ABSTRACT:
A method of determining springback in metal forming with a fluid cell press through establishing a computational formulation to determine bend angle and compensated die radius based on factors of geometry of the part being formed, material properties of the sheet material and the forming process, and computing additional iterations of springback until a specific tolerance between the formed part angle and the desired part angle are reached.
