Mill-grinding machining for particle-reinforced aluminum matrix composites

With the excellent mechanical properties, particle-reinforced aluminum matrix composites have gained widely application in aeronautics and astronautics industries. Due to the high brittleness, workpiece breakage often occurs during the cutting processes, as the results, the machining quality is hard to be satisfied. In the paper, a mill-grinding method for machining particle-reinforced aluminum matrix composites is proposed and studies on machining effect of the method and tool wear are carried out based on experiments. The results indicate that the mill-grinding can avoid workpiece breakage in the machining process and it is an effective method for machining particle-reinforced aluminum matrix composites.
