    Abstract: A plasma cutting system includes a power supply that outputs first and second plasma cutting currents. A torch is connected to the power supply and includes a first cathode that receives the first plasma cutting current, a first electrode and swirl ring, a second cathode that receives the second plasma cutting current, and a second electrode and swirl ring. The torch simultaneously generates a first and second plasma arcs from the electrodes. A gas controller is configured to separately control a flow of a first plasma gas to the first swirl ring and a flow of a second plasma gas flow to the second swirl ring. A torch actuator moves the torch during cutting, and includes a motor having a hollow shaft rotor for rotating the torch during cutting. A motion controller is operatively connected to the torch actuator to control movements of the torch during cutting.

    Abstract: A method for determining operating parameters to process a workpiece using a manufacturing processing system including a plasma arc gouging torch. The method includes positioning a plasma arc gouging torch at a location relative to a workpiece and determining a start point and an end point for each gouging path based on the location and a gouge profile. The method further includes using the gouging profile to determine first operating parameters for the plasma arc gouging torch for a first gouging path and determining second operating parameters for the plasma arc gouging torch for a second gouging path based on the gouge profile and the first gouging path. The second operating parameters include at least one of a second torch speed or a torch offset. The method also includes using at least one of the first or second operating parameters to process the workpiece with the plasma arc gouging torch.

    Abstract: A bed mesh combination device includes a feeding assembly movable in a first direction, two groups of welding cutter assemblies and a welding head assembly oppositely arranged in a second direction. The feeding assembly can lay a spring string on the welding cutter assembly, the welding cutter assembly includes a plurality of welding cutters extending in a third direction, the welding cutters of a same group are arranged at intervals along the first direction, the welding cutters of different groups are staggered in the first direction, the two groups of welding cutter assemblies respectively correspond to first and second welding positions of the spring string. The welding cutter assembly can push the spring string to move in the second direction and can be close to or far away from the spring string in the third direction. The welding head assembly includes an ultrasonic welding head and a first driving member.

    Abstract: A method of fabricating a grinding tool includes providing an abrasive particle, and cutting the abrasive particle with a laser beam so that the cut abrasive particle has four tips adjacent to one another, a cavity of a generally cross shape extending between the four tips, and a material discharge surface at an end of the cavity. The laser beam is applied along a plurality of parallel first cutting lines and a plurality of parallel second cutting lines, the second cutting lines intersecting the first cutting lines, at least the first cutting lines being grouped into a first, a second and a third region, the second region being located between the first and third regions, a number of cutting passes repeated along each of the first cutting lines in each of the first and third regions increasing as the first cutting line is nearer to the second region, and the laser beam repeating a plurality of cutting passes along each of the first cutting lines in the second region.
