数控机床的PLC设计
摘要:随着信息化产业的高速发展,数控机床的功能日趋完善,数控机床取代普通机床已是一种必然的趋势,随着数控机床的发展,传统的继电器控制系统已经不能满足工业生产的需要,而可编程控制器(PLC)因其具有可靠性高,抗干扰能力强;功能强,性能价格比高;硬件配套齐全,用户使用方便,适应性强;编程方法简单易学等显著特点,已成为人们的首要选择。在此背景下,本文提出了数控机床的PLC设计思路。
本文描述了如今数控机床的基本组成、工作原理、分类及各自的特点。并且对数控机床中的PLC做了详细的介绍,把PLC在数控机床的工作过程,设计流程做了具体分析。然后以立式车床C5112B为例,描述了它的PLC设计过程,最后再介绍了PLC在数控机床上故障维修的一些方法。

PLC design of NC machine tools
Abstract: With the rapid development of information industry, the functions of numerical control machine tools are maturing. CNC machine tools has been replaced by ordinary is an inevitable trend, with the development C machine tools, the traditional relay control systems can not meet the industrial production needs. Programmable Logic Controller (PLC) because of its high reliability, strong anti-interference; feature strong, high cost performance; hardware package plete, the user easy to use, adaptable; programming easy to learn and other notable features has e the first choice. In this context, this paper presents design ideas C machine tool.
This paper describes the position , working principle, classification C machine tools and their characteristics. And on the NC machine tool in the PLC made a detailed introduction to the work of the PLC in the process C machine tools, to do a detailed analysis of the design process. Then vertical lathe C5112B, for example, describes its PLC design process, and finally introduces the PLC fault in the maintenance C machine tools on some of the ways.
