  • Method of making a gas turbine engine diffuser
    Patent number: 7114255
    Abstract: A method of machining a plurality of intersecting bores in an object, the method comprising steps of machining a first bore, plugging the first bore, machining a second bore so as to intersect the first bore, and unplugging the first bore.
    Type: Grant
    Filed: November 26, 2003
    Date of Patent: October 3, 2006
    Assignee: Pratt & Whitney Canada Corp.

  • Method of making a gas turbine engine diffuser
    Patent number: 6760971
    Abstract: A method of machining a plurality of circumferentially spaced bores in an object, each of the bores extending generally tangentially and inwardly and being positioned in the object so as to generally asymmetrically intersect two adjacent bores, comprises the steps of: providing an object; determining a plurality of bore positions generally around a circumference of the object; machining a first bore and performing at least one subsequent machining operation on the first bore to substantially complete the first bore; machining a second bore immediately adjacent to the completed first bore, wherein the second bore is machined so as to intersect the completed first bore, and performing at least one subsequent machining operation on the second bore to substantially complete the second bore; sequentially machining a remaining plurality of bores except a final bore, wherein each said bore is machined so as to intersect an immediately adjacent completed bore; and machining the final bore immediately intermediate the
