Изобретение относитс к электроэрозионной обработке материалов.The invention relates to the electrical discharge machining of materials.
Известен способ электроэрозионной обработки в токопровод щей среде разнопол рными импульсами, при котором в паузах между рабочими импульсами к эрозионному промежутку прикладывают импульсы напр жени обратного знака.The known method of electroerosive treatment in a conductive medium with opposite-polarity pulses, in which, in the pauses between the working pulses, voltage of opposite sign is applied to the erosion gap.
Однако в р де случаев помимо электроэроаионного процесса происход т электрохимические процессы с разложением воды. В результате выделени кислорода наблюдаетс интенсивное ржавление стальных изделий, а также деталей станка.However, in a number of cases, in addition to the electro-ionic process, electrochemical processes occur with the decomposition of water. As a result of oxygen evolution, intense rusting of steel products as well as machine parts is observed.
Цель изобретени - уменьшить интенсивность электрохимических процессов.The purpose of the invention is to reduce the intensity of electrochemical processes.
Полное устранение влени разложени воды может быть достигнуто, если добитьс равенства иулю за период среднего значени тока утечки, протекающего между электродом-инструментом и электродом-изделием поМимо разр дного канала.A complete elimination of the water decomposition phenomenon can be achieved if equality is achieved for the period of the mean leakage current flowing between the tool electrode and the work electrode of the discharge channel.
Это достигаетс тем, что среднее значение напр жени импульса обратного знака за период выбирают равным среднему значению напр жени на нагрузке от рабочего импуль2This is achieved by the fact that the average value of the voltage of a pulse of the opposite sign over a period is chosen equal to the average value of the voltage on the load from the working pulse 2
са, независимо от момента пробо эрозионного промежутка, т. е. должно соблюдатьс условие равенства средних значений за период импульса положительного и отрицательного напр жений.Sa, regardless of the moment of breakdown of the erosion gap, i.e., the condition of equality of the mean values over the period of the impulse of positive and negative stresses must be observed.
На фиг. 1 показана форма напр жени на эрозионном промежутке при единичных рабочих имлульсах, т. е. , на фиг. 2 - при ступенчатых импульсах или групповых импульсах , т. е. на фиг. 3 - при серии рабочих импульсов, т. е. Ь7+58+5э , Sii- -Si2 Si3-i-Sii.FIG. Figure 1 shows the form of stress on the erosion gap with single working impulses, i.e., fig. 2 - with step pulses or group pulses, i.e. in FIG. 3 — with a series of working pulses, i.e. b7 + 58 + 5 e, Sii-Si2 Si3-i-Sii.
