The increasing scarcity of energy and the resulting rise in energy prices significantly impact operating costs in production facilities. This trend is particularly pronounced in sheet-metal stamping, where the use of higher-strength steels for lightweight construction leads to higher process friction, which increases the cost pressure on already tight margins due to unpredictably high tool wear. Due to the closed tool design, direct condition monitoring of sheet-metal stamping tools is not feasible. This dissertation addresses these challenges by presenting a systematic approach for...
