      <abstract xml:lang="ru">
        <p>В процессе опытного бурения установлены критические значения осевой нагрузки, при которых механическая скорость принимает максимальные значения. Полученные значения осевых нагрузок приняты за рациональные. В результате проведенных исследований найдена аналитически и проверена экспериментально формула, пригодная для расчетов рациональной осевой нагрузки на резцовую коронку.</p>

        <p>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.</p>
