【Abstract】 The experimental conclusions of drilling super fine particle reinforced Al matrix composites was presented, induces regularity of drilling force which is influenced by many factors, such as drill parameters. The ratio of longitudinal force to drilling torque is adopted to describe drill property of this material. As for as drilling force is considered, high speed steel bit is enough to drill these material.更多还原
