Top 10 Dangerous CNC Crash Fail Compilation

Top 10 Dangerous CNC Crash Fail Compilation

[wholesome]

reminds me of a saying that a guy at my shop told me, "don't you hate it when the machine does what you tell it to do, and not what you want it to do?" lmao

[yawpaw]

Gcode like: HaHa! U missed a decimal! Now i willdrive this spinny thing right into the center of the universe.

Who would have thought that the "Top 10 most dangerous crashes" ended up being a bunch of minor tool breakages and other generic crashes with very little in the way of actual danger

In my experience I've learned to never ever trust your program on the first run. Always control your speeds and feeds. I've caught myself many times with something that would have been catastrophic. Every video in this tells me it was a first run and no one cared to be cautious. Telling the boss you destroyed the spindle without verifying the first run has gotta really HURT.

1. Expectation of this video: Stolen video of crashes from 10 years ago
2. clicks anyways
3. Result: Expectations met 10/10

[paulferri]

These are mostly due to poor machine programming, too fast of feed rates, not programming proper clearances, or a poor understanding of the forces at play

20 years ago I worked in a massive machine shop making gas turbine parts. A huge VTL (15'+ wide) was making a pass and something was dramatically wrong. The casting at the top of the cutting arm broke with such a snap that people all the way at the end of the shop heard it. We're talking about a shop that is over 1/8th mile long full of running equipment. That machine was down for months and it took techs flown in from all over the world to fix it.

1:20 When that happens, it's not just replacing a tool or scrapping a part. The whole spindle has to be aligned and maybe replaced. That is scary.

[theWilldabeast]

1:35 was pretty atrocious, that spindle head probably just took some serious damage and will more than likely need to be heavily repaired or replaced.

I've made those errors before too, but not doing them again is the key to keeping your job.

As someone who works with these machines on a daily basis it hurts as much as getting hit in the balls with a sledge hammer

[axslinger]

Boss: Can't you speed this up any? We're losing our ass on this job! (Ironically, every place I worked for in my 20 year machining career, they seem to have lost their ass on every job that went through the shop but somehow stayed in business. Go figure.)
Operator: Sure, how much money you got?

[dkuhn]

As a machinist for 15 years none of these would be on my list for dangerous or high risk.

[philtru]

1:20 Half of these would be avoided if you *proof your program!* First run of a program you should ALWAYS ALWAYS ALWAYS stop the tool before it touches the piece, and check the “to go” distance on the Z axis. Youd be surprised how many thousands of dollars a mistake like these can cost.

[Exypno]

it's always so hard for me to understand why someone would run an unproven program at 100% rapid

[captainfarrell]

For 3 days I told my shift supervisor that the chuck in my CNC was not reacting normally. For 3 days he told me it was fine. The 4th day the chuck failed and came loose during cycle and wrecked the machine. I laughed at him then got to sit around for 2 days getting paid while the boss fixed everything that got broken.

[knutritter]

There's a universal special term used worldwide if this happens: "F*CK!" 🤣

[Liquid_Mike]

Now if you want some dangerous fails,
_LATHES_ are where it's at

[BlueLineofthesky]

I own a small CNC and looking at these situations I feel like real body pain.

[MaxiGouogle]

What's so dangerous about that?
That's when the end sensors failed, and the 500 kg portal hit the limiters at full speed and flew off the rails...
That's when I really got scared.
