.... There are several generally accepted methods for performing R&R studies ( 3 , 4 , 5 , 6 ). Standards for “adequate” measurement precision can be established from the references. For example, the AIAG Reference Manual states: Guidelines for acceptance of gage repeatability and reproducibility (%R...
