制造业是国民经济的支柱产业,是社会物质财富的源泉,对人类的生产生活和物质文明建设起着极大的推动作用。近年来,随着高新技术的发展,特别是为了发展尖端国防技术及科学研究的需要。各种新材料、新工艺、结构形状复杂的精密机械零件不断涌现,这样就对传统的机械制业提出了一系列迫切需要解决的问题。例如难切削材料的加工、薄壁特殊材料的加工等等,用传统的加工方法加工十分困难,甚至根本无法加工。这样人们就打破传统加工方法的束缚,不断地探索新的加工方法,于是,一种本质上区别于传统加工的特
Manufacturing industry is the pillar industry of the national economy and the source of material wealth of society. It plays a great role in promoting the production and material development of mankind. In recent years, with the development of new and high technology, especially in order to develop the needs of cutting-edge defense technology and scientific research. A variety of new materials, new processes, the complexity of the structure of complex mechanical parts continue to emerge, so the traditional machinery industry put forward a series of urgent problems to be solved. For example, difficult to cut material processing, thin-walled special materials processing, etc., with the traditional processing methods of processing is very difficult, or simply can not be processed. So that people break the shackles of the traditional processing methods, continue to explore new processing methods, so that is essentially different from the traditional processing of special
