A substrate-cutting stage includes a main stage and a dummy stage spaced apart from each other with a cutting region interposed therebetween and that support a substrate. The main stage supports a first portion of the substrate, the dummy stage supports a second portion of the substrate, and the cutting region overlaps a to-be-cut portion of the substrate disposed between the first and second portions.

A method of processing structurally identical workpieces using a numerically controlled workpiece processing apparatus includes processing a first workpiece according to a first desired tool path specified for a tool of the numerically controlled workpiece processing apparatus by closed-loop controlling a working distance between the tool and the workpiece to achieve a defined desired distance, such that when processing the first workpiece, the tool is moved along a distance-controlled actual tool path. The method further includes optimizing the first desired tool path for a second workpiece based on the distance-controlled actual tool path of the first workpiece to provide a second desired tool path and processing the second workpiece according to the second desired tool path.

A method of welding a first metal plate and a second metal plate that is thicker than the first plate, by a laser beam. The first plate and the second plate are disposed to overlap one another in a thickness direction. In a first laser irradiation step, the laser beam is emitted at the first plate, to form an initial nugget including a front-side nugget portion in the first plate, a back-side nugget portion in the second plate and having a diameter smaller than a diameter of the front-side nugget portion, and an annular flat surface portion existing between the front-side nugget portion and the back-side nugget portion. In a subsequent laser irradiation step, the laser beam is emitted again at the initial nugget after the initial nugget is solidified, thereby increasing the diameter of the back-side nugget portion.

A plasma cutting system for measuring or monitoring the voltage between a plasma torch and the material being cut to determine a voltage or voltage signature and comparing that measurement against predetermined values to indicate that an initial pierce of the material is complete, and based on the measurement, moving the torch or the material to a different location for additional cutting. The system further provides a Fix Drawing Tool, which will automatically detect and fix gaps or overlaps in a drawing that are very difficult to find visually. These gaps and overlaps become a problem when trying to make a proper toolpath because a CAM program requires a clean, closed shape. The system also provides a Dynamic Corner Looping system, which automatically adjusts with the feed-rate and accelerations of the toolpath and plasma machine, eliminates unwanted dross, sharpens corners and minimizes material loss. A pendant tethering system is also disclosed for managing control of a CNC machine remotely. Additional disclosed functionality includes a data collection system, a manual hand wheel with 3D simulation and a multiple fabrication head management system.

A laser beam machine includes: a processor to machine a workpiece as the processor moves; a saddle that holds the processor, and moves the processor in a Y direction by moving in the Y direction along a guide extending in the Y direction; a cross rail on which the saddle is placed, the cross rail moving the saddle and the processor in an X direction by moving in the X direction along a guide extending in the X direction; and a bed on which the cross rail is placed via the guide extending in the X direction. The bed includes bases and beams, one of longitudinal end portions of the base is joined to a side surface of the beam, one of longitudinal end portions of the beam is joined to a side surface of the base.

A method for removing a plastics coating from a block of food, in particular a whole cheese, operates with the following steps: the block of food, in particular the whole cheese with its plastics coating is fed to the method. A laser beam is then directed onto the plastics coating of the block of food. Herein the output of the laser which emits the laser beam is adjusted so that a removal of the plastics coating takes place by separation of a region of the plastics coating and/or by erosion or vaporisation of the plastics coating. A device for removing a plastics coating from a block of food, in particular a whole cheese, comprises a transport apparatus for the block of food and a laser apparatus for applying a laser beam to the block of food.

A substrate processing apparatus includes a holder configured to hold a combined substrate; a peripheral modifying device configured to form a peripheral modification layer to an inside of a first substrate along a boundary between a peripheral portion and a central portion; an internal modifying device configured to form an internal modification layer to the inside of the first substrate along a plane direction; a holder moving mechanism configured to move the holder in a horizontal direction. The peripheral modifying device radiates laser light for periphery to the inside of the first substrate while moving the holder to perform eccentricity correction. The internal modifying device radiates laser light for internal surface without performing the eccentricity correction at least at a center portion of the inside of the first substrate.

A hairpin welding method welds wire ends of at least two copper wires, arranged flush next to one another, to one another by a laser beam. The laser beam is generated with a beam cross section that impinges on the wire ends at an end side and has a round core region and a ring region surrounding the round core region. A ratio of an external diameter of the ring region to a diameter of the core region is between 7:1 and 2:1. A ratio of a laser power in the core region to a laser power in the ring region is between 10:90 and 70:30.

A laser processing apparatus includes a support portion, a laser processing head, a vertical movement mechanism, a horizontal movement mechanism, and a controller. The controller controls starting and stopping of emission of a laser light from the laser processing head based on rotation information in a state where a focusing point is positioned at a position along a circumferential edge of an effective region in a target, while rotating the support portion, to perform a circumferential edge process for forming a modified region along the circumferential edge of the effective region in the target.

A bonding structure of an electrical contact, a bonding method of the electrical contact and a battery module are provided. The bonding structure of the electrical contact includes an electroconductive part and an electrode sheet welded to the electroconductive part. The electrode sheet is a first metal material, and the electroconductive part is a second metal material. A welding track is formed on an interface formed by combining the electrode sheet with the electroconductive part. The welding track is a mixture of the first metal material and the second metal material. The welding track substantially has no overlap. In addition, the welding track includes a moving path, and a lateral path of performing a wobble movement or an oscillation movement on lateral sides of the moving path.
