In light of a gage R&R that will fail (will post the results when complete) on a $4K that someone in my company decided to purchase without the input of Quality, what has been the worst Gage R&R results you have seen from a gage?
From international vocabulary definitions, I think it's strange to get better results in reproducibility than in repeatability...
repeatability condition condition of measurement, out of a set of conditions that includes the same measurement procedure, same operators, same measuring system, same operating conditions and same location, and replicate measurements on the same or similar objects over a short period of time
NOTE 1 A condition of measurement is a repeatability condition only with respect to a specified set of repeatability conditions.
reproducibility condition condition of measurement, out of a set of conditions that includes different locations, operators, measuring systems, and replicate measurements on the same or similar objects
NOTE 1 The different measuring systems may use different measurement procedures.
NOTE 2 A specification should give the conditions changed and unchanged, to the extent practical.
I am presuming you are validating a fixture holding multiple identical parts. Your Gage R&R should be "Crossed" in this instance, where one operator physically reorganizes the parts between fixture positions, maintaining part traceability.
When the crossed operator's data can effectively still track those parts, you have better reproducibility, but crappy repeatability.
Also, if you have poor work instruction that makes operator 1 load parts differently into fixture, it would produce operator bias that ops 2 and 3 might not have... which would result in crappy repeatability.
