A method of forming a board into a curved panel, including: providing a cutting tool having a support portion and a cutting portion, the cutting portion having a first cutting edge, and a plurality of second cutting edges disposed adjacent each other and recessed relative to the first cutting edge by a defined offset dimension; placing a corrugated board on the support portion such that a b-facing-layer is disposed facing the support portion, and an a-facing-layer is disposed facing the cutting portion; advancing the cutting portion toward the board such that the first cutting edge cuts completely through both the a-facing-layer and the b-facing-layer of the board, and the plurality of second cutting edges cut completely through the a-facing-layer, but not completely through the b-facing-layer; and, retracting the cutting portion away from the support portion and removing the panel to facilitate further manipulation of the panel into the curved panel.

The present disclosure relates to methods of laser-leaching polycrystalline diamond (PCD), devices for performing such methods, and to laser-leached PCD and elements and drill bits containing laser-leached PCD.

A system and method for selectively removing tire material from the bead portions of a cured tire to reduce one or more harmonics of at least one uniformity parameter are disclosed. According to aspects of the present disclosure, tire material is selectively removed using a plurality of direct address commands. The direct address commands specify ablation parameters for discrete ablation segments at specific angular locations around the bead of the tire. The direct address commands are generated by analyzing the desired ablation pattern for the bead of the tire. The ablation device can then be controlled to selectively remove tire material in discrete ablation segments at identified addresses pursuant to the direct address commands to achieve the desired ablation pattern on one or more tracks along the bead portion of the tire using a single pass of the ablation device.

The invention relates to a Method for cutting a separator foil (41) for an electrode assembly for a battery cell, the separator foil (41) containing a polymer layer (45) and a ceramic layer (46), by dint of a laser beam (80), the laser beam (80) being emitted by an ultrashort pulse laser and consisting of ultrashort pulses of light, whereat the laser beam (80) propagates in a propagation direction (z) and is linear polarized in a vertical direction (x), and whereat the laser beam (80) is directed onto the separator foil (41) and is moved along the separator foil (41) in a cutting direction (s). The invention also relates to a separator foil (41) cut using the method according to the invention and a battery cell containing at least one such separator foil (41).

The automated trimming of an untrimmed plant stem comprises a device for transporting an untrimmed plant stem to an imaging stage, using a camera to capture at least one image of the plant stem, sending the at least one image to a central processor which creates a trim map which constructs a pattern for moving a cutting armature along the plant stem, and trimming the plant stem by cutting structure of the cutting armature to change the untrimmed plant stem to a trimmed plant stem.

An edible decoration is laser kiss cut from an edible decorating sheet by optically sensing at least one printed edible design on the edible decorating sheet relative to a laser cutting tool coordinate system and driving a laser along a circuit of cutting locations defined in the laser cutting tool coordinate system. The laser beam forms a separation channel by laser ablation of at least a portion of the edible decorating sheet at the cutting locations while leaving intact the non-adhesive releasable backing upon which the edible decorating sheet rests.

A method of machining a diamond includes using a pulsed laser. The diamond is placed in a container containing a transparent liquid. The liquid level is at least 100 microns above a surface of the diamond to be machined, and the transparent liquid can further contain a surfactant additive in an amount of at least 2% and 10% by mass. Next, a laser source is activated such that a laser beam with pulse durations of no longer than one microsecond at a repetition frequency of no more than 5 kHz is applied to the surface to be machined, and relative scanning is performed between the diamond and the laser source, cross-wise to the laser beam and axially in depth, with an amplitude and orientations that are determined by the shape to be machined in the diamond.

A method for manufacturing a cutting tool according to one embodiment is a method for manufacturing a cutting tool, the cutting tool including a base material and a diamond single crystal material fixed to the base material, the diamond single crystal material having a rake face, a flank face continuous with the rake face, and a cutting edge formed by a ridgeline serving as a boundary between the rake face and the flank face. The method for manufacturing a cutting tool according to one form of the present disclosure includes a flank face irradiation step of applying a laser to the diamond single crystal material along the cutting edge from a side of the flank face. The laser has a pulse width of 110.sup.12 seconds or less and a peak output of less than 1 W in the flank face irradiation step.

A method of manufacturing a strip of rubber having discontinuous reinforcer segments includes a conveying step in which a rubber strip is conveyed in a direction DC, and a cutting step in which reinforcers of the strip are cut. The cutting step includes localized heating of each reinforcer using a laser beam from a remote source. A cutting device useable to perform the cutting step includes a conveying device and a cutting head. The conveying device moves the strip in the conveying direction DC past the cutting head. The cutting head includes an emitter from which at least one laser beam is produced to cause localized heating of at least one reinforcer of the strip, in order to cut the at least one reinforcer into discontinuous reinforcer segments. The strip may be conveyed continuously or discontinuously, such that the strip may be moving or immobilized during the cutting step.

A method of forming one or more perforations, holes, or capillaries in a hydrogel material, hydrocolloid material, hydrogel adhesive or silicone adhesive comprising directing a focal point of a laser beam to a surface of the material or adhesive at one or more locations to form one or more perforations, holes, or capillaries having a selected diameter. The perforated hydrogel material or adhesive can be used in wound care dressings, wearable sensors, or devices intended to contact living tissue. The perforated material or adhesive may also be provided in contact with an exudate holding mechanism such as an open cell foam material to further increase the exudate absorbance of the hydrogel or hydrocolloid wound care dressing.
