Applications Of XML Technology In Web-based Injection Mold Part Library And Product Data Management

This paper is based on the program which name is "Teamcenter Based Product Data Management (PDM) System Implement and Development" and as an extension of the Key Industry Research program of the Science and Technology Bureau of Ningbo City, which name is "Knowledge Engineering based Injection Mold Rapid Design System". This paper mainly research on the applications of XML technology on product data sharing and exchange, construction of Web-based injection mold parts library and product data management, and propose a model of part parameter information based on XML, construct a part library system platform with dynamic expansion based on XML technology. Meanwhile, aiming at the requirement of information integration from manufacture enterprise, research on application of the information integration based on product data management with XML technology. The main tasks of research are as following:1,Aiming at overcoming the problem of product data exchange and sharing which is met in injection mold design, Some relate study results and trend in CAD product data exchange from home and abroad are analyzed, and also the description method with STEP and XML are studied. A method of mapping between EXPRESS and XML is put forward through researching the feasibility using XML describing product data structure.2,Aiming at overcoming the problems of sharing part library information on the network and expanding the part library, the key technology of construction of web-based part library is studied, for example, the technology of parameter-driven modeling, parts information saving, part library expansion and CAD system secondary development interface. A parameter information model of part based on XML is proposed. And a whole framework of dynamic expansion part library is constructed, and the process of internet parameter driven modeling and the principle of expanding part library are described in detail.3,The integration and encapsulation method of many kinds of software tools used in enterprise is analyzed under PDM environment. Taking AutoCAD as a example, a method of realizing no-gap integration between PDM and AutoCAD using XML as mid-interface is put forward . And as an expansion, the method of realizing integration based on PDM using XML is studied.
