Feed servo system model of CAK3665 NC machine tool was constructed. Simulation model of the sys-tem was built up based on MATLAB/Simulink, and simulation curves of responding system performances were ac-quired. The effect of backlash and dead zonenonlinear on system performances was analyzed, and the measures of im-proving the system performances were put forward. The paper has supplied effective theoretical reference for design, parameters choice and performances improvement of NC machine tool feed servo system.
