摘要
在圆弧插补的基础上推导出了抛物线时间分割插补算法。即首先求出圆弧上插补点的坐标,再用简单的计算公式转换为相应的抛物线上插补点的坐标。计算实例表明,使用这个方法可以缩短插补计算时间,实时性好,插补精度高,进给速度波动范围小。
Time dividing method of parabolic interpolation has been derived based on arc interpolation. First of all, the coordinates of interpolation point on arc are found, and then the corresponding ones on parabolic are obtained with a simple formula. The simulation calculating shows that, the computing time can be shortened, the real-time operation is good, the interpolation accuracy is higher, and the feed speed is even.
