摘要
通过详细介绍G73指令在加工时的使用格式、各参数的意义、刀具循环路径、ΔI(X轴方向退刀距离)的应用公式和非圆曲线的宏程序模板,讲述了在数控车床上运用G73指令加工非圆曲线形状的工件的方法,对其他数控系统加工非圆曲线形状的工件有一定的参考价值。
Based on the form of G73 command code, the meaning of every parameter, AI of employ formulae （the distance of return in X - axis direction）, cutter circulation route and macro template of non - round curve, it describes a processing method for the non - round curve work piece on NC lathe. This method has important reference value to the other NC system in processing the non- round curve work piece.
