数控铣床进给传动设计_毕业论文.doc

摘要 机械制造业是我国经济的支柱之一，一个国家如果没有发达的机械制造业，就不会有国民经济的发展。而机械制造业的发展水平反映了国民经济的繁荣。数控机床技术在当今世界具有更重要的经济地位和战略地位，目前工业发展趋势在世界经济和数控机床技术的体现，现在的核心产业和现代技术都是建立在数控机床技术的，因此，数控机床技术是反映一个国家的工业水平和现代技术水平的成熟程度。而数控机床技术水平的高低，体现了国民经济的实力。目前，它是整个国家乃至全世界第一个实现机床加工和数控技术的目标。 数控技术与数控机床在当今机械制造业中的重要地位和巨大效益，显示了其在国家现代化建设中的战略地位。数控技术是制造业实现自动化、柔性化、集成化生产的基础，是现代计算机辅助设计、计算机辅助设计等在数控技术中的应用。数控技术是一个国家战略地位，反映了国家综合国力水平的重要基础产业，是衡量一个国家制造业现代化程度的核心标志，实现加工机与数控加工的生产过程，是当今制造业发展的方向。 这项任务使我们能够更熟练地运用专业知识，并使我们的专业知识更实用。 关键词：数控机床、切削功率、滚珠丝杠副。 Abstract Machinery manufacturing industry is one of the pillars of Chinas economy, A country if there is no developed machinery manufacturing industry, Will not have the development of the national economy. And the level of the development of machinery manufacturing industry, Reflecting the prosperity of the countrys economy. CNC machine tools in todays world has a more important economic status and strategic position, The industrial development trend and the trend of economic development in the world, The technology of the numerical control machine tool reflects the core objective of the industrial industry, Some of the modern technology is based on the technology of CNC machine tools, So, the technology of the numerical control machine tool is a reflection of the level of a countrys industry and the maturity of the modern technology. And the level of the technical level of the numerical control machine tool reflects the strength of the national economy. At present, it is the first goal of the whole country and even the world to realize the machining of the machine tools and to make the numerical control technology. CNC technology and CNC machine tools in todays machinery manufacturing industry in an important position and great benefits, showing its strategic role in the modernization of the countrys basic industries. CNC technology is the manufacturing industry to achieve automation, flexible, integrated production base, modern CAD / CAM and so on are established in the numerical control tech
