摘要
随着科学技术和社会的不断发展,社会对产品多样化的要求日益提高,产品更新换代越来越快,多品种小批量生产比重加大,零件形状越来越复杂,精度越来越高,此外,激烈的市场竞争要求产品研制周期越来越短,传统的加工设备和制造手段已经难于满足这种变化,为了解决这些问题,数控机床就这样应运而生。
数控技术是集,机,电,液及计算机等各项技术为一体的综合技术,数控机床以其精度高,效率高,能适应小批量多种复杂零件加工的特点,在机械加工中得到日益广泛的应用,
在本次设计中,就包括了关于数控技术的基本知识,并且针对本次设计的课题,拟定了一系列的方案,进给系统的总体方案,数控车床进给传动系统的机械部分,以及数控系统的硬件分析和设计。

Abstract
Along with science and technology and the development of society, the society for increasing product diversification requirements, product update more and more quick, many varieties small batch production increased, parts shape proportion of more and plicated, the accuracy is higher and higher, in addition, the fierce petition requires shorter product development cycles, the traditional processing equipment and manufacturing technique has been difficult to meet this change, in order to solve these problems, nc machine tools so arises at the historic moment.
Numerical control technology is the collection, machine, electricity, liquid puter etc various technique is a prehensive technology, nc machine tools to its high accuracy, high efficiency and can adapt small batch plex parts processing the features in machining the get increasingly widely
In this design, including about the basic knowledge of numerical control technology in the design, and the topic, drew up a series of solutions, feeding system, overall scheme of C lathe into give transmission system, and the mechanical parts of C system hardware analysis and design.
