本文阐述了数控中的最佳插补原理,这个原理的基本思想是使刀具在所有可能的走向中选取最好的一种走向,以使下一加工点离所要加工的曲线最近,从而使插补偏差最小。我们称这种方法为最小误差法。 现把最小误差法与逐点比较法的加工轨迹加以比较。图1中a)和b)分别为逐点比较法和最 This paper describes the best interpolation principle in NC. The basic idea of ​​this principle is to make the tool choose the best one among all possible directions so that the next machining point is the closest to the curve to be machined, so that the interpolation Make up the smallest deviation. We call this method the minimum error method. Now the minimum error method and point by point comparison of the processing path to be compared. Figure 1, a) and b), respectively, for the point by point comparison and the most
