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

可靠的知识的负载轮廓的切削刃是必不可少的有效的切削刀具的发展。因此，不同切割操作和材料的过程力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在切割过程中的过程力，需要一个广义的结构是一个中心要求。在本研究工作中，将建立车削操作的广义力模型。这是基于两种新的力建模方法关于未变形的切屑的横截面以及在切削边缘的微观几何。该模型将通过包括切割条件的已知影响而一般化。相关材料特性的进一步未知影响将被系统地研究。这项工作的结果将是基于相关材料特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.
