Not necessarily CMM related. Lets say I have a part with an OD with a size callout of Ø1.500 +0.001/-0.000 and the surface has a taper of about 0.002 over the length of the part. At the one end it measures 1.4997 and at the other end it measures 1.5012. How do you report the size of the dimension?
In such cases, I report several diameters indicating the level at which it was measured with a comment about it, then the engineers deal with it, whether it suits them or not.
Yeah. There is no reason to overthink plenty of engineering requirements since most of those folks had only one GD&T semester as part of their BA education. People on this forum often post question before 1st consulting their own engineering staff regarding part fit form function & design engineering manufacturing & assembly processes.
