Study And Implementation Of Flexible Integration Of CAx Heterogeneous Systems Based On PDM

Various CAx applications(CAD/CAPP/CAM) are usually used dispersedly and independently in manufacturing enterprises, which leads to repetitive datum, sporadic transactions and independent operations. For all product information can be managed as a whole in Product Data Manage (PDM), the integration of CAx applications based on PDM is paid more and more attention. The traditional solution is mostly based on open customized interface or component, which demands collaborative design and reconstruction and providing a great lot of open interfaces and components. But this demand is beyond practice for the restriction of applications' frame and the degree of cooperation.Aiming at the shortage of traditional solution, the integration technology of heterogeneous systems is given research. Combined with design principles and reference model of integration, a solution of flexible integration is put forward based on the analysis of principium and requirement of integration. The key modules are designed and implemented by the use of integration agent, component and message-driven etc. The design and implementation of PDM/CAx system integration based on component and message-driven are elaborated in this thesis. Information transfer and function calling are realized by using integration agent and message management server. With this technology, the integration of PDM and CAx applications is realized in a unified and expandable manner. The coupling degree of system integration is decreased and its flexibility is improved. According to this solution the integrations between Kaimu PDM and mainstream CAD, ERP, Kaimu CAPP are implemented, which validates the feasibility and efficiency of integration solution. Some possible research directions and emphases of integration are given in a further step as the summary of this thesis.
