Effect of surface texture on deformation behavior of asperity in cold metal forming

Conference Paper


Abstract


  • It was impossible to obtain the transverse friction along the strip width in most previous studies of cold strip rolling because the surface roughness lays were assumed to be vertical to the rolling direction. In this study, several types of oblique roughness textures were manufactured on aluminum samples and compression tests were carried out to obtain the effect of different textures on the deformation behavior of surface asperity. Different surface textures resulted in very different peak value of stress. It was found that stress was high and changed dramatically at the initial compression stage but tended to be stable when the total reduction increased. The asperity of which the top angle is 160° showed relatively high resistance to deformation.
