In this type of zero-less molding, the shape of the mold (C) is the amount by which the workpiece 2 is partially drawn in (in the figure, L++
L2) is different. This is because the pressing of the workpiece 2 changes depending on the force, etc., and is an important point in determining the quality of the molding. Particularly, in the limit drawing, wrinkles and tears occur depending on the amount by which the workpiece 2 is drawn.

のである。Therefore, when pressing the workpiece 2 during processing of a non-defective product, a signal corresponding to the drawing of the workpiece 2 according to the force and the pressure of the wrinkle presser plate 3 is sent, and when pressing each workpiece, a signal corresponding to the force and the displacement of the measuring stylus 5a corresponding to the part 4 is sent. The measured value is measured in advance by the device 5 and stored in the calculation unit 6 or the like. By sequentially comparing the data based on the displacement of the workpiece 2 measured during actual machining with the data during machining of the above-mentioned non-defective product in the calculation unit 6, the pressing force of the workpiece 4 is determined according to the deviation. The workpiece 2 is processed by individually controlling the feedback.
