A method for producing a diffusion cooling hole extending between a wall having a first wall surface and a second wall surface includes forming a cooling hole inlet at the first wall surface, forming a cooling hole outlet at the second wall surface, forming a metering section downstream from the inlet and forming a multi-lobed diffusing section between the metering section and the outlet. The inlet, outlet, metering section and multi-lobed diffusing section are formed by laser drilling, particle beam machining, fluid jet guided laser machining, mechanical machining, masking and combinations thereof.

Manufacturing methods for multi-lobed cooling holes

Aspects of the disclosure are directed to processing a component. A first coating is removed from a substrate of the component, the substrate including a first hole. Subsequent to removing the first coating from the substrate, a second coating is applied to the substrate, where a portion of the second coating at least partially blocks the first hole. Subsequent to applying the second coating to the substrate, the portion of the second coating is removed to generate a second hole through the second coating. The removal of the portion of the second coating creates a bore in the second coating that provides a clearance from an edge of the first hole on a surface of the substrate that interfaces to the second coating.

Laser clearance of coating

A refractory metal core (RMC) finishing method according to an exemplary aspect of the present disclosure includes, among other things, performing a plurality of finishing operations on a plurality of RMC samples, analyzing one or more properties of at least a portion of the plurality of RMC samples and selecting a combination of finishing operations for generating an RMC having desirable properties for manufacturing a part free from defects.

Refractory metal core finishing technique

An exemplary method of manufacturing an electrical discharge machining electrode includes, among other things, immersing at least a portion of an electrode base in a fluid, and electroplating an electrode coating containing diamond to an electrode base.

A zero clamp force fixture assembly may comprise a body comprising a locating surface and a side, a neck extending away from the side of the body, a zero force clamp coupled to the neck, and a universal locating feature coupled to the locating surface. The neck may taper towards an interface with the zero force clamp. The zero force clamp may comprise an upper jaw and a lower jaw.

Zero clamping force conforming fixture

A cutting tool comprising a tool body comprising a shank and a cutter opposite the shank, the body defining a length from a shank end to an end face opposite the shank end, a central axis extends along the length of the body; at least one tooth having a cutting edge, the cutting edge extending along the tooth from the shank to the end face; a flute formed adjacent the at least one tooth; at least one cooling channel formed in the tooth proximate the at least one cutting edge, the at least one cooling channel having an elongated cross sectional shape with an elliptical portion and a circular portion opposite the elliptical portion, wherein the elliptical portion is located proximate the cutting edge.

Internal cooling passages for rotating cutting tools

A coolant distributor comprising a head having a plurality of ports, each of the ports being fluidly coupled to a flow control valve. A cap is demountably coupled to the head. The cap comprises at least one fixed nozzle fluidly coupled to at least one port. A controller is coupled to the flow control valve, wherein the controller is configured to actuate the flow control valve to pass a cooling fluid through the at least one fixed nozzle to direct the cooling fluid to at least one predetermined cutting region of a machine tool and work piece proximate the coolant distributor.

Automated interchangeable coolant distributor

A method is provided for inspecting at least one aperture of a component with curable material and an inspection system. At least a portion of the curable material is injected into the aperture. The curable material conforms to at least a portion the aperture and subsequently cures and forms a mold of at least a portion of the aperture. The mold is removed from the aperture. At least a portion of a geometry of the mold is compared to at least a portion of a geometry of a reference model for the aperture using the inspection system.

Inspecting one or more apertures of a component using moldable material

Systems and methods are disclosed herein for adding surface features to grinding wheels. A laser may be directed substantially perpendicular to a grinding surface of a grinding wheel. The laser may be pulsed and may ablate material from the grinding surface. The laser may move relative to the grinding wheel in order to ablate shaped surface features into the grinding surface.

Methods for modifying and adding features on grinding wheel surfaces

An example electrical discharge machining electrode assembly includes an electrode base and an electrode coating containing diamond that is electroplated to the electrode base.

Systems and methods are disclosed herein for dressing and trueing grinding wheels. A laser may be directed substantially tangential to a grinding surface of a grinding wheel. The laser may be a continuous wave laser and may ablate material from the grinding surface. The laser may move relative to the grinding wheel in order to ablate shaped surface profiles into the grinding surface.

Systems and methods for dressing grinding wheels

A method of non-destructively inspecting an article includes scanning an article to produce a computerized three-dimensional representation of an internal feature of the article. A measurement characteristic of the internal feature is then generated from a plurality of cross-sections through the computerized three-dimensional representation of the internal feature. The measurement characteristic is then used to determine whether the internal feature meets a design criterion.
