Thank you a lot for your answer.
One more question I have:
- I have 30 measured data for dimension 1, measured by operator 1 and operator 2
- I have 30 measured data for dimension 2, measured by operator 1 and operator 2
How is possible to calculate Pp correctly, please?

Hi all.
Could you, please, help me, how to set up GRR for destructive testing method?
I have done pull test method on the samples.
I can do pull test once on one sample. Then the sample is destroyed.
How can I set up GRR study?
Is it correct to prepare samples by the following?:
30 samples measured by 1. operator
30 another samples measured by 2. operator
30 another samples measured by 3.operator?
The samples are made from the same process (1 welding machine), produced one by one during short time.
How can I calculate EV, AV, GRR correctly?
