摘　　要：金属切削加工在机械制造业中占有重要的地位。切削工艺包括有车、刨、钻、铣等不同的类型,利用切削刀具从毛坯上切除多余的金属,以获得要求的形状、尺寸和表面精度零件的加工方法。金属工件的切削加工过程中,在已加工工件表面形成的鳞刺会严重影响工件表面质量。本文通过对鳞刺的产生原因和形成机理进行深入的探讨,并从中分析出抑制或减少鳞刺产生的具体方法,减小已加工表面粗糙度,从而达到改善金属切削加工工件表面质量的目的。Metal cutting plays an important role in machinery manufacturing.Cutting technology includes turning,planing,drilling,milling and other different types.Using cutting tools to remove excess metal from blanks to obtain parts with the required shape,size and surface accuracy.During the cutting process of metal workpieces,the burr formed on the surface of the machined workpiece will seriously affect the surface quality of the workpiece.This paper makes an in-depth discussion on the causes and formation mechanism of burrs,and analyze the specific methods to inhibit or reduce the generation of burrs,reduce the roughness of the machined surface,so as to achieve the purpose of improving the surface quality of metal cutting workpieces.
