FEM modeling and simulation of kerf formation in the nanosecond pulsed laser engraving processFEM modeling and simulation of kerf formation in the nanosecond pulsed laser engraving process Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2022-09-262021enThis research is co-financed by Greece and the European Union (European Social Fund—ESF) through the Operational Programme «Human Resources Development, Education and Lifelong Learning» in the context of the project “Strengthening Human Resources Research Potential via Doctorate Research — 2nd Cycle” (MIS-5000432), implemented by the State Scholarships Foundation (IKY).In the present study, a finite element method (FEM) simulation model is developed for nanosecond pulsed laser engraving process. The model’s novelty lies in the fact that it predicts the actual dimensions of the engraved geometry emphasizing the dimensional deviation due to the defects from kerf formation such as the sloped side walls instead of the intended vertical ones. Simulations were performed and the values of kerf taper angle, top kerf width and bottom kerf width were compared with the corresponding ones from experimental tests made using a LASERTEC 40 laser engraving machine and also were used for process optimization.http://creativecommons.org/licenses/by/4.0/CIRP Journal of Manufacturing Science and Technology35236-249 Nikolidakis Evangelos Νικολιδακης Ευαγγελος Antoniadis Aristomenis Αντωνιαδης Αριστομενης Elsevier Laser engraving process Laser ablation FEM Modeling Simulation Kerf formation
