The Applied Research of Four Polynomial Acceleration and Deceleration Control Method in Multi-axis DSP Motion Controller

In traditional NC systems, the linear, index and S curve acceleration and deceleration control methods exist lots of problems that jerk is discontinuous or algorithm is too complex, seeking a more superior acceleration and deceleration control method to make up these shortages is needed. In this paper, the Four polynomial acceleration and deceleration control method is researched further, some contrast experiments have been done on NC terrace which is based on 32 bit floating point multi-axis DSP motion controller, and the superiority of this method and the practicability in NC field are analysed by processing two hemispheres with H600 CNC engraving and milling machine.
