数控专业毕业论文

第一篇：数控专业毕业论文河南农业大学2010届毕业论文摘要世界制造业转移，中国正在逐步成为世界加工厂。美国、德国、韩国等国家已经进入工业化发展的高技术密集时代与微电子时代，钢铁、机械、化工等重工业正逐渐向发展中国家转移。我国目前经济发展已经过了发展初期，正处于重化工业发展中期。未来10年将是中国机械行业发展最佳时期。美国、德国的重化工业发展期延续了18年以上，美国、德国、韩国四国重化工业发展期平均延续了12年，我们估计中国的重化工业发展期将至少延续10年，直到2015年。因此，在未来10年中，随着中国重化工业进程的推进，中国企业规模、产品技术、质量等都将得到大幅提升，国产机械产品国际竞争力增强，逐步替代进口，并加速出口。目前，机械行业中部分子行业如船舶、铁路、集装箱及集装箱起重机制造等已经受益于国际间的产业转移，并将持续受益；电站设备、工程机械、床等将受益于产业转移，加快出口进程关键词:数控工业化发展刀具机床/27河南农业大学2010届毕业论文目录第一章数控机床的产生第二章数控机床的发展2.1数控系统的发展···············································································12.2机床的发展趋势···············································································2第三章数控机床的分类3.1按加工工艺方法分类·······································································43.1.1金属切削类数控机床························································································43.1.2特种加工类数控机床························································································43.1.3板材加工类数控机床························································································43.2按控制运动轨迹分类·······································································53.1.2点位控制数控机床·····························································································53.2.2直线控制数控机床·····························································································53.2.3轮廓控制数控机床·····························································································53.3按驱动装置的特点分类···································································63.3.1开环控制数控机床·····························································································63.3.2闭环控制数控机床·····························································································73.3.3半闭环控制数控机床························································································73.3.4混合控制数控机床·····························································································7/27河南农业大学2010届毕业论文第四章数控车的工艺与工装削4.1合理选择切削用量·····
