V-Block Adaptors for the Flex CNC
ฝัง
- เผยแพร่เมื่อ 24 พ.ค. 2024
- I'm using the Flex CNC to machine some adaptor plates for a pair of large v-blocks that will be used on the Flex machine bed to hold large rounds. . Along the way I run into a couple issues due to my continued learning phases of running this machine. In the end I believe I have two good parts that I can use on the machine for some upcoming jobs. #abom79 #cncmachining #flexcnc

I hope this isn't taken poorly. Although I appreciate all the work and effort it takes to make these vids for us.
I really do miss the home shop projects. Not just because of the location. Just the style of content. It was machining. Almost like a couple friends working on a project, or more like one friend teaching another how to do things. If that makes sense?
These type of vids are more like Infomercials, for lack of a better term. I can appreciate them, but have a hard time getting "into" them, or getting excited about them.
I dunno, it's hard to explain.
Anyway, I thank you Adam for your time and effort. As well as for reading this, if you happen to. But if you do, PLEASE don't take it negativity!!! It's just my opinion, which means nothing in the grand scheme of things.
Y'all be safe out there!!
Me too, but I think Adam has to now produce a blend of videos due to his chosen set-up.
I'm not a machinist but I love your videos. I've done some coding in my time and really struggled with updates and new processes. I have a lot of admiration for your attitude towards learning and sharing new things.
Another things is that you shouldn’t be worried about cycle time because you’re not running big production, be more conservative with the feed and speed and tool life. 💪🏼 love your channel.
I'm glad you have a new shop full of of fancy new machines. Unfortunately I'm old school and I would prefer watching paint dry.
I agree.Paint drying would be more exciting than this.
Your desire to want to learn more advanced machining technologies is admirable. Thank you for your content. I love your channel!
Thanks for taking us along on your journey of learning cnc. Something I'll never do but fascinated to learn about.
Hi Adam thank you for sharing your work , I know nothing of cnc - looks complicated .
I’m amazed at how many of the viewers are complaining about the videos it’s incredible . You know if they don’t like it just don’t watch it , no need to be rude . Hey I just started watching your channel and as a self taught hillbilly at machining appreciate what you teach .
You are very talented and precise . Thanks for sharing whatever you do . All the best from New Zealand
Adam always leaves me better taught after a video, and I can help my welder/fabricator son without messing up.
Be sure to give the people that are coming in for the demo a link to this video (and links to all your FlexCNC videos.) From all that they should get a pretty good understanding of much of what is involved in getting one of these machines and how it will be delivered and setup. Great video Adam, as always.
I really enjoy watching your CNC content as much as your manual machining content. It's really cool to see you learn, make really natural mistakes and share how easy it is to get things wrong even as someone with years of experience. Lot's of respect to you Adam. It will be great to see what you accomplish in the years to come.
Thank you for showing us this Adam. Appreciate seeing your journey.
I understand why Adam embarked on the journey with the new shop. He’s a content creator and not really a working machinist anymore. So he probably felt it would be very entertaining to watch his development using more automated machines. Thing is I much prefer watching him showing off his expertise in manual machining vs stumbling through learning how to use all this automated equipment that collects dust most of the time. I hope he can inject some more interesting content into the channel. 20+ episodes to finish machining a bench top vise vs CEE rebuilding a crane in their series not much of a comparison.
I question your conclusions. If Abom was mainly interested in content, I think he'd be running the shaper more (Yes, I'm a shaper addict ;) I think he started with the CNC machining because he is interested in it as a machinist - at least as far as keeping up with the competition. It's hard to recognize when you need to upgrade skills and technology, and I feel like Adam is doing that and sharing the journey with us
@@kumoyuki So, would he have gone out and bought a new CNC machine or even an used one, had them deals not materialised, where he probably got them loaned for zilch,' to use as he pleases', only then to be returned at some future date.? And who exactly is his ' competition' ?, as post his time at Motion nearly all his paying jobs were for initially family and friends, then viewers and more recently his friend and landlord with his fabrication business. What he's concentrated on is growing his channel, which became a big success and that was where the money was. Even recession proof! , as he is very aware that the recession of the late 2000's killed off his dad's job shop and also any willingness to keep on going once the recovery set in. More recently, what he's concentrated on growing is his Adventures channel. He said it took him 10 years to get to be a plateaued highly skilled manual machinist; probably when the was about 30 and around 2010, the start of the upturn. Normally, that would have been a good time to extend one's horizons into the CNC, maybe by switching firms.
Naw, he shows us what he is learning. Sorry you don't enjoy it; I do.
Keep it up Adam, watching you grow is a huge inspiration ❤
it may be worth attaching a gopro mount to the wall behind the CNC looking down the bed. it would probably make some nice B role.
"The machine turned itself off..." But that doesn't explain the crash.
There are two types of CNC professionals, those that have crashed their CNC system, and liars. Welcome to becoming a Professional.
During the years that I worked in the CNC industry, I never did come across any self proclaimed 'liars' as you put it; but neither did I know any habitual machine crashers who still kept their job.
@@james-ew7kl So you just had to say that?
I mean those things can happen ?
@@Shamefulbird I never make the same mistake twice. I make them four or five times, just to be sure.
@@kevinreardon2558 yeah same
I freely admit that I probably have no clue what I am talking about but if the CNC mill comes to a halt and crashes because someone got in the way of the laser safety detectors then why on earth doesn't the programme default to (say) withdraw the tool by 100 thou from the workpiece and then go all stop?
Great video Adam!!! I started watching you old home shop videos likes 6 years ago, amazing knowledge aquired all this time!
You can work first on the top side flattening all the piece, then do all the machining on the backside, and finally the machining on the top again. It's an extra step, but you can ensure both flat and shiny surfaces.
Adam, suggestion for FlexCNC; before the machine does anything when tripped; only retract the spindle fully; then continue the emergency stop.
"The plate was bent"
I'm guessing FL finally got hot enough that it stress relieved the steel. 😂
Adam, you're meant to be the guy with BIG CUTS. That end mill should be running at double that feed.
Make one channel for manual maching and one for cnc. Manual is what i am always trying to inprove on.
Great job, Adam! Just keep doing what you're doing and everything will turn out nicely over the long run.
I find the cnc interesting but I do miss the handwork
Thanks for that cool demo on the Big'un!
I get that the safety scanner shut the machine off, but why did it crash and not just e-stop?
It stopped fine on the e-stop. The crash happened when he attempted to reload and restart the program from within the program instead of starting over
@@MechanicalAdvantage Is it possible to single block the first few lines and then jump to the bit of the program before the crash?
Cool video, fascinating stuff. I like the new camera placement as well.
Chào bạn. Tôi đến từ Việt Nam. Tôi đã xem bạn rất lâu. Từ lúc bạn chưa mở cửa hàng mới. Giờ bạn đã có nhiều máy cnc mới. Nhưng tôi vẫn thích bạn làm việc với những chiếc máy lúc trước. Thật tuyệt vời.
❤ When you are reaming a part for die making the dowel pins are a tight fit and you use a hammer to put them in the hole.
You never want a pin to just push into the hole by hand.
The die will fail in a very short time if any section has the slightest bit of movement when a 50 ton press hits.
Great work,Adam.Thank you.
Great video Adam. Love the cnc content. Thanks.
I'm pretty sure that the jumpiness that you are talking about at 22:30 can be improved by using the smoothing function in Fusion 360. The problem is, that the adaptive toolpath without smoothing uses too much small lines of code for the CNC machine's controller to process in time. NYC CNC has a video on this, where John Saunders goes way more into detail and does a way better job explaining it. It is Fusion Friday 128 (FF128) on YT.
Keep up the good work and don't get frustrated by the guys hating everything that is "new" and which they don't understand.
Adam, Those laser systems like on the gantry protecting the front of the machine are programmable and generally have aux outputs for both the warning and the e-stop. You might ask if there is a way you could add an audible alarm (like a vehicle backup alarm) to for the orange warning area. I would ask your contacts if this can be added or which terminals in the control box are for these aux outputs. It would give a warning if your leg or something else entered the warning area for some reason and when you got out of the warning area, the audible alarm would silence. I have worked at 6 different manufacturers and all had these exact laser setups on everything from Amada turret presses to moving robotic tuggers traveling through production areas. If someone randomly steps in front of, or something blocks the path of the equipment being protected, the orange zone will sound an alarm and/or stop (the robotic tuggers) for a short period of time. If the person or object comes into the red zone at any time during operation, it will e-stop the equipment until maintenance or the equipment operator can reset the machine and/or properly restart it on the tool path.
I didn't pay real close attention to the Art teacher in school, but you Sir are an artist (sans the goofy beard and silly name!) Thanks for reminding me to learn something each episode in the shop. And thanks for the video!
I always chamfer before tapping and reaming.
Me too. That way it doesn't create a burr on the start of the thread.
remember when this channel used to show machining... now we're watching 1 video a month about some random shop tour, or in this case, 10 min's into a video before any machining happens...
You live, and you learn.
That was very interesting, thank you Adam
The good old days of chewed up face mills lol
Thanks Adam.
Just a suggestion, if you ever want to learn this stuff, make an arrangement with another cnc shop: they run their parts on your machines & you follow along as an apprentice for a year or 2? Someone would be wetting themself to get on the capability of that flex machine
I love the way you organize your videos, well thought out in step by step order. I just saw the crash when the machine stopped when motion in that area was triggered. That was not your fault. As an engineer, I think the machine stop Event (Red Light) should have added a Z movement up so the cutter stops clear of workpiece, BEFORE shutting down the cutter. I'm sure this could be a program change. Shame on Flex CNC!
but why does breaking the beam crash the machine? shouldn't it just stop?
Incorrectly coded or otherwise poorly implemented emergency stop? In my opinion, light curtains should not even stop the machine, but only put feeds on pause and continue when the obstacle leaves in front of the light curtain.
@@peto22 Feed hold+spindle off after 0.2 seconds would be my prefered method. It HAS to kill the spindle.
If any of my cnc machines stops mid operation I have the option to either start from the point it stopped or return to start of program. They will never start ahead of the point they stopped unless I was to advance the restart point. I can only assume this was an operator error and nothing to do with the safety stop system.
If you edit your post to spit out "N" style sequence numbers you can start from N2, N5, N26, Aslong as it calls up the tool and work offset in the beginning lines of the sequence. Hope this helps
Should do op1 in the vice and op2 bolted in place on the table. This will remove variance in vice hold and give you a better shot at parallelism.
Hey @Abom79 I wonder if you could set up the flexible air blower over the lense of your GoPro when in the machine? Would keep the coolant off the lense. Great video!
Very nice work sir
Great show Adam, wouldn’t mind some Monarch or Pacemaker every now and then, still I find it quite interesting with the progression with the CNC machining. Looking forward to see some challenging projects coming up.
All the best
You can get the insert seat welded and remachined. Your tool rep should be able to make that happen.
I'm assuming that's 1018 crs(nvm see the flame edge. Thats HRS)? I personally shoot for
.0002-.0007 for press fits. I used to indicate all reamers in at the cutting edge at the lead in. I'd tap the reamer in with brass at the collet junction. A true running reamer will still blow a hole out if it catches a chip. Use a .4375 or .375 4 flute emill. Relieve the cutting edge back will a surface grinder and 5c. Leave about .1 cutting edge, then helix bore. If you do ream, i never run a reamer fastet than 1500rpm(won't blow top of hole out).
Use a diamond pin in place of 1 dowel if using 2. It'll aid in removal in the future. If you don't have diamond pins, put a couple of knock out holes in the sub plate.
If you want a good finish with a shoulder/face mill, remove every other insert, or just leave one. The "scallops" are the miss match of insert height.
If thats an AlTiN coated emill, ditch that M8.
Last thing, that shoulder mill is to large of diameter for that spindle taper. Use the same milling technique to rough as you did to finish. That sfm is for HEM but you Ae is to large to engage RCT successfully.
That's a bummer that controll did that "non sense" after essentialy tripping the e stop. Keep up the content. Appreciate ya
Sure you could shim the V blocks to align them, but I think a better way would be to skim the faces of the v with a 45° cutter once they are fully assembled.
you can put a 3/8 tapped hole lined up with t-slot to use as jack screw to get plates off without prying up.
There is no circumstance where tripping a safety interlock (the Sick laser) should cause a machine crash. That is utterly insane and Flex needs to fix that. I'm guessing they just shut power to all the servos and unlock them, so the momentum from the face mill still spinning pulled it across the work like that. A proper shutdown has the machine very rapidly halt before cutting power to the servos for this very reason.
EDITED TO ADD: On an IG video, Adam notes the machine simply stopped. It was (as others noted below) a bad program restart line selection that actually caused the damage.
He restarted the program incorrectly
@@CHEWITT-wq1zd How do you figure? He says nothing about restarting the program to cause the crash. All he says is that the machine shut down after he tripped the Sick sensor.
@@LumaLabs It's just faith that no company would ever do that, and it doesn't really make sense. If the facemill was freerunning, it wouldn't have made it all the way over there, and it definitely wouldn't have enough enertia to kill those pockets like that.
The only way I can see this is if like the other person said, if it wasnt reset and homed before restarting.
@@LumaLabs he said it on his Instagram page
@@johanneskienle362 Ahh... yup. There it is. Sort of a big missing piece of information to not put in the TH-cam video, because otherwise - the alternative explanation of how a safety trip leads to *that* damage is really really bad.
Speaking as a guy with lots of schooling, you must have a really flexible, greedy mind to learn so much, so quickly. That's impressive, and it must be fun for you.
Adam, if all you did was ‘ruin’ a cutter, you aren’t doing too bad!
Where I worked one of the guys put an incorrect rapid offset, + instead of - or vice versa, practically totalled a week old Bridgeport CNC lathe, tore the tailstock off, busted the tool carousel and the cross slide, it was so bad that it had to go back to Bridgeport for reworking, it was beyond on site repair!
There are basically two groups of CNC operators, those that have crashed a tool and those that are going to crash a tool!
Don’t beat yourself up over this!
there is an old saying, attributed to many different people, " He who does not make mistakes, usually does not make much of anything"
For young folk starting out in the CNC production world, an alternative philosophy might be more fitting. Something along the lines of 'High output , no scrap and no crashes ( or very few, at least) and you'll go far; or at least get to see your next paycheck'.
@@james-ew7kl That is true with enough expereince and you are only running true and tested production runs.
As soon as you start to develop the programs you run, sooner or later failures are inevitable. Of course with growing experience those failures get smaller and likely cause less damage.
Otherwise, especially when learning something new is involved, I know a different variant. There are two kind of machinists that never crashed. Those who lie and those who never actually tried.
Thanks, Adam! 👍
CNC is old testament computing, lots of rules and NO mercy. scrapped a coffee can size lump of bronze over 1 missed detail in post, 1 lead vs 2 lead acme. Okuma is a great machine, but holy hell is it trying to crash on you. For the drills check out Dormer ADX series drills they are remarkable for a hss drill, no pecking, crazy feed and they last. we are currently running a 1" deep #7 (5.1 or 5.2mm) for a 1/4-20 hole in 1018, no issues at all. we run other sizes too, never need to bother with a spot drill even on an 11/16, things just eat.
focus on safety heights rather than optimizing .. you can't run high-speed milling on that machine .. no matter what the person who sold the machine says, It's good for long pipes and holes and small milling. it's not a Mazak,,Heller,, okuma machine..
Just to be clear, the following statements are observations and not meant as criticism.
I respect that you're still learning CNC and that these parts are demo pieces, so I mean no offense when I say that this demonstration wouldn't give me confidence in buying a Flex. The safety features alone would make me cautious, knowing that simply standing in the wrong spot for too long could cause a crash, assuming that's what happened. Without knowing the exact events that led up to the crash after the emergency stop, we can only guess the cause.
From what I see, the machine isn't handling high-speed machining well, which might be causing the stuttering. I've seen similar issues with Haas machines when high-speed machining isn't enabled, so it seems like the controller can't keep up with the adaptive strategies. Another possible cause could be that the lead-in, lead-out, or plunge feed rates are too low in Fusion.
The Flex seems designed for very specific applications and might be overkill for these parts. These and similar parts would probably be best made on your Milltronics mill if you're focused on optimization, while the Flex might be better for larger parts that take advantage of its size. Those tool change times alone can undermine any programming optimizations.
Regarding what happened at the 19:34 mark, I'm not entirely sure, but it looks like your part was shifted too far to the left from where the WCS was originally set, considering how deep the cut was on that end and how light it was on the opposing end. For parallelism, you could bolt the plates to the rails and then face them to ensure they're parallel with your spindle and both parts are of equal height.
Anyway, keep at it! We all started somewhere!
Great job. Thank you 😊
Failures do happen. But the real failure is if you dont learn and adjust from it 😊👍
Making fails is a part of this job. There is so many factors to pay attention to. Especially when using new tools and machines 😊👍
It seems like it’s the lead in and lead out that you need to adjust in Fusion360.
When the machine shuts off like that it should stop the spindle and retract it to the up possession.
If you retract the spindle you risk either further injuring a person inside the machine or destroying something if you were doing a back-cutting or slotting operation, not a good idea.
@@skwerlz
Now what is the idea of doing what it did? Going out in an angle through the material?
@@Drottninggatan2017 not agreeing with what it did either, it should either be a hard e-stop or a .05s dwell to preserve tools/work into hard e-stop.
You don’t know what you don’t know. Now you know.
Yet another incredible video Adam, these are so good!
Some nice big rads on the corners would be nice. I would prefer to add 4 keys in slots instead of milling all that material away. That would help with the inevitable twisting. The vee blocks are really tall, do they really need to come to a corner for large diameter shafts.
Hey i have a little improvement for you to make: i would shrink fit the carbide drill because as you can see in the vid a lot of coolant that should go through the drill doesnt and because of that the drill has a higher risk of breaking. I would immeadiately change that because having a carbide drill not shrik fitter is a no go
Another great video!
Maybe see if you can timeshare the flex CNC with the people coming in wanting to buy one local. Maybe a good additional source of income for you
Wondering why you have such large CNC machines - typically used for production or large CNC milling jobs? Are you leasing out time on the equipment when you aren't using them? Just seems like an enormous and advanced machine to learn on.
I don't know, but Adam and his ancestors have often worked on rebuilding or repairing large rollers and hydraulic cylinders for local factories. A company with a shut-down production line is a company losing a lot of money fast.
@stuartschaffner9744 non of the cncs he has would be a good fit for that kind of work
@@keithhasafastcar , OK. Would you like to explain why? I notice that Adam has often worked on production-line parts that need to be replaced or repaired because of wear. Often the part itself is complex and valuable. If the part is no longer manufactured then it can be extremely valuable. CNC machines seem to be able to handle high-precision machining on high-value parts with complex geometries.
I'm not saying that you're wrong, but I think that we would all benefit from some more detail. I'm here to learn.
@stuartschaffner9744 simply due to size and rigidity. The two miltronics are too small to efficiently do work the size of what he used to do and the flex while being a larger machine that could accommodate the size of the parts being a 40 taper machine the spindle would lack the power and rigidity to run larger tools and program them at efficient speeds and feeds. As well, because a lot of repair work is irregular due to wear and damage it would be time consuming to model them in a cad cam accurately unless you had a 3d parts scanner which is why to this day the majority of repair work is done on manual machines
@@keithhasafastcar , very well argued, Keith. I might quibble about the need to accurately model all of a worn part in cad cam. I have done work in computer graphics where we used to use virtual bounding surfaces to establish where the operations should be limited to. Kind of like guard rails. I wish the best for Adam for being a pioneer.
Interesting.
G'day Adam. Always liked your flex CNC. One you get a few more jobs to do, it should work well with you.
When you do the full demo to the New Buyer, can you do a Complete Video, will go down great, + Abby will have tons of Fun Filming everything 😊😅
Wow 1200sfm on that facemill in steel seems a little high, surprised they recommended that high. And the "jumpiness" you see is because there's too many lines of code and the controller can't read it fast enough, try turning up the smoothing and increasing the tolerance to help with that. Also seems very dangerous to have all the retracts set so low when you aren't facing off the highest part of the stock, raising that could avoid any future accidents
This is certainly true with older machines, but I'd be shocked if this newer machine can't handle modern toolpaths. If it can't, I'd be incredibly disappointed as there's really no excuse with the technology we have today. Perhaps there is a "high speed" option that needs to be enabled in the controller to read that code properly? The flex CNC guys aught to get this sorted for Adam.
@@GetBlitzified you'd be surprised, we have 2018 robo drills that read code slower than our 1994 Matsuura does in their standard mode and it's 10X worse than his flex. But yes usually there is a roughing or high smoothing mode in the controller to fix it
@@GetBlitzified Very, very standard for a machine to bog down on a non-smoothed toolpath. I can't imagine they're selling this machine, which is basically designed to basically drill lengths of rail and stuff like that, with AICC2 or 200block lookahead. It's just not what the machine is meant to do.
You wouldn't buy a ford f150 and be disapointed it doesn't have KERS from Formula 1, and you wouldn't buy a Corvette and be disappointed it doesn't come with a towbar.
@@spikeypineapple552 I'm sorry, but on their website it literally sates "Capable of high-speed drilling, and MILLING". In their promo videos they have videos of roughing tool paths. The machine should most certainly be able to do some basic 2d adaptive paths, this isn't trivial this day and age.
If a $200 chinese controller I buy off amazon can handle adaptive paths better than a $100k+ machine tool, I'd be pissed. How can there be an excuse for that? Granted, I'm willing to bet there is a "high speed" option that needs to be enabled, in which case great!
@@GetBlitzifiedtheres a massive difference between 0.001 smoothing and no smoothing. Your 200$ controller doesnt have the same requirements as this machine does.
Good to see you showing your “Flexibility”.
a strap clamp at the handle end of those vices might make things more rigid. also ive never seen so much crying in the comments, i just dont get it. this is just learning that everone goes through.
Hi Adam,
Why didn't you start by grinding the underside?
This might have resulted in a better finish for the second piece.
Xris
you might also want to enable "cut both ways" on the face operations, you are loosing time on those retracts and rapids, its under passes and directions.
I was thinking the same thing.
I would suggest to install t slot table on one side of the cnc so you can mill bigger plates instead of this style of fixture of the machine
Flex(ible) for real!
great video. When your mill was stopping it almost looked like there was G4 command inserted there. or do you think it was the feed rate that was slowed to insanely slow?
I'm sure I'm missing something. Shouldn't the blanks be machined to dimension, square, flat and parallel before running the programme? Then you can make as many items as you want consistently.
what are you talking about? So based on your comment you should "pre machine" your stock so you can machine it? what?
He is milling the sides and the top as well as all the holes in the first operation, the 2nd one he just decks the plate to size.
So just given the 1st operation, he is making it to dimension, making it square, flat, and parallel to the underside (as much as possible, with a "flat bar stock" with a bend in it)
To answer your question without all of the unnecessary sarcasm, your head is in the right place. However, he is squaring the stock as part of the program. In Op 1, he squares the bottom and the sides to each other. Then, when he re-clamps the part for OP 2 and decks the other side, it is also being squared to the already machined surfaces. You would do this in manual operations as well. I think a lot folks see those, "squaring stock" videos and probably think that squaring the stock is it's own special operation, when in fact it's normally considered and included in the order of ops.
You're right, you're missing something.
Yeah you only do the restart crash once....then you realize it's not worth it lol....I only ever restart from a tool change.....makes it easy to find a restart point as well, and you know exactly what's going to happen....even if it wastes a little time cutting air....
22:38 : It seems aggressive when the facemill engage with the material, I’m a programmer i use Mastercam and i can control that engagement but i’m not aware if fusion allowed you to do that.
Adam, Great video on the Flex. I want to preface my question here by saying I am not a CNC guy, "back in the day" I ran manual machines ( mills, lathes, Bullard, Horz. boring mills, ) @ 40.20 you begin the chamfer on one end of the part and then go to the opposite end and then move around the part. Wouldn't it be better to begin on one hole and then progress in either a Clockwise or Counterclockwise direction rather than moving from one end to the other and then progressing ?
Don't use coolant on your facemill when roughing. And for your carbide drillbits with inner coolant, there exist closed ER collets (otherwise, all the coolant pressure goes through the open collet if you have to drill deep enough).
I’m yet to see how CNC is better! At least for you.
Red, Orange and Green? For me, I might not be able to tell the difference, as I'm color blind.
i think you were a little slow at 19:50 in feed rate
I always buy plate at least .063 up to .125 thicker than I need just for the problem you had. You never know what defects ended up in it at the foundry or what deformations happened in storage. Looks like yours may very well have been the bottom plate in a stack that sat for a long time.
the machine stopping is fine (although annoying) but it really should not crash!!! there must be something quite wrong in my opinion. it should stop and hold its position at least until the spindle stopped to prevent big facemill chew itslef into the material and destroy itself (best case) or the spindle (worst case)
now, im wondering, if the CNC industry could add in a type of camera feedback system that could visually observe the work area and the work piece, and use some sort of program that can recognize when a crash may happen or if anything like the slipping of a tool is occurring and it could automatically stop the machine before damage occurred. also, as perhaps a means to quantify the location of parts without using or in conjunction to a probe tool, and at the same time use some sort of automatic laser scan technique to help in the precision aspect. anyways, just a thought.
Technically that is feasible. and especially when it comes to tool positioning or tool slipping I heard of something like that. And that was more like holding and spinning the tool in front of a camera every now and then.
The problem is, systems today can very well compare with a known "standard". but with allways changing setups and workpieces, AI or not, systems are not yet there to capture everything or reliably enough learn the boundaries themselves.
And remember, cutting means you crash the tool into your stock material. Just at a very controlled rate.
@@alexanderkupke920 Would it be possible for the computer to think, ''OK, here's a long thin end mill and moving it this fast through a cut this deep will snap it off'' and so not do it?
@@JohnSmith-vi5pz sure something like this is possible. but as I said, there are so many things to it. recognizing the bed, the gantry, the spindle, the tool, work holding, workpiece,... of which parts can be different every time. And then you also want it to only prevent certain speed combinations, as it should not stop a normal cut, which may initially look like a crash to happen, so it better be also aware of the cut plan etc. Then there are chips and coolant going almost everywhere, so you have to deal with drops and large amounts of liquid obstructing the view, eiither because of the jets of coolant, or because everything gets blurry from a drop of coolant on the lens.
Hell of a lot of work to get it running reliably, and costly for sure. And looking at what AI systems are able to do today, I would say we are not quite there yet.
@@alexanderkupke920 Thanks, makes sense, never thought of the coolant on the lens - that would be hard to stop for sure.
How did the "safety feature" cause a crash?
I'm confused also. If it's shutting the cut off, why did it keep running the cutter and continue moving?
@@bradywilliams2666 My thought as well. Unless I missunderstand how this safety cutout works, I would expect the machine to stop everything moving, spindle and especially the gantry and just remain where it is. Not even lifting the cutter or anything, as again in this case the machine forthis function does not know what it is doing and you might be in some undercut and grab a piece and fling it around. I could only imagine such a crash to happen, if the spindle is still running and it wouldtry to go into a home position, which would not be a safe operation as the machine does not know where the obstruction causing the stop is, additionally to what I said before.
It didn't. He forgot to mention he re-started the program wrong.
Bro use the ‘simulate’ feature in fusion. Check the box that says stop on collision. Unless your post processor is producing some junky code, IDK. Fusion lets you prevent crashes pretty easily. Don’t play with Z heights when you don’t have to. Use the tools fusion gives you. Touch your tools off and get your Z and the rest is feeds and speeds mainly. Good luck no more crashes 🤞🏼
It wasn't a CAM issue. The Fusion simulation was fine. It was a result of stopping and starting the program.
Aren't straight fluted reamers hand held ones? Maybe I got his confused with spiral reamer are for interrupted cuts? 🤔🤔🤔🤔
Chucking reamers can be either straight or spiral flute. Spiral flute reamers are used for interrupted cuts as stated. Hand reamers have a long starting taper for easier alignment with the hole.
Wow first time first
No pre-ream endmill? I'm surprised...
What does the warm up do for that machine
Warm up the spindle and making sure the bearings are sufficiently lubricated, before putting them under load while cutting. Also helps with accuracy, because most of the thermal expansion/ needed compensation is done once the spindle is warmed up.
Is that Cat50 spindle??
Weirdest thing ever, flimsy sheet metal but most badass spindle taper
What is the flimsy sheetmetal? Are you talking about the machine frame?
flimsy sheetmetal like every cnc machine ever
Lots of harmonics in with that end mill while profiling. Try more Rpm.
No idea why you didn't mill in slots to be able to insert blocks to self align with the keyways on the machine... Would make it the easiest setup ever and it would have taken like 5 minutes to draw, program and cut.
Was that tool change at 100%?
