I am doing an MSA on a Snap-On torque wrench. It is a simple dial wrench with a range on 20 Nm. I am using an MS Excell worksheet that I got from the Cove to create a Bias & Linearity Report. My question is what is the importance on percent bias and percent linearity? When I look at the numbers all I am concerned with is that the bias of the wrench does not introduce a significant error to the measurement and that the slope indicates that the wrench is linear throughout its measurement range. Why do I need to see what percent of the bias accounts for the total process variation? Thank you. IP: Logged |
