Development of a System Internet-based Collaborative Cad/capp/cam in a Context of E-manufacturing

This work presents a description of the implementation of the WebMachining methodology and system (http://WebMachining.AlvaresTech.com) developed in a context of e-Mfg and Concurrent Engineering, aiming at integrating CAD/CAPP/CAM for the remote manufacturing of cylindrical components through the Internet. The methodology and its implementation are conceived starting from the modelling paradigm based on synthesis of design features, in order to allow the integration among collaborative design (WebCADbyFeatures), generative process planning (WebCAPP) and manufacturing (WebTurning). The system is implemented in a distributed environment of agents (agents' community), and Knowledge Query and Manipulation Language (KQML) is adopted as the language for message exchange among the design, process planning and manufacturing agents.
