基于微纳米摩擦学的超精密加工技术研究进展

回顾了超精密加工机理研究的几种主要方法，重点介绍了结合微观摩擦磨损和分子动力学模拟的微纳米加工材料去除机理的研究现状。在此基础上，简单讨论了微摩擦磨损与微纳米切削加工的关系，试图说明当切削深度小到接近于刀具的刃口半径时，微纳米切削加工中刀具与工件的作用过程近似于滑动摩擦作用过程，基于微摩擦学的微纳米加工机理的研究是合适的、有意义的。

Development of ultraprecision machining based on micro/nano-tribology

Several main methods on the study of ultra-precision machining mechanism are briefly reviewed. The current status of the re- search on mechanisms of materials removal in micro/nano-cutting in combination with micro/nano-tribology and molecular dynamics simulation is introduced in detail. On the basis of the discussion about the relationship between micro/nano-tribology and nano-cutting, an attempt was made to explain that when cutting depth is reduced to the size of the edge radius of the cutting tool, the acting process between the cutting toolandthe workpieceisapproximately sliding friction cutting. The study of micro/nano-machining mechanism based on micro/nano-tribology is appropriate and valuable.
