摘　　要：利用虚拟现实建模语言,探讨了建设虚拟机械加工实验室的若干关键技术。提出了四层式的框架结构,以应用功能为模块对逻辑流程做了规划。应用Java Script和Java Applet实现与VRML场景的通信,解决了数据交互问题;设计了接触检测器,实现用户自由选择视点功能;设计了邻近检测器,实现场景导航时的场景切换功能。以钻床夹具为例,阐述了虚拟机械加工实验室的应用功能,通过可视化和互动的方式使得工艺课程教学更加方便和接近车间实际。The key technologies of the construction of virtual machining laboratory are discussed based on virtual reality modeling language. A four-layer frame is put forward. The logical process is planned with function modules. The communication with the VRML scene is achieved by adopting Java Script and Java Applet to solve the problem of data interaction. The touch sensor is designed to realize the function which is used to freely choose viewpoints by users and the proximity sensor is designed to realize the function of scene switching in scene navigation. A drilling fixture is taken as an example to expound the application of the virtual machining laboratory. The process teaching courses are made more convenient and closer to the actual workshop by means of the visualization and interactive.
