Abstract
A method and system for flanging a metal part is provided to improve the final dimensions of the part to a desired shape. Residual stresses from flanging operations can distort a final shape of the metal part. This disclosure provides an initial flanging step in which metal gainers are formed into the metal during a first flanging step. The metal gainers provide an increased amount of metal at select regions. Then, during a next flanging step, the metal gainers are smoothened or removed during that flanging step while the metal is additionally bent. The metal gainers help combat the residual stresses and allow the flange to better take the desired shape.
