列表点曲线拟合程序在整个运行过程中除了要进行必要的数据输入操作和选择车床与铣床之用操作外,均不要另外操作,这将方便操作者。经过计算机前段程序的计算,求得了一批园弧的半径、园心和切点数据并处理为G代码但这批数据所描绘的曲线图形要到数控机床输入指令操作后,才能得以最后验证,但为了保 Point-point curve fitting program in the entire process of operation in addition to the necessary data input operation and the choice of lathe and milling machine with the operation, do not operate separately, which will facilitate the operator. After calculation of the computer front-end program, a number of radius, center of circle and tangent point data of circular arc arc obtained and processed into G code. However, the curve graph drawn by this batch of data can not be verified until input instruction operation of numerical control machine tool, But to protect
