Abstract:Electrical discharge machining (EDM) is an important process technique to machine the cowled integral impeller, and the processing quality and efficiency are directly influenced by the design of electrode and its feeding path. The design of electrode and its feeding path is very complicated because of the narrow and twisted channel between two blades. A synchronous design method of electrode and its feeding path is put forward to get a maximum stiffness electrode with complete forming surface corresponding to the blade's surface, and its implement method is also studied based on UG software. The design efficiency, machining accuracy and stability are all improved significantly. A cowled integral impeller's EDM experiment is verified. © 2017, Editorial Board of Acta Armamentarii.
