System, method, and computer program product for aiding optimization of die assembly shape for plasticity manufacturing

摘要

In order to realize improving dimensional accuracy of a plastic workpiece and realize reducing a production cost and shortening time duration of manufacture, a computer comprises an initial die assembly shape calculating function to calculate a die assembly shape for the plastic workpiece according to a predetermined designed shape of said plastic workpiece; a workpiece shape calculating function to calculate the shape of the plastic workpiece to be manufactured with the initial die assembly shape considering a manufacturing condition of the plastic workpiece; a shape comparing function to compare the calculated shape of the plastic workpiece and the designed shape of the plastic workpiece; a workpiece-redesigning function to calculate a new designed shape of the plastic workpiece according to a result of the comparison; and a die assembly reshaping function to calculate a new die assembly shape according to the new designed shape of the plastic workpiece.
