Within this research work a methodology for investigating the tribological conditions within sheet-bulk metal forming has been developed and realized. For the first time it is possible to investigate the different appearing load cases within sheet-bulk metal forming operations with the same sheet metal raw material by using the strip drawing test and the specifically adapted ring and pin extrusion test. Thus, the friction coefficient as well as the friction factor can be determined under comparable conditions, which is essential for numerical investigations. With this methodology it is possible to recommend suited tribological systems for sheet-bulk metal forming by investigating different lubricants and workpiece topographies towards their applicability. Furthermore, the studies on tailored surfaces, which are locally adapted workpiece surfaces, have shown that it is possible to influence the material flow in sheet-bulk metal forming in a directed way and thus to achieve a significant increase in mold filling.
