Gauge R&R Question

#1
My summary report on a crossed gauge R&R seems to imply that repeatability is acceptable, but reproducibility is not.

"Can you adequately assess process performance?" is 22.4%

"Can you sort good parts from bad?" is 91.5% !!!!

When I go through the data (3 operators, 3 tries each, 10 parts), every operator was able to pick the parts that were out of spec, and the parts that were in spec, all 3 times. They all matched as well (meaning all 3 operators agreed when a part was good or bad).

Are there any obvious tips about what could be going wrong when this happens?

First, you might want to post your Minitab output as a PDF file, because not everyone will be able to open a native Minitab file. That said, the purpose of GR&R is not to find out who can identify "bad" parts, and in fact there's no reason to use anything but parts that represent normal process output. The primary purpose is to verify that the right measurement system (gage + operators + parts) has been identified. The statistics will tell you if the system is adequate for inspection, process control, or both.
