Based on current methods of calculation, it is necessary to define the total tolerance zone as a con-
stant. To do this, and also to take advantage of the bonus tolerance gained from this feature of size as it
deviates from its MMC, there is need for alternative methods of analysis. The following matrix is a proposed
method of analysis. (See Table 25-3.)
25-6 Chapter Twenty-five
Table 25-3 Analysis Matrix
Gage Repeatability and Reproducibility (GR&R) Calculations 25-7
25.3 Summary
This chapter defined opportunities that will spur future research activities and should have made clear
many of the steps needed to determine a measurement system capability along with the reasons for strict
and aggressive controls. Discussions have started in 1998 within standards committees and universities
to concentrate resources to research and develop standards, technical reports, and other documentation
to further advance these analysis methods.
