CNC CRASH - FAIL COMPILATION | 😲 You won't believe your eyes 👀 

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.

I am a former machinist. This hurt to watch. Too close to home still.

seen this today sunday and i’ll be absolutely paranoid tomorrow at work, thanks

I've only been a machinist for a little over two years and was holding my breath for most of these, gotta change now

I find myself being nervous watching this, adrenaline and heartrate goes up

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.

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.

You can hear the spindle bearings fail on a couple of those...you are not a machinist until you have broken something really expensive.

a lot of that was excess stickout on the lathe.. Not even excess , just negligent stick out.

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.

love how we was all like wooooaaahh! on the fly cutter video. that fly cutter was being fed waaaay too fast. unless the video was sped up..

You ever have one of those days when you're absolutely convinced that the equipment hates your guts?🤬

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.

Most of these could've been prevented by actually watching the program as it ran and watching your coordinates.

Watching these CNC crashes made me reconsider my career choices...perhaps stand-up comedy is less stressful 😅

I'm watching these from behind the sofa!

i would really love if you guys put the cause of fail in every situation

Dang, that was painful to watch! 😅

Está muy bueno el video.

Watching these sorts of vids gives me such fucking anxiety.

Some people just dont get it, never will

Aww man!! You gooched it!!!

Watching some of these prior to the crash. You get pucker feeling happening knowing the shits going to hit the fan soon.

Kind'a make glad I still have my old manual lathe. I think some of those were pretty costly.

This video gave me such severe pain in my heart that I couldn't watch it until the end. I would rather watch a horror movie than watch this video.😱

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.

やらかしたときは心も折れるからな その日一日は落ち込む

Next time full screen please...

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.

Fmax I Love it :'D

Single block peeps when you are running new programs and new setups.

starting full throttle is a stupid way to save time

Why this frame around the video? It is tiny.

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

More painful to watch than BME Olympics

There are 2 types of machinists in the world. Those that admit they have crashed a machine and those that lie about never crashing a machine.

Distance to go read outs and rapid override knobs are on these machines for a reason

I love that they're all recording before having proven programs. 😂

3:16 - shit, I didn't expect that, I almost jumped away from my computer 😀

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.

At 9:35 they are just trying to be efficient. Cutting that part while flame polishing.

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 🤣

What's the reason for crashing tools into the work piece. I don't get it.

👍

If you don't learn from your fault you can't improve yourself

This video is stressful to watch. I know the stress of a crashed machine. Its a dreadful thing.

무서워 젠장

Every mistake has to be paid in money

CMS-02 Artis solutions!

If you aint done one of these fopars you aint never worked a cnc

First day work

4:16　これやったことあるけどTナットの溝も駄目になるから鬱になる

Bad enough destroying company tool ouch watching your workpiece being destroyed I feel your pain

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!

My wallet is being hurt

計算できないバカと金属を粘土と勘違いしてるバカのオンパレードwww

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.

Haha, look for all that noobs....

Some basic mistakes

CNC?

4:15 what happened??

I don't know if I'd call them crashes just expensive fuck ups.

o yes, i believe..

I’ve just retired after 30 years cnc work . What a set of dummies 😆

加工が終わって、刃物を逃がすときに衝突するケースと、クランプが甘くてワークが外れちゃうケース、刃物が耐えられないケースは正直仕方ないが、 実加工の前にZ軸がリミットを越えないか確認せずドカーンは論外　ちゃんと確認しろ

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

Omnissiah does not approve.

cringing while watching

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..

. machines cnc very bad

на это больно смотреть, садизм какой то
