摘　　要：分析了X62W万能铣床控制系统的工艺流程、主要功能及常见故障,针对其控制系统存在的线路复杂、可靠性差、故障率高等缺点,选用三菱FX3U-32MR为铣床控制系统核心,通过PLC的I/O地址分配布置,以及外部硬件接线和梯形图程序设计,完成铣床控制系统改造.实践证明改造后的铣床控制系统可靠、稳定,提高了企业的生产效率.After an analysis of the technological process, main functions and common failures of the X62Wmulti- functional milling machine control system, the paper upgraded the control system to solve the problems including complicated circuit, poor reliability and high failure rate, with Mitsubishi FX3U-32 MR as its core, by allocating the I/O addresses of PLC, wiring the external hardware lines, and designing the trapezoidal chart procedure. It is approved that the milling machine control system becomes reliable and stable after the alteration; and the production efficiency is improved.
