Aimming at mostly S-shaped feed-rate planning, constant jerk as a jump will cause the compact and vibration of machine tool, this paper presented a blended feed-rate planning algorithm based on continuous jerk. The machining trajectory was segmented firstly, then feed-rate planning with continuous jerk was implemented according to the length, feed-rate of the start and the end of each segment, the period was equal respectively.The expression was the same for jerk, acceleration and feed-rate for increasing acceleration and reducing acceleration phase. Increasing deceleration and reducing deceleration phase, in addition analytical expression is simple which is computed efficiently, and meet real-time requirements. The simulation results show this algorithm is feasible.
