METHOD FOR DETERMINING THE EFFECTIVENESS OR CHANGE IN EFFECTIVENESS OF A SLAG REMOVAL, AND ASSOCIATED LASER PROCESSING MACHINE

摘要

The invention relates to a method for determining an effectiveness and/or a change in effectiveness of a slag removal of a laser processing machine (1), comprising the following steps: capturing a current flow noise generated during the slag removal; and determining the current effectiveness and/or the current change in effectiveness of the slag removal by comparing the captured current flow noise with at least one stored reference flow noise.
