Abstract

Fiber Laser micromachining technique has a great ability to because of high laser beam intensity, good focusing characteristics with lesser maintenance. In laser micromilling for higher depth, multiple scans of laser beam are  required. In this study, controllable factor like pulse overlap, number of scans  were considered to determine the depth of Ti6Al4V. The central composite designed (CCD) technique based on response surface methodology (RSM) is employed to plan the experiment and to develop mathematical regression model. A significant parameter has been selected based on the analysis of variance (ANOVA). The depth is achieved between 49 and 163 µm. Maximum average surface roughness was measured up to 19.95 µm.
