The virtual CNC lathe machining simulation study . The object - oriented design method based on analysis of virtual NC machine tool system structure , the Visual C 6.0 platform , the research and development of the virtual CNC lathe machining simulation system based on OpenGL interactive control to achieve at different speed , feed rate , CNC lathe cutting process dynamic simulation NC code conditions . This article uses OpenGL technology , the use of which provides powerful 3D graphics editing features , combined with object-oriented modeling approach , 3D machining simulation environment . To achieve the interactive control by using the MFC framework to create a three - dimensional simulation system and friendly man-machine interface ; tool library is created to accommodate the needs of different parts of the processing ; design the NC code translator module by using the OpenGL drawing functions to drive lathe action; modeling method , is more conducive to the bottom of the development of simulation system ; design refinement of the rough and clever cutting algorithm to reduce the amount of background calculation , improve system speed to achieve a real-time dynamic simulation of the process . Meanwhile, the in machining simulation process , using OpenGL double buffer technology , accelerated graphics display , to avoid the flickering of the screen , to process animation more continuity , more real-time processing of the workpiece forming process . Run the test system : The system has good real-time , interactive , scalability , and three-dimensional graphics display capabilities to effectively verify the correctness of the program , help to reduce the inefficiencies caused by the trial cutting method checks high consumption , improve CNC the equipment production efficiency .
