关于金属切削过程中刃区物的受力分析

The Stress Analysis of the Material on the Edge Section in the process of Metal Cutting

摘要: 本文第一次提出了刃区物(Material on the edge section)的概念。认为,前刀面流变层及积屑层、后刀面流变层及积屑层、副屑,积屑瘤,鳞刺等均是刃区物的衍生物。文中对刃区物的受力状态进行了分析,提出了刃区物受力状态模型,并对各种衍生物的产生条件进行了分析。

Abstract: In this paper, the concept of material on the edge section is put forward for the first time. It is believed that the flow layer and built-up layer on the face and flank, the additional chip, the built-up edge and the scale are all derivatives from the material on the edge section. Stress state of the material on the edge section is analysed and a stress model is given. The conditions which the various derivatives result from are also studied in this paper.
