Cad/capp/cam Integration Methodology for the Remote Manufacture of Cylindrical Parts Though the Web

This paper describes a multiagent architecture for CAD/CAPP/CAM integration for the remote manufacturing of cylindrical parts using Internet, especially through the protocols associated with the World Wide Web. This methodology specifies the modules of the system, and how these modules interact with each other. The methodology is conceived starting from the modeling paradigm based on the synthesis of design features, in order to allow the integration of the design activities (CAD), process planning (CAPP) and manufacturing (CAM Planning and Execution). The procedure begins with the modeling of a part by features in a context of remote manufacturing using the Web as the communication means, in a client-server computer model. The system is conceived in a distributed environment of agents of interoperable pieces of software called Community of Manufacturing Agents, whose architecture is stratified in three levels: Design, Process Planning and Manufacturing. The flow of information among the three levels is accomplished through information encapsulation, being adopted the Knowledge Query and Manipulation Language (KQML) as the language pattern of messages among the agents.
