A method of developing a stamping die for a workpiece is provided, which includes the steps of stamping a workpiece in a current die. A measurement is made of the stamped workpiece to determine its profile. The profile is compared with the design intent workpiece to determine dimensional variance. If the variance is within predetermined limits, the development is complete. If the variance is beyond limits, a conceptual determination is made of the residual forces in the current die stamped workpiece when the current die stamped workpiece is restamped by a design intent die. This conceptual determination is carried out on a computer. From the determination of residual forces, a new current die is developed. The new current die then stamps the workpiece. The steps are repeated until the stamped workpiece profile is within predetermined limits.
A method of developing a stamping die for a design intent three-dimensional profile workpiece comprising the steps of:
A method of developing a stamping die as defined in claim 1 wherein an initial current die has a surface profile identical to the design intent profile of the workpiece.
A method as described in claim 1 wherein an initial current die is a die having a surface profile which has modifications from the design intent profile of the workpiece.
A method of developing stamping die is defined in claim 1, wherein the measuring of the current die stamp workpiece is performed utilizing an optical scanner.
A method as described in claim 1 wherein the measuring of the current die stamp workpiece to determine a three dimensional profile is performed utilizing a coordinate measurement machine.
