||Manufacturers today realize that feature location in part design and production is crucial. In order to produce interchangeable parts in a manufacturing environment, care must be taken that the design is sound enough to allow mating parts to work correctly.
Traditionally, to find the deviation from true position (sometimes simply called the position) of a feature, the open
setup is used. This process involves the use of calipers, height gauges, micrometers, and other hand tools used in conjunction with an inspection plate to take measurements and compare the features position to datums. Following the appropriate measurements, the true position diametrical deviation, D, must then be calculated via the following mathematical formula...
