“…by the surface texturing of dies) has been experimentally investigated by several researchers (Azushima and Kudo, 1995;Bech et al, 1998;Ike, 1996;Sheu and Hector, 1999;Sheu et al, 1998;Sorensen et al, 1999;Steinhoff et al, 1996;Wihlborg, 2000) whose work has been mostly related to tests involving severe plastic deformation. In the present work, strip drawing was used as a model experiment to investigate the effects of controlled surface patterning on friction and lubrication in tribological situations which involve small extents of plastic deformation of the workpiece.…”

“…Tactile friction requires an in-depth understanding of the contact mechanics and the behavior of human skin. Surface textures can be categorized as deterministic nature or as stochastic nature (Steinhoff et al, 1996). Deterministic textures have a repetition of fixed geometric structure, and stochastic textures are non-deterministic with random surface pattern.…”

a b s t r a c tTo control tactile friction, that is the friction between fingertip and counter-body, the role of surface texture is required to be unveiled and defined. In this research, an experimental approach is used based on measuring tactile friction for directional texture (grooved channel) with varying depths. For a reference surface, in this current case a polished surface from the same tool steel is compared. The experimental results are analyzed to explain the observed skin friction behavior as a function of surface texture parameters, sliding direction and applied normal load. Sliding parallel to the groove length shows greater values in COF than sliding perpendicular to the groove direction. Furthermore, parallel sliding reveals a higher dependency of COF on the depth of the grooved channel texture than perpendicular sliding. Application of the two term friction model suggests that the adhesion component of friction has greater impact on parallel than perpendicular sliding direction. According to the observations, grooved channels are well suited to control skin friction in direction dependent sliding, for moderately loaded contact situations. This experimental research contributes to the haptic perception related research, and to the development of other direction-dependent surface structures for touch.

“…In sheet metal forming, this is realized by thermal hardening and surface coatings on the tools [20] or a surface texturing (structuring) of the workpieces [21]. Steinhoff [22] describes the tasks of surface textures with the transport and distribution of lubricant into the deformation zone and the absorption and transport of abrasive particles out of the contact zone. Since these tasks cannot be fulfilled by smooth surfaces, the texturing of sheet metal is state of the art.…”

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.
