Effect of Laser Parameters on the Surface Roughness of EN AW 5754

Popis výsledku v původním jazyce

This paper aims on effect of parameters change of fiber laser cleaner MRJ FL C120 on alluminium alloy (EN AW 5754) samples. Adjustable parameters are frequency, pulse time, cleaning area and number of spirals, which fill the cleaning area. These parameters also effects energy density and power density. Experimental plan is made to cover whole range of adjustable parameters. Surface roughness was measured in line with contact device. Two areas were lasered with the same parameters for minimalize effect of oxidation layer and surface roughness was measured several times. Lasered surface was also investigated with electron microscope. It was found from the measured data that by suitable setting of parameters it is possible to achieve roughness from 0.187 to 4.514 µm. The laser trace was visible with an electron microscope. It was found that high frequency causes a smaller depth of the trace.
