摘 要
日本三菱公司的FX2N系列PLC是一种性价比高的小型PLC，FX2N系列是FX家族中最先进的系列，最大范围地包容了标准特点、执行速度更快、通讯功能更齐全，为工厂自动化应用提供最大的灵活性和控制能力。
该机床是用三菱FX2N可编程控制器控制，专门加工箱体两侧的。其加工方法是先按下启动按钮，夹紧装置将被加工工件夹紧，夹紧后发出信号，再有左、右动力头同时快进，并同时启动主轴，到达工件附件，动力头快进转为工进加工，加工完毕后，左、右动力头暂停2s后分别快速退回原位，夹紧装置松开被加工工件，同时主轴停止。最终，完成箱体工件的加工。
该机床的工作流程为顺序控制，用步进指令实现控制，这样就使的机床在控制上更加的简化，也便于操作。

ABSTRACT
Japan's mitsubishi FX2N series PLC is a kind of high cost performance, small PLC FX2N series is the most advanced in the family of FX series, the maximum range tolerance standard features, execute faster, more complete communication function, for factory automation applications to provide maximum flexibility and control ability.
This machine is with mitsubishi FX2N programmable controller control, special processing on either side of the box body. Its processing method is to press the start button, the clamping device will be processed workpiece clamping, signal after clamping, have left and right power head fast forward at the same time, and start the spindle at the same time, reach the artifacts accessories, power head fast-forward to work into the processing, the processing is completed, left and right head suspended after 2 s quickly returned to the in situ, respectively, to the release of processed workpiece clamping device, spindle stop at the same time. In the end, the finish machining of enclosure.
Working process of the machine tool for sequence control, step by step instruction is used to implement control, thus make the machine more simplified in terms of control, also facilitate the operation.
