MethodPredictive Modelling and Optimization

ProcedureThe study employed a Box-Behnken design for experimental planning. Various laser cutting parameters (nitrogen pressure, pulse energy, cutting speed, pulse width) were systematically varied. Metaheuristic algorithms (Giant Trevally Optimizer - GTO, and Zebra Optimization Algorithm - ZOA) were used to model the relationship between these parameters and kerf deviation. An ANOVA was performed to identify the most influential parameters. The algorithms were compared for their predictive accuracy and computational efficiency, with the optimal parameters validated through confirmation tests and SEM analysis of surface morphology.
