Abstract

This paper reports on a system that bridges the gap between computer aided design and metrology activities in the life cycle of a mechanical product. It completely automates the process of programming coordinate measuring machines. Accessibility of surface features to probes is efficiently computed by using computer graphics hardware. This information is used by a high-level planner based on constraint satisfaction techniques to determine setups, probes and probe orientation. High-level plans are refined so as to produces operation sequences and probe paths by using a combination of probabilistic roadmaps and travelling salesperson techniques. Experimental results are presented for industrial parts.
