The history and development of PLC and bination of machine tool are introduced first, and focuses on bination of machine tool structure and form of movement and control method, and then position and structure of PLC are analyzed, and the overall design and program of PLC control system of expression are summarized, and then according to the related content to draw the sequential function chart and the use of FX-2N to draw the PLC ladder diagram. At the end of the article also introduces the PLC control system installation and maintenance and further summarizes the thesis. Keywords: shell of the gearbox, combination machine, programmable logic controller (PLC); control system 广西工学院鹿山学院本科生毕业设计(论文) IV 目录摘要...............................................................................................
