Gage R&R - how to conduct?
How do I conduct a Gage R&R study correctly? If I do 3 trials, use 3 appraisers, and 10 parts. Do I want the parts to vary or not? I thought about using gauge blocks rather than parts because I know that they are accurate and what the measurement is. If I have 10 parts do I have my appraisers measure the same 1 dimension on all 10 or measure 10 different dimensions on each part?
