Practical implementation of a STEP-based architecture to provide a fully integrated and interoperable platformof data exchange has\r\nalways been an intriguing issue. A variety of CAD/CAM environments are struggling to embed and support STEP standard and its\r\nprotocols in order to seamlessly operate within global data exchange. However, apparent paucity of efficient and reliable structure\r\nfor data communication, manipulation, and restoration has remarkably hindered the desired progress. In this paper, taking these\r\nshortcomings into account, a practical architecture is introduced and STEP-based agents are implemented and installed on the\r\nplatform.Moreover, feature recognition, interaction, and machining precedence as crucial issues of CAD/CAM research have been\r\nconsidered in developing the interoperable platform. Seamless integration and interaction of CAD/CAM modules are provided in\r\nthe proposed system. The prototype is finally verified and discussed through a case study.
