BLISK PRODUCTION METHOD AND BLISK INTERMEDIATE PRODUCT

摘要

A method for manufacturing a blisk (10) includes an intermediate product molding step of molding a blisk intermediate product (18) including a circular disk-corresponding part (20), a plurality of rotor blade-corresponding parts (22), and bridges (24) each connecting a front edge 22a of one of each pair of the rotor blade-corresponding parts (22) adjacent to each other and a rear edge (22b) of the other one of the rotor blade-corresponding parts (22). The method for manufacturing the blisk (10) further includes a disk finishing step of cutting the disk-corresponding part (20) so as to finish the disk-corresponding part (20) into the disk (12) in a product form, and a rotor blade finishing step of cutting each bridge (24) so as to finish the respective rotor blade-corresponding parts (22) into the respective rotor blades (16) in a product form.
