I've been having an issue measuring concentricity. Could someone explain best practices for checking concentricity between two holes/pins at opposite ends of a part? The parts very from 4" to 12". I can spin them on the datum on my V-Blocks and show them as basically perfect with an indicator (indicator/v-block has been certified), but when I run them on the CMM I show them as being out of tolerance by like.. 1mm~/0.040". I have no idea if I'm just setting up the feature wrong or what, any thoughts?
What is the length of the datum? Are you measuring the entire length of the datum as a cylinder? How many points? How many points for the measured feature?
A print snippet or code snippet would be good for assessment as well.
