Tailored cutting edge microgeometries lead to a significant enhancement of the cutting tool performance and increase its tool life. Yet, it is so far not possible to analyze the resulting effects of the applied cutting edge microgeometry without conducting expensive experimental tool life tests.One reason for this is the incomplete understanding of the influence of the cutting edge design on the plasto-mechanical processes in the shear zones.The main objective of this research work is to achieve a fundamental understanding of the material deformation processes in the shear zones within cutting operations while adapting the cutting edge design. Furthermore, the influence of the consistency of the hone on the thermomechanical load of the wedge and the resulting wear behavior will be studied. Additionally, the influence of the workpiece material properties on the load profile on the cutting edge will be considered. Conducting specific experimental cutting operations as well as FEM-Simulations will lead to the aimed main goal of this work.

量身定做的刀具微观几何结构显著提高了刀具的性能，延长了刀具寿命。然而，到目前为止，如果不进行昂贵的试验刀具寿命测试，就不可能分析所应用的刀具微观几何的结果。原因之一是对刀具设计对剪切区塑性力学过程的影响没有完全了解。本研究工作的主要目的是在适应刀具设计的同时，从根本上了解切割操作中剪切区的材料变形过程。此外，还将研究磨头的稠度对楔形件的热机械载荷以及由此产生的磨损行为的影响。此外，还将考虑工件材料特性对切削刃上载荷分布的影响。进行具体的实验切割操作以及有限元模拟将导致本工作的主要目标。
