Fully automated machining apparatus optimization for electric discharge machining apparatus
 An electric discharge machining apparatus capable of automatically optimizing the machining stabilizing condition including set voltage of machining pulse, duty factor of the pulse, electrode raising period and working fluid pressure, and hence capable of being full-automated. Each machining stabilizing condition is successively changed within a predetermined range and set when the maximum effective discharge generation rate is obtained. Spark machining is effected on the basis of the set value.
