Warning: Stop touching the part to check if it's still hot, you're gonna get burned and scrap it
I keep seeing guys on the floor reach over and tap a part with their bare fingers maybe 30 seconds after it comes off the mill, then they jerk their hand back and knock the whole thing off the bench. Happened to me twice my first year at a shop in Dayton, second time I dropped a 6061 bracket that had 3 hours of surfacing in it right onto the concrete and folded a corner. The funny thing is the machine already tells you everything, the spindle load drops, the cycle light goes green, and if you're running a thermal camera or even just watching the coolant start to steam off you know it's still north of 200 degrees. We have a $40 infrared gun hanging on the cart and nobody uses it because they think fingers are faster. I get it, you want to know if the part is stable before you pull it out of the vise, but your hand is the worst gauge in the building. Last week a new guy did it on a titanium job and not only burned two fingers he twisted the part in the jaws and we had to re-indicate the whole setup. Do your shop a favor and grab the gun or just wait 90 seconds, has anyone else watched somebody wreck a good part over this?
