USE OF PREDICTIVE PULSE TRIGGERING TO IMPROVE ACCURACY IN LINK PROCESSING

摘要

PROBLEM TO BE SOLVED: To prevent a reduction in capacity of triggering generation of a laser pulse at a desired target as a speed of a laser beam axis is increased, in a link-processing system.SOLUTION: A predictive pulse triggering (PPT) method enables precise triggering of a laser beam 100 in the link-processing system. The PPT method entails triggering the laser beam based on estimated relative motion parameters of the target 106 and the laser beam axis 108. The PPT method allows for a six-fold improvement in laser positioning accuracy over the conventional, entirely measurement-based method.
