Keywords:
laser machining, shaped surfaces, KF301 5LN, RSM, surface roughness Ra, ANOVA, CAD/CAM integration, Taguchi L27, software optimisation.Abstract
Purpose: To develop a mathematical model and software for optimising the technological parameters of finish laser machining of shaped surfaces on the KF301 5LN multi-axis laser machine tool, and to validate the approach experimentally.
Methods: Response Surface Methodology (RSM) combined with Taguchi L27 orthogonal array (81 experiments across R6M5, VK8, and VT6 materials); ANOVA for factor significance; Nelder-Mead optimisation; CMM and profilometer metrology.
Key results: R² = 0.973 empirical model; surface roughness reduced by 88–93% (Ra = 0.09–0.18 μm); geometric error ±0.002–0.004 mm; HAZ depth 3–12 μm; annual cost reduction ~32%.
