Abstract

Laser micromachining is a powerful process of creating new surfaces, structures, cavities and also complex electro-mechanical devices with very small dimensions by laser radiation. This process highly depends on choosing proper parameters and their settings. An experimental investigation of laser micromachining with low-power, diode-pumped Nd:YAG laser is presented in the paper. Material used in the experiment was austenitic, Cr-Ni stainless steel type X5CrNi18-10 (1 mm thin metal sheet). The experiment was planned by Taguchi method and the created cavities were evaluated by conventional optical and also confocal microscopy in order to state the surface roughness and the volume of removed material. It was demonstrated practically that low-power laser is able to remove material from workpiece, and it was confirmed that this process is crucially sensitive to input parameter settings.
