  • Patent number: 9364919
    Abstract: An apparatus and method are provided for laser deposition welding of powdery welding material. The powdery welding material is conveyed via a nozzle coaxial with respect to a laser beam directed in a focused manner with a constant focal length onto a processing region through the nozzle onto the processing region. Optical elements are arranged in a laser optical unit for the shaping and guidance of the laser beam. The laser optical unit is attached to a processing head and can be moved with the processing head parallel to the laser beam by a first drive. The plane of the focal point can thereby be changed with respect to the surface. The nozzle can be moved independently of the laser optical unit parallel to the optical axis of the laser beam by a second drive.

  • Patent number: 9335759
    Abstract: Semiconductor chips with curable out of specification measured values of an anneal-activated parameter are identified at a test step. A plurality of anneal plans are generated to include at least one of the identified semiconductor chips. A net yield improvement is calculated for each anneal plan. Each anneal plan includes the paths of a laser beam across the wafer to be irradiated, and optionally includes an azimuthal angle of the wafer as a function of time. The net yield improvement is the difference between an estimated yield improvement from selected target semiconductor chips for irradiation and an estimated yield loss due to collateral irradiation of functional semiconductor chips for each anneal plan. After simulating the net yield improvements for all the anneal plans, the anneal plan providing the greatest net yield improvement can be selected and utilized.

  • Patent number: 9278483
    Abstract: A selective layer melting or other additive layer fabrication method in which powdered material is fused by heating it with a pulsed laser, the pulses being modulated while the laser is traversing the substrate so as to control the thickness and/or width of the layer being formed. Initial layers of the fabrication structure may be formed more thickly than subsequent layers, e.g. by means of a CW laser, to reduce distortion. This aspect of the invention may be employed independently of the use of a pulsed laser to form the subsequent layers.

    Abstract: A method of operating a plasma arc torch system includes placing a work piece to be cut on a table of the plasma arc torch system, wherein at least a portion of the work piece has a planer surface facing away from the table. A plasma arc torch is positioned adjacent the planer surface of the work piece using a positioning apparatus, wherein the positioning apparatus has at least five degrees of freedom about which it can move the plasma arc torch relative the work piece for cutting the work piece on the table. The method further includes angling the torch relative the planer surface of the work piece such that the torch is held at an angle of between about 1 and about 4 degrees from perpendicular with the planer surface to back burn a produced kerf such that a kerf edge is perpendicular relative the planer surface of the work piece. Additionally, the planer surface of the work piece is calculated by contacting the work piece with the torch at least three times.

  • Patent number: 9044827
    Abstract: A direct metal deposition (DMD) process is stabilized by monitoring the temperature and the shape of the melt pool during deposition, applying a recursive least square (RLS) model estimation algorithm to adaptively identify process characteristics in accordance with the temperature and the shape of the melt pool, and delivering the process characteristics to a generalized predictive controller with input constraints to control the process. The process may be controlled by adjusting laser power or by adjusting the speed of the movement of the laser. In the preferred embodiment the temperature is monitored using a two-color pyrometer, and the shape of the melt pool is monitored by detecting the edge of the melt pool with a camera and/or photodetector.

    Abstract: A method for controlling the parallelism of first and second surfaces that define an optically resonant cavity is disclosed. The surfaces are separated by a first separation that is based on a support that holds the first surface relative to the second surface. The support comprises a first material and includes one or more regions in which the material stress of the first material is heat tuned to locally induce a stress gradient that results in a localized deformation. By controlling the locations and amounts of one or more localized deformation regions, the orientation of the first surface relative to the second surface is controlled.
