Wire electric discharge machine capable of machining various surfaces

摘要

A wire electric discharge machine according to the present invention includes a multijoint robot including a wire crossing mechanism for crossing a wire electrode on its tip end, a robot controller for controlling the multijoint robot, a numerical controller for controlling the wire electric discharge machine, and a transmission unit for transmitting a coordinate position when the multijoint robot is driven and controlled to move the wire crossing mechanism from the robot controller to the numerical controller, and the numerical controller synchronizes a position of each shaft of the wire electric discharge machine with a movement of the wire crossing mechanism with reference to the coordinate position transmitted by the transmission unit.
