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 present invention relates to a workpiece (1) on how to tilt the laser beam cutting, gas cutting nozzle ( cutting supersonic gas flow 4 discharged from the 3) and oriented in an oblique cutting angle ( ) to the workpiece surface (1a), the laser beam inclined to each other the workpiece 1 and the laser cutting beam (2) during the cutting operation but substituting the relative movement, the oblique cutting angle ( ) for the laser beam is directed to a method of cutting the slope is to extend perpendicular to the transport direction (Y). A position (P) of the laser cutting beam (2) on the workpiece surface (1a) during the relative movement, the laser cutting beam (2) to the workpiece surface in the high-pressure region (5) formed in the supersonic cutting gas flow (4) (1a) Adjust to blow. The invention also relates to a laser processing machine for performing such a method. ;
