Influence of Hammer-Peened Surface Textures on Friction Behavior.

Kurzbeschreibung (Abstract)

Although the tribological advantages of textured surfaces in sheet metal forming are well known, the texturing of drawing tools is not yet established due to the intensive processing efforts. With the surface treatment technology of machine hammer peening (MHP), deterministic macro- and micro-textures can be machined on free-form surfaces, while simultaneously the time need for tool production is reduced significantly compared to the conventional process chain. Therefore, this paper investigates the influence of hammerpeened surface textures on the friction behavior. First, the general texturing process is optimized and suitable process parameters are identified. Using a strip drawing test, the friction behavior of different geometrical textures, varying ratio of surface textures (area) to the total surface and different lubrication systems are determined. It is shown that MHP with surface textures can reduce friction in sheet metal forming compared to conventionally polished tools.
