We need to validate our test method for a glue joint. We have the spec that we know we are going to be well above and capable of hitting but we still need to qualify the pull test inspection.
What I have is 100 parts made with one operator/one set up/one lot of components. To do a destructive R&R my understand is that you should have multiple batches (lot) that represent multiple parts? Perform a Nested R&R and go from there. The issue I have is with the assumption that these batches would be equal (and the fact that I don't have the resources/time to make more than the one batch I have). Can I instead just do an ANOVA with 3 operators measuring 10 parts and show that there isn't a significant difference between the operators? I have no way to prove the parts are the "same" but all I really care about at this phase is that the operators are the "same", right?
Thanks in advance for your input,
Erik
