Steel Flanges Drilled & Tapped

- I received a small batch of 6 steel flanges that needed two sets of bolt hole patterns drilled and drilled & tapped. This was a great opportunity to continue learning how to use Fusion 360 to create a CAM program to machine these parts. We used the @MilltronicsUSAInc TRM3016 to complete this job and it worked out great. When I tackle these jobs with the cnc machine I am always learning something new, either from the outcome or the mistakes I made along the way.

When performing this type work I always prefer to have the retract height set to approx. 2" to clear all the clamps, you are doing great!
In 1981 I was an engineering student at Southern Tech in Marietta, Georgia. One of my instructors had married together a milling machine with a rudimentary computer that was programmed by holes in paper tape. At that point all it would do is make monogrammed belt buckles. CNC has come a long way! ……although, now that I think of it, that was 43 years ago. I’m so old.
I'm trying to think of the name for the paper punched controlled machines, they are the pre cnc. The first two letters are NC but I can't think of the third letter. Stands for numeric control. I think CNC stands for computer numeric control. It's been 30 years
I set up and ran old Cincinnati Cintematic NC mills for a few years when I first started in the trade in '79. It used punch tape, operator changed the tools. Tool height and feed depths were controlled by preset cam operated hydraulic stops on a big drum. Sometimes we used really long tapes or had to switch a couple of tapes for one piece. We had lots of long running parts. We also inspected each other's set ups and new parts to prove them out.
Later we got incredible big and powerful 3 axis Matsuuras. My favorite CNCs of all time. These ran on tape or software.
If one guy could both set up and keep 3 machines running 75% of the time we'd be paid double time or a bit less for lower run times.
On night shift we'd often play ping pong most of the night, work up a good sweat and keep all those machines going. Just 2-4 of us running 1/2 the entire machine shop. We also got shift differential pay so the lazy day shift could blame their f-ups on us! 😂 We rarely needed to deal with our bosses, who were only bosses because they couldn't hack this easy work. Mere politicians.
We had the ping pong table set up on a 4'x 8' granite surface plate in the middle of the shop. We couldn't cheat and move the table! We even snuck beer past the security guards.
That was a sweet job until the Cold War ended.
are you following new technology like metal 3D printing?
@@rodiona8781 Nah, I'm retired and 'devolving'! 🤣 Even though I'll probably never fully retire and stop doing what I do. I just work for myself now and it's mostly for fun, to keep 'out of trouble'!
DIY was passed down in my family for generations. I enjoy getting my hand dirty even if it doesn't pay much helping out a friend. I'd rather hang out in my man cave instead of relaxing in front of TV.
I own a US made Bridgeport mill, an old US made Hardinge lathe, various US made grinding equipment and some welding and brazing equipment. I like good 'old junk' best.
I may soon add a CNC control to my mill after I move to the Rockies.
My engineer buddy has a self made EDM sinker machine we built to make gun parts. It's really cool. We burned a 1/2" hole thru a hardened 1" thick tool bit in about 20 minutes, just for fun. I have access to that too. I've used it to easily burn big broken bolts out of 4wd parts.
I'm a old school hands on DIY type guy and enjoy the manual fabrication processes. I do lots of stuff like the videos here, but generally not quite as large.
I'm still building lots of 4wd stuff and high end bicycles for myself, friends and clients. I love to prototype race car and sand rail parts for some of my buddies. I still do contract small batch work and prototype work if the money is right and IF it's something challenging.
All my career, I've only done work I've enjoyed and looked forward too. If my jobs got boring or I was unhappy, I quickly moved on. Life is too short not to enjoy one's work. We spend so much time working, we'd best enjoy it. Anyways, I've never had trouble finding work. Good fabrication skills are highly in demand now.
Before I retired, I machined aerospace hardware and tiny surgical devices using lots of the more modern 3-6 axis machinery. Aircraft maintenance machining and surgical devices were the most challenging work I ever had.
The stuff we developed for a heart surgeon we often needed to manually machine looking at parts thru a microscope. I went from machining giant airliner parts to tiny complex pieces made out of titanium. It was sort of a trip, but all the machining principles remain basically the same. Seeing it and inspecting it is the real challenge.
@@garymurt9112 Actually i have no idea. I just own an old Pratt and Whitney triax tape o matic i was told was using punched cards for programming. I know it used to have a giant reel to reel tape machine to save the programs on. Since I’ve owned it, it’s been retrofit with a centroid control.
from one Old Learner to another: yes, doing is the best training; making mistakes is the very best teacher
Ive done literal hundreds if not thousands of different parts that needed to be clamped down in the machine. If I can say just one thing that will save you a ton of headache; Make sure your clearence height between every operation is higher than your tallest clamp-setup. Depending on your machine it might make the part take a little longer to finish but nobody wants to see the machine try to rapid feed a large drill sideways through a clamp.
I just stick in 200mm if i have clamps on the table. No point in puckering it.
@@spikeypineapple552 Oh nice I'm usually hovering at 150mm and yeah youre 100% right - no need to stand there and risk anything.
A colleague of mine thinks its wasting time but he has a hard time convincing anyone with the amount of broken drills, clamps and parts that goes in his chip container ^^
I am proud of you Adam!!! Progressing nicely into the previously unknown!!
I always do the high clearance plane when using strap clamps. Less drama. You need a backside chamfer tool for one and done.
Adam's talking the language, confidence is growing. I predict he will become obsessed with CNC, and become proficient with it within 6 months.
He is proving An old saying wrong can't teach an old dog new tricks lol
This is the best part of the day for me, sitting down and watching one of Adams EPIC videos! keep them up!!
working with clamps it worth having your retract to 2" in travel, peace of mind and cheaper then breaking tools
Thanks! This brings back memories of my first factory machine job in 1975 as a radial drill press operator out of high school. I had to lay out by hand bolt circles on flanges all day long. Parts for dredges at Ellicott Machine Company in Baltimore. We had one CNC machine in the whole shop and it was a test mill to see how they liked the new technology. Blue the flanges, lay out the bolt circles and holes with dividers and set it all up manually. Loved that job.
You should be proud in your continuing education journey! I'm 59 and the best part of my job is having to learn something new. 😊
Really cool to see you on the cnc again Adam. You’ve clearly learnt a lot and we’re learning from your videos too. A lot of the experienced cnc guys on TH-cam gloss over the basics so it’s really good to follow your journey.
You need to build a big 2" thick aluminum sub plate to make these jobs much easier. We had both large sub plates that covered (and protected) the entire steel table or smaller sub plates that clamped in the mill vise(s). If our parts weren't too tall, we'd bolt numerous vices , rotary tables, dividing heads or whatever's needed to the sub plate.
Now you can drill straight into the sub plate and avoid drilling into your nice 1-2-3 blocks. You can put locating pins and tapped clamp holes anywhere you want. You can keep using them job after job until they become Swiss cheese. Or you can save them as dedicated fixtures for repeat jobs. But you probably already knew all that stuff.
We kept most of our common fixture machining programs in the memory of every machine. Sub plates, vacuum plates, soft jaws, etc. We made fixtures to hold parts in pockets for the 6 work coordinates to machine all sides of a part complete or even multiples using sub programs.
Those are my favorite type of heavy duty toe clamps BTW.
You can also use those hexagonal cam actuated clamps (I can't remember what they're called) to clamp where you're not miling the periphery or ID. If we are milling periphery and ID, Id bolt thru several of the drilled holes.
So many ways to 'skin a cat' so to speak.... That's what makes machining so interesting!
Cool man. Nice info!, glad to hear a reasonable you.
I have to admit, I was stuck "old school" mode and being if I had a shop I would lean heavily with the older machines because that was all the interest I had, this episode kinda opened my eyes toward CNC machining. The clarity of your step by step movements showed me a new way of doing things. I appreciate that Adam
Instructional videos can be very helpful, but seeing someone go through the learning process while both asking and then answering the questions that are going through my head adds a unique quality to your videos. I doubt I'll ever run a CNC machine, but it's fascinating to see. I feel like I have a deeper understanding and appreciation of the process. Excellently done, as always.
Also, "pucker factor" is now in my vocabulary.
Went from pucker to relief and cut cycle time in half in one job. That's a win. Fun to watch this new chapter for Booth Machine. 👍
I love to see someone my age learning new things. Made me realise that I can still learn new things myself, that the skillset I have isn't set in stone.
Thank you for making these video's.
I haven't done any machining since the early '90s, and to me this is like a cross between technology and witchcraft. You have definitely sated my curiosity.
WOW Adam, I am so proud of you. You got it figured out buddy. I love watching your progress. Thanks for sharing
Make your clearance plane like 2 inches above the part and your rapid moves will clear and you don’t have to pucker up so much!
Yeah no reason to cut it so close
very well done Adam. I am super proud of you. It can be rather arduous for people to add different skills especially with people of you mastery of manual machining of all the differing types. I would love to buy you a beer and have a conversation about how fun this kind of learning is. I went from being a mechanical engineer with a degree to going back to college for a Computer Science Engineering degree and now working in this industry since Jan 2005. I know the butterflies in changing lol. So I applaud you and I am proud of you as well. I look forward to so very many more excellent videos from you.
Adam, when clamp position is operator dependent, ALWAYS use your 'Z' offset for tool clearance!!! The tiny increase in cycle time is well worth reducing the pucker factor.
Glad to see you thought to make those changes!! I made my comment before the end of the video.
So glad to see you use those CNC machines. I agree is you have to make a simple "one of" item manual machine is the smarter move. More pieces CNC the way to go. Always enjoy watching how you think.
Take full advantage of those rapids and increase your retract height. The extra few seconds on the job are more than worth it to not have to worry about your clamp positions 👌🏻
Yes Yes Yes
While I'm on the woodworking side of cnc, the one thing all cnc work has in common
A cnc machine does EXACTLY what you tell it to, not what you intended it to do. Success happens when intention matches up with the gcode.
I can make that even more generic: any computer code does exactly what you told it to, not what you want. What's why we software developers always have to deal with bugs in the code -- no matter how hard you try, there's always cases where code and intention don't match up, and so so many of them happen in pieces of code you didn't think could be wrong!
When I worked for Kawasaki motors in Maryville MO I would use fan tips on the coolant lines. Run them vertical then they cover a wide variety of drill lengths.
As a software tester, I love to see manual expertise being applied to automation. Best of both worlds and I see it expanding your skills.
Excellent work!!!
Very well said!
It's really fun to watch a CNC mill tapping holes. It precisely feeds the tap with a servo, using software to match the tool's movement speed with the threads density, instead of using a free-floating quill, as a manual mill or drill press would when you need to tap something, right? I know there's no magic behind this tool control, but it feels like magic anyway.
If this looks like magic search for speedio drill and tap then your mind will be blown
It’s fun to go along with you on this ride. Gaining confidence in the process and learning it. You are definitely improving, great work
Just raise the clearance height to clear the tallest clamp.
Adam, I'm proud of you. In the past I have criticized you for sticking with what you know and not being willing to change your ways. Well, I take that all back. You're really trying to learn your new machines now and that's a good thing.
23:28 i like to do the chamfer before the thread because the tool will create a burr on the thread and also the chamfer will center the tap if its in a floating tool holder.
Everyone chamfers before tapping. It is so obvious that I don't even think it is taught. How has this passed him by for so long. Just swap over the last 2 tools. Better still, use a large spot drill at the start to cut all the chamfers before drilling & lose the last chamfering op. These are not CNC tips, it's established machine shop practice.
If you want to reduce the pucker factor, you can set your retract height in between holes above your clamps. That way if you have your clamps slightly off in between parts you won’t clip it on a linking move.
Even slow machines are so fast that it only adds a few seconds the the cycle on each part.
Right on. We got that changed for the later runs so it wasn't an issue.
@@MechanicalAdvantage Oh ffs. That’s what I get for commenting before the end of the video. Love your fusion 360 tutorials by the way. They’re super well done.
@@kevind1865 Thank you. Once we got that height changed when he told me about the issue, then he could let things run at full song without worrying about hitting the clamps.
"You've come a long way pilgrim."
Very great learning experience for someone like me who used to deliver those machines all over the country but was never to see them in the real world being used.
ABOM so happy for an hour of content. Loved every minute. That meal is awesome. I love the color too. You are encouraging me to get one.😅 can’t wait for the next lesson learned😮
I understand you were wanting to work more with Fusion 360 but I will say the conversational programming in the Milltronics makes this kind of work super fast and easy. You could have made the clearance and depth changes at the control in about 30 seconds. Great job as always.
I love to see an old dog learn new tricks
Adam, I loved every minute of this! This is the first video I've seen that made me think you're going to be a CNC machinist! I have no right to be proud of you, but, damn, man! Well done.
Love the Pucker Factor...I see workers running at warp speed and can feel the floor vibrating at touch...as a manual guy...I don't even like walking by. Practical Machinist has a great segment on Manual vs. CNC...when things go wrong on the CNC... it's lighting quick. Tool movement...huge pucker factor. The experts count spindle drops and table movement time...I still use a chuck key in my tool changer hand....GREAT JOB Adam!!!
you could have changed the pattern for clearance too. instead of going around the part, use a star pattern.
thx for this 🏅 .... a very profound & very detailed explanation for a noob like me 👏🏻
so cool to see that carbide. Been watching for what seems like a decade, amazing to see how far you have come. Thanks for all the content
Great job Adam.
set the default tool retract on all tools to 2" or buy yourself some rubber underpants, also consider chamfering all holes before tapping, Great show
It's always good practice to set your travels height ABOVE the height of any fixtures when your fixtures aren't permanent / measured & modeled into the cad/cam package before creating tool paths. This will allow you to run at full speed without worrying about crashing into fixtures. Yes, you lost a little bit of time on travels due to the extra height, but you end up saving time and worry because you don't have to babysit the overrides or slow things down "to be safe"
When we programmed this part, he had an idea of how he was going to set these parts up, but nothing was concrete. Spending the time to place the 123 blocks and clamps etc. in this setup is overkill when you could just get it setup and then measure how high the tallest clamp is and not worry about the clamps at all. Especially when he has a reference part that we can use to make sure he doesn't put a clamp where a toolpath needs to go.
Good learning experience,Adam.Thank you.
Im gonna save this to watch at work tonight yep
You are getting there Adam , a great job 👍🍺🍺🥇
Great job. Thank you 😊
Commenting to support the channel
Very nice. Getting better each time.
And that's how its done, sweet!
Excellent work !!
Just a suggestion, In drilling cycle, you should use G98 instead of G97 that way, tools always clear the clamps by your chosen height in line before the canned cycle. Ie. G0 Z3.0;
G98 G73 Z-.5 R.2 Q.05 F3.0
Hello Adam.I think you made right choice purchasing milltronics vmc and lathe.Milltronics are underestimated but very nice machines,I used to have Rh20 mill and love it.Simple,reliable,easy to use.Nice job by the way😊
Great job!
Very cool Adam, really appreciate your honest as you go through your learning with CNC/Fusion360.
Good stuff
Nice Adam, I'm glad you're having fun :)
It's pretty exciting to watch you learn.
I’ve been watching you since about 2017. It’s so cool to see what you have been able to build during your career. Congratulations, and I’m sure your success will continue for a long time.
In the future, it is helpful to set your Z clearance to move well above the clamp and then rapid down to .200 above surface then go to machining speeds you will breathe a lot easier
If you watch farther, this is exactly what he does in the second iteration of the program!
Great job Adam
Thanks for the show Adam 🍻 🇦🇺
Thank you for another great video. Cheers
Love the CNC content. Hope you don't have any crazy screw ups like me when I was learning on a HAAS and end up running the head into the material/work holding.
Almost had one of those moments at 16:55 nearly running into the clamp. Those times get nerve wracking 🤣
Love this video. ❤. Well done
Proud of you buddy. You have made great strides in your CDC machining journey.
I watch with great attention and curiosity Adam... thanks for sharing your journey...
Very nicely done Adam. Great job 👍
Ridgid tapping is so COOL!
Next lesson is Thread Milling 😮
It's interesting that some folks asked to see the 3d animation rather than or at least in addition to the actual machining process. I don't think it's an age thing either, I'm 63, retired and enjoy watching both myself!
Aw the ol pucker factor 😂 solid content
Love it.
Very good job.
Really nice videography and editing on this. The in-picture overlays (e.g., why the shrink fit tool holder beat the collet) were great for explanation!
CNC still looks like magic to me. Very cool tools you have there.
very cool!
nice job Adam
Another A+....nice job explaining the why/how of this process and I liked the video work getting in both the computer screen and the actual work piece. Makes it a lot easier to understand what's happening. Great work!
Nice job 👍
❤❤ Your definitely learning how to run a CNC MACHINE.
PARTS LOOK GREAT AND MADE FAST.
Such a bad ass program. Nice work sir.
Having grown up in the manual world I would think you can appreciate the value of CNC for production work. I’ve enjoyed your journey. Those rapids make me cringe too….😅
Yep. Those flanges are a perfect example of a slow and tedious part to run on a manual mill, but fast and effortless on a CNC. An order for 30 more would take only a little longer than the 5 or 6 he machined.
I'm a little goofy about one thing I love hearing you talk in time lapse it sounds really neat to me.makes me chuckle.
I agree with you. Using the Cad/CAM approach will make you a more well rounded. Which I think you want to be. When I had time I even modeled and my clamping tools and hardware and brought them in my Inventor models.
Nice job man!
Hi, as a beginner home machinist. I have never seen any kind of CNC programs, I think this is fascinating, this is such a time saver if you're making more than one piece.
God bless you 🙏 abom79
So far as the CNC goes, this vid was the most interesting for me.
Set your clearance higher in the CAM software.
I love watching you do CNC work. Makes me think of my CNC machine, which is only a flatbed router, but it works in a very similar way I'm using fusion 360 to drive it too
No critique from me. I am so proud of your advancements in tech and making it work. Keep on charging Bro!
Based on the chips, you can increase your feed rate a good bit. Also you can use a deeper peck, if I want to be really safe I'll use half the diameter of the drill, but realistically you can go much deeper. With the carbide drills, they are designed to take straight shots, you don't need to peck. Great job for where you are at in your learning process.
on these thin plates i would just drill through without pecking but then also using a carbide drill
@@ipadize I've seen it be a nerve wracking experience for folks to shift from a manual of bed mill with a quill to full CNC. One of the hardest lessons to learn is an emotional one more than a technique one, and that is that it is often safer to push harder and faster (within reason) than it is to try and be gentle. He seems to be doing all right though and he'll get there. I agree with you about going straight through, it's pretty much always better where you can.
CNC is the future and the youth today learning CNC will be setup for success later. Removing as much human error from manufacturing is one of the goals. It's fantastic that you're stepping into the CNC world and learning more about it. I've seen lots of comments here about how people want to just see everything done by hand, and you do a great mix of both. CNC will replace manual machines in the future, it's just a matter of time :)
A horse and buggy was great technology at one point as well, but we've advanced and moved on from that.
CNC has been around for a long time though, it's not some super new thing.. They've been around since the 90s, it's more than industry standard now. Machining has been shedding a lot of young people (in my area at least) due to poor wages, poor environments, and insane work load... You have to fight tooth and claw after many years to get paid what a software engineer gets paid starting out, if you want an idea of how terrible wages are (generally), some places are better than others and do pay fairly but they're a rarity... Then you also have to deal with routine lay offs because it's feast or famine in this industry. Don't get me wrong it can give you an OK to mostly comfortable living depending where you live, but it's definitely not attracting boat loads of young guys.
We're competing with developing countries that are running CNCs and paying guys a couple dollars a day. A machine is a machine, the product is more or less the same. It's automation.
i think you are doing well with the cnc and thanks for the video.
Ecellent work Adam. Very good .I like . All good for you.👍👍👍👍👍👍👍👍👍👍
Personally I would have chamfered the holes before taping the taped holes so there would not be a burr there.
In the era of cnc, we worry more about crashing the machine than the work itself 😀I remember my first time crashing a carbide tool into the vise and a parallel...
What a great job to enhance your CAD/CAM skills.....FYI- you can use the G30 command as a second stop position, so the table comes to the front center of the opening after the last operation, just make sure when you set up the G30 that it slaves your Z axis to home first before it makes the final move in X and Y.
