Haven't been able to find any previous references to this question, but I am sure that some of the members here will have suggestions as to how to approach this issue.
I have been instructed to perform GR&R on an automated inspection cell. There are several discreet test stations in the cell, and it is possible to identify which cell a reject came from.
My question is how to best perform and analyze the study. At first I thought of doing it as an attribute study (the cell basically gives a pass/fail result) however I want to also capture the fact that a part is consistently rejected at the SAME station, demonstrating that the gauging is repeatable.
The other question is how to deal with the reproducibility. Parts are loaded onto a conveyor before entering into the cell, and then are handled by robots through all subsequent stages. The robot(s) are error-proofed so that an incorrectly loaded part will not be processed.
There is no opportunity for operator influence that I can identify, unless I have overlooked something.
Any suggestions as to how to capture and analyze the data?
Thanks
