| Abstract: | A feedrate programming algoritnm adapted to all kinds of spline interpolation（paramet- ric spline curve, B6zier curve, B - spline curve） has been proposed. Based on the assurance of the machining precision, a speedcontrol buffer with look -ahead function is set to process the interpolation acceleration and deceleration. The algorithm has improved the interpolation feedrate curve,and satisfied the acceleration and deceleration ability of the machine. |
