1、- I - 摘要 现代数控机床是未来工厂自动化的基础。旧机床数控化改造范围大、 潜力大、投资少、 见效快，已经成为适合我国国情，促进制造业技术进步的重要手段。因此，数控系统改造 车床的研究具有重要意义。 本文在叙述了数控技术的历史、现状和发展的基础上，通过对旧机床的分析，结合机 床改造的总体思想，提出了数控化改造的技术方案和新数控系统的选型配置方案;针对旧 机床的要求，进行了传动系统的重新设计，提高了传动的精度，重新设计机床的控制逻辑， 通过对伺服系统的分析，完成了机床各主要参数的优化和匹配。 本机床改造后将会展示出强大的功能、稳定的性能，将完全符合机床的技术规格和精 度标准，加工出合格的零件
2、，大大提高了车床的性能，是一次有益的尝试。 关键词：CA6163;机床;改造;数控系统。 - II - Abstract The modern Computer Numerical Control （CNC） machine is the foundation of the modern manufactory. The remaking of old machine for CNC is an efficient means to promote the progress of the manufactory, which is adapted to the circumstance for
3、 our country. Its range is wide, its cost is low and its period is short. Therefore, it is very important to study a remarking the lathe machine by using CNC system. This paper introduces the history and the development of CNC system. Based on its theory, through the analysis about the components of
4、 the old machine, presents the remaking transmission system to raise the precision of the lathe。Presents the remaking schemes of the CNC system. According to the old machine, the detail design and adjustment of the electric system have been completed, including the design of hardware and control software：Have introduced the one-chip computer system briefly, and has designed the electric control circuit of the numerical control lathe with the one-chip computer；And also redesign the control logic
