METHOD FOR CLASSIFYING A LASER PROCESS AND A LASER MATERIAL PROCESSING HEAD USING THE SAME

摘要

The present invention relates to a method for classifying a laser process of a workpiece by means of a laser material processing head, comprising the steps of recording acoustic data caused by the laser process of the workpiece, transforming the acoustic data into a frequency domain by means of a wavelet decomposition or a windowed fourier transform to generate acoustic frequency features and classifying the acoustic frequency features on the basis of learned acoustic frequency features.
