To solve the delamination, tearing and fiber losing of carbon fiber reinforced plastic (CFRP) hole induced by large cutting force and torque during conventional drilling (CD), the rotary ultrasonic-assisted drilling (RUAD) technology is introduced. Firstly, based on the analysis of the types and forming mechanism of CFRP hole defects in CD and the characteristics of RUAD, the defect suppression mechanism of CFRP hole in RUAD is proposed. Then, the experimental platform including a self-designed contactless energy transfer and a vibration system for RUAD, vertical machining center platform and force measurement system is built. Finally, the cutting force and torque, hole defects and quality of hole wall obtained in both CD and RUAD are compared at the same process parameters, respectively. The experimental results indicate that compared with CD, the cutting force and torque produced in RUAD decrease by 41.46% to 46.32% and 41.61% to 48.94%, respectively. And the delamination, tearing and fiber losing of the CFRP hole are effectively suppressed and the hole quality is greatly improved. The forming mechanism of hole defects in CD and the defect suppression mechanism of CFRP hole in RUAD are verified to be correct by the experimental results. The research in this paper indicates that the RUAD process can be used for machining of CFRP hole with lowdamage.
