The rock is then slowly displaced by 10mm. The abrasiveness of the rock is obtained by measuring the resulting wear flat on the steel cone. The unit of abrasiveness is defined as a wear flat of 0.1mm diameter.
WebAbstract. This paper presents a complete model of the drilling response of drag bits (or PDC bits as they are often referred to), i.e. a set of relations between the weight-on-bit W, the torque-on-bit T, the rate of penetration V, and the angular velocity Ω. This work complements an earlier paper [Detournay E, Defourny P. The International Journal of Rock Mechanics and Mining Sciences is a peer-reviewed scientific journal published by Elsevier.
