Title
(EN) METHOD FOR AUTOMATED CONTROL OF MATERIAL PROCESSING
(FR) PROCÉDÉ DE COMMANDE AUTOMATISÉE DE TRAITEMENT DE MATÉRIAU
Abstract
(EN)
The disclosed invention comprises a method for automated control of material processing processes, wherein the method is controlled by a control unit (12) calculating correction output signals (u) and controlling an energy generator unit (1), an energy delivery unit (3), an energy delivery output measurement (4), at least one material- energy interaction measurement unit (7) for measurement of actual machining results (s), which are fed via a control unit input (13) and sub-units for generating correction output signals (u) in a close loop, which lead to desired machining results, wherein the correction output signals (u) are applied via a control unit output (14) to the energy generator unit (1) and the energy delivery unit (3) by an energy delivery control sub-unit (11) and/or a second energy delivery control sub-unit (15), and the computation of correction output signals (u) is executed by machine learning procedures.
