Hello everyone,
I'll expose my problem: I do an internship in a French Medium Sized Company and I have to set up the capability of all the measurement gages (around 300). I have based my procedure to the 4th MSA edition. I have carried on measurement tests with 3 appraisers 16 parts and 3 trials. My problem is, when I start my analysis, should I compare my GRR to the tolerance or to the variation of pieces of my sample? I read in the forum that comparing to the tolerance is for inspection but I did't see that in the 4th MSA edition.
I have an ISO audit in 4 month to check how i perform MSA method so I won't be able to prove it if I choose this method. Moreover, my boss told me that on the short term, he needs to know what instrument can really distinct good and bad parts. The long term will be the SPC.
I'm really sorry for my english, I'm french and I got some difficulties.
