Abstract
This study investigates the effectiveness of coconut oil as a lubricant in the machining of 1100 aluminum under minimum quantity lubrication (MQL) conditions, aiming to enhance machining performance by reducing tool wear, improving surface finish, and minimizing energy consumption. Experimental tests, conducted under controlled conditions with varied cutting parameters and lubrication techniques, analyze the influence of coconut oil on machining outcomes. The findings suggest promising implications for coconut oil as a sustainable lubrication solution in metal machining processes. Additionally, the challenges associated with machining aluminum alloys, including tool wear, surface integrity, and chip formation, are addressed through the investigation of Minimum Quantity Lubrication (MQL). The study evaluates the impact of MQL on various aspects of aluminum alloy machining, utilizing a CNC milling machine, aluminum alloy workpiece, and carbide cutting tool. Comparison between MQL and dry machining techniques reveals significant reductions in tool wear, improved surface finish, enhanced chip evacuation, and decreased cutting forces with MQL. Moreover, the implementation of MQL leads to reduced cutting zone temperatures, thereby enhancing tool longevity and machining effectiveness. Overall, Minimum Quantity Lubrication (MQL) demonstrates favorable outcomes for aluminum alloy machining, offering valuable insights for optimizing machining parameters and lubrication methodologies to improve performance in aluminum alloy machining operations.
