Influence of the honed cutting edge on process forces in relation to the variable cross-section of undeformed chip

可靠的刀具刃口载荷分布知识对于高效的刀具开发是至关重要的。因此，针对不同的切割操作和材料的过程力的建模是许多研究工作的主要焦点。由于有不同的方法来描述切割过程中的过程力，因此需要一个通用的宪法是一个中心要求。在这项研究工作中，将为车削操作建立一个广义力模型。这是基于两种新的关于未变形切屑横截面的力建模方法以及基于刃口微观几何的力建模。该模型将通过包括已知的切割条件的影响来推广。此外，还将系统地研究相关材料特性的未知影响。这项工作的结果将是一个基于相关材料属性以及刀具宏观和微观几何形状的广义力模型。

Reliable knowledge on the load profile of the cutting edge is essential for an efficient cutting tool development. The modeling of process forces for different cutting operations and materials is therefore in the main focus of many research works. Since there are different approaches to describe the process forces during cutting, the need of a generalized constitution is a central requirement. In this research work a generalized force model will be developed for turning operations. This is based on two new approaches for force modeling regarding the cross-section of undeformed chip as well as on the cutting edge microgeometry. This model will be generalized by including known effects of cutting conditions. Further unknown effects of relevant material properties will be examined systematically. The result of this work will be a generalized force model based on relevant material properties as well as on the cutting tool macro- and microgeometry.
