摘要：

In this present study, an effort is needed to build a decision-making process based on multiple criteria in laser beam drilling process for enhancing machining process measures of Nickel Inconel 718 alloy. The present study proposed Taguchi-Grey Relation Analysis (TGRA) to obtain optimal process factors for deriving better material removal rate and surface finish with lesser taper angle in the machining process. It is an essential to enhance the laser cutting mechanism for obtaining better surface quality measures. Power [laser] (2 KW), the distance of nozzle (0.7 mm), focal-length (+2 mm) and the gas-pressure (3 bar) were selected as optimal factors with accuracy of 4.2%. Gas pressure has the dominant role on the performance measures in LBM owing to its significance of concentrated energy. The surface topography could be obtained with negligible micro cracks on machined specimen under the proposed optimal process factors. © 2022
