Weight reduction in an AA2017 aluminum alloy part through the gas forming process of a blank with a variable thickness

Lighter and lighter products are required by aerospace automotive sectors in order to reduce fuel cost carbon dioxide emissions and, allow using green energy propulsion, such as the electric one. In lighten parts aluminium alloys, which have a high strength weight ratio, most commonly used metal materials. They manufactured through plastic deformation processes often tailored blanks. This work focuses attention on semi-finished obtained subtract-ing material machining; they further class of this work, design simple (almost hemispherical) alloy sheet component AA2017 is analysed, with help finite element analysis. weight; circular blank was used, characterised variable initial profile thickness instead conventional disc constant thickness. Given that more uniform final determined, enhanced resistance characteristics product achieved. Therefore, workpiece will be characterized reduction about 8% compared analogous ob-tained from
