Abstract

Methods for configuring laser machining machines (1) include control (2), whereby different types laser machining processes (A, B, C, D) can be executed using the laser machine (1), these processes being respectively controlled by the control apparatus (2) using process parameters. The processes of different types are categorized in a classification (20), in which a respective set of process parameters (21A-24A; 21B-24B; 21C-24C; 22D-24D), that are used during the execution of the respective process (A, B, C, D), is assigned to each process. During a determination and/or changing of a first process parameter (21A-24A) of a first process (A), a process parameter (S1-S6; 21B-24B; 21C-24C; 22D-24D) of a different process (B, C, D) that is contained within classification (20), is automatically determined and/or changed according to a stored rule, as a function of the first process parameter.
