Sustainable Roller Burnishing: Effects on Surface Roughness and Power Consumption in Additively Manufactured AlSi10Mg Alloy

In this study, dry, minimum quantity lubrication (MQL) using vegetable-based oil and multi-walled carbon nanotube-reinforced nanofluid-assisted MQL (N-MQL) burnishing conditions and various burnishing speed and depth of burnishing values were used in the sustainable roller burnishing of additively manufactured AlSi10Mg alloy which is widely used in the aviation and automotive industries due to its superior mechanical properties, and burnishing performance was investigated in terms of surface roughness and power consumption. Then, experimental results were evaluated statistically using Taguchi and variance analysis. N-MQL with a burnishing speed of 10 m/min was shown to be the optimum burnishing condition for both surface roughness and power consumption. The optimum burnishing depth was 0.02 mm for power usage and 0.06 mm for surface roughness.
