立式数控铣床工作台(X轴)进给传动系统的设计

设计题目：立式数控铣床工作台（X轴）进给传动系统的设计

摘要

制造业是国民经济和国防建设的基础性产业，先进制造技术是振兴传统技术是振兴制造业的技术支撑和发展趋势，是直接创造社会财富的主要手段，谁掌握先进制造技术，谁就能够占领市场。而数控技术是先进制造技术的基础技术和共性技术，已成为衡量一个国家制造业水平的重要标志之一。

我国数控技术及产业尽管在改革开放后取得了显著的成就，开发出了具有自主知识产权的数控平台，即以PC为基础的总线式、模块化、开放型的单处理器平台，开发出了具有自主知识产权的基本系统，也研制成功了并联运动机床，但是我过的数控技术及产业与发达国家相比仍然有比较大的差距，其原因是多方面的，但是最重要的是数控人才匮乏。

Abstract

Manufacturing industry is the foundation of the national economy and national defense industry, advanced manufacturing technology is the revitalization of traditional technology is the revitalization of technical support and development trend of the manufacturing industry, is the main means to create social wealth, who master the advanced manufacturing technology, who will be able to occupy the market. Numerical control technology is the basic technology and common technology of advanced manufacturing technology, which has become one of the important signs to measure the level of a country's manufacturing industry.

China's CNC technology and industry even after the reform and opening up has made remarkable achievements, the development of the NC platform with independent intellectual property rights, which is based on PC bus modular open type single processor platform, developed the basic system with independent intellectual property rights, also developed a parallel motion but I have the machine tool, numerical control technology and industry compared with the developed countries is still a relatively large gap, its reason is i

Key words: numerical control technology
