Abstract: Dynamic integration between heterogeneous CAx and Product Data Management (PDM) systems is a crucial problem to be solved in networked-manufacturing, especially based on STandard for the Exchange of Product model data (STEP) through Internet. With the analysis of the necessity and possibility to access STEP file by Web Service, indirect STEP and eXtensible Markup Language (XML) Schema mapping was constructed for STEP data serialization by United Modeling Language (UML). An open architecture of PDM Web Service was presented based on the STEP and Web Service methods. The architecture was applied for the integration of heterogeneous CAx and PDM systems. The internal framework and function modules of the architecture were illustrated in detail. The Information flow was addressed on how Computer Aided Design (CAD) system can invoke public PDM Web Method such as Check-In or Check-Out by Simple Object Access Protocol (SOAP) messages. Based on STEP and Service-Oriented Architecture(SOA) methods, an interface module for the implementation of CAD and PDM systems’ integration was developed.
