平面曲线的近似等误差双圆弧拟合及应用

Biarc and approximate equal-error fitting method of planar curve and its application

根据快走丝线切割数控加工的特点 ,提出一种平面轮廓曲线的近似等误差双圆弧拟合方法 ,给出曲线拟合的计算机自动编程算法 ,介绍其在线切割自动编程系统中的应用。

A planar curve fitting method with biarc and equal-error approximation has been developed according to the features of WEDM-HS CNC Machining.The algorithm of curve fitting has been put forward,and its application to the auto programming in wire cut is introduced.
