Influence Of Process Variables On Machining Characteristics In Turning Of Novel Am Alloy

In this paper, the machinability of a fabricated AM alloy (Mg-7 wt%Al-0.9 wt%Mn) has been examined. The novel AM alloy was subjected to turning using a systemized CNC setup. The input turning variables: feed (f), cutting speed (v), and depth of cut (DOC) were suitably altered to analyze effects on response variables such as cutting force (F-c), cutting temperature (T), and tool life (T-L). Subsequently, the microstructure characterization of the machined surface was done for validating the experimental results. The experimental results established the influence of input parameters on response variables. The cutting force was mostly dominated by DOC, and the cutting temperature was predominantly influenced by cutting speed. The SEM images exhibited the adverse effect of higher values of input parameters on the surface condition. The finest surface was observed at f: 0.1 mm/rev, DOC: 0.5 mm, and v: 115 m/min. Further, the analysis of tool life was done by assessing the flank wear; the measured data showed the significant influence of cutting speed on flank wear. The maximum tool life of 51 min was achieved at the lowest levels of three input parameters.
