<p>An electric discharge machine is provided with a gap servo control unit (3) for controlling the gap distance between an electrode (11) and a workpiece (12) while applying a prescribed voltage between the electrode (11) and the workpiece (12), and a jump control unit (2) for controlling a jump that allows the gap distance to be large temporally for a prescribed time or correspondingly to the machined state. The jump control unit (2) is provided with a jump locus generating section (1) for generating a smooth command locus having a frequency component within a prescribed frequency region not greater than the prescribed frequency or less than the prescribed frequency. The jump control unit (2) controls a jump by using the smooth command locus generated by the jump locus generating section (1).</p> |
