Automated feature recognition is considered a critical component for the integration of Computer Aided Design (CAD) and Computer Aided Process Planning (CAPP). In feature recognition most current systems have difficulties in recognizing interacting features because of the destruction of characteristic adjacency relationships in the feature boundaries when interaction occur. Therefore in response to the problem, the application of rule based method is outlined in this research for the implementation to specific features with and without intersection. This need to be extended to thin wall parts, to support design for manufacture for injection molding and casting process which have some commonly used feature to be recognized especially feature with intersect. The proposed method is implemented to the feature with and without intersection such as through hole, cylinder boss, blind hole and other six cylinder boss with specific intersecting features. Three selected plastic parts with several common molding features also has been used for the case study. The proposed method is tested using Graphics Interactive Programming (GRIP), and implemented on the Unigraphics solid modelers. The results show that the proposed method is successful in recognizing the selected features with and without intersection especially for cylindrical feature.
