Gage Pin Gauge R&R - Our calibration guy said he doesn't know how to do one

My customer wants the same thing: a gage r&r on a gage pin. How can I perform an r&r on a pin whose size doesn't change?

The pin is a .188+ pin. I can measure it all day long, it's still .188+.

I can enter all those identical measurements into the gage r&r template my customer has provided. The template will not give the pin any statistical score because there is no variance to the data. The pin is always .188+.

The customer will not accept the gage r&r unless the template assigns the pin a statistical score.

I am confounded.

Melanie,

You can do attribute R&R.
