数控切削技术综述

数控切削技术综述(中文4600字,英文3000字)
   数控高速切削技术(High Speed Machining,HSM,或High Speed Cutting,HSC),是提高加工效率和加工质量的先进制造技术之一,相关技术的研究已成为国内外先进制造技术领域重要的研究方向。我国是制造大国,在世界产业转移中要尽量接受前端而不是后端的转移,即要掌握先进制造核心技术,否则在新一轮国际产业结构调整中,我国制造业将进一步落后。研究先进技术的理论和应用迫在眉睫。
   1、数控高速切削加工的含义
   高速切削理论由德国物理学家Carl.J.Salomon在上世纪三十年代初提出的。他通过大量的实验研究得出结论:在正常的切削速度范围内,切削速度如果提高,会导致切削温度上升,从而加剧了切削刀具的磨损;然而,当切削速度提高到某一定值后,只要超过这个拐点,随着切削速度提高,切削温度就不会升高,反而会下降,因此只要切削速度足够高,就可以很好的解决切削温度过高而造成刀具磨损不利于切削的问题,获得良好的加工效益。

CNC Cutting Technology Review
Numerical control high speed cutting technology (High Speed Machining, HSM, or High Speed Cutting, HSC), is one of the advanced manufacturing technology to improve the machining efficiency and quality, the study of related technology has become an important research direction of advanced manufacturing technology at home and abroad. China is a big manufacturing country, in the world of industry transfer to accept the front instead of back-end of the transfer, to master the core technology of advanced manufacturing, or in a new round of international industrial structure adjustment, our country manufacturing industry will further behind. Imminent research on the theory and application of advanced technology.
