Method for machining complex cavity through electric spark machining technology

According to the method for machining the complex cavity through the electric spark machining technology, due to the fact that the chip removal capacity of the position where the flushing channel density is high is good, the loss of the electric spark machining electrode at the position is low, and due to the fact that the chip removal capacity of the position where the flushing channel density is low or no flushing channel is poor, the loss of the electric spark machining electrode at the position is high. According to the method, the distribution density of flushing channels on the end face of the electric spark machining electrode is controlled, so that the loss of all parts of the electric spark machining electrode with the planar end face is controlled, and then the needed cavity is naturally formed according to the influence of the distribution density of the flushing channels on the loss of the electric spark machining electrode. And after one-time machining is completed, the next cavity can be machine
