Abstract: Based on the analysis on inspection planning for machined parts manually, computer aided inspection planning as a automatic approach is proposed, and expert system technique is employed in the research on computer aided inspection planning and system development. BHCAIP, a knowledge-based computer aided inspection planning system developed by Beijing University of Aeronautics & Astronautics, is presented. It can generate automatically inspection plan for rotational components, from feature - based computer component model, and translate the inspection plan into DMIS format file for CMMs which has DMIS processor.

Key words: DMIS, Expert system, Inspection planning
