Summary:Avoiding lubricants in forming processes like the deep drawing process is an important way to save resources in today's industry. In this paper, a method will be presented for the elimination of lubrication in the deep drawing process by means of a new macro structured tool design. This structuring enables the control of friction forces as well as the material flow. The paper will present the basic process principle, an analytical model for the process design and experimental results. Starting with symmetrical geometries, the outlook will be given for three-dimensional, complex parts.
