Изобретение относитс к электрофизическим методам обработки материалов; и, в частности, касаетс способа экстремального регулировани рабочих Параметров электроэрозионного процесса .This invention relates to electrophysical methods for processing materials; and, in particular, concerns the method of extreme control of the working parameters of the EDM process.
Известен способ экстремального регулировани межэлектродного промежутка при электроэрозибнной обработке.The known method of extreme regulation of the interelectrode gap during electro-erosive processing.

Автоматический поиск максимума производительности по этому способу основан на вычислении разности двух замеров количества импульсов перемещени электрода-инструмента за два равных интервала времени. При этом из накопленных за первый интервал показаний вычитают показани , полученные за второй, и коррекцию настройки станка, например межэлектродного промежутка, осуществл ют по знаку полученной разности 1 .The automatic search for maximum performance by this method is based on calculating the difference of two measurements of the number of pulses moving an electrode tool over two equal time intervals. In this case, the readings obtained for the second are subtracted from the accumulated for the first interval of readings, and the adjustment of the machine setting, for example, the interelectrode gap, is carried out according to the sign of the obtained difference 1.
Недостаток этого способа состоит, в том, 4to по знаку полученной разности можно определить только знак следуюпрй коррекции про (Межутка. Величина коррекции при этом остаетс неизвестной.The disadvantage of this method is that, by the sign of the difference obtained, one can only determine the sign of the next correction correction pro (Interwire. The magnitude of the correction remains unknown.
Мала величина коррекции приводит к уве ,личению времени поиска максимума; производительности , а больша величина коррекции - к колебани м электрода-инструмента и, как следствие этого, к короткому замыканию между электродом-инструментом и изделием.A small correction value leads to an increase in the search time for the maximum; performance, and a large amount of correction - to the oscillations of the electrode-tool and, as a consequence of this, to a short circuit between the electrode-tool and the product.
Целью изобретени вл етс уменьшение времени поиска максимальной производительности электроэрозионного станка, путем определени знака и абсолютной величины коррек10 ции межэлектродного промежутка.The aim of the invention is to reduce the search time for the maximum performance of the EDM machine, by determining the sign and the absolute value of the correction of the interelectrode gap.
Поставленна цель достигаетс тем, что в ювестном способе взамен двух, периодически говтор ющихс измерений кбличества импупь- ,. сов перемещени электрода-инструмента за два This goal is achieved by the fact that in the well-known method instead of two, periodically speaking, measurements of the number of imputations,. moving the electrode tool in two
15равных , периодически повтор ющихс интервала времени, производ г однократное измерение трех значений скорости перемещени электродаинструмента при трех значени х межэлектродного промежутка, одновременно определ ют эти 15 equal, periodically repeating time interval, producing a single measurement of three values of the speed of movement of the electrotool with three values of the interelectrode gap, simultaneously determine these
