為提供虛擬的加工環境和驗證工藝設計的正確性，對切削加工過程的計算機仿真方法進行了研究，以OpenGL作為圖形支持系統，用VC++開發了切削加工仿真系統。該系統實現了車、銑、刨、磨等多種加工方式的仿真，可對刀具運動和材料切出情況進行實時監控，且可通過工藝參數(如切削速度、進刀量等)對切削過程進行控制，并能自動計算和優化切削時間、成本等參數。系統界面友好，操作方便，運行可靠，能有效地幫助工藝人員對整個加工過程進行直觀的評估和驗證。

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.
