AbstractThe effects of cutting parameters which are used in CO2 laser machines on surface roughness of AISI 304 quality stainless steel sheet after cutting process is examined in this study. 3 mm AISI 304 quality stainless steel is prepared with the help of a determined geometrical model by cutting. In processing experiments, parameters are divided into two sections as constants and variables. Frequency, Duty, Nozzle, Material, Speed and Lens parameters are kept as constant, Power, Focus, Pressure and Substitute Gas parameters are kept as variable. The experiments were carried out in accordance with the full factorial experiment. The average surface roughness values was measured after cutting experiments and evaluated by ANOVA (Analysis Of Variance) variance analysis. The measured average surface roughness values ranged from 1.261 to 4.156 µm. The parameters of power, pressure and auxiliary gas are affected by surface roughness, Focus distance has not been effective. This study is thought to have an important position to light the way for the companies which take place in production sector.
