非圆曲线的双圆弧拟合及数控加工的程序编制

Research on Dual-arc Fit for Non-circular Curves and its CNC Programming

采用双圆弧逼近的方法,在允许加工误差下解决对于给定的任意非圆曲线的拟合问题。开发并且实现了一个针对非圆弧曲线的数控编程软件工具,其主要功能可以实现对任意给定的非圆曲线的双圆弧拟合及数控加工代码的生成。

This article applied the double-arc to approach the non-circular curves uses the way of error approximation,which can solve the arbitrary non-circular curve fitting problems under the permit of error approximation,meanwhile,develops and carries out a non-circular curve against CNC programming software tool. Its main function can be achieved on any given round of the generation of the fitting curve and NC code.
