Study on machining simulation system of virtual NC lathe based on OpenGL

On the basis of analyzing system structure of virtual NC lathes,an OpenGL-based machining simulation system of virtual NC lathe is designed using Visual C++ 6.0 as the development platform.The machining process dynamic simulation of NC lathe is achieved under various conditions such as different rotation speed,different feeding speed and different NC codes.The proposed system features good in real time,interaction,expansibility and display of 3D graphics.Also,the correctness of NC codes could be effectively validated,which is helpful for reducing the high consumption and low efficiency caused by trial cutting method and improving the production efficiency of NC facilities.The numerical control machining process is simulated through Computer Graphics and VR technology which may save cost,avoid risks and carry on the training of NC technology.
