Abstract: A process for manufacturing a single-piece blisk, including: using an abrasive water jet to cut a block of material, so as to create blade preforms extending radially from a disk, then milling the blade preforms.

Abstract: A process for manufacturing a single-piece blisk, including: using an abrasive water jet to cut a block of material, so as to create blade preforms extending radially outwards from a disk, while keeping material to form a connecting mechanism between directly consecutive blade preforms, the cutting being done such that the connecting mechanism approximately forms a ring at a radial spacing from the disk, connecting the blade preforms together at a radially inwards distance from their tips, and then removing the connecting mechanism.

Abstract: A process for manufacturing a single-piece bladed disk, including: using an abrasive water jet to cut a block of material, so as to create blade preforms extending radially outwards from a disk, while keeping material forming a connecting mechanism between at least two directly consecutive blade preforms, the connecting mechanism being at a radial spacing from the disk; then removing the connecting mechanism; then milling the blade preforms.

Abstract: A method to manufacture an integrally bladed rotor, including: cutting a block of material by an abrasive waterjet, undertaken so as to reveal blade preforms extending radially from a disk, while retaining the material forming a linking mechanism between at least two preforms of directly consecutive blades, wherein the linking mechanism is spaced radially from the disk; followed by removal of the linking mechanism.

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°.
