Sažetak
Studies on the surface macrostructure and microstructure and the subsurface of the cut, indicate that by measuring various roughness parameters, the laser cutting process can be optimized very successfully. Different energy inputs and various modes of laser beam operation allowed us to ascertain that the major influence on cut quality was exerted by beam power and cutting speed, which determine the amount of energy transferred to the cutting front. The results of our studies conducted so far, and the experience gained in assessment of the laser cut quality, confirm that knowledge of the lower and upper cutting speeds is necessary for determination of the optimum parameters of laser cutting. As a result of poor circular polarization the cut quality depends on the cutting direction.
