Optimizing Machining Performance of Heat-Treatable Aluminum Alloys Through MQL Condition Parameter Turning in High-Speed Machining

The addition of zinc to aluminum during the manufacturing of aluminum alloys may result in the production of alloys with the highest potential strength. The addition of zinc increases the tensile strength of the material and permits precipitation hardening. Adopting the technique of "minimal quantity lubrication" (MQL) when cutting metal improves machinability and ensures the sustainability of the operation. Because micro-milling does not involve bulk heating, it is necessary for the cutting fluid to be deposited on the tribologically active chip-tool-workpiece region for improved lubrication. Only then can ideal micro-milling outcomes be achieved. Even though there are few materials that can prevent oil droplets from adhering to a tool, they do exist. The cost of machining could increase if there is an abundance of coolant, which also poses a threat to the local ecosystem. In order to eliminate the problems produced by the use of coolant, it is necessary to employ alternate strategies. This is the direct result of what has occurred. In this study, the impact of cutting speed, feed, and lubrication conditions (dry, palmolein oil, and palmolein oil containing 0.2% TiO2) on surface roughness, tool wear, and chip morphology was systematically assessed during the turning of zinc-aluminum under minimal quantity lubrication (MQL).This was accomplished by utilizing the MQL method. The minimum amount of lubricant feasible was used for this (MQL). During the execution of the experiments, the L18 orthogonal array was utilized well. According to the research, copper nanofluids containing MQL are a potential alternative to dry and oil machining. Utilizing the response surface methodology allowed for the creation of ideal values and mathematical models. This allowed for increased study precision. Using copper nanofluids throughout the milling process influenced by 40% reduction in Ra and a 66% reduction in tool wear. When the machining conditions were enhanced, both the Ra and tool wear decreased. This was a result of the optimized machining conditions.
