A SURVEY OF AUTOMATIC FEATURE RECOGNITION

Abstract:Seamless and effective integration of CAD and CAM is increasingly de-manded by manufacturing industries. To realize this, an intelligent interface be-tween CAD and CAM is imperative, since CAPP expects part representation in terms of manufacturing features, whereas CAD describes parts by their solid model or design features. Feature recognizer is exactly such an interface because it can rec-ognize manufacturing features of a part from its CAD model automatically.There-fore feature recognition has been an important research area over the past decade.Much effort has been conducted in this area and many kinds of feature recognition approaches have been proposed. On the other hand, due to the difficulty of feature recognition, there are still many problems with the current feature recognition methods, which need to be solved to make feature recognition more powerful. In this paper, a survey of automatic feature recognition is presented. The representa-tive feature recognition methods are reviewed and their distinguishing characteris-tics are identified. Moreover, the existing problems of feature recognition and the possible solution strategies are discussed.
Keywords:Feature recognition  feature modeling  CAD/CAM
