<p>The springback evaluation method pertaining to the present invention has: an intersecting plane setting step (S1) for setting at predetermined intervals a plurality of intersecting planes intersecting the shape of a press molded article; a cross sectional shape acquisition step (S3) for acquiring for each of the set intersecting planes the cross sectional shape of the press molded article; a cross sectional shape direction acquisition step (S5) for acquiring the orientation of each of the cross sectional shapes in each of the intersecting planes as the direction of the respective cross sectional shape; and a springback amount evaluation step (S9) for evaluating the springback amount by comparing the direction of the cross sectional shape relative the acquired standard shape and the post mold release shape in all the intersecting planes. The intersecting plane setting step (S1) the cross sectional shape acquisition step (S3) and the cross sectional shape direction acquisition step (S5) or a position specification point coordinates acquisition step (S7) are each performed for the standard shape and the post mold release shape of the press molded article.</p> |
