<P>PROBLEM TO BE SOLVED: To solve the problem that an offset value varying when increasing a discharge electric current by correcting a specific kind of electric machining condition must be adjusted. <P>SOLUTION: Offset adjustment data comprising continuous data indicating correlation between a plate thickness and a variation width of an offset are generated by an approximation method on the basis of the necessary minimum number of measurement data in advance and stored in a storage device. The variation width of the offset varying when a specific kind of electric machining condition is corrected so that a discharge electric current is increased is obtained from the offset adjustment data. The obtained variation width of the offset is divided by a predetermined first constant to find an adjustment value of an on-time of a machining condition. When a reminder is generated in the division, it is divided by a predetermined second constant to find an adjustment value of a servo reference voltage of the machining condition. The on-time and the servo reference voltage are adjusted on the basis of the adjustment values. <P>COPYRIGHT: (C)2013,JPO&INPIT |
