实现两轴联动的逐点比较法-直线插补的改进算法

A New Point-by-point Comparison Method of Linear Interpolation to Realize Two-axis

逐点比较法是轮廓插补算法之一,曾在数控机床中被广泛采用,但由于它存在不能实现两轴联动的缺点,限制了其应用。本文提出了一种改进的逐点比较法,在保持其原有优点的基础上,克服它存在的缺点,不仅实现了两轴联动,并在一定程度上提高了插补精度。

Point-by-point Comparison interpolation is one method of the contour interpolation algorithms ,ever used widely in CNC machine tools ,but its being not to realize two-axis limits its application .In this paper , A new Point-by-point Comparison Method of Linear Interpolation is put forward ,and this new algorithm not only overcomes it disadvantage and realize two-axis, but also improves the accuracy of the interpolation to some extent, While maintaining its original merits.
