摘要:
A method for processing a workpiece with a processing device which has a processing head which can be moved at a defined speed and distance from a surface of the workpiece, the method comprising at least partially detecting a surface topography of the workpiece to be processed, determining a minimum desired operating distance of the processing head from the workpiece with reference to the detected surface topography of the workpiece and a trailing spacing of the processing head associated with the defined speed, and processing the workpiece with the processing head at the established minimum desired operating distance of the processing head from the workpiece.
摘要:
An apparatus for holding a plate-like material during a separation process. The apparatus includes a separating device that is movable, during the separation process, in a first axial direction that is transverse to a second axial direction that the plate-like material is conveyed in during the separation process. The apparatus also includes first and second transport tables. The first transport table has a first contact surface and the second transport table has a second contact surface. The first contact surface and the second contact surface are spaced apart by a gap along which the separating device is movable. The apparatus also includes at least one holding device that is operable hold the plate-like material relative to the first and second contact surfaces such that the plate-like material is movable along the first and second contact surfaces. The holding device is configured to support the plate-like material such that a first surface of the plate-like material, on which a cutting beam of the separating device impinges, faces toward the first and second contact surfaces during the separation process.

A plate workpiece processing tool includes a first tool portion and a second tool portion. The first and second tool portions are arranged along an application axis in spaced relation to each other such that a plate workpiece can be disposed therebetween. The tool also includes two or more processing devices that are carried by the first tool portion, and one or more counter-devices that are carried by the second tool portion. The processing devices are rotatable, relative to the first tool portion, about a first rotational axis that extends perpendicular to the application axis and are arranged to follow each other along an axis extending perpendicularly to the application axis. The processing devices and the one or more counter-devices are selectively alignable to form a plurality of alternative device pairings for processing plate workpieces therebetween.

A tool includes first and second tool parts that move toward one another, at least one processing device provided on the first tool part, and at least two counter devices provided on the second tool part. The processing device and the counter devices are rotatable relative to one another about at least one positioning axis, and the counter devices are aligned relative to one another along a direction of relative rotational movement of the processing device and the counter devices. The processing device and a first counter device are allocated to one another by at least a first defined processing parameter, and the processing device and a second counter device are allocated to one another by at least a second defined processing parameter. The first processing parameter is different than the second processing parameter.

A device for analyzing a beam profile of a laser beam includes a carrier plate, a plurality of first temperature-sensitive measuring elements, in particular diodes, which are arranged in a preferably matrix-like arrangement on a first side of the carrier plate at a plurality of measuring locations, and a plurality of second temperature-sensitive measuring elements, in particular diodes, which are arranged in another preferably matrix-like arrangement on a second side of the carrier plate. One of the first measuring elements is arranged in each case opposite one of the second measuring elements and is thermally coupled to the first measuring element using strip conductors which extend through the carrier plate. Such a device can be included in a laser processing machine and used in an associated method for analyzing a beam profile of a laser beam.

A method for processing workpieces with a laser processing machine including a laser processing head having a nozzle receiving member configured to receive a laser nozzle. The method includes holding a workpiece on a workpiece support plane of a workpiece support, transferring a laser nozzle between a nozzle magazine of a nozzle changing device located at a first side of the workpiece support and a nozzle receiving member of the laser processing head located at a second side of the workpiece support such that the laser nozzle is assembled on or disassembled from the nozzle receiving member, and moving the laser nozzle through a through-opening defined in the workpiece support along a transverse direction to the workpiece support.
