OPTIMIZING FRICTION BETWEEN DIE AND SHEET METAL

摘要

In deep drawing and drawing of car body parts the friction conditions are of great influence on process limits, on the robustness of the production process and on the quality of the produced parts. Beside the used lubricant, the friction conditions are influenced by the topography of the sheet metal surface and by the topography of the tool surface. This paper deals with the influence of sheet metal surfaces, coatings on sheet metal surfaces, tool surfaces, coatings on tool surfaces, and with the influence of the lubrication on the frictional behavior.
