Abstract
1. Способ электроэрозионной обработки, при котором на электрод-инструмент наряду с силовыми подают поджигающие импульсы, амплитуду которых регулируют, отличающийся тем, что, с целью расширения технологических возможностей, величину амплитуды напряжения поджигающих импульсов устанавливают в зависимости от изменения профиля боковой поверхности детали и определяют из соотношения:где U - величина амплитуды напряжения поджигающих импульсов;K - коэффициент пропорциональности;φ(H) - функция, описывающая закон изменения профиля боковой поверхности детали;H - удаленность данной точки профиля от начала координат;D - поперечный размер профиля электрода.2. Способ по п.1, отличающийся тем, что, с целью повышения точности деталей за счет компенсации износа электрода-инструмента по боковым поверхностям, амплитуду напряжения поджигающих импульсов дополнительно увеличивают пропорционально уменьшению поперечного размера обрабатываемой полости.3. Способ по пп. 1,2, отличающийся тем, что дополнительно повышают величину рабочего тока пропорционально уменьшению поперечного размера обрабатываемой полости.4. Устройство для электроэрозионной обработки электродом-инструментом с пластинчатой рабочей частью, профиль которой эквидистантен профилю прошиваемой полости, снабженное схемой управления режимом обработки, отличающееся тем, что в него введена дополнительная пластина из токопроводящего материала с профилем, эквидистантным профилю рабочей части электрода-инструмента, установленная соосно рабочей части электрода-инструмента и изолированная от нее, причем указанная пластина электрически связана со схемой управления.1. Electro-erosion treatment method in which igniting pulses are supplied to the electrode tool along with power ones, the amplitude of which is regulated, characterized in that, in order to expand technological capabilities, the magnitude of the voltage of the ignition pulses is set depending on the change in the profile of the side surface of the part and determine from the relationship: where U is the magnitude of the amplitude of the voltage of the igniting pulses, K is the proportionality coefficient, φ (H) is a function describing the law of profile changing side to spine parts; H - distance of the profile point away from the origin; D - Profile elektroda.2 transverse dimension. The method according to claim 1, characterized in that, in order to improve the accuracy of the parts by compensating for the wear of the electrode tool on the side surfaces, the amplitude of the voltage of the igniting pulses further increase in proportion to the decrease in the transverse size of the cavity being processed. The method according to paragraphs. 1.2, characterized in that it further increases the value of the working current is proportional to the reduction in the transverse size of the cavity being processed. A device for electroerosive treatment with an electrode-tool with a lamellar working part, whose profile is equidistant to the profile of the pierced cavity, equipped with a control circuit for the processing mode, characterized in that an additional plate of conductive material with a profile equidistant to the profile of the working part of the electrode-tool is inserted, coaxially installed the working part of the electrode tool and isolated from it, and the specified plate is electrically connected with the control circuit.
