Abstract
An electric discharge machining method for machining a core pin for a resin die using an electric discharge machine including a secondary electrode for molding of a round-bar shaped machining electrode. The electric discharge machining method includes a step of executing generating electric discharge machining for cutting out a schematic shape of the core pin from a work with the machining electrode, a step of transferring a shape element of the secondary electrode to the machining electrode and molding the machining electrode for diesinking electric discharge machining, and a step of applying the diesinking electric discharge machining to the work cut out in the schematic shape of the core pin using the machining electrode molded for the diesinking electric discharge machining.
