摘　　要：基于有限元分析软件Deform-3D,预测了大刃倾角切削金属纤维时的流屑角。获得了在不同刃倾角、法向前角、切削厚度下的流屑角的变化曲线,并将模拟计算的结果与试验结果作对比,具有较好的一致性。Based on the finite element analysis software Deform-3D, the angle chip flow angle was predicted in the process of cutting metal fiber. The variety curves of angle chip flow angle were obtained for a range of cutting edge inclination angles, tool normal rakes and cutting deeps. The calculated predictions of angle chip flow angle are well agreed with experimental data.
