Claim 7:
8. An electrochemical machining method based on an electrochemical machining device for a blisk using electrode array according to claim 1, comprising the following steps:
(a) mounting the blisk on a rotary table concentric with the inner ring-shaped base;
(b) starting an electrolyte circulating system, and feeding an electrolyte to a machining gap between each of the inner ends of ones of the cathode rods and the blisk;
(c) starting a power supply comprised in the electrochemical machining device to electrify cathode rods and the blisk;
(d) when the outer ring-shaped rotating ring rotates clockwise, driving a connecting rod comprised in the electrochemical machining device to rotate relative to the outer ring-shaped rotating ring, pushing the cathode rods to rotate and feed by rotating the connecting rod, and when the power supply is switched on, electrochemically dissolving the blisk to form three-dimensional contours of a group of cascade channels;
(e) after the group of cascade channels are completely machined, stopping feeding electrolyte, cutting off the power supply, enabling the outer ring-shaped rotating ring to rotate counterclockwise, and enabling the cathode rods to return to initial positions;
(f) rotating and indexing the blisk, and repeating steps (a) to (e) until remaining cascade channels of the blisk are completely machined; and
(g) after the group of cascade channels and the remaining cascade channels of the blisk are both completely machined, switching off the power supply and the electrolyte circulating system.
