Laser cutting is one of the most important processing techniques that does not require contact
with the surface of the material, used in many production stages, and applicable to various steels. How the
variation of laser parameters affects the material's surface properties is an important area of research. In
this study, the effect of fiber laser parameters on the surface properties of ST52 steel subjected to the cutting
process was investigated. In the study, three different laser parameters, each at three levels, namely laser
cutting speed, laser power and gas pressure, were determined as input parameters. The output parameters
used in the analysis are surface hardness, roughness and heat affected zone depth. ANOVA tables were
created for each output parameter using the Minitab program and the effects of the laser parameters were
determined. The analysis results showed that the laser cutting speed is the parameter that most affects the
surface roughness, hardness and depth of the heat-affected zone, with statistical significance. Additionally,
laser power has a statistically significant effect only on the heat affected zone, and the effects found for
hardness and roughness are not statistically significant. The gas pressure showed a significant effect only
on the surface roughness. The study highlights the importance of precise control of laser parameters to
improve surface quality and processing efficiency in industrial applications.
