A stock inserted into a die is sandwiched between a punch and a knock-out, a predetermined pressing force is applied to the knock-out, and a pressing force larger than the sum of the pressing force of the knock-out and a pressing force for forming is applied to the punch to effect a forming work, whereby the forming accuracy can be enhanced and a final product can be obtained by going through only a slight finishing work.
