Research of NC Milling Simulation Based on OpenGL

Through examining the exactness of NC code, the system makes the orbit of the cutter. For the NC milling machining, building the triangular meshes according to Delaunay rule on the top-surface of the roughcast, cutting the roughcast step by step with the method that calculate the intersection between the discrete vector and cutter swept volume,and carry out the machining process simulation with OpenGL.
