To experimentally validate the optimization
results, one needs to perform the experiment
under the optimal cutting conditions (vopt =
6.999 m/min, Popt = 1.496 and popt = 3.349 bar).
Considering the technical limitation of CO2 laser
machine used for adjusting cutting parameter
settings, the confirmation experiment was
carried out at a condition closest to the optimum
condition. The laser cutting parameters settings
in the confirmation experiment with the
corresponding average values of S/N ratio and
Ra are given in Table 7.
