  • Publication number: 20140284311
    Abstract: The wire electric discharge machine determines whether machining is submerged machining or flushing machining. If the machining is the submerged machining, when a fluid level of working fluid is lower than a predetermined height, the wire electric discharge machine prohibits a machining power from being applied. Thus, it is possible to prohibit the machining power from applied in a state in which the working fluid is insufficient and the submerged machining cannot be appropriately performed, thereby preventing an electric shock due to contact with a wire electrode and machining parts of a workpiece and preventing the working fluid from scattering to the air, and improving safety.
