Method of manufacturing by electric discharge machining an impeller for centrifugal rotating machine |
摘要 |
A method for manufacturing an impeller of a centrifugal rotating machine that is approximately disk-shaped and in which flow passages are formed between a plurality of blades and disposed in a radial manner from the inner circumferential side to the outer circumferential side, provided with a first flow passage formation step that forms a first region on the outer circumferential side within the flow passage by inserting an electrode of a shape fitting to the flow passage with the electric discharge machining method from the outer circumferential side of the disk-shaped body having an outer shape of an impeller, and a second flow passage formation step that forms a second region on the inner circumferential side within the flow passage from the inner circumferential side of the disk-shaped body.
