摘　　要：运用分子动力学模拟技术建立单晶铝纳米切削模型 ,对纳米切削过程进行模拟 ,从分子间作用力和位错的角度对切屑形成过程和纳米加工表面的形成机理进行分析 ,并对切削刃刃口半径的大小和刀具磨损对已加工表面质量的影响进行研究。In this paper, a nanometric cutting model of single crystal Al was built by molecular dynamics simulation technique, and the nanometric cutting process was simulated. From the interaction points of view between workpiece atoms and tool atoms and dislocation, the chip formation and the surface generation mechanism were analyzed, and the effects of cutting edge radius and tool wear on the machined surface were studied,too.
