Abstract

Wear in sheet metal forming processes is influenced by numerous variables. Their impact has so far been investigated in model tests neglecting forming-specific tribological boundary conditions such as continuous infeed of new sheet metal material and lubricant as well as high local contact stresses. This paper proposes a new testing method which overcomes these deficits and allows for a high resolution of wear formation in time. Thus, the wear behavior of different tribological systems under different load conditions is compared. Both the reproducibility and transferability of the results are discussed. Furthermore, a new characteristic value is derived in order to characterize the tribological load of different tribological systems so as to provide the possibility of wear prediction.
