A processing machine for workpiece processing includes a cutting head that produces a cutting beam directed toward a workpiece, and a beam-catching device for receiving a discharge of the cutting beam from an underside of the workpiece during processing of the workpiece. The beam-catching device includes a housing defining an opening that opens toward the cutting beam and a beam-catching space adjacent the opening, the cutting beam discharging from the underside of the workpiece during the processing of the workpiece and entering the beam-catching space of the housing through the opening. The beam-catching device also includes at least one nozzle on at least one wall section of the housing, the nozzle feeding a fluid jet as a free jet to the beam-catching space in such a way that the at least one fluid jet crosses the cutting beam.

The invention relates to a device for supporting sheet-like materials for at least one separating process in the sheet-like materials, with at least one jet cutter device which may be displaced in the Y-direction during a separation process, with a first and second support surface together forming a support table for supporting the sheet-like material and with a jet trapping device, arranged between the first and second support surfaces and provided to be able to be displaced in the X-direction. The first and the second support surfaces are made from a flexible material forming part of at least one enclosed chamber, filled with a gas under pressure.

The invention relates to a method and a device () for producing a multi-layered three-dimensional component (). In a first step, a layered geometrical structure is formed, said structure consisting of at least two webs () of an at least high temperatures-resistant material. In a second step, an at least partly material connection is produced between the individual webs of the entire layered structure by means of at least one thermal treatment.

The invention relates to a process for producing a shaped body by selective laser melting, in which a shaped body is built up from pulverulent metallic material using CAD data of a model, in which a powder layer is applied using an applicator unit, and in which the applied powder layer is fixed to a layer below it using a focused laser beam, in which process the powder layer is levelled to a desired layer thickness as a result of a levelling device passing over the shaped body at least once, and during the levelling elevations that project above the desired layer height of the applied powder, of the layer which was last melted by the laser beam are uncovered by the levelling device.

A machine for the multi-stroke, continuous slotting of plate-shaped workpieces and especially sheet metal plates is described. A slotting tool () and the workpiece are movable in a forward direction relative to each other in a gate-cutting function and in at least one subsequent slot cutting stroke. This is followed by a return movement in the opposite direction () over a return length (A) that corresponds at a maximum to the length of the previously laterally cut slot. This is followed by a cross-cutting stroke in which the strip of material () that was laterally cut in the gate-cutting function and the minimum of one subsequent slotting stroke is severed at a distance from the point of its connection to the remaining workpiece. The slotting tool () is driven by a cam drive with a drive control, a return-drive system with a return-drive control and a forward-feed drive system with a feed-drive control. These control devices serve to control the slotting tool (), the return-drive and feed-drive systems of the machine tool.

A method and machine for the multi-stroke, continuous slotting of plate-shaped workpieces and especially sheet metal plates are described. As part of a method for the continuous multi-stroke slotting of plate-shaped workpieces, a slotting tool () and the workpiece are moved in an advance direction relative to each other in a gate-cutting function and is at least one subsequent slot cutting stroke. This is followed by a return movement in the opposite direction () over a return length (A) that corresponds at a maximum to the length of the previously laterally cut slot. This is followed by a cross-cutting stroke in which the strip of material () that was laterally cut in the gate-cutting function and the minimum of one subsequent slotting stroke is severed at a distance from the point of its connection to the remaining workpiece. A machine tool for performing this method incorporates a slotting tool () that is driven by a cam drive with a drive control, a return-drive system with a return-drive control and a forward-feed drive system with a feed-drive control. These control devices serve to control the slotting tool (), the return-drive and feed-drive systems of the machine tool for the implementation of the method described.
