For The Machinists Out There...
I got this in a text earlier today. My response back was "BTDT".

Julious about to not take to much more of that sh*t

As a machinist, I would love to know how they managed to throw that out of the mill. The only thing I can think of is they did not tighten the vice or clamp it and fully buried a endmill in the part.

I hear that every day. Every. Day.

I work 2nd. I've come in on 2nd to find a drill bit in the CNC machine that was broken for over 6 hours of production on 1st. every single hole was bad. I dug through the pallet of parts until I found the broken drill bit stuck in the hole. yet somehow all his inspection reports (every 10th part is supposed to be inspected) were fully filled out and it said all his stuff was just fine. within tolerance.
we set aside all the broken ones, fixed the problem, and made parts all night. at the end of the shift we put a few bad parts on top of the pallet and left a note for the dayshift manager as to what happened.
sure as sh*t that 1st shift guy tried to blame 2nd shift for all the bad parts, and claim the 2nd shift good parts were all his. they didn't fire him because he has some sort of distant relation to the production manager..like 2nd cousin or something.

My exact question. WTF went wrong? How'd a workpiece THAT BIG get loose?

I wish I knew more about that scene, but maybe it's best I do not.

I asked the 1st shift cranks machining operator what causes most quality spills. His answer, 3rd shift.

Bet the boss's son will get a promotion out of this one...

I wonder why it didn't have limit switches to prevent that.

The spindles empty. I think this must have been a faulty over head crane operator.

Would someone care to explain what we are looking at ?

That's a large format Horizontal CNC machining center that someone dropped the part on while unloading it. My rule of thumb is if I can't lift it, I don't machine it. Unfortunately I'm really strong though.

Looks like a machine table. Or possibly part of a fixture. Either way, hideously expensive, heavy as hell, and major damage to the enclosure if not the spindle. Well into the 5 figures damage range. Job-ending without a really, really good reason (like, somebody ELSE programmed it).

B Rad , my bosses son would walk in with a tape measure and ask the weight capacity on a machine. I told him 50 lbs or less. I'm not blowing my knees or back out so you can trade my labor for a round of golf.

"BTDT". We knocked the tombstone clean off a brand new Mitsubishi 50 taper Horizontal once. That was kind of exciting. I ordered a custom post from Mastercam. It was calling the same H value twice. The second time way down in the actual tool path. Fortunately the spindle and the draw bar survived. If you jumped on the parameter page of those controls down to the servos they named them "no stoppers". They were right.

Makes me really glad we only had lathes and milling machines back in my day.

Retired machine maintenance for a large tractor manufacturer who shall be nameless here. We called it an id10t error.
