摘要 随着数控技术的飞速发展,机械制造业的生产方式、产品结构、发生了深刻的变化。在我国数控机床的发展过程中,MCS-51系列单片机在数控技术领域中得到广泛应用,经济型数控系统大多采用MCS-51系列单片机。 本文在分析了数控车床的特点和实验台应该具备的功能后,确定采用基于单片机控制的系统总体结构方案。设计方案由系统硬件结构和系统软件结构两部分组成。 关键词:数字控制,单片机系统,数控车床 ABSTRACT With the development of NC, there have been many changes in mechanical industry, such as producing method and struture of product. MCS-51 single puters have been used widely in NC, especially in ecomical NC equipments in china. Based on MCS-51 single puters, the NC lathe training equipment is designed with less money for the professional NC courses. After analyzing the feature of NC lathe and defining the functions of training equipment, a system general scheme is assumed by hardware architecture and software architecture, which uses MCS-51 single puter.
