Embodiment Construction

[0035] figure 1An exemplary sequence of a method for cutting through a solid by means of a high-energy beam is shown. The laser in a laser cutter is particularly suitable as a high-energy beam. In method step S10 , at least one defined contour or at least one piece of information about at least one characteristic of the defined contour is stored in a control unit, which is preferably integrated in the laser cutting machine. However, it is also possible to store several defined profiles. Preferably, the stored defined contour is a curved groove, in particular in the form of an I-shaped groove, a T-shaped groove, a rounded I-shaped groove or a rounded T-shaped groove. In any case, the contour should be followed and the cutting gap produced, even if, for example, after machining a solid, the resulting cutting gap is greater than the one stored in the NC program and originally set to be implemented. In a method step S11 , the control unit searches the NC program for a contour w...

Abstract

The invention relates to a method for detecting and processing predefined contours during severing of a solid body by means of a high-energy beam. To this end, the defined contours are stored in a control unit that controls the severing (S10), and when they occur in an NC program are detected by the control unit (S12). The control unit deactivates the function for avoiding contour breaches (S13),and generates a cutting gap (S14) in accordance with a programmed contour. According to the invention, the high-energy beam travels along the contour with an averaged line movement.

Description

technical field [0001] The invention relates to a method for cutting off solids, wherein a high-energy jet travels along a contour on a surface of the solid facing the high-energy jet and produces a cutting gap there, wherein a control unit for cutting off has a device for detecting the contour The function of damage and the function of avoiding contour damage. Furthermore, the invention relates to a control unit for carrying out such a method. Background technique [0002] Currently, numerically controlled or computer-aided numerically controlled cutting machines are used to manufacture or cut sheet metal. A numerically controlled (NC) unit or a computer-aided numerically controlled (CNC) unit (hereinafter simply referred to as a control unit) is a device for controlling a machine that reads control instructions set as codes on a data carrier and converts them into work process or movement process. The groove to be produced is described as a profile in the NC program or ...
