Изобретение касаетс электрофизических способов обработки, в частности способа электроэрозионной обработки.The invention relates to electrophysical processing methods, in particular, the method of EDM.
Известны способы электроэрозионной обработки , по которым импульсы тока имеют пик либо в начале, либо в конце и.мпульса, либо одновременно в начале и в конце.Known methods of EDM processing, in which the current pulses have a peak either at the beginning or at the end of an impulse, or at the same time at the beginning and at the end.
Однако такие способы не позвол ют достигнуть высокой производительности и минимального износа электрода-инструмента одновременно .However, such methods do not allow achieving high productivity and minimal wear of the electrode tool at the same time.
Целью изобретени вл етс увеличение производительности процесса и стойкости электрода-инструмента.The aim of the invention is to increase the productivity of the process and the durability of the electrode tool.
По предложенному способу токовый пик сдвигают но времени по отношению к началу импульса на 15-45% от его общей длительности .According to the proposed method, the current peak is shifted over time, relative to the beginning of the pulse, by 15-45% of its total duration.
На фиг. 1 показана форма импульса; на фиг. 2 - типична зависимость производительности от положени токового пика (в относительных единицах) дл пары медь - сталь 45.FIG. 1 shows the pulse shape; in fig. 2 — typical performance dependence on the position of the current peak (in relative units) for a copper – steel 45 pair.
На фиг. 1 по оси абсцисс отложено врем , по оси ординат - величина рабочего тока. Пик тока расположен в первой половине рабочего импульса (15-45% от его общей длительности ).FIG. 1, time is plotted on the abscissa, and the value of the operating current is on the ordinate. The peak current is located in the first half of the working pulse (15-45% of its total duration).
На фиг. 2 по оси абсцисс отложено врем сдвига токового пика, а по оси ординат - стойкость электрода-инструмента.FIG. 2, the time of the current peak shift is plotted along the abscissa, and the resistance of the tool electrode is plotted along the ordinate axis.
Предмет изобретени Subject invention
Способ электроэрозионной обработки импульсами тока, каждый из которых имеет пик, отличающийс тем, что, с целью увеличени производительности процесса и стойкости электрода-инструмента, токовый пик сдвигают но времени по отношению к началу импульса на 15-45% от его общей длительности .The method of electroerosive processing with current pulses, each of which has a peak, characterized in that, in order to increase the productivity of the process and the durability of the electrode tool, the current peak is shifted in time relative to the beginning of the pulse by 15-45% of its total duration.
