Abstract:  Aiming at the previous literature focusing on individual method of acceleration and deceleration, several major acceleration and deceleration methods on stepper motor were comparatively analyzed and specific mathematical descriptions were presented. Based on the frequency characteristics of stepper motor, the advantages and disadvantages of each method were pointed out. Then, the linear and Scurve were indepth studied, and Scurve was applied in  own CNC system, and good results has been achieved. The results indicate that several acceleration and deceleration methods have their own advantages, and they can be selected according to different occasion.
Key words: computer numerical control(CNC) system; stepper motor; acceleration and deceleration control
