The Remote Network-based Rapid Prototyping System

Rapid Prototyping(RP) Technology is an important breakthrough in manufacturing technology for twenty years. The influence of Rapid Prototyping technology is equal in value to the emergence of NC technology. As the RP system integrates the mechanical technology,CAD,NC,layer engineering and material science ,etc, we can accurately transform our model in mind into a real prototype or directly produce component part or dies. So that, the research period of products will be sharply shortened. The combination of RP and Web technology will promote the development and spreading in RP technology and shorten manufacturing period. In this article ,we study the remote RP service system based on Web around a RP manufacturing center.The dissertation put emphasis on the key technique of implementation about remote RP service system based on Web. The main contents include:1) Through studying the service function of the remote RP manufacturing center platform, The whole integrated frame is set up and respective functional modules are designed, three-layer browser/server model is promoted and realized.2) Studied the key software for Web service such as ASP,COM,ActiveX technology and database system, analyzed their work method and development technology.3) According to the evaluating indicator of RP process, put forward a multi-attributes evaluation system process selection algorithm. On the Windows operating system and IIS platform, the remote inquiry service of the RP machining parameters has been realized. by using ASP,ADO and SQL technology.4) Studied the STL file form and defects, established the topologic information among point,line and facet, designed a algorithm for repairing the STL file defects.5) Discussed watching the STL three dimensional model on the Web by using openGl and ActiveX control technology, designed the main function of the program.6) Analyzed and designed the system database, accomplished the database structure, constructed the RP service platform, realized some functions of the system. Based on the techniques mentioned above, the platform of the remote RP service...
