Abstract

Extreme difficulty is encountered while micro-drilling AISI316L. Such an operation could benefit from the use of nonstandard machining techniques. The most effective method for micro-drilling is the use of a laser beam. Laser drilling may provide subpar results due to the beam's high heat energy and divergent convergence properties. In this study, we employ a Nd:YAG laser beam and explore how changing the laser's input parameters affects the outcomes. In order to reduce the total number of tests, we get maximum data for each trial. As a result, a rotating composite center has been included into the design. Analysing inputs and outputs using analysis of variance helps isolate influential factors. This article demonstrates that the top-hole circularity is significantly influenced by both current and gas pressure. The bottom side circularity is significantly affected by the current and the pulse frequency. The hole taper is significantly influenced by the cutting current and cutting speed.
