In a wire cut electric discharge machine, a discharge quiescent time OFFr is controlled to be longer than a reference discharge quiescent time OFFs when machining a circular arc corner portion having a circular arc radius R that is smaller than a reference circular arc radius R0. For example, OFFr=OFFsxR0/R is satisfied. By controlling the discharge quiescent time in this manner, the machining acc...

A change in the thickness of a workpiece is detected based on energy (e.g., number of pulses of a pulse current) input from a machining power source unit to a machining gap. If the thickness change is detected, a machining condition is adjusted (e.g., a discharge quiescent time is made longer than a predetermined discharge quiescent time) so that the energy input from the machining power source un...
