Localisation of damage zones with respect the final part in forging process for different geometric parameters

Abstract : The important criterion to obtain a good forged piece is the correct filling and the damage. A good filling means that the contour of the rough forged piece contains the contour of the final shape. If the damage occurs in zones that will be machined we consider that a good forged piece has been obtained. The goal is to differ between a correct and a defected rough forged depending on the obtained form of the rough forged and the location of the damage.
