A question came up that has a lot of debate,
If a Attribute GRR has already been performed and completed with passing results for both Pin and Ring gages, and further down the line the tolerance of the feature becomes tighter and we change to a tighter class of Pin/Ring gage for the inspection of the feature, does the GRR have to be re-performed or since the method itself has not changed we can still use the same GRR results since Attribute does not challenge tolerancing?
