Study on the Test of Pulse Laser Processing of Brittle Materials

Abstract:

Texturing processing experiment of SiC and YG8 surface was done by using lamp-pumped YAG-T50 laser marking machine and the depth of groove and the surface roughness was measured by using PS50 measurement which is non-contact. Through experiment, process parameters, such as effective vector step, effective vector step delay, Q frequency, laser current, effecting on the quality of the micro-shape processing were been researched. The experimental results show that, when effective vector step delay or laser current increases, the depth of the helical groove increases;while effective vector step or the Q frequency increases, the depth decreases;the surface roughness value decreases along with increasing of effective vector step delay Q frequency and laser current, increasing when effective vector step increases.
