Modeling and verification methods for the inspection of geometric tolerances using point data

The ability to specify, produce, and verify parts with sufficiently small variations such that they are functionally equivalent is vital to the success of mass production. The amount of allowable variation in a part is specified by tolerances. To ensure a part conforms to these tolerances, inspection methods are required. With the increase demand for flexibility on the factory floor, a programmable inspection tool, known as the coordinate measuring machine (CMM), has become popular. A CMM is programmed to collect point data information from the surface of a part. This data is analyzed by verification algorithms to determine if the part conforms to the tolerance specifications. Since CMMs determine the conformance of a part based on point data information, methods for reasoning about tolerances based on this type of information are required.
