在铜的正交切削中，施加在切屑上的张力带来以下结果：（1）切屑厚度和刀具力从1/2减小到1/3。(2)包括芯片提拉功率在内的总功耗也降低到1/2左右。拉力的这些显著效果主要是由于拉力和拉力引起的弯矩减小了刀-屑接触面积和刀-屑摩擦力，增大了剪切角。弯矩使切屑根部产生塑性弯曲。因此，切屑形成的机制似乎非常复杂。
In the orthogonal cutting of copper, the tension applied to the chip brings the following results : (1) Chip thickness and tool force are decreased to from 1/2 to 1/3.(2) The total power consumption including the power for the pull of chip is also decreased to about 1/2. The decrease in the power consumption is as large as from 6 to 40 times, the power consumed by the pull.These remarkable effects of the tension are mainly attributed to the fact that the tension and the bending moment induced by the tension decrease the tool-chip contact area and the tool-chip friction, and increase the shear angle. The bending moment produces the plastic bending at the root of chip. The mechanics of chip formation, therefore, seems very intricated.
