The Applied Research On The Enterprises' Implementation Of PDM

With continues development of the research and application of advanced manufacturing technology, PDM has become the most important part of enterprises' informalization. During the process of new product designing, PDM make the product data abundantly shared, consequently solve the problem of automative detached island. By taking part in several PDM and CAPP projects, the author abstracted some specific problems occurred in different enterprises and make a deep research on the key technology of the PDM.The first chapter introduces the concept, the origin and the history of PDM in brief and introduces its functional model, the latest technology and developing trends.The second chapter introduces the preparing work for enterprises' standardization-create the classifying coding system. PDM is closely relative with standardization, fully embodied in the implementary process. Completing the standardization before the implementary process is significant.The third chapter introduces the method of exporting BOM. Different BOM plays an important part in the systematic integrating designing with processing based on PDM framework, which almost reflect the whole lifecycle of products.The fourth chapter introduces the method and content of integrating PDM with CAPP on the basis of the relative experts research and taking part in implementing a CAPP project. The sharing and reusing of enterprises' resource in PDM can play a more effective part of CAPP systematic function in current CAD application. Increasing CAPP systematically practical, professional and universal function has always been the main research of integrating PDM with CAPP.The fifth chapter introduces the details of author's independently implementing PDM project in Changsha CADSTAR information technology,Ltd. and the author's understanding and experience after taking part in several PDM projects. The expectation of enterprises' implementing PDM is to increase the efficiency of product designing, shorten the product outputting cycle and increase the enterprises' competitiveness in result, but the high failure rate make the enterprises and software companies have to reconsider the implementary method and key problems.
