| 摘 要： | 在涂层前,对基体做梯度处理,可以阻止热应力引起的裂纹的扩展,提高刀具的强度,韧性和切削性能,本文建立了具有富钴梯度结构的涂层硬质合金刀片的数值模型,利用Deform 3D软件对有无梯度富钴层的两种刀片的切削过程进行了计算机仿真。增加富钴梯度结构后,切削力减小,刀片表面温度升高、但基体温度梯度更加收敛,刀具塑性变形减小同时切屑的有效应力、应变增大。仿真结果对刀具梯度结构的选择及设计具有参考价值。

| Abstract: | Before coating,gradient treatment on the substrate can prevent the crack propagation produced by thermal stresses and improve the strength,toughness and cutting performance of the insert.The numerical model of coated carbide inserts with cobalt-rich gradient structure was created,and the simulation model of cutting process of two inserts with and without a gradient of cobalt-rich layer was established based on Deform 3D software in this article.After adopting the cobalt-rich gradient structure,the cutting f... |
