湖南水利水电职业技术学院 Hunan Technical College of Water Resources and Hydro Power 毕业设计成果 Graduation practice achievement 设计项目名称自动化组合机床的PLC控制系统设计 姓 名： 彭建成 专 业： 机电设备维修与管理 班 级： 09级机电设备维修与管理一班 学 号： 200933010012 指导老师： 赵 楠 任务下达日期： 2011 年 11 月 20 日 设计完成日期： 2011 年 12 月 1 日 Abstract This article introduced that the PLC control system design of Automatic 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 development 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 the 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 we also introduced Fault diagnosis and exclusion of PLC control system and further summary fo the article. 【Key words】: PLC 、Mitsubishi FX series、combined machine tools 摘 要 本文介绍自动化组合机床的PLC控制系统设计，该系统具有自动化程度高，精度高等特点，在工业生产等领域有广泛应用。传统的组合机床采用继电器，精度低，可靠性不高，已不适合社会发展需要。随着PLC控制技术的迅速发展，以PLC为核心的组合机床控制系统已凸显出其优势。 本文首先介绍PLC和组合机床的历史与发展，并论述了组合机床的运动形式以及控制方式，接着对PLC控制系统的总体设计和程序的表达方式做了概述，然后确定PLC型号、分配I/O地址和外部配线，接着根据相关内容画出顺序功能图并利用FXGPWIN软件画出PLC梯形图。在文章的最后还介绍了PLC控制系统的故
