A method for monitoring a laser machining process for machining workpieces includes: for a plurality of machining steps, detecting a measurement signal for at least one measurement variable during a machining step; in a setting phase, defining a limit value for at least one monitoring parameter based on the measurement signals detected during the setting phase; and in a monitoring phase, determining a monitoring parameter value for each machining step based on the measurement signal, comparing the monitoring parameter value with the limit value to identify a faulty machining step, and determining whether a process change condition is met based on the measurement signal of at least one machining step. After a predefined setting time interval or number of machining steps during the setting phase, switching from the setting to monitoring phase, and switching back from the monitoring to setting phase when the process change condition is met.
