摘要： The present disclosure provides a method for determining a hole completing in laser drilling of a hole in a near wall of an airfoil. The method includes drilling a hole in the near wall of the airfoil using a laser drill. The laser drill may move in a pattern relative to the airfoil. The method also includes determining when the drilling of the hole is complete based on a calculated time duration between successive breakthroughs of a laser from the laser drill through the near wall of the airfoil, or based on a calculated time duration since the latest breakthrough of the laser from the laser drill through the near wall of the airfoil.

摘要： A method for repairing one or more holes in a near wall of a component is provided. The method includes determining updated hole information, including an updated location, of a first hole in the near wall of the component. The method also includes directing a confined laser beam of the confined laser drill towards the near wall of the component at the updated location of the first hole to drill through a coating of the component extending over and/or positioned in the first hole. The method also includes sensing a characteristic of light reflected from the updated location of the first hole and determining the confined laser beam of the confined laser drill has drilled through a portion of the coating of the component extending over and/or positioned in the first hole based on the sensed characteristic of light.

摘要： A system for forming a passage in an airfoil includes a liquid-jet guided laser that generates a laser beam confined within a fluid column, and a purge medium supply that is fluidly coupled to an aperture of the airfoil. A purge medium flows from the purge medium supply in a flow direction that is substantially parallel to an inner surface of the inner cavity. A controller is configured to direct the liquid-jet guided laser to cut a first passage through the outer surface. A centerline of the passage forms an acute angle with respect to the purge medium flow direction. The first passage is formed at a first radial position that is radially distal to the aperture. A method for forming passages in an airfoil using the system described herein is also disclosed.

摘要： A method for drilling a hole in a component is provided. The method includes directing a confined laser beam of a confined laser drill towards a near wall of the component and sensing a first characteristic of light from the hole in the near wall of the component with a first sensor positioned outside the component. The method also includes sensing a second characteristic of light from the hole in the near wall the component with a second sensor. The second characteristic of light is different from the first characteristic of light. Additionally, the method includes determining a hole progress based on the sensed first characteristic of light and the sensed second characteristic of light.

摘要： A system for forming a cooling hole in an airfoil includes a liquid-jet guided laser. The liquid-jet guided laser generates a laser beam confined within a fluid column. The fluid column/laser beam is directed at an outer surface of the airfoil. The system also includes a purge medium supply that is fluidly coupled to an aperture of the airfoil. The purge medium supply provides a purge medium into an inner cavity of the airfoil. The purge medium flow is oriented to flow in a flow direction that is substantially parallel to an inner surface of the cavity. A cooling hole is formed in the airfoil and extends through the outer surface and penetrates the inner surface of the cavity. A centerline of the cooling hole forms an acute angle with respect to the purge medium flow direction. The system described herein provides a method for manufacturing an airfoil.

摘要： A method for drilling a hole in a component is provided. The method includes directing a confined laser beam of the confined laser drill towards a near wall of the component and sensing a characteristic of light directed along a beam axis of the confined laser beam away from the component with a sensor. The method also includes determining one or more operational conditions based on the characteristic of the light sensed with the sensor. The one or more operational conditions includes at least one of a depth of the hole being drilled by the confined laser drill and a material into which the confined laser beam of the confined laser drill is being directed. Such a method may allow for more appropriate control of the confined laser drill.

摘要： A method for manufacturing an airfoil is provided, the method including drilling a hole in a near wall of the airfoil using a laser drill and activating a back strike protection in a cavity of the airfoil. The method additionally includes detecting a breakthrough of a laser from the laser drill through the near wall of the airfoil and subsequently initiating a drilling subroutine, with the drilling subroutine including a continued operation of the laser drill. Such a method may provide for an improved hole, such as a cooling passage, in the airfoil.
