The influence of tool roughness on roughness transfer in skin-pass or temper rolling of steel strip is investigated, focusing on loading under combined normal and tangential displacement of tool relative to the workpiece. The calculated roughness transfer by an elasto-plastic finite element (FE) simulation of plane strain indentation in authors' previous paper [H. Kijima. N. Bay, Skin-pass rolling I-studies on roughness transfer and elongation under pure normal loading, International journal of Machine Tools and Manufacture, May 2008, accepted for publication] is verified by experimental measurements in this paper. The experiment shows a significant influence on roughness transfer of tangential displacement of workpiece in the sticking and the sliding region. The FE calculations modelling the sticking and sliding region reveal the mechanisms of plastic deformation and roughness transfer. (C) 2008 Elsevier Ltd. All rights reserved.
