為提供虛擬的加工環(huán)境和驗(yàn)證工藝設(shè)計(jì)的正確性，對切削加工過程的計(jì)算機(jī)仿真方法進(jìn)行了研究，以O(shè)penGL作為圖形支持系統(tǒng)，用VC++開發(fā)了切削加工仿真系統(tǒng)。該系統(tǒng)實(shí)現(xiàn)了車、銑、刨、磨等多種加工方式的仿真，可對刀具運(yùn)動(dòng)和材料切出情況進(jìn)行實(shí)時(shí)監(jiān)控，且可通過工藝參數(shù)(如切削速度、進(jìn)刀量等)對切削過程進(jìn)行控制，并能自動(dòng)計(jì)算和優(yōu)化切削時(shí)間、成本等參數(shù)。系統(tǒng)界面友好，操作方便，運(yùn)行可靠，能有效地幫助工藝人員對整個(gè)加工過程進(jìn)行直觀的評估和驗(yàn)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.
