Abstract: FIELD: metal working, in particular, electric discharge machining, mainly when moving wire is used as electrode. SUBSTANCE: the device for control of electric discharges at electric discharge machining has a firing and operating generators with a control input that are parallel connected to the spark gap. The current transducer is connected to the output of the firing generator. The input of the solver with the operating discharge current analyzer and current threshold element is connected to the second input of the current transducer. The threshold element output is connected to the control input of the operating generator. The operating generator is furnished with an operating pulse length control unit, whose input is connected to the solver output. With the use of the firing generator auxiliary voltage pulses are applied between the electrode- part and electrode-tool, exceeding the operating pulse voltage at least by ten times. In this case the probability of operating discharge in very high. The appearance of operating discharge is registered by measuring the current in the spark gap by means of the current transducer and operating discharge current analyzer of the solver. When an operating discharge occurs, a signal via the threshold element is fed to the control input of the operating generator, which applies the operating voltage pulse to the spark gap. The magnitude of energy of the operating pulse is by an order of magnitude greater than that of the auxiliary pulse. From the solver output the signal is also applied to the input of the operating pulse length control unit. The pulse discharge duration is varied, depending on the strength of discharge current in the spark gap. EFFECT: facilitated procedure. 3 cl, 2 dwg
