Re: Validation of Gauge R&R program
Howard Atkins said:
Some years ago I saw a booklet from Ford as how to validate Gauge R&R programs.
At last I have found a workbook with the information.
Attached is a workbook which has values and results to check that the programs you are using are correct.
Enjoy
I try to calibrate one Gage R&R variable MSA sheet posted in this site and resulting R&R is not the same with Ford standards.
I try to analyze the K1, K2, K3 constants used and I found out the constants in the MSA tested sheet is using 5.15 instead of 6 (Ford is using Six sigma for K1,K2 constants in the calibration sheet). Instead of K1=5.15/d2, Ford calibration is using 6/d2 for the standard deviation(six sigma standard).I have try to fix the constants the results are ok.
Attached is the corrected and calibrated sheet with Ford standards. Thank you Mr. Atkins for the useful validation program.
