Abstract: A guide pipe provided along a movement path of a wire electrode between a direction change pulley and a winding device and guiding the wire electrode has antistatic properties. A gas-liquid mixed fluid is supplied into the guide pipe. A suction nozzle passes between a pair of rollers of the winding device and is directly or indirectly connected to an outlet side of the guide pipe. The suction nozzle suctions the gas-liquid mixed fluid in the guide pipe and a tip of the wire electrode by a suction device and captures the wire electrode. The captured wire electrode is wound by the winding device.

Abstract: The disclosure provides a machining program generating device of a wire discharge machine, a machining program generating method, a wire discharge machining system and a machined object manufacturing method. The machining method of the wire discharge machine of the disclosure includes: a processing of forming and machining a claw part on at least one of a machining path of a machining groove and a machining path of a dividing line for dividing a core that forms an inner part of a workpiece separated by the machining groove; and a processing of separating the core from the workpiece by dividing at the dividing line.

Abstract: A wire electric discharge machining apparatus includes: a processing tank, a lower-side wire guide assembly, a lower arm, a direction changing pulley, a winding roller, and a conveying device. The conveying device comprises a high-pressure jet flow generator and a suction pipe. The high-pressure jet flow generator is provided between the direction changing pulley and the winding roller on a side of a front end of a lower arm, and spouts a high-pressure jet flow toward a direction of the winding roller so that a wire electrode is guided only by a restraining force of the high-pressure jet flow and sent flying to the direction of the winding roller with the high-pressure jet flow. The suction pipe is provided on an exit side of the winding roller, and sucks and captures a tip of the wire electrode sent by the high-pressure jet flow.
