摘要
A precision forging method includes arranging a metal material in a die cavity so that a distal end surface of a wall portion of the metal material is opposed toward a stopper and a bottom portion of the metal material is opposed toward a punch. Further, the precision forging method includes moving the punch, which includes a cutting blade on an edge of a working end surface, in the die cavity to cut part of the wall portion thickness-wise with the cutting blade and cause shear deformation in the cut portion.
