Abstract
A plurality of helical grooves are formed in a workpiece having a cylindrical shape. Each of grooves is divided into a first portion including an end portion on a first end side of the workpiece and a second portion including an end portion on a second end side of the workpiece. A method of manufacturing a screw rotor of a screw compressor includes attaching a first end of the workpiece to a holder of a machine tool, finishing the first portion of each of the plurality of helical grooves by cutting, detaching the workpiece from the holder, attaching a second end of the workpiece detached from the holder to the holder, and finishing the second portion of each of the plurality of helical grooves by cutting.
