Abstract
The process deep drawing is influenced by several parameters: one of the most important is the friction at the flange as well as the radius of the die. This friction is also effected by the sizeeffects. This paper describes a new friction test method for deep drawing applications, which is suited for investigations in different dimensions. Thus this method can be used to study the sizeeffects. The FC function (friction coefficients function) was derived from the results of strip drawing investigations to describe the friction behaviour in the whole deep drawing process.
