Kurzbeschreibung (Abstract)

Dynamic processes like machine hammer peening generate a smoothing of tool surfaces, an increase in hardness and residual compressive stresses in the surface layer. So far, it is not possible to determine the energy threshold needed to smooth a rough surface based on tool parameters and workpiece characteristics. Thus, this paper focuses on the definition of an energy threshold as well as the derivation of an analytical equation to calculate the energy demand for plastic deformation. The method is validated by experimental investigations. It is shown that the defined energy threshold for mechanical surface smoothing corresponds with the experimental data.
