Standards on Inspection of GD&T parts
I don't typically have to step-in to the role of a manufacturing engineer, but I got drag into one with the new job, because the QC/QA inspection was done haphazardly. The issue at hand was that the inspection of a cam surface profile and that of the reference datum flatness was done with way too few inspection points, and out of spec parts managed to snuck in.
So, my question is... Is there any sort of standards that govern how the machine shop or the QC guys do their inspections per Y14.5? Like how many points of measurement they suppose to take to check if the surface is flat? I really hope they did more than 3. LOL It's mad to think that after all the work of doing the tolerance analysis and specifying the GD&T, someone can undermind all that by cheating on doing a low resolution inspection.
I really don't want to spell out how to inspect the parts on the drawing, and seem to recall seeing some ASME standards on this some years ago, related to Y14.5, but can't remember what that may be. Anyone with more manufacturing and inspection experience know?
