So in a machining environment, what are your largest pet peeves that really **** you off when you see others do it? My two largest ones are leaving the "T" handle in the lathe chuck and walking off, and the other is quitting for the day and leaving the spindle on the mill down below the vise.
I have witnessed both numerous times cause an accident but luckily, no one was hurt.
In thinking, I think my third one is people that get into a machine and not check things out before firing it up. I don't trust anyone that runs a machine before me, so I check everything. Nothing like a lathe chuck coming off at 1800 rpm's and hitting the floor. A few years back, I witnessed one come off of our LeBlond lathe, hit the floor, spin for a few seconds before it took off. It put a nice hole in the drywall at the other side of the room.
Of course, horseplay will be on everyones list, or should be. When I first started out in the Prototype Shop, we had a 3 axis Tree Mill. This one guy that worked there would wait until my run was over, or when we would go to break, he would change the parameters in the mill to stop .010 above the "Z" reference plane. Default was .100. We went to break and he changed the parameter on the mill. The only thing was....I was through running my part. I cleaned up the mill, picked up my tools, and he came over to run the machine. He had forgot that he changed the parameter. He touched off of his block that he was going to cut, punched in his dimensions, and literally screwed a 1" two flute end mill all the way through a 3/4" piece of aluminum. I just looked at him and shook my head.
