摘　　要：使用经刃口钝化后的刀具进行切削加工是提高刀具切削稳定性、降低刀具磨损、节省加工成本及提升产品表面质量的重要措施。本文回顾了刀具切削刃刃口研究领域的发展历程,并对最新研究成果进行了总结归纳,介绍了刀具刃口几何形状的描述方法,阐述了在切削过程中刀具刃口几何形状对切屑成形及流动、切削力、切削温度、残余应力、刀具寿命和加工表面质量的影响规律。最后,对刀具刃口未来的研究方向提出了展望,针对不同加工材料及加工参数下最佳刃口的选取、针对不同刃口形状上的涂层与基体材料之间的相互作用以及在微纳制造中近原子及原子尺度下刀具刃口半径对材料去除机理的影响还需要进一步系统论证。It is an important measure to improve cutting stability,reduce tool wear,save machining cost and improve product surface quality by using the tool after being passivated by cutting edge.In this paper,the development of the research field of tool edge was reviewed and the latest research results were summarized.The description methods of tool edge geometry were introduced.And the influence of tool edge geometry on chip formation,cutting force,cutting temperature,residual stress,tool life,and surface quality during cutting progress was illustrated.Finally,the future direction of tool edge was proposed.The selection of the best cutting edge under different processing materials and processing parameters,the interaction between coating and matrix on different cutting edges type,and the influence of the cutting edge radius on the material removal mechanism at the atomic scale and near atomic scale in micro-nano manufacturing need to be further demonstrated systematically.
