The part life span significantly depends on microstructure and the residual stress state. The current state of research shows that the mechanical surface strengthening process deep-rolling is a suitable method for alteration of surface and subsurface properties to increase strength and life span of highly stressed components. A further increase in the life span can be reached by using the process temperature of the turning process to enhance the influences of deep rolling. For this purpose, a turn-rolling tool was developed. Especially concerning soft machining operations, the induced process temperatures can lead to higher compressive residual stresses, and finally, to higher part life spans. For this, it is necessary to consider the influence of heat on the component caused by the turning process. Therefore, a novel approach to the design of process parameters and tool geometries for turn-rolling based on 3D FEM simulations was developed in this work. Based on this approach, it was shown that depending on process parameters and tool microgeometry, the component temperature can be specifically influenced near the surface.

零件的寿命很大程度上取决于显微组织和残余应力状态。目前的研究状态表明，机械表面强化工艺深轧是改变表面和亚表面性能以增加高应力部件的强度和寿命的合适方法。通过使用车削过程的过程温度来增强深轧的影响，可以进一步延长使用寿命。为此，开发了一种车削工具。特别是在软机加工方面，所引起的过程温度会导致较高的压缩残余应力，并最终导致较高的零件寿命。为此，有必要考虑由车削过程引起的热量对部件的影响。因此，在这项工作中，开发了一种新颖的方法来设计用于3D FEM模拟的车削工艺参数和刀具几何形状。基于这种方法，结果表明，取决于工艺参数和工具的微观几何形状，部件温度会受到表面附近的特定影响。
