Control of the process of ACC/DEC (Acceleration/Deceleration) is one of most complicated problems in CNC system development. With the increase of acceleration and velocity in high-speed, high-precision CNC system, discontinuousness of acceleration will result in vibration, impact and debasing of position accuracy. The excellent ACC/ DEC control can solve these problems and improve the positioning precision. In this paper, S curve ACC/DEC algorithm is deeply studied, through comparison with other algorithms; its proved to be an efficient way in advanced CNC system. Usually, such kind of algorithm requires high-speed processor. However realization based on SCM (Single Chip Machine) is proposed in this paper. Through simulation, the result shows that the algorithm works well. Finally practical tests are carried out in Panasonic Minas A5 servo motor which indicates the control system is effective and accuracy.
