摘要
提出一种用工业控制机的汇编语言实现的空间任意圆弧的ＮＣ插补算法，该算法利用ＤＯＡ算法的原理，并在此基础上予以扩展，能实现三轴联动加工，它的运算速度快，精度高，用该算法加工空间曲面取得了满意的效果。
A new extended DDA interpolation algorithm for any space circular arc is proposed in this paper,whigh is very useful for complex curved surface machining.Its basic thought is to resolve tangent velocity on space circular arc into components along each axis. So generalized extended DDA interpolation for any space circular arc is deduced. At last machining result are presented, which shows that this algorithm is powerful to machine comple curved surfaces.
