Re: GRR on ID with set of pin gauges

to expand on Miner's point - the resolution is a relative thing. If the tolerance range is small compared to the pin resolution, then you get 'chunky data'. chunky data is defined as when there only ~2-5 possible results in the tolerance range. This will result in an overestimate of the measurement error SD and your R&R will most likely fail.

If pins are the best choice (because you need to detect the minimum through hole diameter) then I recommend using a categorical gage R&R. This would be a more accurate and useful assessment of the measurement system.
Thank You to Bev D for your informative Post and/or Attachment!
