A processing method of processing a formed product by a punch press, includes a step of leaving a micro joint (D) connecting a workpiece (W) to a raw material (C) forming the formed product (B) at a time of forming a slit (S1, S2) in the workpiece (W) along an outer shape of the raw material (C); a step of forming the formed product (B) by bending the bending process portion (E) downward on the basis of a cooperation of an upper metal mold (1) and the lower metal mold (3); and a step of dropping the formed product by separating the connection between the formed product (B) and the workpiece (W) by the micro joint (D). <IMAGE> |
