A laser machining method includes defining at least one threshold value S0 with respect to a light-intensity-dependent first process variable F in at least one working range KAB or at a working point KAP, detecting a light-intensity-independent second process variable K during operation of a laser machine tool in the at least one working range KAB or at the working point KAP, determining a change in the first process variable F in the at least one working range KAB or at the working point KAP when process conditions change, and changing the at least one threshold value S0 to a second threshold value S0R according to the change of the first process variable F from a first value F0 to a second value F0R.

100.
COMPUTER-IMPLEMENTED METHOD FOR REDUCING ERROR LOGFILES OF A SYSTEM
The invention relates to a computer-implemented method (100) for reducing error logfiles (10) of at least one system (1), and to an associated computer program product (8), a reducing system (5) and a system environment (200) comprising the reducing system (5) and at least one system (1).
