The mathematical model of a NC machine tool feed drive system is set up according to the theory of mechanical dynamics theorem. The simulation model of applying motor to driving the machine tool feed drive system is built up by dynamic simulation tool Simulink and the simulation curve lines of reflecting the system performances are acquired. According to the simulation model, the effect of nonlinear friction on system performances is analyzed, and the measures of improving the system performances are given. Therefore the theoretical basis is given for design and performances improvement of mechanical drive system.
