Abstract: A system includes a processor configured to receive a design model for a blade that has multiple diffuser holes. The processor is also configured to generate multiple points along an edge of each of the multiple diffuser holes. Further, the processor is configured to generate multiple vectors and each of the multiple points includes a corresponding vector. Moreover, each of the multiple vectors originates at the corresponding vector's corresponding point. Further, the processor is configured to apply the multiple vectors to inspect one or more manufactured diffuser holes.

Abstract: A head assembly for a liquid jet guided laser system is disclosed having a coupling unit removably disposed to a laser focus optic module of the laser system. The coupling unit has a nozzle assembly removably connected to the coupling unit. The nozzle assembly has a liquid jet nozzle and a nozzle cap. The nozzle cap has a plurality of axial assist gas conduits and static assist gas conduits in fluid communication with an assist gas source extending through the nozzle cap body to individually transport assist gas to axial exit ports and static exit ports positioned to exhaust assist gas proximate the liquid jet. At least a portion of the plurality of axial assist gas conduits are partitioned from fluid communication with the liquid jet hole. A lateral movement assembly can be configured between the laser focus optic module and coupling unit.

Abstract: A method for cutting passages in an airfoil using a liquid-jet guided laser beam includes positioning a frustoconical tip of the liquid-jet guided laser at a first X, Y and Z location that is defined with respect to the airfoil and at a first standoff distance of greater than 5 mm and less than 20 mm from an outer surface of the airfoil. The method also includes generating a laser beam confined within a fluid column via the liquid jet guided laser, wherein the laser beam is aimed at the outer surface. The method further includes monitoring for breakthrough of the laser beam through an inner surface of an inner cavity of the airfoil, shutting off the laser beam once breakthrough is detected and repositioning the frustoconical tip at a second X, Y and Z location and at a second standoff distance. A system for cutting a passage in an airfoil is also disclosed herein.

Abstract: 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 first hole position on a near wall of the component. The method also includes sensing a characteristic of light within a cavity defined by the component. The near wall is positioned adjacent to the cavity and the sensor is positioned outside the cavity. The method also includes determining a first breakthrough of the confined laser beam through the near wall the component at the first hole position based on the light from within the cavity sensed with the sensor.

Abstract: 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.
