摘　　要：本文针对金相取样的特殊要求,对金相试样切割工艺进行了研究,采用PLC和单片机相结合的控制方式,为该型金相式样切割机设计了控制系统。控制系统以OMRON CPM2A PLC为核心,AT89C52单片机作显示、输入模块,二者进行串行通信。PLC集中完成数据处理和控制任务,单片机完成参数设定和显示的功能。According to the special requirements for the metallographic sampling, the cutting methods of the metallographic sample were studied, by adopting the way of the combination of PLC and SCM, a control system of the metallographic sample cutting machine was designed in this paper. As far as the control system is concerned, the heart of the control system is OMRON CPM2A PLC, the single-chip Microcomputer of AT89C52 which serially communicates with PLC is used for display and input .PLC dedicates itself to data processing and controlling, the functions of the parameters setting and display are completed by the single-chip Microcomputer .
