    Abstract: A computer aided technology system includes a processor. The processor may receive a design model for a blade that has multiple diffuser holes. Also, the processor may derive a hole position and a vector for each of the multiple diffuser holes. In addition, the processor may translate the hole position to a machine coordinate system to create a translated hole position. Moreover, the processor may generate a manufacturing program based on the translated hole position and the vector. The blade includes a stator vane, a rotor vane, or a combination thereof. Further, the blade is included in a compressor, a gas turbine engine, or a combination thereof.

    Abstract: Various embodiments include methods and related systems for laser-assisted casting. Some embodiments include a method including: performing laser ablation on a preliminary wax casting model to form a modified wax model including at least one additional feature absent from the preliminary wax casting model; coating the modified wax model to form a mold shape around the modified wax model; removing the modified wax model to leave a casting mold including the at least one additional feature; forming a shape from a casting material using the casting mold having the at least one additional feature; and scanning the modified wax model to image the at least one additional feature after the performing of the laser ablation.

    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.

    Abstract: A system for manufacturing an airfoil includes an unfocused laser beam and a first fluid column surrounding the unfocused laser beam to create a confined laser beam directed at the airfoil. A sensor inside the airfoil detects penetration of the confined laser beam through the surface of the airfoil. A method for manufacturing an airfoil includes confining an unfocused laser beam inside a first fluid column to create a confined laser beam, directing the confined laser beam at a surface of the airfoil, and penetrating the surface of the airfoil with the confined laser beam. The method further includes detecting penetration of the confined laser beam through the surface of the airfoil.

    Abstract: A method of monitoring an operation status of a confined laser cutting tool includes emitting light in the form of laser beams from a laser source. The method includes using a nozzle to form a confining column composed of a liquid. The method further includes forming a confined laser beam, the confined laser beam defined by the confluence of the laser beams and the confining column. The method also includes sensing a characteristic of the confined laser beam with a sensor. The method further includes determining the operation status of the confined laser cutting tool based on the sensed characteristic of the confined laser beam. The method also includes deactivating the laser source when the sensed characteristic of the confined laser beam reaches a predetermined threshold. The method may also include providing an operator notification after deactivating the laser source.
