| 摘 要： | 基于直接函数法的圆弧插补算法能够有效提高插补精度,但是在终点判别时需要对两个轴向的步数进行计算,时间较长.在对长轴终点判别方法进行研究的基础上,提出了一种改进的直接函数法的圆弧插补算法.以每步插补的连续前进轴为长轴,并以在长轴上的插补步数为判断基准,对插补点是否到达终点作出判断.该方法要求不同卦限圆弧对应不同长轴.该算...

| Abstract: | Direct function based on circular interpolation algorithm can effectively improve the interpolation precision,however,it takes a long time to calculate each axis steps for discriminating end-point.Based on the research on the long axis end-point discrimination,an improved direct function algorithm for circular interpolation is proposed.Considering the continuously move forward steps of each step interpolation as long axis,the algorithm judges whether the interpolation point reaches the end-point by using th... |
