... of the rock due to shear dilatancy can only partly explain the reduced efficiencies and the high MSE required to cut rock under pressure ( Judzis et al. 2007 ; Black et al. 2008 ). To analyze the rock-drilling process from an energy point of view, Simons (1962) and Teale (1964) used the concept...
