The Construction Of A Web-based, Dispersed Synergic Design And Manufacturing Platform

The constant changing market brings forward new and severe requirements on the current machine tool's manufacturing industry. The developing net technologies and advanced manufacturing mode enable the dispersed synergic work. In order to cater for the need of the modern manufacturing industry and improve the response status of the design and manufacturing industry, the research project on a web-based, dispersed synergic design and manufacturing of machine tools production was put forward. At first, the characteristics and requirements of services of the web-based, dispersed synergic design and manufacturing platform was analyzed. According to the result of the analysis, the structure of the system and resolving solution were provided as well as six key technologies such as virtual reality, parametric design, distributed technology, ASP technology, virtual assembly and modern manufacturing technology. After that, the model of the business logic and project management was established by using UML and Petri Net modeling utilities. Based on the requirement analysis of the system and the SQL Server database management technology, the web-based database was realized and the application layer of the database was also given. During the realization period of the prototype of the system, based on the DCOM/ActiveX distributed component technology and Solidworks API, the parametric design module was constructed and this in turn consummated the auto-development function of the dispersed synergic environment. After that, based on the virtual reality markup language, the dispersed synergic design environment was constructed by using ASP –server side programming technology and all kinds of real time communication tools such as netmeeting, whiteboard and chatting room. This environment composed acted as the main part of the whole system. The web-based, dispersed synergic design and manufacturing system was based on the canonical programming method and principle of system modeling, taking the practicability of the prototype as a start and providing a complete process control model. The interfaces of virtual assembly and remote machining were also given which would be a support of the later research works. The operation of the machine tools'development has proved that the system functioned well with high reliability. The web-based dispersed synergic design and manufacturing system is an attempt in the machine's design and manufacturing field. Some of its components (such as manufacturing module) still needs to be extended and further developed.
