列表点曲线数控加工方法的分析与研究

Research on the CNC Machining Methods of the Discrete Data Curve

分析和研究了列表点曲线的数控加工问题 ,提出了先以三次参数样条进行插值 ,再用双圆弧拟合的方法。实例证明 :该方法拟合后的曲线光顺 ,偏差较小 ,并且算法简单。

Studying on the CNC machining of the discrete data curve, this paper presents that the discrete data curve was fitted by biarc after interpolating by cubic parameter spline. Theexample shows that machining curve is smooth and precise.
