Abstract
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.
