Automatic Features Recognition for Symmetrical Shapes


The future of computer-aided design (CAD) and computer-aided manufacturing(CAM) depends on the ability of their two processes to communicate with eachother and with intermediate manufacturing database. Therefore, the development ofa successful approach to the integration of CAD and CAM will require solution toseveral fundamental problems in planning and geometric reasoning. The firstproblem is the interface between CAD and CAM, that automatic featurerecognition is an indispensable technique to solve this problem. We address thisproblem by developing an algorithm, which is considered an effective approach toextraction and of hybrid manufacturing features of symmetrical parts. Thedeveloped algorithm is based on the syntactic pattern primitive concept supportedby production rule technique. This approach is considered a powerful tool appliedto feature recognition field for symmetrical parts.
