I was assigned in our metallurgical lab to perform a Variable GR&R for our tensile machine to meet requirements for our PPAP submittal. Since our 60 min yield strength product was supplied to this customer it was selected for sampling. Ninety samples were selected ensuring they were selected randomly. This number of samples were required since a tensile test is a destructive test. Our three lab technicians which normally operate this equipment were used to perform the analysis. The results of the analysis surprised me, and I have checked and rechecked the analysis. Two different programs were used to assess if one of the programs may have been corrupted. The following results were obtained: Appraiser Variation 0.0% while the %GR&R was 89.57. Could you provide me with some assistance in the interpretation or what my next steps should be?
