从切屑形成与折断机理出发，研究了二维刀片槽型４个几何参数对切屑上向卷曲半径及极限进给量的影响规律，推导出槽型参数影响切屑上向卷曲半径及极限进给量的理论预报关系式，为研究复杂三维刀片槽型提供依据．
Based on the mechanism of chip formation and fracture, the influences of four geometrical parameters of two-dimensional insert groove on the curl radius and the limit feed rate are studied. The influence of groove parameters on the curl radius and the limit feed rate The theoretical prediction relationship provides a basis for the study of complex three-dimensional blade groove.
