Paper Abstract

Laser ablation with a Q-switched diode-pumped Nd:YAG laser was used to produce grooves in H-13 tool steel and 6061 aluminum specimens. The relationships between laser wavelength, power and travel speed and the material removal rate, groove depth and quality were studied. Nondimensional relationships between the process and material variables and groove area and depth were found. The material removal rate was found to be significantly higher for the aluminum material. However, no significant increase in material removal or groove quality was found for the shorter wavelength laser energy. Significant recast was observed in grooves having a depth/width ratio larger than approximately 1 and all grooves had some amount of recast material remaining as a burr at the top edges.
