针对极坐标系下的三维曲线加工，提出了一种新的刀具半径补偿刀位轨迹生成方法。提出了一种由干涉修正、根切区域避免和初始无干涉刀轨生成三部分组成的算法。首先介绍了鞋楦的数控仿形铣削加工数据。除了理论分析，该方法的可行性是通过加工鞋楦上的仿形铣床控制与内部开发的开放式数控系统。该算法对空间曲线车削加工具有很强的实用性。
A new tool path generation method is presented for tool radius compensation to deal with 3D curves machining on polar coordinates. An algorithm is suggested that consists of interference correcting, undercut region avoiding, and initial interference-free tool path generating. At the beginning, the numerical copy-milling machining data of the shoe last is introduced. Aside from a theoretical analysis, the feasibility of the method is demonstrated by machining a shoe last on the copy-milling machine controlled with an in-house-developed open architecture CNC. This algorithm is very practical for the space curve turning machining.
