- 物理技术－会议论文 
A virtual machining system based on virtual manufacturing technique and NC machining technique for high precision grinding machine is developed in this paper, which can realize all processes from the establishment of NC procedure to grinding machining simulation. The virtual machining environment is built with OpenGL technique on the platform of Visual C++, and the geometric simulation and impact interference checking are realized by C++ language. The structure of machining simulation system and its function are proposed. According to grinding machine tool characteristic, appropriate machining path planning is designed. The research shows that the simulations are reliable to complete the virtual grinding machining of the product by checking machining ability, rationality of design, prediction manufacture circle, and promptly modifying design. The method provides the theoretical foundation and reference value of practical application for structure design of grinding machine.
