Checking an expensive part on the CMM. I made a quick program because it was urgent. "Proved" out the program for moves and such. Ran the same part multiple times. CMM reports a large deviation on a critical diameter along a taper and everyone was scratching their heads trying to figure out what went wrong. Management almost conceded to scrap that part. I was asked to re run it again just to make sure and I find a point out of place on my cone construction. It just took 1 apple to run the bunch. Point was accidently taken in a tiny grease hole and I didn't foresee. I used paste and pattern and didn't think twice about it. I re-ran the part and the diameter is nominal, $40k part passed. I'm a genius and an idiot.
At least you got it all figured out. I think the key is not necessarily to avoid making any mistakes. Mistakes happen. The key is to find and fix mistakes before they become problems. You did that, so I think you won the situation.
