Abstract: A method of manufacturing a blisk comprises the steps of cutting a disk to a rough shape comprising a hub with a plurality of blade blanks projecting radially therefrom, machining each blade blank by tangential milling using a tool with a rotation spindle perpendicular to the radial direction to make repeated radial passes, the tool being turned through a facet angle with respect to the disk between each pass. Each blade blank is thus milled to a blade having faceted surfaces. Preferably, the width of each facet is smaller that 5 mm, and adjacent facets subtend angles smaller than 5°, or even more preferably smaller than 3°.
