METHOD FOR ECCENTRICALLY ORIENTING A LASER CUTTING BEAM IN RELATION TO A JET AXIS AND FOR ANGLE CUTTING, CORRESPONDING LASER MACHINING HEAD AND LASER MACHINING TOOL

摘要

Process for laser beam angle cutting of a workpiece (1) in which an ultrasonic gas cutting stream from a gas cutting nozzle (3) is directed at an oblique (sic) cutting angle to the workpiece surface (1a), the workpiece is moved relative to the laser cutting beam (2) and the oblique cutting angle is perpendicular to the feed direction. During this relative motion a position (P) of the laser cutting beam on the workpiece surface (1) is so set that the laser beam strikes a high pressure region (5) on the workpiece surface formed within the ultrasonic gas cutting stream (4). Independent claims are included for: (1) a laser cutting machine (2) a computer program for setting the laser machining process.
