I use two CMM machines and sitting here wondering about the correct use of our MSA procedure.
I will outline a typical procedure and maybe someone can give me some feedback:
We measure car interior components, a lot of "soft" parts which makes the MSA quite difficult.
1. We are two operators who measure ten times each on a single part, why would we use more parts ? is it not the R&R of the fixtures & operators we want to test not the test part itself, are there any demands to use more than one part per test ?.
2. We measure 6 points, two in each direction - X, Y and Z, usually on a flat surface with quite high tolerances - if there are any such surfaces. Is there anywhere that states that difficult areas with small tolerances should be measured ?
Thanks for any feedback
