A kind of real-time collision-proof method of Digit Control Machine Tool

The present invention discloses and achieves a kind of relevant Digit Control Machine Tool real-time collision-proof method weak to digital control system; by Digit Control Machine Tool three-dimensional processing on real-time emulate and collision avoidance system gather digital control system signal of interest and in software system predictive algorithm process signal of interest rear drive Virtual Numerical Control Machine Tools emulate; the illegal collision occurred in operator's operating numerical control lathe or the course of processing or interference are carried out estimating emulation and carrying out alarm, returns digital control system stopping signal and carry out lathe protection.
