Kurzbeschreibung (Abstract)

Cold forging is an established manufacturing process challenged by increasing requirements regarding precision, robustness and productivity. The economic efficiency of cold forging depends on the tribological system. Tribological conditions in cold forging are extremely severe and of high complexity. To satisfy the increasing demands, an optimized design of the process and continuous development of tribological relevant components is necessary. This paper presents a method to analyze the complex tribological processes of cold forging using a laboratory test method and numerical simulation. The method provides a deeper insight to the characteristic of friction and wear properties of tribological systems. It is characterized by a specific consideration of the influence of individual variables such as exposure to thermal load by heated tools, distribution of surface expansion, contact normal pressure, sliding velocity and sliding distance. The specific behaviour of lubricants in interaction with tool surfaces and working materials could be characterized by the variation of load parameters. The gained knowledge may contribute substantially to the design of industrial processes and to the assessment of newly developed lubricants and coatings
