Hello to the group:
I've been tasked with developing training for First Piece inspection, (not FAI).
We are a manufacturing company primarily involved with standard machining, (milling, Swiss turning, EDM, etc.). Lately we've experienced some rejected jobs due to bad first piece inspections.
The causes of the defects were rather simple, (missing features, angles in the wrong attitude, threads not deep enough). It's not lack of training, the people that made the mistakes are the most experienced, (20-30 year), inspectors and are more than proficient to catch the problems.
The reason that I believe that this has occurred is that the parts we produce are micro machined medical components with very close tolerances. It would appear that the inspectors are so focused on measuring the tiny features with total tolerances less than .001" that they "aren't seeing the forest for the trees" so to speak.
My question is, does anyone know of any general guidelines that I can use in my training that will give them a template or guide to follow when they start a first piece inspection, kind of like an overview when they are looking at the part and examining the features.
Thanks for any feedback.
Mike
