Development of Web-based CAM system

In this paper, we present the methods to develop a Web-based CAM system that is capable to dynamically simulate machining processes in solid graphics form through the Internet. Methods include the virtual reality modeling language (VRML) structure to represent the machined workpieces progressively on Web, the definition and storage of workpiece information upon the request of users, the CORBA-based interpretation of NC part programs, and algorithms for efficient machining simulation. Based on these methods, an Internet-based CAM system is implemented at http://isd.korea.ac.kr. Using the Web-based CAM system, public users can simulate machining processes by for their own NC part programs.
