The objective of this work was to establishthe basis for an economical and effectivedesign for the extension of the shape changingcapacity of parts made of aluminumsheet through the implementation of heatsupportedforming. Thereby, underlying parametersof industrial serial productionwere taken into consideration. In the focusof the investigations suitable heating processesfor heat-supported forming were considered.Thereupon, basic research had tobe carried out in order to apply inductivesurface heating. This heating method hasbeen researched up to this point not extensively.In addition to the knowledge gainedregarding the setup and application of surfaceinductors, heat resistant lubricantswere characterized to define the processwindow for the heat-supported forming ofthe aluminum alloy EN AW-5182. In orderto apply the process under the conditions ofindustrial series production, a specifiedprocedure must be established in which theheat treatment layout can be determinednumerical for any sheet metal parts.
