Users can carry out customized adaptations at any time using the simulation created by “TiltPrevention”: modify the nesting of parts, reposition the insertion and end points of the laser, and add micro joints where required. Regardless of the users’ level of experience, “TiltPrevention” supports them with an ideal cutting strategy that can be automatically incorporated into the cutting plan. Cutting in such a manner that the cutting head never travels over parts that have already been cut out. This creates an ideal cutting sequence for all parts on the cutting plan. This reduces the abortion of cutting processes and downtime. The intelligent function enables users to create cutting sequences that minimize the risk of protruding parts.
In addition, the function proposes the best possible route for the cutting head over the metal sheet. With the TiltPrevention assistant function, Bystronic is increasing process reliability in the field of laser cutting. Subsequently, “TiltPrevention” recommends insertion and end points of the laser so that tilting of the parts after cutting is prevented to the greatest possible extent. Right: Laser cutting without “TiltPrevention” with piercings in critical areas (red) and risky paths of the laser. Left: Simulation of the optimized cutting sequences using “TiltPrevention”. To achieve this, “TiltPrevention” takes into account a wide range of parameters: What is the density of the material that is being cut? What is the geometry and weight of the parts that are to be cut? How high is the pressure of the gas that flows out of the cutting head during laser cutting and exerts pressure on the parts? How are the parts positioned on the cutting grate? Are there enough contact points? How does it work? An algorithm calculates the mechanical behavior of the parts while they are being cut out of the sheet. This largely eliminates the need for micro joints. In future, BySoft 7 will use this intelligent assistant function to compile cutting plans in such a manner that parts cannot tilt during the cutting process. With “TiltPrevention” Bystronic has now developed a new solution. Algorithm generates the ideal cutting sequence Another disadvantage: The automated removal of the finished parts is impeded because the micro joints make it difficult to remove the parts from the residual sheet. One disadvantage of this solution is: The cut parts require reworking in order to remove the traces of the micro joints. In this way, parts remain fixed to the surrounding sheet after cutting.

The software positions small connections between the contour of the part that is to be cut and the residual grid in the cutting plan.
Until now, micro joints have been a time-intensive method of preventing cut-out parts from tilting. Right: Tilted parts after laser cutting without “TiltPrevention”. Left: Perfect cutting result thanks to “TiltPrevention”.
