Embodiment Construction

[0037] figure 1 The laser cutting machine 1 shown three-dimensionally as a platform machine includes, for example, a CO 2 A laser beam generator 2 of a laser, a diode laser or a solid-state laser, the laser cutting machine also includes a laser processing head 3 and a workpiece support 4 that can move in the X and Y directions. A laser beam 5 is generated in the laser beam generator 2 , which is guided from the laser beam generator 2 to the laser processing head 3 by means of an optical cable (not shown) or a deflection mirror (not shown). The laser beam 5 is directed by means of a focusing lens arranged in the laser processing head 3 onto a workpiece 6 (for example a sheet metal) located on the workpiece support 4 . Furthermore, the laser cutting machine 1 is supplied with process gases 7 , such as oxygen and nitrogen. A process gas 7 is fed to a process gas nozzle 8 of the laser machining head 3 , from which process gas emerges together with the laser beam 5 . Laser cutti...

Abstract

The disclosed method for machining flat workpieces (6), in particular metal sheets, or three-dimensional workpieces (6') on a machining unit (1), especially a machine tool or laser cutting machine, involves the following steps: a) having an image capturing device (12) for capturing two-dimensional images capture a live image (14) of a workpiece (6; 6') to be machined; b) displaying at least one upcoming workpiece machining process (101, 102, 103) in the live image (14) of the workpiece (6; 6') using a predetermined forward transformation (T; T') of the workpiece machining process (101, 102, 103) from the three-dimensional coordinate system (11) of the machining unit to the two-dimensional coordinate system (15) of the live image; c) manually adjusting the position of the upcoming workpiece machining process (101, 102, 103) in the live image (14) of the workpiece (6; 6'); and d) carrying out the workpiece machining process (101, 102, 103) on the workpiece (6; 6') using a predetermined inverse transformation (T-1; T'-1) of the positionally adjusted workpiece machining process (101, 102, 103) from the two-dimensional coordinate system (15) of the live image to the three-dimensional coordinate system (11) of the machining unit.

Description

technical field [0001] The invention relates to a method for processing flat workpieces, in particular sheet metal or three-dimensional workpieces, on a processing machine, in particular a power tool or a laser cutting machine, as well as a suitable processing machine and a suitable processing machine for carrying out the method. A corresponding computer program product. Background technique [0002] The manual or subsequent positioning (repositioning) of the workpiece machining process to be carried out is in many cases time-consuming, imprecise and error-prone. First, the component dimensions must be determined, then the raw material must be measured manually, and finally the starting point must be determined, for example by means of a laser diode. Since this information is often insufficient, a dry run is often first carried out in order to avoid incorrect production or damage to the processing machine. [0003] It is known from JP 11-320143 to scan the sheet metal to b...
