    摘要: An apparatus for controlling a trajectory along which a tooling positioner system moves tooling for machining multiple features of the same type in a component includes a first tooling trajectory having an entry velocity at a time when the tooling begins machining a first feature and an exit velocity at a time when the tooling completes machining of the first feature. A second tooling trajectory has an entry velocity at a time when the tooling begins machining a second feature and an exit velocity at a time when the tooling completes machining of the second feature. The entry and exit velocities of the second tooling trajectory are different from the respective entry and velocities of the first tooling trajectory. Methods for controlling a trajectory are also taught.

    摘要: The embodiments disclosed herein provide systems and methods for correcting a head-to-head offset in a laser machining system with two or more processing heads. A focusing lens is associated with each processing head, and is configured to receive an incident laser beam along an incident beam axis of propagation. The incident beam axis of propagation is offset from the primary axis of the focusing lens. The focusing lens is further configured to rotate about the incident beam axis of propagation in order to steer the incident laser beam's path with respect to a workpiece.

    摘要: A method and apparatus to improve image quality in images captured via monochromatic cameras using multi-wavelength lighting. A contrast optimization algorithm determines which particular wavelength among those available is most suitable to maximize contrast. The quality of the image can be further improved through active noise cancellation by determining the lighting schemes that provide maximum and minimum contrast between a target and a background. The elimination of image texture data (i.e., noise) is then accomplished through pixel-by-pixel division of the maximum by the minimum contrast image. Alternatively, images obtained using at least two wavelengths can be algebraically combined for noise reduction. The resulting composite image can be fed into any known target identification algorithm.

    摘要: A process and apparatus neutralizes a warp effect resulting from a build up of micro strains caused by machining a part with a long wavelength laser. The part to be machined is pre-stressed in an opposite direction of a warp stress due to machining using a fixture for holding the part without yielding any other features in the part. The part is machined while held in the pre-stressed position in the fixture.

    摘要: Systems and methods cut trenches of multiple widths in a material using a single pass of a laser beam. A first series of laser pulses cut a work surface of the material at a first cutting speed using a first spot size. In a transition region from a first trench width to a second trench width, a second series of laser pulses sequentially change spot sizes while gradually changing from the first cutting speed to a second cutting speed. Then, a third series of laser pulses continue to cut the work surface at the second cutting speed using a second spot size. The method provides for increased depth control in the transition region. A system uses a selectively adjustable optical component in the laser beam path to rapidly change spot size by adjusting a position of a focal plane with respect to the work surface.
