As a key structural material for rockets, aircraft, spacecraft, and space stations, aerospace aluminum alloy has high requirements for machining quality. However, dry machining of this material leads to poor surface integrity, while minimal quantity lubrication (MQL) has insufficient heat transfer capacity, which has become a bottleneck restricting its lubrication and heat dissipation during machining. Although traditional milling force models based on empirical methods and finite element simulations exist, they are not sufficient to guide industrial manufacturing. In contrast, nanofluids have excellent thermal conductivity and tribological properties, and nanofluid minimal quantity lubrication (NMQL) is expected to solve the above problems, but the matching mechanical model for it is still less studied.Mechanical Behavior and Semi-empirical Force Model of Aerospace Aluminum Alloy Milling Using Nano Biological Lubricant
