I Just CRASHED The SMX3100 9 Axis CNC Machine

CNC Machine Crashes! THOUSANDS of dollars in damage can happen in just SECONDS when a CNC Machinist is distracted. CNC Machinist crashed a DN Solutions SMX 3100.

The great thing about CNC machines is they do exactly what you tell them to do. The bad thing about CNC machines is they do exactly what you tell them to do.

[Yogi_Bear]

100%. I was learning CNC and the way I was taught was to load every tool, touch them off then run the program. The guys were telling me I can save time by having the program load every tool and touching them off as I go. Crashed a few tools trying this before I told them to "F off I'm doing it my way."

[russellofcnc]

I told myself I would be very, very careful my first time machining...and I chipped an insert within my first few hours. Left me shaken for sure! I can only imagine the nerves of steel machinists develop over the years.

Donnie is king when it comes to keeping old footage around. Truly helps in the editing.

[filippomontevecchi]

First law of machine tools(in my experience): the moment you feel confident with a machine is the moment you are more likely to crash it!

[Jessie_Smith]

The thing about Donnie is he doesn’t have to be at your machine to hear him talking. You can hear him all over the shop 😂

My old boss (the owner of the company, who had no understanding of CNC work) used to interrupt me, while I was programming and doing setups or repairs, by walking up behind me, and asking random, completely unrelated questions, usually within two feet of me. He didn't warn me that he was there either. One day, he startled me, during a head change on the water jet. I swung around with a 36" crescent wrench, and nearly took his head off. It was close enough to move the hair on his head. He stopped getting close to me, and always waited until I was done, before asking me anything again.

I couldn't agree more. I worked for SecoTools here in New Zealand (now retired) for 28 years travelling the country promoting, testing and trouble shooting customer jobs. One thing I never did was to interupt an operator while he was running the machine. To me it was common sense. I am a qualified machinist and understand exactly what you are getting at. Cheers Ian

I crashed a Daewoo DMV3016 VMC in January of last year. Co worker walked up to me talking while I had to put a hard jaw on top of an inconel pin to clamp it in a set of soft jaws. I was talking to him and forgot to take the hard jaw off the top the vise, closed the door and pressed the green button and then BOOM! Thank lord it was at 50% rapid though. I had run thousands of these pins. Learned a lesson that day and still have the hard jaw as a trophy.

The fear of crashing machines is real! 😬 Great story!

[iizvullok]

A coworker once told me a story about him asking another guy (who worked at a conventional lathe at that time) where to find a certain tool (he was new). The guy working at the lathe went to show him a few tools and asked him which one he needed. All while the late was still moving towards the chuck. Eventually the machine crashed. The tool broke, the part flew out of the machine.

[adammiller]

Couldn’t have said it any better Donnie, I really wish my supervisors could watch this video, I have had instances in conversational programming a Hurco mill, i fat fingered. The wrong offset, and another machinist who was bored running a high quantity part would bug me between cycles, while I was DTG my part luckily I hit the interrupt button just in time before I had a huge Z axis crash.

[CNCMatrix]

I have a saying:

There are two types of machinists, those who have crashed a machine, and those that WILL.

[BogdanS]

if i need to speak to someone that is focused on the machine i always try to stand somewere where the person can see me, and i just wait for him to talk to me when he is ready for it

[deanavitale]

Timely video. Just last week I said to our scheduler (who is assigned to ask each machinist "where are you with this?" a few times a day) "never interrupt them when they are programming - ever". Instead, she stands there and waits. That's just a bad right? LOL Great video Donnie!

[kgranno]

Great video!! Never interrupt while setting up!

[nathanbieri]

Great reminder Donnie! Well done with the video!

[damionparson]

He preached a real machinists sermon here. Well said! Let us get through our setups without being disturbed!

[DjStig]

This makes me smile ... this happened to me at work ... indexed a bore bar straight through the work peice straight into the saftey glass ... Nice to know its not just us amateurs that make mistakes

[liamnelson]

Back when I was an apprentice the guy who trained me up told me he's worked in shops where guys would intentionally delete lines of code or mess with your offsets and I'm so glad I've never worked in place like that
