Composite materials are used for many structures because of its high strength-to-weight ratio and easy formation. Secondary machining processes such as drilling and sawing are required to assemble and join composite materials to other structures. When composite materials are machined, machined surface is sometimes rough and it causes delamination of layers and failure of composite material. In this paper, improvement method of machined surface of composite material during drilling is examined. In this method, ultrasonic vibration is used during drilling. First, this method is examined experimentally. Improvement of machined surface is evaluated by surface roughness. It is concluded that machined surface is improved when ultrasonic vibration is used during drilling. Next, experimental results are examined by an analytical method. Cutting force is modeled as equivalent damping force. Condition of improvement of machined surface is proposed.
