Experimental Study of Cryogenic Milling of AZ91D Mg Alloy-eco Friendly Machining

K Venkata Krishna and K. Nimel Ross


The purpose of this research is to evaluate the surface roughness (SR) received under dry, flood, and the novel cryogenic methods in machining of the magnesium (Mg) alloy. Two groups, the experimental group (cryogenic) and the control group (dry) were picked for the study. The quantity of samples is calculated using the sample calculator. There were 9 samples taken for each group. The Mg alloy is cut in the control group without any lubricant. In the experimental group, the cryogenic technique is applied to the machining which is contrasted against the dry and flood method. Each group’s SR is measured using a SR tester. We examine the impact of the distinctive dry, flood, and cryogenic methods on SR. In comparison to samples acquired from machining, T-independent tests were done using the SPSS statistical tool. According to the experimental data, cryogenic technique has lower surface roughness, with an average of (p < 0.05). Surface finish significantly increases whenever the cryogenic method is used as compared to dry and flood methods, which paves the way for sustainable manufacturing.
