PURPOSE:To automatically further accurately correct a moving distance adequate for the machining condition in accordance with a change of the various electrical condition, by providing a theoretical circuit which sets and controls the various electrical condition in an electric discharge machined part. CONSTITUTION:Many machining programs are previously stored in a memory device 11a. That is, a machining requirement such as a quantity of electrodes, presence of oscillating machining, presence of a pitch feed, oscillating method and machined surface roughness of a work 2 at its machining finish or the like is provided, and the machining program is prepared by combination of this machining requirement. The various electrical condition in electric discharge machining, being set to this machining program, determines the various condition of machining speed, surface roughness and consumption ratio of the electrode or the like. |
