It is one of the most widely used methods to groove and disconnect the workpiece with the cutter,but in the process of cutting the movement of the cross-feed can reduce the working orthogonal clearance,which increases the friction between the tool flank of the cutting tool and the machined surface,and hence results in the break of the workpiece and the working tool.

用切断刀对被加工工件切断或切槽是生产中应用最广泛的加工方法之一，但在切削过程中横向进给运动的影响使刀具工作后角减小，加剧了刀具后刀面与加工表面之间的摩擦，从而会导致工件被挤断，刀具易折断。
