Abstract: A method for cutting at least one workpiece from a metal sheet includes arranging a metal sheet on a support of a laser cutting machine, and directing a laser beam onto the metal sheet along an outline of the workpiece. The metal sheet is cut through in a main region of the outline. At least one connecting portion, which has a height that is less than a thickness of the metal sheet, remains in at least one connection region of the outline between the workpiece and an adjoining part of the metal sheet. The method further includes removing the at least one workpiece and the adjoining part connected thereto from the support, and separating the at least one workpiece from the adjoining part.

Abstract: In a method for laser fusion cutting in particular a plate-shaped workpiece, preferably with a thickness D of at least 1 mm, a laser beam and a cutting gas, in particular nitrogen, at a cutting gas pressure are directed at the workpiece surface by a convergent cutting nozzle. The laser power is at least 6 kW and the cutting nozzle has a nozzle end face on the workpiece side. A distance A between the nozzle end face and the workpiece surface during the cutting operation is 2 to 8 mm. The cutting nozzle has a nozzle channel with a diameter dD at the nozzle end face on the workpiece side of 1.5 to 4 mm. The cutting gas pressure before emergence from the cutting nozzle is 15 to 30 bar. This makes it possible to achieve high productivity along with a reduced risk of collision, i.e. higher process reliability.

Abstract: A sorting apparatus for sorting workpieces of a workpiece sheet includes a support region with support elements for placing the workpiece sheet thereon. At least one sorting opening for the workpieces to fall through is formed between adjacent support elements. The sorting apparatus further includes a collection region arranged below the support region and having at least two collection compartments for collecting the workpieces, a guide region arranged between the support region and the collection region and having at least one guide element for guiding the workpieces falling through the at least one sorting opening to the collection compartments, and an adjustment device for adjusting the collection compartments relative to the at least one guide element and/or for adjusting the at least one guide element relative to the collection compartments such that, via the at least one guide element, workpieces are selectively fed to a respective collection compartment.

Abstract: A method for cutting machining of a plate-shaped workpiece, including determining the position of the support points either by measuring or inferring the position of the support points and/or the relative position of the workpiece, establishing starting-point-free regions, establishing end-point-free regions, establishing starting-point-free and end-point-free regions depending on the inferred or measured position of the support points and/or the relative position of the workpiece, establishing a grid of possible starting points and end points, omitting the starting-point-free and end-point-free regions determined in advance, either calculating a torque in a stabilizing and/or tilting direction or calculating a tilt height and/or a tilt depth for each of the points on the grid, setting a priority of points on the grid, transmitting the priority of points to a route planning means of the cutting head, and selecting one of the points on the grid and carrying out the cutting machining.

Abstract: A laser cutting process for cutting at least one workpiece out of a metal sheet while leaving a residual part is provided. The process includes arranging the metal sheet on a support of a laser cutting machine, introducing at least one cutting line for separating the at least one workpiece from the residual part using the laser cutting machine, and introducing at least one separating line into the residual part using the laser cutting machine. In a main region of the separating line, the residual part is cut through. In a connecting region of the separating line, at least one joint remains between mutually adjacent portions of the residual part. The joint has a height that is smaller than a thickness of the metal sheet. The process further includes removing the residual part from the support, and separating the portions of the residual part from one another.

Abstract: A method for determining a minimum width of a microjoint by which, when machining a workpiece, in particular a sheet-like workpiece, a workpiece part remains connected to a remaining workpiece of the workpiece. In the method, the minimum width of the microjoint is determined in dependence on at least one machining parameter which influences a relative position of the workpiece part in relation to the remaining workpiece during the machining of the workpiece. A further method determines an attachment position of such a microjoint and a still further method machines the workpiece.
