Laser-cutting workpiece to be processed arranged in defined initial position, comprises laser beam into the workpiece at predetermined position, and providing the workpiece with cutting gaps starting from the position by relative movement

摘要

The method comprises a laser beam into a workpiece (2) to be processed at a predetermined position, and providing the workpiece with cutting gaps starting from the predetermined position by a relative movement between the workpiece and the laser beam. The workpiece is arranged in a defined initial position. The cutting gap follows a given path curve. A given cutting gap angle is assigned to each point of the path by adjusting an impact angle and focusing the laser beam. The focusing of the laser beam takes place in the form of adjusting the beam rotation diameter of the laser beam. The method comprises a laser beam into a workpiece (2) to be processed at a predetermined position, and providing the workpiece with cutting gaps starting from the predetermined position by a relative movement between the workpiece and the laser beam. The workpiece is arranged in a defined initial position. The cutting gap follows a given path curve. A given cutting gap angle is assigned to each point of the path by adjusting an impact angle and focusing the laser beam. The focusing of the laser beam takes place in the form of adjusting the beam rotation diameter of the laser beam performing a rotation and a wobbling movement. The path curves of the cutting gaps are closed. An independent claim is included for a device for laser-cutting a workpiece to be processed arranged in a defined initial position.
