Gauge R&R Studies

Hello all,

Say a fixture comes with 2 locators, an RFS locator and MMC locator.

Someone at my shop is telling me I need to do a GR&R on the MMC stab pin, but I feel like it's a waste of time. Our process is to use the RFS pins for fixture checks on the floor.

Does your company require a GR&R Study for both the RFS and MMC Stab pins? Seems a little silly to me.

Thanks

it IS a waste of time to do an R&R using an MMC pin as those DO NOT 'locate' the part on the fixture, those are to allow the OPERATOR to change the location of the part to try to balance the entire part into tolerance.

if they insisted on something like that to me, I would have intentionally done everything I could to make it fail. pull to the front on both pins for one part, push to the rear for another, pull one end, push the other for the next, and push/pull for the next, etc.
