摘  要
 
 数控机床种类繁多、型号多种多样，可分为数控车床、铣床、镗床、磨床。本文介绍PLC在M1432A型万能外圆磨床控制系统的设计。由于可编程控制器(PLC)是专为在工业环境下应用而设计的一种工业控制计算机，具有抗干扰能力强、可靠性极高、体积小、是实现机电一体化的理想控制装置等显著优点，因此通过实践与深入研究，本文提出了利用PLC控制步进电机实现数控系统点位控制功能的有关见解与方法，介绍了控制系统研制中需要认识与解决的若干问题，给出了控制系统方案及软硬件结构的设计思路，对于工矿企业实现相关机床改造具有较高的应用与参考价值。

Abstract

 The numerically-controlled machine tool great variety, the model are many and varied, may divide into the numerical control lathe, the milling machine, the boring lathe, the grinder. This article introduces PLC in the M1432A multi-purpose cylindrical grinder control system's design. Because programmable controller (PLC) is specially for one industrial control computer which applies under the industry environment designs, has the antijamming ability to be strong, the reliability is high, the volume slightly, is extremely realizes the integration of machinery ideal control device and so on remarkable merit, therefore through the practice and the deep research, this article proposed step-by-steps the electrical machinery using the PLC control to realize the numerical control system position control function related opinion and the method, introduced in the control system development needs to know certain questions which and to solve, has given the control system plan and the software and hardware structure design mentality, realizes the related engine bed transformation regarding the Industrial and mining establishment to have the high application and the reference value.
