They see you push the button and the machine does its thing, but they are totally unaware of that in the few seconds they saw you operate, there was a series of precise and exact fundamental procedures that have occurred to be able to perform the said machining task. We have builders next door to us and I say to them "when you drop your hammer, you just pick it up. If we cnc guys drop our hammer, then boom,, 15 grands worth of damage." Puts things into perspective. We like your style Titan down under here in N.Z. and enjoy watching your video logs, keep up the good work !
@@bilalaker8417 Hey there, You have to contact NZ Immigration and find out what appropriate working Visa application forms you need to fill out. Once you know you can get here then I would suggest to use google and find some employment agencies you can register with. Also search NZ engineering jobs and just apply for every job you can. That's all I know about it. There are a lot of people coming here from all over the world for engineering jobs. The younger generation here just don't want to get their hands dirty, they just want to play on their electronic devices all day and night, and that is causing a severe shortage of skilled people across across all trades, we have to import qualified people to keep going. Basically if you have a relevant and recognized qualification, with no criminal history, you can get in here.
Rule number 1 turn your rapid Down always when your proofing a part out Rule 2 set your offset 5 inches above your parts and see if the machine does anything crazy 😜 and you will never crash your machine Remain vigilant 😄😎
I work with some people who start their programs for first time, and just walk away run it at 100%, that stuff gives me anxiety since I used to use 5-axis machines and sometimes in mastercam if you unchack a certain box in the program the machine forgets where it is
@@beyondafx yeah...just trying to learn programming with mastercam myself...uncheck one box somewhere or put in one bit of wrong information and all hell breaks loose...very unnerving
Seriously Titan, i love this stuff. Dont stop. I had a good crash when i was about 18. Tried to change tools in a Willemin and did not have Z in the proper spot. Cracked the tool change arm support casting. $20k in parts and 2 months later we were running again. It was bad. Never heard it from my boss. Thanks boss for not being an asshole.
Not a crash. Just an a premature rapid to an unfavorable location!! I think we have all been there! Another note: Keep these vlogs coming man!! Haha I bet making chips in your shop is so much fun!! Need another set of highly skilled hands???
Thank you for your videos! I love watching and the things that you say! I am grateful for the videos you produce. I've been a machinist on and off for 10+ years, no schooling and you videos help to fill some gaps for me. Thank you!
Converted CAD360 to G-code then uploaded to machine. During the conversation, Z axis was converted to negative infinity. Ran process and end mill went through part and through table, all happened in the blink of an eye, faster then I could push e-stop. From that day I check the code or path before I run.
How is it able to run through the table? That's stupid. Negative infinity or any value below the table should prevent the program from running anyways.
@@CyberlightFG There was a value to Z, but it was very large. And to this day I still cannot figure out how it passed the CNC program stops. When I looked at the CAD path on the machine and Z just kept going negative, I got tired of scrolling and just re-converted it and it ran fine after that. The part was clamped to the table, not in a vise. It was just supposed to be an engraving, not a milling process. Thanks
@@ericed69 You did cool👍. Sooner or later, you need to press that green start button. How much time can you take with checking progs/offsets?? Sometimes the time pressure needs to be considered. Take the gamble occasionally. Usually it pays off. If it doesn't?? Move on and get over it.
Learning machining at the young age of 45! Never too old! I'm lucky to be in a good job with a defense contractor making BIG parts that do AMAZING things! But I know I only have my work ethic and enthusiasm, for now, in place of those bigger bucks! Titans of CNC is keeping me excited and energized for my career! Looking forward to your speech. Good luck in Nashville!
I don't know if I've mentioned this on you're channel but I've mentioned it a few times here & there because it illustrates the danger factor pretty well and if it can ever get anyone to take what you say seriously, all the better. I was about 20, running a pipe trimmer... it' s kinda like a reverse lathe in that it goes around the pipe rather than spinning the pipe or round stock, like cutting a boss with a boring head only the boring head weighs 60 lbs. Anyway, it was shift change and I was told to go run the thing and as far as I knew, it was ready to go but I should have checked it. Apparently the tooling wasn't Titaned down. (pun intended) So it spun up and before I could even react to anything, it had crashed into the protective cage as the head flew off, making a bubble the size of a motorcycle helmet! It only caused a few hundred dollars in damage but if that cage had just been a window or if I hadn't latched it down, as some guys did, for easy access, It would have taken my head clean off ...or left it hanging by a few bloody strings. I've heard of similar crashes when a lathe lets go of the stock during a bad crash. This stuff is no joke and there's reasons that the old guys will rail on the younger guys when they see them doing something that isn't right. It's better you be mad at them than you be missing a limb or dead.
I am a machinist in the Air Force, and one issue that plagues our career field is lack of CNC training. Many of us are either self-taught, or have learned from others. Im proficient at a few CAD programs, but not fusion 360 as of yet. I find myself glued to your channel trying to learn more and more about feeds and speeds, and cutters, and other CNC tips and tricks. This helps me a lot, there are many people in the career field who have not learned CNC because they dont have people are them to train them on it. This is a huge issue for Aircraft Metals Technology career field.
Former Lockheed Martin CNC machinist running 1.1 Million dollar 5 axis Mill turns - machining .000010 in temp controlled room. but we still had the crashes with very experienced people. we all have standards but these machines run so good you get complacent - and then it happens. whammo…..
Being self taught, I've crashed pretty much all my machines. The engineer at Productivity calls it tuition. It's an expensive lesson to learn........Thanks for the videos Titan! I'm going to get my 15 yo watching them so I can put him to work. He can load parts on pallets and swap them, but a deeper understanding would hopefully push him towards the dark side like it did your boy. Keep that videos coming!
Mine is a Hurco VM3. 1 man business. 1 cnc, 1 big Colchester lathe and a surface grinder. I bought and paid for everything. That makes me very careful!
I really like you videos and your story coming up from nothing to something. My expertise is in manual machining and I love it, but I also really enjoy the CNC process and your enthusiasm for teaching the current and new generation in the skills for CNC Machining. Keep up the good work!
The shop I work at we have always had it drilled into us that whenever we are running something new, for the first time in a while or are unsure about something we turn the rapid rate down giving us more reaction time. We also always keep our hand over the "feed hold" till we are certain the machine is running like expected. Usually keep hand over the button till we are confident that the program is running as expected. If Billy had turned the rapid rate down and kept his hand over the feed hold since it was a first run of that job he would have caught the mistake before the machine crashed. Even if he didn't catch it quite in time, the impact wouldn't have been as large. Once confident that the machine is doing as expected, he would then turn up the rapid rates.
On our Brother Speedios, we run quick change pallet systems and if we have the vises mounted on those, it isn't possible to run many programs above the part (there just isn't the Z travel). At 2400IPM rapids and rigid tapping at 6000rpm the pucker factor can be pretty high proving out a program. That said, the biggest risk I see in my shop for crashes are running partial programs, or restarting without safety code (or especially cancelling/calling tool offsets). I love our Tsugami lathe and Swiss machine; they have a handwheel program check feature that is AMAZING since you completely control everything other than synchronized functions (like threading or rigid tapping).
Reminds me of years and years ago in my shop we suffered the biggest crash ever . We had a Miyano ENC 3BC lathe with a mechanical bar feeder . One of my employees was running a repeat job using 1-5/8 diameter 12 ft long bars of Aluminum Silicon Bronze. When BOOM! You had to put a chamfer on the one end so it would be seated into the bar pusher. Well you needed to swing the bar feeder out to the front to load the bar. Put the bar into the feeder then you’d feed the bar through enough so you could chamfer the end. Take it out and turn it around and feed back into the machine. Well this guy forgot what he was doing. He loaded the bar into the machine but completely forgot to put it into the bar feeder . He hit the spindle start and you can just imagine what happened then. Today we only use one long bar feeder on a BNC 34 ( only 1-1/4 diameter capacity) which has the same type feeder. We use it for jobs that a magazine feeder would simply waste too much material. But for other jobs the LNS magazine bar feeders take away the chance for a big BOOM ! And just so you know I didn’t fire that guy. However he didn’t get a raise for quite some time ;)
Mr. Titan, Sr. I always watching your vlog, and i learn a lot from your advice and technic the way you operate cnc machine. Im also a cnc machinist. I am. ofw. Away from my country . Thank you sr. Titan boomm
Did the same many years ago but on a bending machine. Was putting 90 degree bends in some 1mm mild steel. Went to close the gap whilst chatting to a colleague and pressed the wrong button and the top piece rammed into the bottom die and caused it to explode. Hardened steel to the body is no joke. Somehow it had set to -100mm and instead of pressing the joggle button i hit send.....my boss was not happy.
I alternate lately between a very large CNC router and a large CNC mill with bt50 collets. That mill has some serious grunt which I found out when a high speed steel 30mm twist drill exploded though too higher feed rate. The mill makes me nervous but I've seen the most expensive damage done to CNC routers because their construction is more in keeping with their normal operating loads and the other thing is the material being machined catching fire usually due to saw dust getting compacted into corners during deep pocketing. I've seen a 6 meter long table router burnt to the ground during over night machining and a 5 axis router's spindle dangling by one remaining cap screw after selecting a tool much longer than intended and trashing itself to death on the springy safety guard at the side of the table. The tool in question was over a foot long so it imparted plenty of leverage back to the spindle.
I had unlocked my z axis on a mill with flycutter and it slipped down a bit because the airspring decided to engage the gears fully for z travel and 💥🤯 bent the flycutters hex screws totally through the tool shattered the gears between motor and gearbox but I'm so glad I finally had a good reason to get the belt drive and I love its silence and anymore crashing it'll just slip. Also I never flycut or mill at all without locking the z now lol Also removed airspring so no longer have any z travel runout which eats tools alive
Man I love watching the smaller more highly detailed parts being machined, did my apprenticeship in a small high precision work place, there was only 4 of us who worked there, after that I moved into heavy engineering, machining multi tonne parts for ships and oil rigs, don't get me wrong I love what I do but nothing compares to a 5 axis machine at full speed
I haven’t crashed my machine....yet but iv had a few times running Blanchard forgetting to turn on the magnetic chuck. You start to remember really quick when everyone and looking at you and on top of that all your abrasives are shattered and you gotta change a whole set. Good times
In my first year I made an adjustment on a Hurco in the wrong tool offset page and literally made the tool go straight into the table. I never did it again and I've never crashed like that again.
Had some "BOOMS", Seen some "BOOMS".....been there done that. Titan, I made a setup check list back in 1998 for my team to set up our Matsurra RA3's and Haas VMCs. It was comparable to yours. Most of my team had it memorized and knew it covered the bases and knew they couldn't explain a crash away if they skipped anything. I had to police the young peeps to use them.
Sorry, had a neighbor crash his machine because he was using his CNC machine to cut a stock down (I told him I would let him use my bandsaw for this work, would be faster and less risky). He clamped the stock into the vise, and set the G54 to suit. Then he finishes cutting and puts the previous part back on, and forgetting to change the G54 back, the face mill promptly crashed into the bottom of the stock rather than top. He's such a big believer in CNC that he thinks to use them to do all things, but I think leave CNC for complex stuff, or rather not disturb the setup for unnecessary things. I mean he didn't really damage anything serious, just it obviously tore the stock from the vise and the face mill cut into the soft jaw, but it still meant losing 30 minutes to replace the soft jaw and double checking the offsets to resume the job. That and sometimes I don't like M00 because it's easy (especially when watching multiple machines) to forget a M00 is active and so a part could sit there waiting because you did not see the light changing to yellow. So that's a lot of lost time. My bandsaw is for cutting wood but it is fully capable of cutting aluminum too.
When I was just learning G code they said go ahead and put some aluminum in that machine and carve it up. It will be good practice. But no one watched over me. My finger hovered over the cycle start button, did I do it right...........push, BAM! 3 inch shell mill rapids at an angle down onto the vise. What a horrendous noise. lol
Last week we crash the tool changer. We were setting up a new control on the VF-1. And the program was quite right the head went down instead of going up. After a few hours of repair we are back running. Not a good feeling , Bob RJ Machine
Saw a table flying thru the shop with all the parts and stuff that was on it, when guy reload a bar stock in lathe. Material was bit too long, about 3 ft was sticking out of the back of the spindle. First op was facing with M50 S4000.
Hell yeah. Kung Fu was the bomb! Honestly, I’ve never crashed a machine while setting up. I’ve always just lowered my feed, ran through the part with the handle, watch my program, my numbers, and used common sense. Those extra few minutes pay for them self by the end of job.
I always use rapid override on a setups first cycle. I also watch the travel to distance on my readout. If I make an offset change I again just in case I was off on a decimal place I will again use rapid override. Older Fanuc controls only allow 25% but.... I have not programmed myself but would I be nervous if I did if a decimal was out of place on a feed or and axis.
Titan, I love your outlook on life and the trades. You're a good guy that just fucked up. It's amazing how stupid CNC machines are. It's 2018, and they still don't know not to crash into the table! I understand crashing into stock or a vise can happen, but the table!?!? (Even crashing into stock or the vise should be eliminated by now.)
I've had only one in my first years on a DMU50-T. A faulty sensor in TC (16 fixed tools) caused it to not allign right to change tool. It rammed it in there destroying pockets 3 and 4, everything mangled. Especially when you don't expect something like that to happen, had to sit down for a sec like wtf?? hahaha
machines should have a "lowest point for every tool in the program" feature that you can run for every tool that you can check before starting. I Have a similar feature in a multispindle/chuck lathe that i work with. I can set a stop in the program so you can jog the tool in a given axis so it reach it's lowest point in that given axis for that given program without running the spindle or anything else. Also where i work we have tools and tool holders for every single part we run, that way we never have to change tool offsets.
Titan, bring that kid from Germany over for a 6 month hands on apprenticeship. Sounds like a go-getter and your expertise could serve him well for many years.
12:43 Someone says hi while I'm cranking the mill...It's back to 0 until he's gone! There is also the case when you try to get the feel and sound of something tiny like a microdrill while someone is going to town with a hammer next to you and it just sucks cause you can't always wait it out.
if you need a good explanation of always being on your toes, here's one for you. i had set up a milti-axis part, 3 axis working while indexing the 4th and 5th. i didn't have the exact right post for mastercam and found a work around, which was to run the 4th axis in mirror image. 3rd day of running, machine was coming back from a full shutdown as we didnt run weekends. never re-zeroed the 4th axis but left mirror image on. it was parked at 45* facing the operator. i should note this machine has absolute encoders on it so going to reference return was not part of the normal startup procedure. when bringing the machine up, the absolute position for the 4th axis was 0, not 45. it went an additional 45* to total 90*.after warmup, ready to run the part, the operator hit cycle start, about .5 seconds after tool change the 2.5 inch shell mill buried into the trunnion at full rapid. moral of the story, always double-check and drive slow till you have a good part off for the first time that day.
Any machinist who hasn’t had a crash is either not doing anything or a lair. Mistakes happen just got to minimise them and make sure it’s not a regular occupancy.
swikocki that isn’t true. I’ve been machining for 16 years and never crashed a machine. At my old shop I worked from putting chamfers on bars to being general manager. I currently own my own shop. I wouldn’t say I never did anything and I’m definitely not lying. Some people actually don’t crash a machine.
Hi Titan, I'm the Programmer and an Operator at my work. My employer has recently invested in a few more CNC machines, and we're trying to looking into a way of linking the machine into some sort of software via the Ethernet network to monitor the Setup, Cycle, Down time, etc. of each machine. But seemed to be limited with our Industry 4.0 options in Australia. Do you monitor your CNC's remotely or collect data? if so do you have any recommendations?
Soo titan , how would you recommend I go about starting my own shop ? Is there any financial things I should be an eye out for ? How should I go about acquiring cnc machines. I've always had a dream to work aerospace , it's been in the family and I have a passion for it .
@TITANS of CNC: Academy AWESOME you are taking camera to DMC (can't wait!). You guys do cnc milling (up to 5 axis) and 4th axis mill turn and turning; however for higher tolerance key surfaces that have to be referenced it seems that surface grinding, lapping and use of cylindrical grinders / universal ID/OD grinding still needs to be known or understood. Any chance you guys in the future might teach some of those techniques in your academy ?
@@TITANSofCNC The core of innovation demands a smidge broader skill set for actually making/ manufacturing stuff. Higher tolerances are directly related to high standards of living and capability/technical excellence (As you know/Grandma's sucking eggs etc.). "Peeps" need to build stuff that works (in the USA) not just make individual parts that are passed onto someone else. I think 0.0002" is a good rule (especially for ferrous alloys), unfortunately these higher tolerances are not going away and fifteen years from now more so (hydrodynamic bearings and the like) as well as more demanding precision reference surfaces. That kind of knowledge and craft is dying out and is needed more than ever.
Hi Titan, question--what sort of stone would you recommend for stoning a mill table? Everyone I've seen simply refers to them as a 'stone' and not where they got it or what its composition is. I bought a Norton aluminum oxide fine/coarse stone but it seems way more coarse than anything I would want to touch the table with. Do you have a recommendation of a source/brand/type of stone? Thanks for the help, keep up the great videos!
I have used the Norton fine/rough and the fine isn’t bad... just can’t put pressure on it... keep it smooth. We have some different ones but I am in Nashville right now... will look when I get back.
With this step of 'stoning the table' you aren't trying to grind or change the table. You are detecting if any dings have happened which will be a high point when you put any job or set up on top of it. I hope that helps.
@@captcarlos thank you for your reply--yes, that is why I was asking, because the Norton stone is aggressive and not necessarily flat, I was concerned that using it on the table would in fact remove material from the surface, not just the burrs. If I am careful I'm sure it's fine, but I was wondering if those more experienced had a stone (brand, composition, etc.) they preferred to use. Do you have a recommendation?
There is nothing wrong with the Norton fine. You want to use a 'true' stone. They can be Tryed on a diamond impregnated block or such. I would get a new stone, keep it for that purpose and Gard it with my life... Do not lend it out.
I understand what thats like, just two weeks ago i crashed a tool of my VF2 into the work, had to replace the spindle, 12000€/14000$ damage. Did not feel good at all
Hi titan...talking about crashing machines..I know modern machine are more inteligent and avoid crashing..but there is some issues about the exchanger tool palet..i want to ask can i execute M06 at any z level..thanks
Worst crash i ever had was in a lathe.. i was getting my certificates and mangled the part ro hell.. lathe has to be programmed manually, old thing, but good for experience sake. Didnt lift tool off part, shifted magazine out of center, and made the whole tool turn out of alignment. Was a bad day to be fair..
I filled my shorts when I traversed the spindle on my horizontal borer into the machine bed, that split second of panic and adrenaline before you hit the E-Stop 🤮🤮, all because I programmed a negative Y movement by accident
Halooo, I relate 100% to this. But..... one day, another crunch will happen! And when it happens the reason will be analysed. And the cause will be so obviously simple and preventable. The operator/programmer/setter will slap themself in the face! 🤣. And do it again in a few years time. I've been very lucky (Or conscientious)? My worst was the complete destruction of a 2 inch Kaiser boring head. I was devastated. It wiped out the fixture as well. Oh well. Get over the accidents, get back on the job. But never be complacent either.
Two things I have learned. 1. Never work when you are tired. 2. Never let someone distract you from your process. You never said what he actually did wrong? Was he distracted by your comment?
I saw a guy blow the door off of a haas lathe when i was taking a night course. He forgot the g50 max speed line. Took a facing cut and it hit machine max rpm and let go of a big chunk of steel. BOOM.
I almost did that, spindle was almost maxed out at 6000 rpm as the turret was rapiding to the part, spindle over ide was set to 0 pretty quick and feed stop lol
I crashed 3D setter Haimer cause wrong select axis to move when pick center... and that realy shocked moment in my CNC experience... and after that i hope never wrong select axis again
Id love to look over the shoulder of a experienced cnc operator and coder.. im getting quite proficient with manual machines, however if you want to make a business in machining you really need cnc...i just cant understand these videos.. i have to many questions
Why arent there perimeter warnings in the software that know in advance when the Software vs actually causes a fault that wont allow the machine to start
Victor and the Psalter nice! I bought a Citizen L32 Xll not long ago and just started my own place. I’ve worked with citizens since 2003. Where are you guys at? M machine is nice. I wanted to buy one, but it was just too much machine for me to start the shop with. I could have justified the extra 300k if I had a huge family of similar parts. Maybe one day though.
It’s a check list for our academy parts at academy.titansofcnc.com Go to Education Then building blocks Then click a part. Then video And it will be in related files to the right
Tell ya what man, I was pretty negative of this channel when I first came across it maybe 3 years ago, but you've changed my opinion. You guys have a really good educational resource thing going, I dont always agree with how you guys do what you do but, I appreciate what this has become and the value that you guys are putting out for viewers or young guys just getting started is great, both on the machining end and entrepreneur end. Thanks 👍

This stuff is no joke and there's reasons that the old guys will rail on the younger guys when they see them doing something that isn't right. It's better you be mad at them than you be missing a limb or dead.
I am a machinist in the Air Force, and one issue that plagues our career field is lack of CNC training. Many of us are either self-taught, or have learned from others. Im proficient at a few CAD programs, but not fusion 360 as of yet. I find myself glued to your channel trying to learn more and more about feeds and speeds, and cutters, and other CNC tips and tricks. This helps me a lot, there are many people in the career field who have not learned CNC because they dont have people are them to train them on it. This is a huge issue for Aircraft Metals Technology career field.
Thats a thing? To machine fpr tge air Force?
Former Lockheed Martin CNC machinist running 1.1 Million dollar 5 axis Mill turns - machining .000010 in temp controlled room. but we still had the crashes with very experienced people. we all have standards but these machines run so good you get complacent - and then it happens. whammo…..
Being self taught, I've crashed pretty much all my machines. The engineer at Productivity calls it tuition. It's an expensive lesson to learn........Thanks for the videos Titan! I'm going to get my 15 yo watching them so I can put him to work. He can load parts on pallets and swap them, but a deeper understanding would hopefully push him towards the dark side like it did your boy. Keep that videos coming!
Mine is a Hurco VM3. 1 man business. 1 cnc, 1 big Colchester lathe and a surface grinder. I bought and paid for everything. That makes me very careful!
Watching in northern Ireland 🇬🇧 , good to see what hard work can achieve 🤙
I really like you videos and your story coming up from nothing to something. My expertise is in manual machining and I love it, but I also really enjoy the CNC process and your enthusiasm for teaching the current and new generation in the skills for CNC Machining. Keep up the good work!
The shop I work at we have always had it drilled into us that whenever we are running something new, for the first time in a while or are unsure about something we turn the rapid rate down giving us more reaction time. We also always keep our hand over the "feed hold" till we are certain the machine is running like expected. Usually keep hand over the button till we are confident that the program is running as expected.
If Billy had turned the rapid rate down and kept his hand over the feed hold since it was a first run of that job he would have caught the mistake before the machine crashed. Even if he didn't catch it quite in time, the impact wouldn't have been as large. Once confident that the machine is doing as expected, he would then turn up the rapid rates.
On our Brother Speedios, we run quick change pallet systems and if we have the vises mounted on those, it isn't possible to run many programs above the part (there just isn't the Z travel). At 2400IPM rapids and rigid tapping at 6000rpm the pucker factor can be pretty high proving out a program. That said, the biggest risk I see in my shop for crashes are running partial programs, or restarting without safety code (or especially cancelling/calling tool offsets). I love our Tsugami lathe and Swiss machine; they have a handwheel program check feature that is AMAZING since you completely control everything other than synchronized functions (like threading or rigid tapping).
Reminds me of years and years ago in my shop we suffered the biggest crash ever . We had a Miyano ENC 3BC lathe with a mechanical bar feeder . One of my employees was running a repeat job using 1-5/8 diameter 12 ft long bars of Aluminum Silicon Bronze. When BOOM! You had to put a chamfer on the one end so it would be seated into the bar pusher. Well you needed to swing the bar feeder out to the front to load the bar. Put the bar into the feeder then you’d feed the bar through enough so you could chamfer the end. Take it out and turn it around and feed back into the machine. Well this guy forgot what he was doing. He loaded the bar into the machine but completely forgot to put it into the bar feeder . He hit the spindle start and you can just imagine what happened then. Today we only use one long bar feeder on a BNC 34 ( only 1-1/4 diameter capacity) which has the same type feeder. We use it for jobs that a magazine feeder would simply waste too much material. But for other jobs the LNS magazine bar feeders take away the chance for a big BOOM ! And just so you know I didn’t fire that guy. However he didn’t get a raise for quite some time ;)
And then BOOOOOM,titan is THE story teller, his story telling is on point.
I commented before the end of video. I just wanted to say thanks for taking us with you. I look forward to watching.
Mr. Titan,
Sr. I always watching your vlog, and i learn a lot from your advice and technic the way you operate cnc machine. Im also a cnc machinist. I am. ofw. Away from my country . Thank you sr. Titan boomm
Did the same many years ago but on a bending machine. Was putting 90 degree bends in some 1mm mild steel. Went to close the gap whilst chatting to a colleague and pressed the wrong button and the top piece rammed into the bottom die and caused it to explode. Hardened steel to the body is no joke. Somehow it had set to -100mm and instead of pressing the joggle button i hit send.....my boss was not happy.
I alternate lately between a very large CNC router and a large CNC mill with bt50 collets.
That mill has some serious grunt which I found out when a high speed steel 30mm twist drill exploded though too higher feed rate.
The mill makes me nervous but I've seen the most expensive damage done to CNC routers because their construction is more in keeping with their normal operating loads and the other thing is the material being machined catching fire usually due to saw dust getting compacted into corners during deep pocketing.
I've seen a 6 meter long table router burnt to the ground during over night machining and a 5 axis router's spindle dangling by one remaining cap screw after selecting a tool much longer than intended and trashing itself to death on the springy safety guard at the side of the table.
The tool in question was over a foot long so it imparted plenty of leverage back to the spindle.
I had unlocked my z axis on a mill with flycutter and it slipped down a bit because the airspring decided to engage the gears fully for z travel and 💥🤯 bent the flycutters hex screws totally through the tool shattered the gears between motor and gearbox but I'm so glad I finally had a good reason to get the belt drive and I love its silence and anymore crashing it'll just slip. Also I never flycut or mill at all without locking the z now lol
Also removed airspring so no longer have any z travel runout which eats tools alive
I like hearing about crashes. It helps me be stay cautious/ humble. Respect your machine, it’s your baby. Take care of it so it can take care of you.
Set your G54 check zero in absolute, run tools 5 inches away before cutting the part, run in single block and watch your numbers.
Man I love watching the smaller more highly detailed parts being machined, did my apprenticeship in a small high precision work place, there was only 4 of us who worked there, after that I moved into heavy engineering, machining multi tonne parts for ships and oil rigs, don't get me wrong I love what I do but nothing compares to a 5 axis machine at full speed
I haven’t crashed my machine....yet but iv had a few times running Blanchard forgetting to turn on the magnetic chuck. You start to remember really quick when everyone and looking at you and on top of that all your abrasives are shattered and you gotta change a whole set. Good times
An inspirational video that's for sure I am trying to learn cnc machining a little at a time I am past my prime but I still enjoy the challenge.
I have 80 yr olds enjoying our Academy.titansofcnc.com
In my first year I made an adjustment on a Hurco in the wrong tool offset page and literally made the tool go straight into the table. I never did it again and I've never crashed like that again.
As long as no one gets hurt. You can always get a machine repaired. We had a magnesium fire in a Fadal 3020, total loss.
Had some "BOOMS", Seen some "BOOMS".....been there done that. Titan, I made a setup check list back in 1998 for my team to set up our Matsurra RA3's and Haas VMCs. It was comparable to yours. Most of my team had it memorized and knew it covered the bases and knew they couldn't explain a crash away if they skipped anything. I had to police the young peeps to use them.
Sorry, had a neighbor crash his machine because he was using his CNC machine to cut a stock down (I told him I would let him use my bandsaw for this work, would be faster and less risky). He clamped the stock into the vise, and set the G54 to suit. Then he finishes cutting and puts the previous part back on, and forgetting to change the G54 back, the face mill promptly crashed into the bottom of the stock rather than top.
He's such a big believer in CNC that he thinks to use them to do all things, but I think leave CNC for complex stuff, or rather not disturb the setup for unnecessary things.
I mean he didn't really damage anything serious, just it obviously tore the stock from the vise and the face mill cut into the soft jaw, but it still meant losing 30 minutes to replace the soft jaw and double checking the offsets to resume the job.
That and sometimes I don't like M00 because it's easy (especially when watching multiple machines) to forget a M00 is active and so a part could sit there waiting because you did not see the light changing to yellow. So that's a lot of lost time.
My bandsaw is for cutting wood but it is fully capable of cutting aluminum too.
When I was just learning G code they said go ahead and put some aluminum in that machine and carve it up. It will be good practice. But no one watched over me. My finger hovered over the cycle start button, did I do it right...........push, BAM! 3 inch shell mill rapids at an angle down onto the vise. What a horrendous noise. lol
I really understood the message in this video today. I am really looking forward to seeing footage from the DMC here soon. BOOM!
It was insane.. video coming in the next 2 weeks
Your story on experience is spot on !
Last week we crash the tool changer. We were setting up a new control on the VF-1. And the program was quite right the head went down instead of going up. After a few hours of repair we are back running. Not a good feeling , Bob RJ Machine
Saw a table flying thru the shop with all the parts and stuff that was on it, when guy reload a bar stock in lathe. Material was bit too long, about 3 ft was sticking out of the back of the spindle. First op was facing with M50 S4000.
Yup!!! Been there!! 😂😂😂
All you can do is laugh!!!
Hell yeah. Kung Fu was the bomb! Honestly, I’ve never crashed a machine while setting up. I’ve always just lowered my feed, ran through the part with the handle, watch my program, my numbers, and used common sense. Those extra few minutes pay for them self by the end of job.
I always use rapid override on a setups first cycle. I also watch the travel to distance on my readout. If I make an offset change I again just in case I was off on a decimal place I will again use rapid override. Older Fanuc controls only allow 25% but.... I have not programmed myself but would I be nervous if I did if a decimal was out of place on a feed or and axis.
The face priceless on a crash lol, always it's like it's still hitting inside my head
I'm a brake press programmer/ operator working with trumpf and bystronic machines 😎
Measure twice. Cut once. Works with more than just CNC ;)
Titan, I love your outlook on life and the trades. You're a good guy that just fucked up. It's amazing how stupid CNC machines are. It's 2018, and they still don't know not to crash into the table! I understand crashing into stock or a vise can happen, but the table!?!? (Even crashing into stock or the vise should be eliminated by now.)
I've had only one in my first years on a DMU50-T.
A faulty sensor in TC (16 fixed tools) caused it to not allign right to change tool.
It rammed it in there destroying pockets 3 and 4, everything mangled.
Especially when you don't expect something like that to happen, had to sit down for a sec like wtf?? hahaha
machines should have a "lowest point for every tool in the program" feature that you can run for every tool that you can check before starting. I Have a similar feature in a multispindle/chuck lathe that i work with. I can set a stop in the program so you can jog the tool in a given axis so it reach it's lowest point in that given axis for that given program without running the spindle or anything else. Also where i work we have tools and tool holders for every single part we run, that way we never have to change tool offsets.
Charisma!! enthusiastic!!!
Motivational speaker! Awesome!
Titan, bring that kid from Germany over for a 6 month hands on apprenticeship. Sounds like a go-getter and your expertise could serve him well for many years.
12:43 Someone says hi while I'm cranking the mill...It's back to 0 until he's gone! There is also the case when you try to get the feel and sound of something tiny like a microdrill while someone is going to town with a hammer next to you and it just sucks cause you can't always wait it out.
I tell all my students to "practice extreme caution", bc you can never be too safe 👌
if you need a good explanation of always being on your toes, here's one for you.
i had set up a milti-axis part, 3 axis working while indexing the 4th and 5th. i didn't have the exact right post for mastercam and found a work around, which was to run the 4th axis in mirror image. 3rd day of running, machine was coming back from a full shutdown as we didnt run weekends. never re-zeroed the 4th axis but left mirror image on. it was parked at 45* facing the operator. i should note this machine has absolute encoders on it so going to reference return was not part of the normal startup procedure. when bringing the machine up, the absolute position for the 4th axis was 0, not 45. it went an additional 45* to total 90*.after warmup, ready to run the part, the operator hit cycle start, about .5 seconds after tool change the 2.5 inch shell mill buried into the trunnion at full rapid.
moral of the story, always double-check and drive slow till you have a good part off for the first time that day.
A TH-cam video hasn’t made me laugh like that in a while, thanks for that BOOM 💥
Any machinist who hasn’t had a crash is either not doing anything or a lair. Mistakes happen just got to minimise them and make sure it’s not a regular occupancy.
swikocki that isn’t true. I’ve been machining for 16 years and never crashed a machine. At my old shop I worked from putting chamfers on bars to being general manager. I currently own my own shop. I wouldn’t say I never did anything and I’m definitely not lying. Some people actually don’t crash a machine.
Great personality makes a great video. Nice work
Hi Titan, I'm the Programmer and an Operator at my work. My employer has recently invested in a few more CNC machines, and we're trying to looking into a way of linking the machine into some sort of software via the Ethernet network to monitor the Setup, Cycle, Down time, etc. of each machine. But seemed to be limited with our Industry 4.0 options in Australia. Do you monitor your CNC's remotely or collect data? if so do you have any recommendations?
Soo titan , how would you recommend I go about starting my own shop ? Is there any financial things I should be an eye out for ? How should I go about acquiring cnc machines. I've always had a dream to work aerospace , it's been in the family and I have a passion for it .
Just did my first crash. Now I can't stop feeling like crap
It happens to everyone. Learn from it. Could be the best thing for this industry. Never get too confident, double check everything always
@@TITANSofCNC thanks for your kind words, sir. It really means a lot to me. 👍
@TITANS of CNC: Academy AWESOME you are taking camera to DMC (can't wait!). You guys do cnc milling (up to 5 axis) and 4th axis mill turn and turning; however for higher tolerance key surfaces that have to be referenced it seems that surface grinding, lapping and use of cylindrical grinders / universal ID/OD grinding still needs to be known or understood. Any chance you guys in the future might teach some of those techniques in your academy ?
Yes on the camera at DMC and anything under .0002 is ground
@@TITANSofCNC The core of innovation demands a smidge broader skill set for actually making/ manufacturing stuff. Higher tolerances are directly related to high standards of living and capability/technical excellence (As you know/Grandma's sucking eggs etc.). "Peeps" need to build stuff that works (in the USA) not just make individual parts that are passed onto someone else. I think 0.0002" is a good rule (especially for ferrous alloys), unfortunately these higher tolerances are not going away and fifteen years from now more so (hydrodynamic bearings and the like) as well as more demanding precision reference surfaces. That kind of knowledge and craft is dying out and is needed more than ever.
With any luck they will let you video the talk and publish it here!
Turn the rapids down..... the checklist is perfect corrective action.
Dang, was hoping for video of the crash...
Awesome to know your coming to Nashville finally but i can’t go.
Hi Titan, question--what sort of stone would you recommend for stoning a mill table? Everyone I've seen simply refers to them as a 'stone' and not where they got it or what its composition is. I bought a Norton aluminum oxide fine/coarse stone but it seems way more coarse than anything I would want to touch the table with. Do you have a recommendation of a source/brand/type of stone? Thanks for the help, keep up the great videos!
I have used the Norton fine/rough and the fine isn’t bad... just can’t put pressure on it... keep it smooth. We have some different ones but I am in Nashville right now... will look when I get back.
@@TITANSofCNC Thanks Titan! Really appreciate that you are here in our back pockets. Means a lot. Looking forward to whatever you find.
With this step of 'stoning the table' you aren't trying to grind or change the table. You are detecting if any dings have happened which will be a high point when you put any job or set up on top of it. I hope that helps.
@@captcarlos thank you for your reply--yes, that is why I was asking, because the Norton stone is aggressive and not necessarily flat, I was concerned that using it on the table would in fact remove material from the surface, not just the burrs. If I am careful I'm sure it's fine, but I was wondering if those more experienced had a stone (brand, composition, etc.) they preferred to use. Do you have a recommendation?
There is nothing wrong with the Norton fine. You want to use a 'true' stone. They can be Tryed on a diamond impregnated block or such. I would get a new stone, keep it for that purpose and Gard it with my life... Do not lend it out.
I understand what thats like, just two weeks ago i crashed a tool of my VF2 into the work, had to replace the spindle, 12000€/14000$ damage. Did not feel good at all
Same shit. Yesterday I crashed waycower(Zaxis) on VF3. Not such a big price though.
Im dreaming to become one of your student in your academy one day. Thank you sr. Godblesss
Hi titan...talking about crashing machines..I know modern machine are more inteligent and avoid crashing..but there is some issues about the exchanger tool palet..i want to ask can i execute M06 at any z level..thanks
Snatch the pebble from my hand! Love it. I grew up on Kung Fu too. 😅
Worst crash i ever had was in a lathe.. i was getting my certificates and mangled the part ro hell.. lathe has to be programmed manually, old thing, but good for experience sake. Didnt lift tool off part, shifted magazine out of center, and made the whole tool turn out of alignment. Was a bad day to be fair..
I filled my shorts when I traversed the spindle on my horizontal borer into the machine bed, that split second of panic and adrenaline before you hit the E-Stop 🤮🤮, all because I programmed a negative Y movement by accident
A lot of people at my work don’t even bother to clean up after themselves, let alone care about the machines.
I made aerospace parts for Boeing and Lockheed Martin
Titan what is the best way to size holes under .5 of an inch In hard materials reamers boring mills
Can't wait to see the DMC vids...
Halooo, I relate 100% to this. But..... one day, another crunch will happen! And when it happens the reason will be analysed. And the cause will be so obviously simple and preventable. The operator/programmer/setter will slap themself in the face! 🤣.
And do it again in a few years time. I've been very lucky (Or conscientious)?
My worst was the complete destruction of a 2 inch Kaiser boring head. I was devastated. It wiped out the fixture as well. Oh well.
Get over the accidents, get back on the job. But never be complacent either.
This has to happen. Sooner or later. Nice to see the suck side of things.
Two things I have learned.
1. Never work when you are tired.
2. Never let someone distract you from your process.
You never said what he actually did wrong? Was he distracted by your comment?
Made a wrong Z zero Offset
I saw a guy blow the door off of a haas lathe when i was taking a night course. He forgot the g50 max speed line. Took a facing cut and it hit machine max rpm and let go of a big chunk of steel. BOOM.
I almost did that, spindle was almost maxed out at 6000 rpm as the turret was rapiding to the part, spindle over ide was set to 0 pretty quick and feed stop lol
I crashed 3D setter Haimer cause wrong select axis to move when pick center... and that realy shocked moment in my CNC experience... and after that i hope never wrong select axis again
Same
I thought CNC is too perfect but it does repairs sometimes, I'm a welder
Single block on.
Coolant off.
Distance to go.
Feed rate 10%
just writing to support (Y)
Id love to look over the shoulder of a experienced cnc operator and coder.. im getting quite proficient with manual machines, however if you want to make a business in machining you really need cnc...i just cant understand these videos.. i have to many questions
Go to the academy.... Dowload fusion ... And it will be a start...
Why arent there perimeter warnings in the software that know in advance when the
Software vs actually causes a fault that wont allow the machine to start
Don't miss Bolton's Hot Chicken in Nashville!
Exactly !
Crashing is preventible.. but I don’t care how good you are... sooner or later it will happen.
-What you done?
-I just push a buton...
Operater?
@@neilwoodward7336 something like it
What step did the guy screw up on?
Is it normal that i build up or just say repair damage machined part, is this happened there in the US?
Any vids on swiss cnc machining?
Victor and the Psalter I have a Swiss. I was thinking of starting a channel on the topic. I’ll probably start after the holidays. New to Swiss?
@@cliffordernest7825 thanks. I worked with swiss for about 3yrs. Love it. I am a citizen b12 and m guy.
Victor and the Psalter nice! I bought a Citizen L32 Xll not long ago and just started my own place. I’ve worked with citizens since 2003. Where are you guys at? M machine is nice. I wanted to buy one, but it was just too much machine for me to start the shop with. I could have justified the extra 300k if I had a huge family of similar parts. Maybe one day though.
@@cliffordernest7825 I am overseas. I love Ls they are more user-friendly.
Check out my video “Biggest CNC Shop in Switzerland”
So what is THE checklist?
It’s a check list for our academy parts at academy.titansofcnc.com
Go to Education
Then building blocks
Then click a part.
Then video
And it will be in related files to the right
Tell ya what man, I was pretty negative of this channel when I first came across it maybe 3 years ago, but you've changed my opinion. You guys have a really good educational resource thing going, I dont always agree with how you guys do what you do but, I appreciate what this has become and the value that you guys are putting out for viewers or young guys just getting started is great, both on the machining end and entrepreneur end.
Thanks 👍
Watched a tool turret get ripped off indexed into a "tombstone" broke to fixtures to.. guy forgot a g28 or 3
You wont know what PTSD is until you have your first REAL crash.. Shit will haunt you for the rest of your life
🙏 never take anything for granted. Or Assume. Because if you do that you make an, ASS out of U & ME.

All must know
Hard to teach
Remember SINGLE BLOCK, and don’t walk,
Never go 100% rapid on a 1st part lol, 25 and watch the distance to go for me
