Makes me wonder how many of the programmers were true machinists, and how many of the machinists are programming. Spent most of my 40+ years as a CNC machinist doing my own programming, and I can tell you that 90% of those crashes were caused by someone having no idea what they were doing.
Or they didn’t know the correct feeds-and-speeds, didn’t have adequate work holding, or didn’t bother running a simulation of the tool path in their CAD/CAM program. 🤔
I've got 9 cncs and every one of them has a distance to go read out and a single block option and feed rate and rapid override knobs.......and I know how to use all of them very well for the reasons shown in many of these clips.
@@williamsquires3070 And that is the difference between a Machinist and a machine operator. Like you said, I would always run the computer sim first, then do a run on the machine in air. First piece run would always be single block with rapid override, and hand on the E-Stop. After that let it run and sit back and just listen.
As someone else mentioned on here, pretty much all of these are basic errors caused by people who just don’t know what they are doing. I remember many years ago, getting someone a job as a favour, he was a bit of a spoilt brat type-knew everything. I sent him on a CNC course and he started setting and operating one of our Bridgeport Interact machines under my close supervision. Despite this, one day I came into the shop and noticed he was just about to start machining having clamped a part onto the machine. The heels of the two clamps were resting on several pieces of metal offcuts of irregular shape and with burrs and sawn edges. A big pile under each clamp….When I told him in no uncertain terms that it wouldn’t do and that he should know better, he started arguing saying that it would be fine etc… I then reached over, grabbed one of the clamps and pulled smartly…. The whole lot came off the machine table - both clamps and the part he was about to machine! He just said “Oh”. I gave him such a bollocking! The balloon went up one day when he had only been there six months, when he casually remarked “well, engineering is pretty basic really”… that did it, I had had enough and fired him on the spot and kicked him out. I will show and help anyone as long as they are willing to learn, but there are too many “college bods” and “text book Charlies” in this world who think they know it all but in fact know bugger all, I don’t have time for that sort. I did a proper indentured apprenticeship 40 plus years ago and have trained many people, but I don’t put up with idiots who put their own, and other’s safety at risk and damage machinery and equipment in the process. I always tell my guys, if you are going to crash, crash gently. You have control over a machine, use those controls wisely.
What level of knowledge is required of physics mathematics programming and metal properties to get an entry job? Is it university level or just high school?
Before the days of CNC........ I worked for a Chrysler plant. One day an OD grinder , with a wheel 3 feet in diameter, decided to plunge right past the initial stop and crash full speed into a 3 inch diameter, 2 foot long gear shaft. BANG The wheel shattered One half of the steel shaft went to the operators right, and hit a beam. The other half to his left, and embedded into the power panel of the machine behind it. Shorted it out These machines were not enclosed in any way. The operator missed getting his head knocked off by inches. He was covered in bits of grinding wheel. A few cuts on exposed skin I was 50 feet away and nearly shit my pants the noise was so loud.
Scary story, any kind of machine can be a killer machine. Crashing I think is most risky downside of this profession . I had a small cut from a crashed and exploded carbide drill on my throat. I was enough lucky, otherwise it would harm my eye too.
That reminds me of an incident when I was an apprentice. This extract is from a story of my apprenticeship that I have written. "We had two big cylindrical grinders each having a wheel about 3 feet in diameter. We ground parts between centres usually with a carrier fitted on one end. I was working an identical grinder next to the one that a guy named Dudley was working on. Dudley was a much older lanky guy with a glass eye and always had a stupid grin on his face. It was unnerving, every so often there was either a bang, a crunch or a shower of sparks from Dudley's machine. I just couldn't relax working next to the bloke. One day, all of a sudden there was a massive crash! Dudley had misloaded a part so badly I don't know how it stayed in the machine, but it stayed long enough for the big grinding wheel to hit it as it came in. A chunk of grinding wheel the size of a house brick shot out of the machine and flew up in the air at a considerable speed luckily going away from me and landed with a thud on the floor. Dudley just looked at me with his glass eye and grinned. That was enough for me, I told the Forman that I was not going to work anywhere near Dudley ever again. Strangely he found this amusing but he got serious again when he realised Dudley had wrecked a very expensive grinding wheel. I Have never trusted anyone called Dudley ever since...!"🤣🤣🤣
@@montyzumazoom1337worked with a dude that was always out of it but passed drug tests somehow. Boss had him running a 6’ manual VTL which was probably the most dangerous machine in the shop. A 6’ table over 80rpm is pretty wicked. One day while boring out a part about 4’ diameter he stepped on the spinning table while looking into the bore. Luckily it was hard material so the table wasn’t spinning very fast or he would’ve died. He had stuff flying off that table all the time. I kept telling my boss to get him off that machine or someone was going to get killed and he always kinda chuckled like I was being dramatic. Luckily the dude ended up fired for some reason and the nightmare ended before something horrible happened
2:44 clearly see it just keep going. STOP you did not rapid over distance you supposed. lenght is wrong. its easy. machine has single step. feed override. screen to see how far it still go. first part is allways test. second part is full rapid if want
I think the first one with the lathe the cutting depth seems to be alright, the feedrate was a bit aggressive but okay. But as soon as the tool cuts into the work on its second pass the whole thing wobbles out of control. It was most likely caused by improper chucking force, the work was too loose.
The other main culprit was the big plunge in the middle, significantly reducing it's stiffness. You should never do a cut like that until done with the rest of the machining, as you are just turning that rod into a wobbly joint right there.
You can go block by block and take it easy on the 1st piece. Some of these feed rates are crazy. Somebody trying to be a hotdog. You can go nuts on the 3rd piece after you get all the wrinkles out. Feel sorry for the machines.
I am glad that our 5 axis CNCs in wood factory have such a mssive 20 kW spindle that it can handle even more serious accidents, you mostly just screw axis which can be fixed, I can't imagine having some of these little CNCs which have spindle like some driller from Lidl.
I can see why my teacher recommends a few years working on a mill and lathe before ever trying to program my own parts for them. 😅Some things you just got to learn from experience.
Ouch! And here I’m gathering resources to boost my skills. Talk about incentive to check all the variables possible at the desk! I’ve had 20+ years CNC turn with sprinkle of big boring mills & a short intro on a VF-4 with bad tooling support for vice fixtures. And older work. That link looks interesting for the computer I ordered. A refurbished “gamer” beast that has overkill specs for studying mill programming. And see if I can twiddle this stuff from my old long hand work. I can JUST imagine the guys who taught me turning about ready to smack whoever set up the lathes in that vid.
That is cool, milling generally considered harder than turning. From my experience I think setting tools on the CNC lathe takes longer than setting milling tools, in contrast CNC milling operations requires perfect machining strategy and advanced part holding techniques. Also does not matter turning or milling multi axis programming makes things harder I think :)
@@mechutopia9368 I agree on your points. Just imagine linking a c axis to x axis on a Fanuc control for cutting flats on a lathe. Without a Y ball screw. Ends up with extra clearance rapids and really strange overall. 4th axis on lathes can be quite frustrating initially and for when drawing is wrong. I’m going to need to explore new these WIERD energy drinks. I’m looking at your site. I’m also figuring on using Mastercam free version combined with my 1st real milling Mastercam book. Hard drive only 1 GB with Win10 though. That will take lots of backup thumb drives.
I just crashed the cnc lathe I run. Forgot to turn on the optional stop. The lathe is a semi cnc so we hand change tools and for some reason when we convert the shop floor to g code it puts in M1's instead of M0's. Hit the tool change and it passed thru thinking a shorter tool was in there and ran the previous tool into a 12inch diameter aluminum fan casting at 650 rpm and lunched the part over 100 feet across the shop and broke 6 of the 12 blades off and scattered those all over the place. Btw it is an engine lathe style machine so just the guard in front of me and one covering the chuck the rest of the machine is open. It was Not pretty.
@@encyclopedia843 you miss understood. The program requires multiple TOOL changes. If you put an M30 in it restarts the program which would mean I would have to change the tool then search threw the program to start the next tool. It also restarts the cycle timer and the machine has a part counter on it so it throws the part count off.

@@encyclopedia843 as I stated above all of our tool changes are by hand.

A lot of these you can hear the sound of the machining sound like the way that it shouldn't sound and you know that something's wrong with the speed and feeds or the depth but these guys keep pushing it and then they're tool breaks 🤣 Machining should never sound as violent as some of these are before the crashes or the tool breaks happen. It should usually sound pretty smooth and usually you can tell if something is off just by the sound and if that's happening you need to hit that stop button. If you don't chances are there's going to be a crash or you're going to at least break a tool. And even if you just break a tool chances are you ruined your stock while you broke that tool. The lathe crashes are so funny. I think in one of those I saw the guy do a tool change right into the stock somehow😂 Must have forgot to rapid home prior to entering that tool change or something lol. Ever since I became a machinist a couple years back I really love these videos. I know one of these days I'm going to crash. I just hope it's not as violent as some of these ones. I know some servos were definitely ruined in this video 🤣
I’ve been a machinist for 800 years and I’ve never done anything wrong. Fuckin new guys are always scrapping parts and they can’t even read a vernier scale!
I'm not CNC, but I operate some large production machines. Its funny to watch these....because the machine doesn't care. It will just brute force and tear up anything in its way.
Yeah and people around you (mostly some people who are just cutting sticks on a saw) are smart like a fuck, nobody understands what one little typing error can destroy the machine, they should really pay more CNC programmers and operators because you can't even sleep because of that responsibility, you are scared what will happen next day and you know that there is noone who could help you because you are probably only person in whole factory who can kind of program that, you just have to find out everything and it takes years, when you are testing some new tool or new product, you will crash it almost always, people are constantly asking why I am am there watching it with controller in my hand when "it works by itself and you don't have to be there" ....they have absolutely no idea. In wood factory, each product can be atypical, you can't alway dry run everything, you have no time for that and it takes years to be really sure what machine will do. And with those modern machines with cad-like software, you can't be sure that it's gonna do what you expected, that's why I prefer older machines where I can type G-code directly.
hydraulics are strong on cnc machines .. something many forget is the centrifugal force on the claws, the faster you go the more hydraulic pressure to fix the workpiece, ,, you have to be careful with too many rmp on large workpieces and stikout
Most of not all of these clips are result of poor choices and poor machining practices, some of them would be even be totally avoidable had the operator been paying attention while proofing the program.
All of theese people in the video are not trained machinist or cutting machine Operator. Very very stupid mistakes. You cant hold a aluminium part with double-sided tape on a milling machine.🤦♂️ Some of theese "mistakes" looks like they were on purpose.
noone watches noone thinks about proper partfixture noone adjusts the speed and feeds to the clamping situation...just a pain in the ass to watch for a programmer
6:31 you drill i not see you stop and change direction. next tool it wrong way. again. first run mean not run it. use single block and look what is it doing. why peepol so dumb. machine only do what programmed. pragram can have error. you are just human who cant use single block or feed override on first part. fixing take longewr than you would loose time
Amasing with all these fantastic amasingly uber alles and everyone else are just some dumbasses who always makes mistakes and fuxk up machinist we got here in the comments... If you are so damn perfect and never made mistakes you are not true machinists.... Dont understand why you dont start your own shop.....if you are so good in programming and running the macines, you would be nr 1 in mo time and have a shitload of money....and would not waste your own and everyone else time here..

noone watches noone thinks about proper partfixture noone adjusts the speed and feeds to the clamping situation...just a pain in the ass to watch for a programmer
My wallet is being hurt
Every mistake has to be paid in money

6:31 you drill i not see you stop and change direction. next tool it wrong way. again. first run mean not run it. use single block and look what is it doing. why peepol so dumb. machine only do what programmed. pragram can have error. you are just human who cant use single block or feed override on first part. fixing take longewr than you would loose time
Some basic mistakes
Haha, look for all that noobs....
