Abstract

The invention relates to a method for preventing safety cell penetration by a laser tool (7), which laser tool (7) is manipulated by a serial manipulator (2) and enclosed by a safety cell (9, 10), which method comprises the steps of: reading the orientation of each joint (3-6) of the serial manipulator (2), calculating the position and orientation of the laser tool (7) using the read orientations of the joints (3-6) and the geometry of the serial manipulator (2), calculating the intersection point of the laser beam (14) axis of the laser tool (7) with a wall of the safety cell (9, 10),calculating the heat input of the laser beam (14) at the intersection point (15), shutting down the laser beam (14) of the laser tool (7) when the calculated heat input rises above a preset threshold. The invention relates also to a combination of a serial manipulator (2), a laser tool (7) a CNC controller (11), a safety cell 89, 10) and a prevention device.(16).
