GR&R on a Pin gage (pass/fail) with multiple checks

[JHunt75]

So I have gage for an automotive part. It checks hole true position @ MMC with stab pins. The gage has 12 holes that it checks. How do I do a GRR on this? I have Minitab, but all I see is instructions for single check attribute gages that are pass/fail. Do I have to GRR each of the 12 holes & make a seperate report for each hole?

@Miner will have the best advice here. My first blush suggestion is that you would pick the ‘worst hole’ OR combine all of the holes as it would be an attribute study

 

[Miner]

If I understand correctly, this is still an attribute gage, correct? It just checks multiple features rather than a single feature. Or do you get variable data?

 

[JHunt75]

Multiple features & I either get pin (pass) or no pin (fail) on each feature.

 

[Miner]

If each feature is independent of each other, I would do what @Bev D suggested and study the worst-case feature. If you also have a pattern, such as a bolt circle, I would perform an additional study on the pattern.
