In the developing technological world, energy consumption is increasing day by day. Reducing energy consumption on a sectoral basis is very important for sustainable resource use and the improvement of environmental health. The manufacturing sector is one of the sectors where energy consumption is intense. Therefore, even a small improvement in the energy consumption in the machining sector will significantly affect the overall energy consumption, costs, and environmental performance of production systems. Since hybrid aluminum metal matrix composites (AMMC) are difficult to process due to their complex microstructure, energy consumption values during processing are high. For this reason, it is important to determine the most appropriate values by examining the cutting parameters and cooling lubrication conditions during processing to reduce energy consumption. In this article, Al-Gr reinforced hybrid composites containing different proportions of WC and Al2O3 reinforcements were produced. The focus is on the energy consumption when milling these composites under different cooling/lubrication conditions and different machinability parameters such as the dry, minimum amount of lubrication (MQL), and cryogenic-LN2. Taguchi statistical analysis was also used in the experiments. As a result, it was determined that the most effective parameter on the energy consumption values among the control parameters was the feed rate, with a contribution rate of 75.37%. In addition, for minimum energy consumption values, it was observed that the best cutting speed was 150 m/min, the best feed rate was 0.300 mm/rev, and the best cooling/lubrication medium was cryo-LN2 cooling medium.
