To keep an electric discharge state in an electric-discharge machining device constant, an electric-discharge machining control device includes: a machining power supply that applies a pulsed voltage to a minute gap between an electrode and a workpiece that are arranged to oppose to each other with a predetermined gap therebetween to generate electric discharge; a state amount detector that detects an inter-electrode voltage in the minute gap between the electrode and the workpiece; an electrode-vibration-state detection unit that detects an amplitude of the inter-electrode voltage obtained by the state amount detector; an adjustment-factor setting unit that sets a factor by which an inter-electrode average voltage obtained by the state amount detector is to be multiplied, based on an amplitude of an inter-electrode voltage obtained by the electrode-vibration-state detection unit; and an evaluation-voltage setting unit that sets an evaluation voltage based on the factor outputted from the adjustment-factor setting unit. |
