One of our inspectors at a sister plant handed me a program with an iterative alignment to 22 different features. It's a machined aluminum part on a fixture. The program only iterates it one time (set to 1). Surprisingly it works, with one exception. A single reading on one the the features reports the same number EVERY TIME. And it's EXACTLY at nominal, for every part, every run. Can't figure out why. Their customer isn't buying it. I've since re-written the program with a straight alignment between the two datum holes. I get similar results on the inspection report except I DON'T get the same exact reading on every part on that same feature. I'll post the code for it as soon as I figure out how to copy it from PC-DMIS and post it here (as well as the CAD shot). Been a while since I've done that on this forum. Gotta relearn it... The coding for it is LOOOOONNNGGGG. 22 features takes up 3 sheets of paper. Any ideas as to what's happening?
