为提供虚拟的加工环境和验证工艺设计的正确性，对切削加工过程的计算机仿真方法进行了研究，以OpenGL作为图形支持系统，用VC++开发了切削加工仿真系统。该系统实现了车、铣、刨、磨等多种加工方式的仿真，可对刀具运动和材料切出情况进行实时监控，且可通过工艺参数(如切削速度、进刀量等)对切削过程进行控制，并能自动计算和优化切削时间、成本等参数。系统界面友好，操作方便，运行可靠，能有效地帮助工艺人员对整个加工过程进行直观的评估和验证。
To provide a virtual manufacturing environment and verify machining process, research on the simulation method for machining process on computer is conducted in the paper. A simulation system for machining process is developed based on OpenGL by Visual C++6.0. In the system, the simulation of 17 kinds of often used machining, including turning, milling, planning, grinding, etc., is realized. The animation of cutting tools movement and the material removing of part can be controlled by some process parameters, such as cutting speed and cutting path. The time and cost of machining can be computed automatically and optimized. The system is user-friendly and ease-to-use and can run rightly and effectively.
