Physical phenomena at destruction of hard rocks by blunting wedge cutter, complete formula of penetration rate and its application
Authors:
Abstract
The problem of the rate of penetration in rotary drilling of hard rocks with a sharpened cutter is reduced to the establishment of the general dependence of penetration H on time t at given parameters of the drilling mode: axial load c0 and the number of revolutions n and to determine the initial rate of penetration v0 ...
