Abstract
The invention relates to a method for collision avoidance of a laser machining head (102) in a machining space (106) of a laser machining tool (100), having the steps of: —Monitoring a workpiece (112) in the machining space (106) with at least one optical sensor; —Capturing images of the workpiece (112); —Detecting a change in an image of the workpiece (112); —Recognising whether the change comprises an object standing upright relative to the workpiece (112); —Checking for a collision between the upright object and the laser machining head (102) based on a predetermined cutting plan and/or the current position (1016) of the laser machining head; —Controlling the drives for moving the laser machining head (102) for collision avoidance in case of recognised risk of collision.
