  • Patent number: 11817748
    Abstract: A method for constructing a lamination for a rotary electric machine includes forming an annular lamination from a ferrous core material having a first relative magnetic permeability. The lamination defines through-openings, e.g., for permanent magnets or conductors. Peripheral bridges of the core material extend between the through-openings and an outer or inner diameter surface of the lamination. The method includes diffusing an alloy material having a second relative magnetic permeability into the bridges to form austenitic bridges, with the second relative magnetic permeability being less than the first relative magnetic permeability. A rotary electric machine includes a stator and rotor. A vehicle includes a rotary electric machine connected to the battery pack and to road wheels, and having a rotor and/or a stator constructed in accordance with the method.

  • Patent number: 11806811
    Abstract: A method for producing a shaped sheet of wrapping, including a hollow portion and a perimetral edge that extends along a pre-set profile, is provided. The method includes laying a sheet of wrapping on a treatment surface having a forming cavity. The method includes forming the sheet of wrapping within the forming cavity so as to reproduce the shape of the hollow portion thereon, without subjecting the sheet of wrapping to deformation by stretching. The method includes cutting the formed sheet of wrapping along the pre-set profile for producing the perimetral edge and obtaining the shaped sheet of wrapping. In the method, the cutting step envisages the use of a laser beam according to a particular cutting mode.

  • Patent number: 11794283
    Abstract: A unitary adapter for attaching a cutting nozzle to a laser cutting head includes an inner cylinder made of ceramic, a conductive shield sintered to the outer sidewall of the ceramic cylinder, a threaded conductive holder (for accepting the cutting nozzle) mounted in an opening at one end of the ceramic cylinder, and a coaxial connector (for connection to external measuring equipment) attached to an opposite end of the ceramic cylinder. A pair of wires is formed to be embedded within the ceramic material and provide separate electrical connections between the coaxial connector and: (1) the threaded holder, and (2) the conductive shield. The various components are sintered to the ceramic body to form permanent attachments, creating a unitary structure less susceptible to the high levels of acceleration and elevated temperatures associated with the laser cutting process.

  • Patent number: 11794284
    Abstract: Disclosed are methods of manufacturing a workpiece fixture (10) and also a target material fixture (10), for use in precision manufacturing processes. A sheet material is supported on a generic material fixture (10) and the sheet material precision processed to form support blades (16, 18) for a target workpiece fixture (10). Each support blade (16, 18) has a support locus and interstices are positioned in the support loci where a target pattern and the support loci coincide. Thus, there are no unnecessary clearances between the workpiece support (10) and the workpiece. The interstices that are present are located only where necessary to reduce or eliminate any interference between the precision manufacturing process and the fixture (10), when it is used in a precision process involving the target pattern.

  • Patent number: 11780032
    Abstract: A control device controls a beam vibrating mechanism to vibrate a laser beam in a C-shaped vibration pattern in which a beam spot is moved from a first irradiation position at a front end in a cutting advancing direction to a second irradiation position at a rear side and displaced in an orthogonal direction to the cutting advancing direction, and is moved from the second irradiation position to a third irradiation position at a front end and displaced in the orthogonal direction to the cutting advancing direction, and movement from the first irradiation position to the third irradiation position via the second irradiation position, and movement from the third irradiation position to the first irradiation position via the second irradiation position are repeated. The control device performs control to cut the sheet metal by causing beam spots in the first to third irradiation positions to overlap one another.

  • Patent number: 11731303
    Abstract: A precut module with one or more profiling heads and/or circular saws may be provided upstream of a saw module. The precut module may be used to implement a portion of a cut that would otherwise be made by the saw module, thereby reducing the depth of cut required at the saw module. In some embodiments, profiling heads may be used to profile a block that is wider than a desired side board. The block may be cut from the workpiece and sent to the edger. This may provide the same or better wood volume recovery and/or throughput speed than profiling the side board or cutting the side board from a flitch. In some embodiments, cut patterns for the precut module and other machine centers may be calculated and/or selected based on a desired depth of cut at the saw module, desired throughput speed, wood volume recovery, and/or other parameters.

  • Patent number: 11717904
    Abstract: The durability and detection accuracy of a sensor unit may possibly decrease due to radiation heat generated from work pieces while they are welded together. A sensor device 1 includes a sensor unit 2, a housing case 3, and a shielding member 5. The sensor unit 2 is a device for measuring the shapes of the work pieces W or the distance to the work pieces W. The housing case 3 houses the sensor unit 2 and has formed therein a pass-through portion 36a for laser beam projection and a pass-through portion 36b for detection that pass a laser beam L1 from a laser beam projection unit 21 and a laser beam L2 directed to a detection unit 22, respectively. The shielding member 5 is attached to the housing case 3, and shields radiation heat directed toward the lower surface of the housing case 3 among radiation heat generated while the work pieces W are welded together. The shielding member 5 is made of a material with lower thermal conductivity than that of the housing case 3.

  • Patent number: 11712750
    Abstract: The present disclosure relates to a laser system for processing a material. The system may make use of a laser configured to intermittently generate a first laser pulse of a first duration and a first average power, at a spot on a surface of the material being processed, and a second laser pulse having a second duration and a second peak power. The second duration may be shorter than the first duration by a factor of at least 100, and directed at the spot. The second laser pulse is generated after the first laser pulse is generated. The first laser pulse is used to heat the spot on the surface of the material, while the second laser pulse induces a melt motion and material ejection of molten material from the melt pool.

    Abstract: A fixture used in the manufacture of an eyepiece, to cut the eyepiece to a particular shape, and a method of using the fixture to cut the eyepiece to have a desired shape. Embodiments are directed to a configurable fixture to align, hold, and protect a plastic sheet (e.g., a wafer) while a laser cutting apparatus is cutting one or more eyepieces out of the wafer. During the cutting, the fixture protects the eyepieces from reflected laser light by providing voids around the laser cutting lines, and by supporting each eyepiece near its perimeter. The fixture can be quickly rearranged for different eyepieces, different eyepiece shapes, and/or different plastic sheet sizes.
