2、matic combined machine tool, this system has a high degree of automation and precision, and also be widely used in industrial production and other fields. The traditional combined machine tool uses the relays generally, the precision is low, the reliability is not high, did not meet the social devel

3、opment need. Along with the PLC control technologys rapidly expand, as the core combined machine tool has highlighted its superiority take PLC. This paper first introduced that PLC and the history and development of the combined machine tools, and emphatically expounds the structure, movement and th

4、e control mode of combined machine tools, then the composition of PLC is analyzed, besides these, the general arrangement of PLC control system and the presentation of program are also given an overview, then we confirm PLCs type, distribute I/O address and external wiring. According to the related content we draw sequential function chart and use FXGPWIN software to draw PLC ladder diagram. At the end of the article
