Aluminum metal matrix composites are widely used in today's technology due to their advanced properties. In this study, machining of nano B4C particle reinforced Al2024 matrix metal composites produced by powder metallurgy method is discussed. Al2024 and 0, 1, 2, 3 and 4 wt% nano-sized B4C powders were mixed by mechanical alloying. The mixed composite powders were compacted in the hot press device at a certain temperature and time. Brinell hardness tests were applied to nanocomposites. SEM and EDS analyzes were performed on the prepared samples before machining. The samples were machined with CNC method in certain parameters. The hardness measurements of the machined samples were made, and the material removal rates, and surface roughness were measured. The machined surfaces were examined by SEM analysis. In the light of the data obtained, the surface hardness increased with the increase of B4C reinforcement. However, with the increase of reinforcement, the surface roughness of nanocomposites increased, while the material removal rates decreased.
