  • Publication number: 20060141908
    Abstract: A metal machining apparatus for removal of metal from a workpiece, that employs a laser-targeted coolant nozzle to apply coolant fluid to a machining tool, such as a grinding wheel, to remove metal from a workpiece. The laser-targeted coolant nozzle has a coolant nozzle body having a flow passage for the coolant fluid, and a laser bore through which a visible laser can be inserted. The visible laser cooperates with a positioning feature on the nozzle body for visually positioning the coolant nozzle relative to the grinding wheel. When the laser is removed and replaced with a seal plug, the stream of cooling fluid passing through the flow passage can be directed accurately at the grinding wheel for improved workpiece grinding.

  • Publication number: 20050262683
    Abstract: A manufacturing cell having a plurality of work stations, where at least one of the work station comprises a metalworking machine, and where at least one metalworking machine is provided with a modular tooling apparatus. The modular tooling apparatus consists of a base having one or more attachment surfaces, and one or more inserts that can be inserted semi-permanently to the attachment surfaces. The attachment surface is typically a pocket in the surface of the base. The insert has a workpiece support feature that can support and/or secure the workpiece into the proper position and orientation for machining. The base, pockets and inserts are configured to provide a characteristic location and orientation for the workpiece relative to the base, and to the metalworking machine.

  • Publication number: 20050152758
    Abstract: A modular tooling apparatus for performing a metalworking operation on a workpiece or a family of workpieces. The modular tooling apparatus consists of a base having one or more attachment surfaces, and one or more inserts that can be inserted semi-permanently to the attachment surfaces. The attachment surface is typically a pocket in the surface of the base. The insert has a workpiece support feature that can support and/or secure the workpiece into the proper position and orientation for machining. The base, pockets and inserts are configured to provide a characteristic location and orientation for the workpiece relative to the base, and to the metalworking machine. The modular tooling apparatus permits machining a family of workpiece members that are related but different in detail, by inserting the insert member from the family of inserts to properly position and orient the corresponding workpiece member, without needing to change, disconnect, or move the base tooling.

  • Publication number: 20050132570
    Abstract: A method of using a machining assembly to machine a plurality of different turbine components that include a dovetail having a contoured profile. The method includes removably coupling a first set of retainers into the machining assembly, the first set of retainers include an upper portion having a profile that substantially mirrors a portion of the first dovetail, and a lower portion having a profile that substantially mirrors an opposite side of the first dovetail, coupling a first turbine component between the upper and lower portions such that the first turbine component is secured by the first set of retainers, coupling the machining assembly into a milling machine, and machining at least one seal groove into the dovetail of the first turbine component.

  • Publication number: 20050095962
    Abstract: A metal machining apparatus for removal of metal from a workpiece, that employs a laser-targeted coolant nozzle to apply coolant fluid to a machining tool, such as a grinding wheel, to remove metal from a workpiece. The laser-targeted coolant nozzle has a coolant nozzle body having a flow passage for the coolant fluid, and a laser bore. The laser bore forms an access opening in the outer surface of the nozzle body in through which a visible laser can be inserted. The laser bore provides a line of sight with the flow passage outlet. The visible laser can be inserted into the laser bore, and is configured so that the visible laser beam cooperates with a positioning feature on the nozzle body for visually positioning the coolant nozzle relative to the grinding wheel. When the laser is removed and replaced with a seal plug, the stream of cooling fluid passing through the flow passage can be directed accurately at the grinding wheel for improved workpiece grinding.
