Hello Every one... I am trying to do a GR&R on a height gauge, The nominal as per drawing is 10±0.1mm, all my samples are reading 9.91 and few are 9.92mm, when I enter the data in Mini Tab, I got a result which is over %10 which means is Rejected GR&R. If I manipulate some samples (by deforming them) to read 10.0mm or 10.05 then I have a better result and can make it under %10 which is Good. But I don't want to do the second method, Why the result is so bad when Measuring the original samples? What I am doing wrong? any help is appreciated. ( I use 10 samples/3 Operator/3 trial).
