  • Compound electromachining
    Patent number: 8161641
    Abstract: A preform includes an airfoil stub and a dovetail hub. The hub first undergoes electrochemical discharge machining to form a rough dovetail. The airfoil stub undergoes electrochemical machining to form an airfoil. The rough dovetail then undergoes electrochemical discharge machining to form a rough tang. The rough tang is finish machined to form a dovetail extending from the airfoil in a unitary rotor blade.
    Type: Grant
