Magnesium based metal matrix composites (MMCs) can be employed in various areas such as automobile and aerospace due to its weight saving potential, high specific mechanical properties and excellent damping capacity. Recently, improved strength and ductility have been observed due to the incorporation of nano-scale reinforcements into magnesium. This paper presents the experimental results on the machinability of Mg based metal matrix composites with nano-sized particles (Mg/BN MMCs & Mg/ZnO MMCs) produced by liquid-state processing using micro-milling process. The effect of reinforcement materials and volume fraction, as well as the varying cutting parameters such as feed per tooth, spindle speed and depth of cut on the cutting force and surface characteristic were studied. Additionally, since the refinement of grain size was recognised as one of the main reason that cause strengthening, the effect of grain size on machining performance was investigated in order to reveal the cutting mechanism.
