Abstract: Additive manufacturing (AM) has revolutionized modern production by enabling the fabrication of intricate and precise geometries. Despite these advantages, secondary finishing processes like micromilling are often required to meet stringent surface quality and dimensional accuracy demands. This research focuses on evaluating the role of minimum quantity lubrication (MQL) in optimizing tool performance and surface finish during the micromilling of Inconel 690, a nickel‐based superalloy valued for its superior mechanical strength and corrosion resistance. Comparative cutting experiments were conducted under three cooling strategies: dry machining, MQL, and conventional flood cooling. Tool wear and surface integrity were assessed using scanning electron microscopy (SEM) and 3D surface profilometry. Furthermore, a comprehensive sustainability analysis was performed using the Pugh matrix, considering economic, environmental, and technical aspects. Findings reveal that MQL effectively minimizes tool wear and improves surface quality while providing a more sustainable and efficient alternative to traditional flood cooling methods. The Pugh matrix analysis further confirms MQL as the most sustainable option, balancing cost, efficiency, and environmental impact. These findings contribute to the advancement of sustainable machining strategies for AM components, promoting improved performance and cost efficiency in industrial applications.
