中文摘要：

复杂运动轨迹尤其是非均匀有理B样条（NURBS）曲线插补技术,一直是高性能数控系统研究领域的热点。从样条曲线构造机理出发,分析了双圆弧逼近曲线基本原则,提出了一种构建NURBS曲线插补的技术方案。分析了NURBS曲线数学理论基础、双圆弧基本数值算法、参数曲线插补速度波动抑制若干策略。验证实验证明了该技术方案的可行性。

英文摘要：

As the key technology of modern numerical control system,complex trajectory NURBS interpolation technology catches close attentions from the manufacturing industry and academia all along.This paper presented a new method building NURBS interpolation technology platform from the viewpoint of theoretical deduction of NURBS mathematic relation and numerical algorithm of biarc.And some numerical methods to reduce speed variation were investigated to fulfill develop purpose.Finally,the experiments were carried out to verify the research feasibility.
