Abstract
A system is provided which operates to compare three-dimensional models of inspection gages constructed from computer aided design (CAD) data for a manufactured part and standard geometric dimension and tolerance call-outs to three-dimensional models constructed from inspection data obtained from the manufactured part. The comparison is made both graphically, to assist an operator, and mathematically to determine part condition. Parts are found to be either in tolerance or out of tolerance. If out of tolerance they are found to be either reworkable or scrap. Additionally, the system is capable of determining syntax correctness for tolerance standards, defining the sequence of steps for a specific job prior to job execution, performing individual part tolerance conformance analyses and statistical part tolerance analyses for a population of parts, tolerance analyses for mating parts, and generation of tolerance call-outs for fixed and floating fastener features on parts.
