Abstract

LASER stands for Light Amplification by Stimulated Emission of Radiation. Drilling is one of the most important and successful applications of industrial lasers. Laser drilling of metals is used to produce tiny orifices in the workpiece by removing material to create through holes. However in this study, the focus was on the high performance laser drilling by removing a certain amount of workpiece by conducting trepanning process on stainless steel. In this laser drilling process, the quality of drilled holes was evaluated. A thorough study of the process variables on the quality of the holes produced was performed. In present study, the laser parametric effects and the machining characteristic of surface roughness, Ra on the hole quality after the drilling process run are examined. A statistical approach, referred to as factorial design, given a value of significant level, a= 0.05 is used to test the parameters combinations that affect the hole quality and surface characteristic. For this experimental study, a two level full factorial design were used to examine the influence of parameters combinations on hole quality. The surface roughness is evaluated by measuring the value of Ra on top and bottom side of surface for each holes produced using combination variables of frequency, speed, and pressure. ANOVA result was generated by Minitab vl4 using these measurements data and some graphs were plotted in order to find the main effects which are significant.
