摘要
机械制造业是国民经济的支柱产业,可以说,没有发达的机械制造业,就不可能有国家的真正繁荣的富强。而机械制造业的发展规模和水平,则是反应的重要标志之一。提高加工效率,降低生产成本,提高加工质量,快速更新产品,是机械制造业竞争和发展的基础,也是机械制造业技术水平的标志。
20世纪50年代初第一台数控机床出现了,数控机床是典型的机电一体化产品,综合了精密机械、电子、电力拖动、自动控制、自动检测、故障诊断和计算机等方面的技术。数控机床的高精度、高效率及高柔性决定了大力推广使用数控机床是我,提高市场适应能力和竞争能力的必由之路。
数控铣削加工是机械加工中最常用和最主要的数控加工方法之一,加入WTO以来,我国汽车工业、航空航天工业得到了快速发展,大量具有复杂曲面的零件如模具、叶片和螺旋浆等,都需要用数控铣床进行加工。
本设计以数控铣床加工工艺、编程与操作为核心内容,重点介绍了数控铣床加工工艺,数控铣床的编程方法,数控铣床的操作方法,典型零件数控铣床加工综合实训等方面的知识及应用实践技能。

Abstract:
Machinery manufacturing industry is a pillar industry in the national economy, it can be said that without a developed machinery manufacturing, it is impossible to state the true prosperity of the prosperity. And machinery manufacturing scale and level of development, economic strength and scientific and echnological level of response is one of the important signs. Improve processing efficiency, reduce production costs, improve processing quality and rapid updating products, machinery manufacturing and development on the basis petition, machinery manufacturing technology is a symbol.
First in the early 1950s, the 20th century C machine tool, mechanical and electrical integration is a C machine tool products, integrated precision machinery, electronics, electric traction, automatic control, automatic detection, fault diagnosis, puter technology in such areas. High-C machine tool. high efficiency and high flexible decision is vigorously promoting the use C machine tool manufacturers to increase manufacturing capacity, improve their ability to adapt petitive ability.
CNC milling machining is the monly used method of NC and the main one, since the accession to the WTO. China's automobile industry, the aerospace industry has been developing ra
