Embodiment Construction

[0030] figure 1 An exemplary structure of a machine 1 for laser machining, more precisely laser cutting, of a plate-shaped workpiece 2 shown in dashed lines is shown with the aid of a laser beam 3 . For cutting the workpiece 2 , instead of the laser beam 3 , other types of thermal processing beams such as plasma torches or water jets can also be used. The workpiece 2 is supported during machining on two workpiece support surfaces 4, 5 which, in the example shown, form the upper sides of the two workpiece tables and define a support plane E (XYZ coordinate system X-Y plane). The workpiece support surfaces 4, 5 can be formed by table surfaces or by needle-shaped support elements (a plurality of needles), support belts, brushes, rollers, balls, air cushions or the like.

[0031]The workpiece 2 can be moved in a controlled manner on the workpiece support surfaces 4, 5 in a first direction of movement X (in the following: X direction) by means of a conventional movement and holdi...

Abstract

The invention relates to a method for predicting the tipping tendency of a workpiece part (18) cut out from a remaining workpiece and supported on one or more supports during separate processing by means of a processing machine (1, 100), said The method has the following method steps: a. Determine one or more possible tilting edges (71, 81a, 81b) around which the cut-out workpiece part (18) can tilt; b. . For at least one possible tipping edge (71, 81a, 81b), in particular for each possible tipping edge (71, 81a, 81b): determine in different states of the processing machine (1, 100) Act on the tipping moment (M1 to M4) on the workpiece part (18); c. According to the tipping moment (M1 to M4) obtained: whether the workpiece part (18) will be tilted around The edges (71, 81a, 81b) tip over.

Description

technical field [0001] The invention relates to a method for predicting the tendency to tip over of workpiece parts cut out of a remaining workpiece and supported on one or more supports during separate machining by means of a machining machine. Furthermore, the invention relates to a processing machine for separate processing of plate-shaped workpieces by means of a processing beam, which processing machine has a processing head for directing the processing beam, in particular a laser beam, onto the plate-shaped workpiece. Background technique [0002] When cutting workpiece parts on a laser cutting device, such as a flatbed cutting device, a combined laser stamping device or a hybrid device, the cut workpiece can tip over due to its weight and / or due to the cutting gas pressure. This may cause problems in the subsequent process. When cutting other workpiece parts, collisions may occur or workpiece parts can no longer be automatically removed from the machine. [0003] DE...
