Analytical determination of the rational axial load on a cutter crown
Abstract
In the course of experimental drilling, critical values of the axial load were established at which the mechanical penetration rate reaches its maximum values. The obtained axial load values were taken as rational. As a result of the research carried out, a formula suitable for calculating the rational axial load on a cutter bit has been found analytically and verified experimentally.
