Influence of cutter terminology on the functionality of additive manufactured Inconel 718 alloy

The surface morphological features of a mechanical component play an essential role on its functionality while it is in usage. Further, the occurrence of poor surface morphological features on the Additively Manufactured (AM) alloys leads to invoking an adverse impact on the functional behavior of manufactured components. In this study, the impact of machining circumstances and tool terminology during slot milling operation on the surface morphological features of additively manufactured Inconel 718 alloy have been examined under dry-cutting circumstances, and found that the cutter terminology has invoked a bigger influence on the surface morphological features such as Sa, Ssk, etc. of additively manufactured Inconel 718 alloy trailed by the machining circumstances, owing to its bigger impression on the machining behavior. Moreover, the statistical tool such as ANOVA, the ratio of signal-to-noise study and regression methods are employed to determine the dominant machining factor and tool terminology which helps to achieve better machining behavior which leads to invoke greater surface features.
