多坐标轴广义直线插补的简易算法

A simple algorithm for multi-axes general linear interpolation

提出了一种用于多坐标轴广义直线插补的简易算法。以数值积分法 ( DDA)直线插补算法为基础 ,设计了一个插补决策算法来决定是否进行插补计算 ,从而完全消除了不产生进给的插补计算过程。简易算法不但插补效果好于 DDA,而且计算量明显少于 DDA。它还能够做到多坐标轴同时进给 。

A simple algorithm for multi axes general linear interpolation is introduced. Based on the DDA(digital differential analyzer) linear interpolation, a decision algorithm is designed to decide if the interpolation is carried out or not. Therefore, the DDA processes without output are completely eliminated. With this algorithm, not only is the effect better than that of the DDA , but also the interpolation computation is much less than that of the latter.
