  • Process for forming a firtree slot in a disc of a rotor of a gas turbine engine
    Patent number: 8567059
    Abstract: A process for forming a firtree slot in a disc of a bladed rotor assembly for a gas turbine engine may include making a first pass with a machining quill to form a rough profile of the firtree slot, making a second pass with an inclined machining quill having the shape of one of the finished side wall profile of the firtree slot and avoiding engagement with the other side, and making a third pass with an inclined second quill having the shape of the other of the finished side wall profile of the firtree slot and avoiding engagement with the other side, in order to provide a firtree slot for receiving and fixing the root of a blade.
