%X Practical implementation of a STEP-based architecture to provide a fully integrated and interoperable platform of data exchange has always been an intriguing issue. A variety of CAD/CAM environments are struggling to embed and support STEP standard and its protocols in order to seamlessly operate within global data exchange. However, apparent paucity of efficient and reliable structure for data communication, manipulation, and restoration has remarkably hindered the desired progress. In this paper, taking these shortcomings into account, a practical architecture is introduced and STEP-based agents are implemented and installed on the platform. Moreover, feature recognition, interaction, and machining precedence as crucial issues of CAD/CAM research have been considered in developing the interoperable platform. Seamless integration and interaction of CAD/CAM modules are provided in the proposed system. The prototype is finally verified and discussed through a case study. 1. Introduction Since more than a decade ago, interoperability and integration in CAD/CAM environment, have been notably investigated. Quick and faultless data communications throughout product and process development are becoming imperative day to day. This is mainly due to disseminating vendors and complex-structured organizations of design and manufacturing. Needless to say, promising progress in developing neutral standards and their pertinent extensions within recent years are construed as driving wheels for the integration vehicle. Neutral standards do not ordinarily depend on any proprietary application or platform. They are mostly easy to be dealt with, manipulated, and interpreted while having a potent structure to entirely capture product-lifecycle data. Loosely claiming, future generations of product data management (PDM) must be neutral format-compliant in order to fully achieve interoperability [1, 2]. STEP (the Standard for Exchange of Product data) has played an underlying role in implementation of CAD/CAM integrated systems [3]. Taking STEP¡¯s numerous advantages into account and relying on its unique capabilities, this research proposes an integrated CAD/CAM architecture to provide the organizations with an interoperable platform of data exchange. STEP-compliant agents are then installed on the platform and a system which benefits the merits of the developed platforms is designed and implemented. Feature recognition, interaction, and machining precedence are some crucial issues that are particularly dealt with through developing the proposed prototype. This achievement
