Abstract
In the process combination of Hammering Turning, the workpiece surface is microtextured during machining by means of a multi-axis superimposed oscillation of the cutting tool. These microtextures are formed by plastic deformation of the surface layer in a process phase without material removal. In this paper, the formation of the microtexture in the originally three-dimensional process is investigated in simplified analogue 2D FEM simulations. This therefore only represents the processes and mechanisms directly below the cutting edge. The influence of the tool orientation on the plastic material flow and the formation of the microtexture as well as the residual stresses in the surface layer is investigated.
