Abstract
Drawing of the sheet metal parts is always accompanied by an undesired phenomenon known as springback. Springback occurs after the part is set free of the constraints – forming forces, tools – and leads to a shape of the final part different from the nominal ones. The knowledge of the factors that influence this phenomenon is useful for the accurate design of the forming processes and forming tools. The present paper performs an experimental analysis of the factors that influence the springback phenomenon in the case of the hemispherical drawn parts made from metal sheets.
