    摘要:

    对PCD刀具微细切削加工刃下区的弹性应力、弹性位移和弹塑性分界线方程进行了推导,利用PCD刀具进行微细切削无氧铜和硬铝的实验,并对工件表面进行了SEM分析,指出侧向塑流和纵向塑流是影响工件表面粗糙度的主要因素,通过对后刀面熨压作用的分析,提出了PCD刀具后刀面刃磨方向应平行于刀具刃口的建议。

    Abstract:

    The elastic stress and displacement of the machining area under PCD cutting edge during the superfine cutting was studied theoretically, and the boundary equation between the elastic and plastic area developed. Experiments using PCD cutting tool to cut hard AL and Cu were conducted. The surface of the workpiece obtained was analyzed with SEM method. It was demonstrated that sideways and lengthways plastic transformation were the main factors affecting the roughness of the workpiece surface. the authors suggested that the grinding trace on the rear surface of the tool should parallel the edge.
