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

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.
