Summary:In a method for producing a sheet metal part, a sheet metal blank is rolled to have at least two regions of different material thickness to define a thick region and a thin region, with a thickness profile of the sheet metal blank extending in substantial symmetric relationship to a central plane of the sheet metal blank. The sheet metal blank is inserted into a forming tool having a punch and a die and a punch-proximal side of the sheet metal blank is contacted with a pressing cam formed on the punch. The sheet metal blank is formed into the sheet metal part by pressing the punch against the die and thereby forming an embossment by a die cam provided on the die on a die-proximal side of the sheet metal part.
