Over the past decade OEMs have evolved aerospace structural designs to even larger monolithic structure for manufacturing and weight savings. In order to support OEM advanced designs, Alcoa has also evolved forging technologies including advanced alloys, modeling software, design techniques, processing paths, and concurrent engineering to produce such new large forgings in relatively short lead times and with minimal residual stresses. In addition, machine shops have made significant advances in speed and quality for machining these large forgings utilizing state of the art equipment and processing methods to drive down cost. This presentation highlights today’s advances in large part development from OEM design to alloys to forging design and processes to machining for final OEM sub-assembly.
