The drilling process is currently applied for bolt or rivet assembly of composite structures. As for metallic structures, the twist drill is the most commonly used cutter. ...In this paper, an analytical model to calculate the critical thrust force in drilling composite materials is developed. This model relates the drilling critical thrust force to the delamination conditions (opening of cracks).
