This is for my curiosity, I ran into a problem today with one of our machines. We are running a part right now that we are drilling a hole all the way through, please for give me for not knowing the drill size, but we check the hole to see if it is the correct size by using Gage pins.
We use a 0.387 pin for the low tolerance, if it goes all the way through it is correct, and if the Gage pin of 0.392 does not fit all the way through thin it is at the high tolerance. We had one or two parts that the gage pin went straight through. Not one after the other but about 1 in every 20 parts, why is that? I know I am not explaining this the best but just curious!
The parts are copper, and they are sitting against a fixture.
