Research On The Machine Tool Product Management System In The Networked Manufacturing Environments

The fast development and abroad applications of network technology has greatly changed the people's production and life styles, as well as the influence in the operation mode of manufactures. Networked Manufacturing (NM) emphasizes the collaboration among the enterprises and resources shares in the scope of society; it is able to make the product design and manufacture in low cost and high speed. In order to improve the response status of the design and manufacturing, and speed up the process of information-based in our machine tools industry, the research based on machine tools product data management in the NM environments was put forward.At first, the PDM characteristics in the NM environments were analyzed. Based on the product data requirement of machine tools industry, the system structure and resolving solution were provided, and combined with the technology of Object-Oriented analysis, the function constitution of PDM system based on project management was put forward, then using UML, the model of the system's function module were set up. After that, the data layer and the data interface layer of the prototype system were designed, and then the database design scheme and the method of database application layer of the system were provided.The problem of dynamic alliance construction was an initial problem in the research of the machine tools product data management based on the NM environments. This paper chiefly focused the topics on discussing the problem of partner selection and partner evaluation. Using the way of project recruit/ bid set up dynamic alliance, the model of partner selection was built and the factors evaluation of hierarchy were designed, then by using the fuzzy synthesis evaluation, the best choice from latency partners was build up.The machine tools product data system was based on the canonical programming method and principle of system modeling, taking J2EE as the network development technology, and was centered in project management. Choosing the application of FTDK5616 sculpture machine as an example, and gathered with project lifecycle and personnel right management, the paper introduced the realization of the system, and then verified all these theories and key technologies of the system.Basing on the network technology, the machine tools product data system can meet the requirements of machine tool industry in networked manufacturing environments; make lower cost of design and manufacture; shorten the period of product developing. It can also improve the economic performance of the business enterprise, and support for the designing; manufacturing and managing of the machine tool industry in different areas.
