A DDA interpolator is a typical hardware interpolator and was used for a long time, but is not much used in today’s CNC systems. In modern CNC systems, a software DDA interpolator is used, where the algorithm of the hardware DDA interpolator is

CNC系统进行直线插补运动的算法，值得大家借鉴，理解基本原理-CNC motion system, linear interpolation algorithm, it is worth all learn to understand the basic principles

这是一些研究数控机床插值算法的论文，很有参考价值。-This is some of the papers of CNC machine tools interpolation algorithm, great reference value.
