  • Patent number: 10376989
    Abstract: An assembly and method of reducing discoloration of a foam material resulting from laser processing the material comprising an assembly configured for positioning below the material being processed and for directing air into open cells of the open-cell foam material to pressurize the material during laser processing. The assembly comprises an air delivery mechanism comprising one or more apertures for an air chamber positioned directly below the material travel path. Aligning the one or more apertures with the axis of the laser beam and its focal point when the material is positioned above the one or more apertures and pressurizing or filling of the open cells with air in the direct vicinity of the target area reduces processing related discoloration of the material. The cells are laser processed concurrently with pressurization thereby substantially reducing settling of debris and smoke on the material and reducing discoloration.

  • Patent number: 9676062
    Abstract: Process for producing a line of weakness in a cover element comprising at least one slit. This slit is produced through a plurality of machining cycles in which a pulsed laser beam is guided in each instance over the cover element along an imaginary line so that the energy of the laser pulses is introduced into the cover element. The slits are produced in two segments. More energy is introduced over the machining cycles in the first, comparatively short segments than in the second, comparatively long segments. The residual wall below the slits decreases with each machining cycle until the first residual wall segment thickness in the first segment is so small that energy portions transmit through the first residual wall segment and are detected by a sensor arrangement arranged downstream. Accordingly, the first residual wall segment thickness is detected, and inferences can be drawn from this about the second residual wall segment thickness.

  • Patent number: 9138913
    Abstract: Methods, devices, and systems for ultrashort pulse laser processing of optically transparent materials are presented, with example applications in scribing, marking, welding, and joining. For example, ultrashort laser pulses create multiple scribe features with one pass of the laser beam across the material, with at least one of the scribe features being formed below the surface of the material. Slightly modifying the ultrashort pulse laser processing conditions produces different types of sub-surface marks. When properly arranged, these marks are clearly visible with correctly aligned illumination through either light scattering or light reflection and nearly invisible without illumination. Transparent material other than glass may be utilized. A method for welding transparent materials uses ultrashort laser pulses to create a bond through localized heating.

  • Publication number: 20150129688
    Abstract: Microfluidic flow-through elements and methods for forming and using the same, particularly, low cost, easily sterilized, disposable microfluidic flow-through elements may include an orifice region suitable, for example, for fluid jet formation (such as in a droplet sorter or flow cell) or sample injection or hydrodynamic focusing (such as in a non-droplet flow cytometer). Laser drilling, for example laser ablation, may be used to form an orifice region extending through an orifice wall section of a base substrate. The base substrate may be unitarily-formed by injection molding a polymeric material. The orifice region may be advantageously configured to form a predetermined geometry by controlling the characteristics of the ablating beam.

  • Publication number: 20150034603
    Abstract: Components, such as turbine blades or vanes, are formed to a desired shape and dimensions by ablation machining a work piece surface. Recast layer material created on the work piece surface during the ablation machining is subsequently removed by fluoride ion cleaning (FIC). Exemplary ablation machining methods include laser machining and electric discharge machining (EDM). The work piece material may include superalloys commonly used for fabrication of turbine blades or vanes, which are susceptible to recast layer formation during EDM or laser machining. Post ablation FIC recast layer removal is easier than known methods, such as mechanical grinding, secondary EDM machining of the layer at lower speeds and/or current intensity, or chemical etching processes. Ablation machining processes can be optimized for speed and efficiency without regard for recast layer avoidance, with knowledge that the recast layer will be subsequently removed by the complimentary FIC process.
