摘　　要：针对多特征轴类零件加工中的刀具补偿问题,采用局部补偿方式,避免刀具补偿时零件的连接特征加工精度相互影响。以实例分析该方法在FANUC-0iT数控系统中的应用,结果表明:加工多特征轴类零件时,连接特征的加工精度得到了保证,零件整体加工精度得到了提高。Aiming at the problem of tool compensation in the processing of multi-feature parts,the local compensation method was adopted to avoid the mutual influence of the machining accuracy of the connection features of parts when the tool was compensated.An example was given to analyze the application of this method in FANUC-0iT CNC system.The results show that the machining accuracy of the connection features of the multi-feature shaft part is guaranteed and the overall machining accuracy of the parts is improved.
