Research on smooth transition control algorithm for continuous path

When machining complex counters, the conventional PTP control causes jitter of the machine, reduces machining efficiency due to the frequent changes of feed rate. A new control algorithm was put forward to realize smooth transition for continuous path. The existence of interpolation discretization was pointed out. The execution efficiency of two single-period transition solution was compared. In order to realize the smooth transition of line and arc, this paper compared the instruction cycle of radical formula and approximation method. The simulation result indicated that, while ensuring the precision of contour error, the continuous interpolation was realized, which effectively improved the machining efficiency.
