[Ri...] Posted September 19, 2019 Share Posted September 19, 2019 It is a numerical value of the percentage of tolerance used. This helps you be able to perform Capability Analysis on a characteristic that has a moving tolerance. True Position = 0.1920 - Tolerance = 0.3038 - Percentage of tolerance used is 0.632 or 63.2%. It's weird that it is showing the .MMC with a tolerance of 0.2, usually it's with a tolerance of 0.1. At the end of the day, it's for capability analysis only.
