I'm working with another facility and came across what I believe is an error with the way they are completing GR&R's.
For example:
The part length is 1.00 +/- .005".
For the formula to calculate the repeatability:
%TOL = (EV / TOL) * 100 = xxx
They are using .005 for the TOL rather than .010.
I've always used the full process tolerance.
Who's correct?
Thanks for the help!
