  • Manufacturing method of compressor impeller and compressor impeller
    Patent number: 10113554
    Abstract: An object is to provide a manufacturing method of a compressor impeller which produces a small post-cutting residual strain. A compressor impeller is formed by cutting a workpiece. The manufacturing method of a compressor impeller includes: a workpiece-fixing step of fixing a workpiece W on the supporting pedestal 3; and a cutting step of cutting inter-vane regions R and forming a plurality of vane sections B1, B2 and so on with intervals between one another in the circumferential direction of the workpiece W while pressing the workpiece. The cutting step includes selecting one of following steps. In the first cutting step, when successively cutting the plurality of inter-vane regions R1, R2 and so on disposed continuously in the circumferential direction of the workpiece, adjacent one of the inter-vane regions is avoided as often as possible.
