Roughness Texturing and its Influences on the Tribological Behaviour in Forming Processes

Sheet metal forming processes are increasingly focused on tribological parameters, and the sheet metal surface topography is nowadays a characteristic that show great potential for the process optimisation. In this paper, three different surface textures of an aluminium alloy AA 6016-T4 are characterised by 2D and 3D surface analysis methods. The effects of the surface topography on the friction behaviour and the formability were investigated by means a twist-compression test and a deep-drawing test, respectively.
