基于现代控制平台高精度切割一般函数曲线方法的研究

The Study on Accurately Cutting Curves Based on the Modern Control Platform

直接函数运算法是以基准变量和基准参量为进给运算推进基准、以曲线方程为进给决策运算基础对非圆函数曲线的切割而实施的直接进给控制策略。

The direct calculation method which uses reference variable and reference parameter as the advance norm for feed calculation and takes curve function as the calculation base of the feed decision making is the direct feed control tactics for cutting non circle curves. In this paper, the basic theory of the direct calculation method and the technique for adding offset to all kinds of curves are studied in detail.
