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