Study on vibration drilling of fiber reinforced plastics with hybrid variation parameters method

Delamination is recognized as one of the major causes of damage during drilling of fiber reinforced plastics (FRPs), which not only reduces the structural integrity, but also has the potential for long-term performance deterioration. It is difficult to produce precise quality holes with high efficiency by conventional drilling method. In this paper, a new vibration drilling technology is presented using a hybrid variation parameters method, based on the model for predicting critical thrust forces and the model for predicting thrust and torque during vibration drilling of FRPs. From the drilling experiments, it was found that both precise quality holes and high efficiency could be obtained by this new drilling method.
