Gage R&R Study - Appropriate sample collection and size for a Gage R&R Study
Perhaps someone here can help us settle a dispute...
We are planning a gage R&R study for a checking fixture that was recently recieved and there is a difference of interpetation as to how the sample pieces should be selected.
The study will be conducted using the 10x3x3 method. We have 100 pcs to choose our samples from all of which have had 100% layouts completed. One opinion is that the 10 pcs should be selected that reflect the mean tollerance band for the measuremeants that will be taken. The other opinion is that the 10 pcs should reflect the greatest range with even distribution along the tollerance band for the measuremeants that will be taken.
I would like to get some further clairification on this topic from people here with greater understanding of the concept than either of us so please expand upon your reasoning as this will help us to gain a greater confidence level in the work that we are doing
TIA
