The Research And Application Of Product Data Communion And Exchange Based On The STEP Standard

With the development of advanced manufacture technology, CAD/CAM system has come to be accepted by people. Therefore, the demand of product data exchange criterion will be needed in the manufacture, and the standard of STEP becomes one of the choices. At the same time, with the scope of engineering application becoming wider, the depth of application has been increasing. In the course of application many technologies need to be researched.Therefore, on the basis of investigating the STEP standard, the paper analyses the role of STEP standard plays in the customer customizing system and the way of integrating PDM system with customer customizing system. Simultaneity, the paper comes to compare the ways that STEP standard works, chooses the best way to implement object and develops a system which runs on the internet with Java technology. According to the research result, the paper builds the whole structure which is with the core of customer customizing system and PDM system to increase the productivity.The writer researched the way of STEP standard applying in the customer customizing system and establishes the research goal of product parameter design and data exchange. According to the goal, the paper designs the customer customizing system which meets the need that the customer can join the course of product design.As one part of all researches, the paper studies how to build the distributed and integrated system and puts forward the corresponding resolutions, building the relation bridge of PDM system and customer customizing system. On the basis of it, the paper finally integrates the PDM system with the customer customizing system.At last, the paper summarizes the all researches, builds the whole system's structure and finishes some modules of the system.
