I didn’t call out a specific dimension on a machined part; instead I left it to the machinist to understand and figure out what needed to be done without explicitly making it clear.
That part was a 2 ton forging with two layers of explosion-bonded cladding on one side. The machinist faced all the way through a cladding layer before realizing something was off.
That’s hilarious, actually pretty recently I “caused” a line stop because a marker feature (for visuals at assembly, so pretty meaningless dimension overall) was very much over dimensioned (we talking depth, rad, width, location from step) and to top it off instead of a spot drill just doing a .01 plunge they interpolated it! (Why I have zero clue). So it was leaving dwell marks for at least the past 10 months and because it was over dimensioned it all of them had to be put on hold because DOD demands perfection (aircraft engine parts)

The replacement had a 6 month lead time.
