The goal of this study is to compare the performance of coated and uncoated inserts while minimising surface roughness when turning the innovative AA5052+3%MoS2+9%Si3N4 hybrid aluminium metal matrix composite (HAMMC). The workpiece material taken into consideration for this investigation was unique HAMMC, which used AA5052 as the base alloy with 3 weight percent solid lubricant molybdenum disulfide (MoS2) and 9 weight percent silicon nitride (Si3N4) ceramic as reinforcement. Two cutting inserts—an uncoated insert (control group) and a TiN coated insert—are used throughout the turning process on the cast HAMMC (experimental group). Cutting parameters including feed rate, depth of cut, and cutting speed are held constant. Based on an 80% G-power calculator, 20 samples for each group were taken into consideration. As a result, the uncoated insert's mean value of surface roughness is 2.364 m while the TiN-coated insert's is 1.588 m. The results of an independent sample t-test with a significance value of 0.005 (p0.05) indicate that there is a substantial variance among the groups taken into consideration. Due to less shearing force and friction, it is concluded that turning the HAMMC with a coated insert results in lower surface roughness than machining with an uncoated insert.
