Copy of cutting of numerical control lathe studies really

1. Introductive
　　
Allah of copy of fictitious treatment process should include geometry to emulate emulate with physics, if pursue,1 is shown. Geometry emulates the influence that takes no account of element of physics of etc of force of cutting parameter, cutting, emulate cutting tool only - the motion of workpiece geometry body. All sorts of works that can complete through translating numerical control code to be machined with imitate turning if the circle outside treatment, end panel, pour horn, whorl, curve to wait come the rationality of NC code and validity check test and verify to whether have collision, interference, the machine tool loss that because the program is wrong,be eliminated and causes, clamping apparatus is destroyed reach the phenomenon such as cutting tool attaint. Current emulation system undertakes geometry is emulated only mostly, be opposite namely knife the interference of orbit, workpiece and cutting tool undertakes desired result wait, emulate geometry what be united in wedlock with physical copy truth less.

Of cutting process mechanical emulate a kind when belong to physics to emulate. Cutting force is computation clamping apparatus of cutting tool of cutting power, choice, design and in establishing the link such as craft cannot little data, to affirmatory and reasonable metallic cutting dosage, optimize the geometrical parameter of cutting tool, have very important sense; It is affecting the generation of heat in metal cutting directly, affecting cutting tool to wear away further, cutting tool durability and already machined exterior quality. the analysis getting power of workpiece real time application is among fictitious treatment process, not only can the change getting power that the parameter change that imitate demonstrates to wait as a result of workpiece, cutting tool brings, still can undertake be adjustmented in time, the help chooses the most appropriate treatment parameter.
