LASER SYSTEMS AND METHODS FOR AOD ROUT PROCESSING

摘要

Laser systems and methods improve the processing velocity of the routs or other features to avoid exceeding the laser system's dynamic limits. A laser processing system divides laser processing commands corresponding to a plurality of features to be processed on or in the workpiece into process segments. Laser processing parameters and beam trajectories are simulated to determine a maximum processing velocity for each of the process segments. The laser processing system selects one or more of the maximum processing velocities for processing the plurality of features on or within the workpiece. A slowest processing velocity of the maximum processing velocities may be used to process each of the plurality of features. Alternatively, each continuous rout sequence may be processed using a different processing velocity. In other embodiments, each process segment is processed using its corresponding maximum processing velocity.
