Automatic extraction of manufacturing features from cad models for capp (a simple and logical approach)

摘要

Automatic Feature-s recognition is likely to be an essential requirement for future integrated design & manufacturing systems and in the development of fully Automated process planning systems. A CAPP system essentially provides an effective platform for an integrated CAD-CAM system. Majority of the current design and manufacturing data used on shop floors, is associated with CAD models. The present paper discusses in brief about the role of CAD in CAPP. Also, an overview of research in extraction of feature-s from CAD models is taken. Most of the systems suggest complex algorithms which, new develpers find difficult to implement. Hence, the development such a system for 2-D CAD models has been described completely.
