摘要
在脆性材料的超精加工中,一个十分重要的现象是材料由脆性状态向可延展性状态的转变.为了成功地对脆性材料进行钻石切削加工以获得镜面表面,两种状态转变点的确定十分关键.本文阐述研究这一转变的实验技术,并讨论表面生成的机理.发现在脆性材料的钻石切削中,刀具磨损是一个严重后果.建议今后的研究应集中在这一领域.
In ultra-precision machining of brittle materials, a very important phenomenon is the material transition from brittle to ductile mode. To successfully diamond-turn brittle materials to a mirror surface finish, it is critical to determine the transition point from between the two modes. This paper presents the experimental techniques to study this transition and discusses the mechanism of the surface generation. It has been recognized that the tool wear is a serious issue in diamond turning of brittle materials. Thus, it is suggested that the research in future should be concentrated on this field to enable the technology to be applied practically in production.
