Abstact:The computer graphic simulation of NC cutting machining which can verify the cutting process accurately and prevent accidents, is widely used. This paper studies the data structures and algorithms needed during the development of system. Builds up the mathematic model of work piece and tools, according to the machining features milling, designs the simulation algorithm, completes the tool track verification and cutting process simulation with the support of OpenGL and Open Inventor. Finally, it uses a practical example to provethe simulation module is correct on the NC machining process simulation.
Key words:numerical control processing;graphic simulation;processing algorithm
