Summary:The impeller machining method comprises the following steps that A, a cylindrical blank is taken, the blank is clamped and fixed to a milling machine, a blade-shaped arc line, an inner hole and a blade are milled under the condition that a workpiece is clamped at a time, the blade-shaped arc line is an envelope line of the outer edge of a series of step faces, and the inner hole is coaxial with the central axis of the blank; b, the workpiece is clamped and fixed to a lathe, and the design shape from the impeller back to the bottom face of the impeller is machined through turning; c, the workpiece is subjected to heat treatment; d, the workpiece is clamped and fixed to a milling machine, and the blade is subjected to finish milling; and E, the workpiece is clamped and fixed to a lathe, and the molded line of the impeller is subjected to finish turning. According to the impeller machining method, a more concise machining process path is used for machining the workpiece, the clamping frequency is reduced, and th
