Abstract:
1. A machine-readable medium for programming a computer to determine positional error and remaining feature related tolerance for a plurality of manufactured internal features on an object, said medium including processor executable instructions comprising: determining a true position for each of said plurality of manufactured internal features; determining a framework from said true positions; determining a location for each of said plurality of manufactured internal features; determining a size of each of said plurality of manufactured internal features; fitting said framework to said locations of each of said plurality of manufactured internal features to determine a fit framework; determining the transformed relationship between the framework and the fit framework; determining a relation for each of said plurality of manufactured internal features to said fit framework; organizing each of said relations into a single association; organizing the location of each of said plurality of manufactured internal features relative to said single association; determining said positional error for each of said manufactured internal features from said single association; determining a common region contained within said organized plurality of manufactured internal features; determining a maximum inscribed circle within said region; determining the diameter of said maximum inscribed circle; determining the center location of said maximum inscribed circle; determining the transformation of the center location of said maximum inscribed circle from said single association; and determining said remaining feature related tolerance from said maximum inscribed circle.
