ABSTRACT

Chapter 9 presents fundamentals of functional gage design implicitly assuming a tolerancing scheme. While the tolerancing rules may give a superficial appearance of being simple and easy to apply, some hidden concerns should be explicitly addressed. The driving force behind interest in these techniques is gaging policy. The original discussion starts in Chapter 5, where it is argued that a specific gaging policy must be selected and included as part of contractual obligations. There are also related discussions associated with measurement uncertainty and decision rules for determining conformance.
