Re: What is Gauge Capability? Dial Thickness Gauges and Digital Vernier Calipers
I ran the number and graphs. It looks like your major issue is inadequate gage resolution for the part variation. This will have to be corrected before you can interpret any of the other criteria. Can you repeat the study with a gage resolution of 0.0005 or 0.0001?
There also appears to be differences in the average between operators, but this cannot be definitively stated because of the resolution issue. I suspect that once you resolve the resolution issue that it may be the next issue to address. Repeatability may or may not be improved by the improvement in resolution, so you may also have a problem there.
What are you measuring? Could form variation in the product cause repeatability problems for you?
