A method for forming a sheet metal component using an electric current passing through the component is provided. The method can include providing a single point incremental forming, the machine operable to perform a plurality of single point incremental deformations on the sheet metal component and also apply an electric direct current to the sheet a metal component during at least part of the forming. The direct current can be applied before or after the forming has started and/or be terminated before or after the forming has stopped and can reduce the magnitude of force required to produce a given amount of deformation, increase the amount of deformation exhibited before failure and/or reduce any springback typically exhibited by the sheet metal component.
