I am attempting to determine whether a gauge used in our production facility is acceptable - both for setting up the line and for measuring product during improvement projects.
We have decided to do two studies:
1) Using 'known' prepared and marked (to ensure measurement of sample in same location) samples within a very small range, conduct a basic Gage R&R study to determine gage resolution/accuracy in distinguishing between small product variation.
2) Using 'unknown' unprepared samples (operators will do all normal prep) representing the normal process variation, conduct another basic Gage R&R to determine the usual suspects (repeatability, reproducibility, etc).
Does this sound like a logical start? What other analyses can be done with the gathered data to make an informed decision about the gauge?
Thanks!
