摘　　要：通过试验,找出了切削深度、切削速度、每齿进给量等切削用量及切出角影响面铣刀寿命的规律。分析了切削过程中切削力的变化情况,并指出负剪切现象对刀具破损的影响。在应用弹性理论对刀具破损进行应力分析的基础上,指出提高刀具寿命的措施。Tests are conducted to find the rules how such cutting parameters as cutting depth, cutting speed and feedrate per blade as well as the cutting angle affect on the life of face mill. Analysis is conducted for the variation of cutting force during the cutting process and the effect of negative shearing on the cutter damage is pointed out. Based on the stress analysis for cutter damage with elasto - mechanics theory, measures for improving cutter life are proposed.
