| 摘 要： | 采用四种硬质合金涂层刀片对45和T10A淬硬钢两种材料进行了正交切削试验,通过所测得的三向切削力计算了前刀面平均摩擦系数,详细分析了前刀面摩擦系数随切削过程的变化情况,以及切削参数对摩擦系数的影响。结果表明前刀面摩擦系数随切削过程的进行迅速减小并趋于稳定,表征了涂层刀具切削淬硬钢时的自组织现象。

| Abstract: | Cutting experiments were performed for turning two kinds of hardened steel with four types of coating tools by orthogonal experimental method.The friction coefficient on rake face was calculated through the tested cutting forces.The curves of the friction coefficient changing with the cutting process and its dependence on the cutting parameters were analyzed in detail.The results show that the friction coefficient on rake face decreases rapidly during the cutting progress and comes to a steady value,which could be an indication of the self-organization when turning hardened steel with coating tool. |
