In Sheet Metal Forming (SMF) processes, such as deep drawing, friction plays an important role. Together with the deformation of the sheet, the friction determines the required punch force and the blankholder force. Consequently, the friction in uences the energy which is needed to deform a sheet material. Friction also in uences the stresses and strains in the workpiece material and, hence, the quality of the product. Therefore, it is important to control the friction between the tools and the workpiece.
