Abstract: The present invention relates, in one aspect, to a method for process monitoring of a laser machining process for estimating a machining quality, having the following steps, which are carried out in real time during the machining process: —providing (S2) at least one captured first signal sequence with a first feature from the machining zone; —providing (S3) at least one captured second signal sequence with a second feature from the machining zone; —accessing (S4) a trained neural network with at least the recorded first and second signal sequence in order to calculate (S5) a result for estimating the machining quality.
