摘　　要：收绕电缆引导棍的特征是其上有左、右旋头尾相连的交叉引导槽。引导槽与引导棍的两端不相通。迄今为止,引导槽都是在四轴加工中心或车铣中心上用成型刀铣出来。介绍了在车床上利用FANUC系统宏程序来实现以车代铣的一种引导槽加工新方法。对不锈钢材质和形状细长的引导棍,可采取分层车削、正确选用标准车刀和不断改进半成型非标准车刀等措施来减小车削过程中的振动。采用这种新方法与常用的用铣床加工的方法相比,效率提高4~5倍。The feature of guide rod winding cables is the crossing guide grooves with right connecting left thread end - to - end. There are not connections between guide rod and guide grooves on both ends. So far, guide grooves are milled on 4 - axis machining centers or turning - milling machining centers with forming cut- ters. Introduce a new method machining guide grooves realizing turning replacing milling on lathes using FANUC system macro program. For slender guide rod of stainless steel, vibration in turning can be re- duced by layered turning, selecting standard turning cutters correctly and improving semi -forming non - standard turning cutters continuously and so on. Comparing this new method with common methods on milling machines, the former＇ s efficiency can be increased by 4 -5 times.
