摘　　要：通过分析切削过程中切屑与刀具前刀面之间的摩擦情况,提出减少切屑与刀具前刀面的接触面积能降低切屑与刀具之间的摩擦,从而减小主切削力。据此设计了一种带减摩槽的三维槽型刀片,并通过切削试验证明了减摩槽能有效减小主切削力并改善刀片断屑性能。The friction between the chip and tool rake face in cutting process is analyzed, and it is concludes that reducing the contact area between the chip and tool rake face can reduce the friction between them, so the main cutting force can decrease too. Based on it, a new type of three-dimensional chip-breaking grooves with friction-reducing grooves is designed, and the conclusion that the friction-reducing grooves can reduce the main cutting force and improve the chip-breaking performance of the cutter is confirmed by cutting test.
