  • Patent number: 11982196
    Abstract: 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.
    Type: Grant

  • Patent number: 10678206
    Abstract: A system includes a laser-line imaging subsystem to measure a feature. The laser-line imaging subsystem includes a laser to project a laser-line, and a digital video camera mounted at an angle with respect to an axis of said laser to obtain an optical image of the laser-line. A control subsystem is operable to compute three-dimensional coordinate points via triangulation of an intersection between the laser-line and the optical image of the laser-line, the three-dimensional coordinate points data used by the control subsystem to calculate predictive airflow through the workpiece with respect to the volume of the machined holes.

  • Patent number: 9052707
    Abstract: An exemplary component manufacturing method includes scanning a first surface of a component to determine a location of pocket surfaces of the first surface. The method machines apertures in the component from a second, opposite surface of the component. The apertures each have a cooling air inlet within one of the pocket surfaces and a cooling air outlet within the first surface.
