Abstract
During every kind of sheet metal manufacturing process, thermoelectric voltages and currents result from a temperature rise between tool and sheet metal. Their influence on the process and tool wear behavior has been investigated insufficiently so far. Therefore, Seebeck coefficients, representing thermoelectric properties, have been determined for several materials. The correlation between different Seebeck coefficients of tool, respectively, sheet materials and arising thermoelectric currents are exemplarily shown by an instantaneous measurement during blanking. An adequate material selection with regard to thermoelectric properties reduced adhesive wear to 22%. The obtained results improve the fundamental understanding of wear causing interactions.
