Research on Machining Simulation for Web-Based Virtual Machine Tool

With the development of computer technology and network technology,Virtual Manufacturing Technology(VMT) has becoming the new frontier of the manufacturing research.The paper has researched on the key technologies of NC machining simulation based on Network.On the basis of analyzing the interaction between VRML and JavaScript,material removal algorithm,collision detection algorithm and NC codes compile,the paper presents a simulation system for Web-based virtual machine tool,which can realize machine tool 3D view,motion simulation and virtual assembly under Web environment.The surface processing simulation developed by OpenGL is embedded in the system.Users only need to install the browser plug-in to access the system.Compared with other commercial CAM systems,the system has the features of small files and easy modular expansion.
