为了确定刀具切削刃几何形状对AISI 52100全硬化钢精硬车削工件亚表面变形和全厚度残余应力的影响，进行了一项实验研究。本研究使用具有上锐边、磨边和倒角的多晶立方氮化硼（PCBN）刀片作为切削工具。对工件微观结构的检查表明，大型刃磨刀具会产生大量次表面塑性流动。对全厚度残余应力的检查表明，大型刃磨工具比小型刃磨工具或倒角工具产生更深、更多的压缩残余应力。 基于刀具和工件之间假设的接触条件，对这些影响进行了解释。

An experimental investigation was conducted to determine the effect of tool cutting edge geometry on workpiece subsurface deformation and through-thickness residual stresses for finish hard turning of through-hardened AISI 52100 steel. Polycrystalline cubic boron nitride (PCBN) inserts with up-sharp edges, edge hones, and chamfers, were used as the cutting tools in this study. Examination of the workpiece microstructure reveals that large edge hone tools produce substantial sub-surface plastic flow. Examination of through-thickness residual stresses shows that large edge hone tools produce deeper, more compressive residual stresses than small edge hone tools or chamfered tools. Explanations for these effects are offered based on assumed contact conditions between the tool and workpiece.
