In the context of the laser cutting optimization,
this paper presented the application of
combined TM-DRSM approach for optimization
of the CO2 laser cutting of 2 mm thick structural
steel S355J2G3 EN 10025 sheet. To obtain
experimental data for surface roughness, the CO2
laser cutting experiment was planned and
conducted according to the principles of
Taguchi’s experiment design using the L25
orthogonal array.
