摘要：In this study the relation between laser beam machining parameters and machined surface quality, applying nanosecond pulsed ytterbium fibre laser (wavelenght 1064 nm, maximal average output power 100 W) and aluminium bronze (AMPCO 25®) as working material, is experimentally studied. The laser micromilling was performed via the cross hatching milling strategy. The influence of the laser pulse intensity, scanning speed and laser track distance on the machined surface morphology formation and surface roughness parameters was evaluated using ANOVA (Analysis of Variance). Finally, the machining quality was evaluated by means of SEM micrographs. The results show that the laser pulse intensity played the most significant role on the final surface morphology formation. It was also documented only negligible influence of the laser track distance on the final surface roughness.
