Abstract:
This paper
researches ultrasonic vibration drilling of carbon fiber
reinforced polymers composites that are hard, brittle, and have
low shear strength between layers. An experiment plan has been
developed to reduce the axial force. Experimental studies have
been done on the influence of process parameters, tool
structures on the drilling axial force. The drilling mechanism
is specially investigated. Thus an effective method is presented
to reduce the drilling axial force. The authors suppose that
ultrasonic vibration drilling is feasible for carbon fiber
reinforced polymers composites.
