I have 2 CMM, 1 is still within calibration, the other is about due for calibration. I want to extend the due date but want to prove.
If 1 operator inspects the same part, on these 2 CMM. And the results were lightly different (example: CMM 1: 0.0040, CMM 2: 0.0048, both are still in specs).
Can I tell that the CMM 2 is good for use? Or do I need to do GR&R?
thank you so much!
