Feature extraction and recognition information system for manufacturing prismatic part

Abstract

Feature extraction and recognition information systems are now widely located as a foundation for formulating an automated process planning system. Many methods have been reported in the kinds of literature, but a few of them acquired a status of generic methodology. In this research work explains the concept of automatic feature recognition system using CAD model neutral file in the format of ISO 10303 Standard for Exchange of Product model data (STEP) AP-214 to identify the hole feature of the CAD model. The geometrical information of the part design is analyzed by a feature recognition procedure that is created specifically to extract the features from the 3D CAD model based on geometric reasoning approach. Finally, a sample application description for a workpiece is presented for demonstration purposes.
