Functional Surface Characterization in Sheet Metal Forming



Project Status: finished

Members


The interaction of the surface properties between tool and workpiece has an important influence on the quality of the forming process. For the characterization of the tribological behaviour of sheet metal surfaces during the forming process by functional parameters, it is essential to gain detailed knowledge about the tribological mechanisms in the workpiece-tool interface. The specification of the tribological behavior is done by strip drawing test, to determine the flattening behaviour of sheet metal surfaces under normal load and relative movement. For the detailed description of the tribological mechanisms in the workpiece-tool interface, an upper punch device with a transparent tool is used, thus enabling the in-situ investigation of the flattening behaviour in the workpiece-tool interface. The goal of the project is to establish fundamental knowledge about the tribological mechanism at the workpiece-tool interface and therewith to advance the development of functional surface parameters, which allow to predict the tribological behaviour.
