本文介绍应用在一个CNC机床控制系统中的数据采样轮廓插补算法——扩展的DDA法,这种算法具有结构简单、速度快、精度高、易于扩展到多坐标轴控制的特点。这种算法也适于移植到微型计算机数控系统中实现。
This paper introduces a data sampling contour interpolation algorithm - an extended DDA method used in a CNC machine control system. This algorithm has the characteristics of simple structure, high speed, high precision and easy expansion to multi-axis control. This algorithm is also suitable for porting to micro-computer numerical control system.
