A wire electrode (4) is hung from an upper die guide (5) of a wire electric discharge machine toward a workpiece (7), a distance from a position where the wire electrode on the top surface of the workpiece is hung down to a top end position of a machined groove (23) formed by the electric discharge machining is calculated based on a commanded taper angle and the distance from the top surface of the workpiece to an upper die guide fulcrum position (6) of the upper die guide, and automatic wire connection is performed by moving an upper nozzle by the calculated distance (35). In this way, a wire connecting operation can be performed in the vicinity of the tapered groove. |
