Liquid lubricants are generally used in metal forming processes to decrease friction between tool / workpiece interface. In recent studies it is indicated that the undulation on workpiece surface induces the micro hydrostatic and hydrodynamic lubrication mechanisms thus enhances the decreasing friction. However, the influence of surface topography on the local lubrication phenomena has not been fully clarified. In the present study, the rigid-plastic finite element analysis of strip drawing process was performed with the workpiece that has lubricant pockets on surface. The influences of the pocket shape as well as the working conditions on the stress distribution and the lubricant behavior were discussed with respect to the micro lubrication mechanisms.
