    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 laser machining apparatus includes a laser nozzle for supplying an assistive gas to remove undesirable materials and applying a laser beam at an angle, which is inclined with respect to a surface of a workpiece, a sputter blocking jig disposed over a region of the workpiece that is irradiated with the laser beam, so as to lie across directions in which the laser beam is scattered, and for blocking sputtered particles that are generated from the surface by the applied laser beam, and a joint connecting the laser nozzle and the sputter blocking jig to each other. The joint moves the laser nozzle and the sputter blocking jig in synchronism with each other.

    摘要： A component is provided and includes a substrate comprising an outer and an inner surface, where the inner surface defines at least one hollow, interior space. The component defines one or more grooves, where each groove extends at least partially along the outer surface of the substrate and has a base and a top. The base is wider than the top, such that each groove comprises a re-entrant shaped groove. One or more access holes are formed through the base of a respective groove, to connect the groove in fluid communication with the respective hollow interior space. Each access hole has an exit diameter D that exceeds the opening width d of the top of the respective groove. The diameter D is an effective diameter based on the area enclosed. The component further includes at least one coating disposed over at least a portion of the surface of the substrate, wherein the groove(s) and the coating together define one or more re-entrant shaped channels for cooling the component. A method for manufacturing the component is also provided. A method for manufacturing a component is also provided, where the groove and the access hole(s) are machined as a single continuous process, such that the groove and the access hole(s) form a continuous cooling passage.

    摘要： In the case where the workpiece (1) is processed, the laser beam is S-polarized by an optical modulator (7). Thus, the laser beam is mainly diverted toward a workpiece (1) by a polarizer (6). An optical path through which the laser beam passes is caused to have a high light converging ability with respect to a target spot by an optical device (9). In the case where the workpiece (1) is not processed, the laser beam is P-polarized by the optical modulator (7). Thus, the laser beam is mainly diverted to a beam damper (10) side by the polarizer (6). However, the workpiece 1 is irradiated with the laser beam having leaked from the polarizer (6). An optical path through which the laser beam passes is caused to have a low light converging ability with respect to the target spot by the optical device (9).

    摘要： A new material processing apparatus using a short-pulsed, high-repetition-rate visible laser for precision micromachining utilizes a near diffraction limited laser, a high-speed precision two-axis tilt-mirror for steering the laser beam, an optical system for either focusing or imaging the laser beam on the part, and a part holder that may consist of a cover plate and a back plate. The system is generally useful for precision drilling, cutting, milling and polishing of metals and ceramics, and has broad application in manufacturing precision components. Precision machining has been demonstrated through percussion drilling and trepanning using this system. With a 30 W copper vapor laser running at multi-kHz pulse repetition frequency, straight parallel holes with size varying from 500 microns to less than 25 microns and with aspect ratios up to 1:40 have been consistently drilled with good surface finish on a variety of metals. Micromilling and microdrilling on ceramics using a 250 W copper vapor laser have also been demonstrated with good results. Materialogroaphic sections of machined parts show little (submicron scale) recast layer and heat affected zone.
