Abstract

The invention discloses a laser cutting system (2) for laser flame cutting of a workpiece (1), comprising: a laser cutting head (21), the optical device (211) is used for carrying out optical adjustment on a laser beam (3) irradiating a workpiece (1) to be cut, the cutting nozzle (212) is used for spraying cutting gas to a cutting area, and the adjusting device (213) is used for adjusting a focus (31) of the laser beam (3) by adjusting the optical device (211); and a control unit (22) at least for controlling the adjusting device (213) such that the focal point (31) of the laser beam (3) lies above the workpiece (1) to be cut when the cutting nozzle (212) cuts the workpiece (1) to be cut adjacent to the surface of the workpiece (1) to be cut. A method for laser flame cutting a workpiece (1) is also disclosed. According to some embodiments of the present invention, thick metal sheets can be well cut.

Description

technical field [0001] The invention relates to a laser cutting system for laser flame cutting workpieces, a method for laser flame cutting workpieces, a corresponding laser cutting machine and a corresponding computer-readable program carrier. Background technique [0002] Laser cutting is widely used due to its advantages of high speed, narrow slit, small heat-affected zone, and good verticality of the slit edge, especially for cutting sheets. [0003] The cut formed by laser cutting directly reflects the cutting quality, and even determines whether the cut product meets the predetermined requirements. Especially for thick workpieces, the quality of the kerf edges is usually relatively poor, and special grinding processes are often required to meet the requirements. [0004] The quality of the incision edge is affected by many factors. For example, it is not only related to the characteristics of the laser beam itself, but also related to the cutting gas, the relative re...
