Optimization with Taguchi Method of Laser Parameters Necessary for Smooth Groove Bottom in ZAMAK 5

Abstract

In this study, groove-shaped cavities were created with Nd: YAG laser on ZAMAK 5 plates, which have been used frequently in the industry for many years. The necessary laser parameters have been optimized so that the created cavity floor has a homogeneous depth. The effects of the beam diameter, laser energy, shielding gas type, and duration of the single pulse of Nd: YAG laser used on the roughness in the cavity were tried to be optimized. It was used for optimization. According to the ANOVA table, the optimum parameters are “580µm, 7J, Nitrogen, 7 ms for spot diameter of spot, the energy of single spot, type of ambient gas and a spot of single pulse respectively. The Taguchi method also indicates how effective the laser parameters used are in obtaining the desired surface. It has been concluded that the ambient gas used is the most important parameter in this study. The effect rate was obtained as 74.90 %. Then, laser spot diameter and pulse energy and lastly pulse duration are fewer effective parameters respectively.
