Abstract

With the development of high-speed and high-precision machining, S-curve acceleration and deceleration planning has attached considerable attention. Aiming at the character of non-linearity of motion control of parallel machine tools, a hybrid S-curve acceleration and deceleration speed planning method, which is planned in workspace and evaluated in joint space, is proposed in this paper. The machining efficiency is improved by using the strategy between adjacent micro-linear segments. The simulation results show that the S-curve acceleration and deceleration method is more advantageous to the stability of the system than the linear acceleration and deceleration method.
