| Abstract: | Numerically controlled machining is the high quality and high efficiency machining method for free surface. Generating non-interface over-cutting cutter traces is the key of numerically controlled machining technology of free surfaces.With development of high -speed machining technology, cutter traces generated by high-speed machining tool are become more and more important. In this paper, the key technology, machining simulation during cutter traces generated and programming of numerically controlled machining of free surfaces are summarized. Current state and deficiency of commercial systems are analyzed. Finally, the key technology and tactics of free surface CAPP are discussed. |
