1. A machining method of a wire discharge machine, comprising:
a processing of forming and machining a claw part on at least one of a first machining path of a machining groove and a second machining path of a dividing line for dividing a core that forms an inner part of a workpiece separated by the machining groove, wherein the claw part has a triangular cross section, a hook cross section, a convex cross section, or a trapezoidal cross section; and
a processing of separating the core from the workpiece by dividing at the dividing line.
