文档介绍：摘要
随着时代的发展,科技的日新月异,数控技术的应用范围日益扩大,数控机床及其系统己成为现代化机器制造业中不可缺少的组成部分。鉴于我国机床拥有量大、工业生产规模小的特点,突出的任务是用较少的资金迅速改变机械工业落后的生产面貌,使之尽可能地提高自动化程度,保证加工质量,减轻劳动强度,提高经济效益。而实现这一任务的有效的、基本的途径就是普及应用经济型数控,并对原有的机床进行数控改造。
数控机床作为机电一体化的典型产品,在机械制造业中发挥着巨大的作用,很好地解决了现代机械制造中结构复杂、精密、批量小、多变零件的加工问题,且能稳定产品的加工质量,大幅度地提高生产效率。工业设备对精密程度的要求的越来越高,加工设备的机械加工设备的加工精密程度也要求越来越高。而在中国的机械加工设备的车床中的普通车床占了很大比例。这已经越来越制约着当今工业的发展。而数控机床由于价格昂贵,且需要较高的技术的加工工人。所以对机床进行自动化改造很是不要。在搜索、查阅研究大量有关资料的基础上,对机床自动化改造技术进行了深入的研究和分析,并描述了机床控制系统的设计。整个改造过程主要所车床纵、横向进给系统进行改造,整个控制系统以单片机位中心,通过编程对机床的驱动设备进行控制以达到所需要的加工程度。

ABSTRACT
With the development of society, technology is developing rapidly, and the numerical control technology application scope expanding increasingly, nc machine tools and systems have e modern machines manufacturing indispensable constituent part. In view of our country ownership of big, industrial production machine characteristics of small scale, outstanding task is to use less capital change rapidly machinery industry backward production face, make possible to improve automation degree, guarantee the machining quality, reduce labor intensity, and increase economic efficiency. And to achieve this task effective, basic way is to popularize and apply to the original, and the economical nc machine tools C transformation.
Nc machine tools as electromechanical integration in the typical product in machinery manufacturing, plays a huge role, solves in modern machinery plex structure, precision and small batch, changeable parts processing problem, and product processing quality can stable, and greatly improve the production efficiency. Industrial equipment for precision degree of required more and more high, processing equipment mechanical processing equipment processing precision degree also demand is higher and higher. While in China mechanical processing equipment of the ordinary lathe lathe very much a proportion. This has increasingly restricts the current industrial development. C machine because expe
