为方便加工零件上不同位置的非圆曲线，采用坐标系平移的方法，将给定非圆曲线表达式的原坐标系向数控车床建立的工件坐标系分别沿x，y轴进行平移，使两坐标系的坐标原点重合，再将待加工的非圆曲线方程转化为数控车床工件坐标系中的非圆曲线方程，最后只需针对数控车床工件坐标系中的非圆曲线方程进行粗车循环与宏程序联合编程，即可方便地实现零件加工。建立了加工不同位置非圆曲线宏程序编写模式。提出的坐标系平移方法，可方便地对不同位置的非圆曲线在建立数控车床工件坐标系中建立新的表达式方程，该方法数学计算简单，适用于各类非圆曲线的宏程序编写。

In order to manufacture non-circular curves in different positions on a mechanical component conveniently,a method of translating coordinate system is adopted to make the original coordinate system of non-circular curve expressions trans-lated to workpiece coordinate system established by CNC lathe along x and y axes respectively,make the coordinate origins of above-mentioned two coordinate systems coincided,convert original non-circular curve expressions into the new curve expres-sions of CNC lathe,and then make the combined programming of rough turning and macro program according to the new curve expressions to realize the workpiece machining. The macro programming mode of non-circular curve processing in different posi-tions was established. The method of coordinate system translation,proposed in this thesis,can make non-circular curves pro-cessing in different positions on a mechanical component easier to establish a new expressing expression in CNC workpiece coor-dinate system. The method is simple in mathematics,and suitable for macro programming of all kinds of non-circular curves.
