Abstract:Based on analysis about performance of a five-axis CNC machine, using the MATLAB simulink, this paper provided a control method which can realize the dynamic performance simulink of the servo system, thus we can achieve the high-speed and high-precision requirement of the servo control system. And taking the servo turn table of the five-axis CNC machine as the confirmation object, its speed-regulating system was analysed and optimized with the simulation analysis research. So the simulation system was verified and analyzed through simulation.
Key words:NC machine;five-axis machine;servo system;dynamic response;simulation model
