一、现状 近年来我国企业的数控机床占有率逐年上升,在大中企业已有较多的使用,在中小企业甚至个体企业中也普遍开始使用。在这些数控机床中,除少量机床以FMS模式集成使用外,大都处于单机运行状态,并且相当部分处于使用效率不高、管理方式落后的状态。 I. Current situation In recent years, the occupation rate of CNC machine tools of Chinese enterprises has been increasing year by year. There have been more use in large and medium-sized enterprises, and they are commonly used in small and medium-sized enterprises and even individual enterprises. Among these CNC machine tools, except for a small number of machine tools that are integrated and used in FMS mode, most of them are in a stand-alone operation state, and a considerable part of them are in a state where the use efficiency is not high and the management method is behind.
