To improve the processing speed,an improved five-segment S-curve acceleration and deceleration algorithm based on the transition arc is proposed. It has five movement stages： and makes jerk continuously linear change in respective segments,enabling velocity and acceleration continuously change; The smooth transition model based on arc can enable the machine transfer in high speed between the micro segments,improve the efficiency of processing and reduce the impact on machine as the same time. Experimental results showthat the algorithm enables the machine drive in higher speed between the switching,extending the life of the machine tools,improving flexibility of the system.
