摘要
综合比较多种非圆曲线逼近拟合方法,等误差曲率圆法是最佳方法。文中对等误差曲率圆法进行了数学描述,提出了可行的拟合算法,并基于该算法编制出程序流程图。利用该程序流程图,为数控编程人员编制非圆曲线程序提供了思路,具有一定应用价值。
According to the comparison of several non-circular curve approximation fitting methods, equal-error curvature circle method which is described by mathematics algorithm in this paper is the best method. The feasible fitting method is put forward to build flow chart for programming the non-circular curve, which can provide reference for CNC programmer.
