METHOD FOR ECCENTRICALLY ORIENTING A LASER CUTTING BEAM IN RELATION TO A NOZZLE AXIS AND FOR CUTTING AT AN ANGLE; CORRESPONDING LASER MACHINING HEAD AND LASER MACHINING TOOL

摘要

The invention relates to a method for the laser beam cutting at an angle of a workpiece (1). According to said method, a supersonic cutting gas stream (4) emerging from a cutting gas nozzle (3) is oriented at an oblique cutting angle (a) in relation to the workpiece surface (1a), the workpiece (1) and the laser cutting beam (2) being displaced in relation to each other during laser beam cutting at an angle. The oblique cutting angle (a) extends perpendicular to the direction of advance (Y). During the relative movement, the position (P) of the laser cutting beam (2) on the surface of the workpiece (1a) is adjusted such that the laser cutting beam (2) is incident on the surface of the workpiece (1a) in a high pressure area (5) formed within the supersonic cutting gas stream (4). The invention also relates to a laser machining tool for carrying out said method.
