Hello all,

I have a machine that is used to measure the thickness of flat pieces across the width and length. There are 5 thickness gages across the width (set up by an operator for the different widths of parts), and the system automatically collects a thickness data point, for each gage, every 6 inches down the length of the part.

We want to look at the accuracy and repeatability of this system.

My question is, should I perform a Gage R&R for each thickness sensor? Also, since I need a single data point to compare against, should I use an average of the collected data points, or should I use a common data point from piece-to-piece (e.g. 12 inches from the first edge for every part).

Thanks,
Joe
