Abstract
Set feed speed is lowered when a short circuit is detected in a range within which machining is unstable, the range starting from the point at which discharge is detected after machining starts from a machining start point, thus control is carried our according to a machining rate, thereby preventing successive occurrence of short circuits. When machining proceeds beyond the unstable range, the lowered feed speed is returned to the normal feed speed.
