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?
How many decimal points out are the measured and calculated results to? I've seen some fairly bad results become acceptable if more decimal points are used in the calculations. Truncating the results can result in an artificially tight control limit in the calculations.
We went out to 4 decimal places.
Trust me...this gage is absolutely not repeatable. We had myself, another QE, a quality tech, our manager put a part on and take it off and put it back on and got massive variation.
