Apstrakt:
This study presents experimental results regarding kerf width obtained in CO2 laser cutting of aluminum alloy AlMg3. Laser cutting experiment, conducted according to the full factorial design, where three laser cutting parameters (laser power, assist gas pressure and cutting speed) were varied at three levels, provided a set of experimental data for the development of mathematical model for the prediction of the kerf width. Statistically assessed as adequate, the developed mathematical model was used for the analysis of interaction effects of selected laser cutting parameters on the kerf width. It was observed that assist gas pressure predominantly affects the laser cutting process of aluminum-magnesium alloy considering kerf width.
