Digitalization of hydraulic rotary drilling process for Nature
The full hydraulic rotary drilling process consists of many roundtrips in time sequence due to the fact that the soil and rock core sample in the cylindrical tube sampler above the drill bit hasThe rock grinding, one of the purposes of the underwater construction robot, is done by the rotation torque of the rock grinding machine. The rotation torque of the rock grinding machine is proportional to the force that the robot arm applies to the rock grinding machine. If the robot arm applies excessive force the rock grinding machine halts. In contrast, Active Control for Rock Grinding Works of an Underwater

(PDF) Drillability Assessments in Hard Rock ResearchGate
Several methodologies are available to assess drillability (i.e. rock strength, rock surface hardness, rock brittleness, rock abrasivity or rock petrography). This paper includes a review of theRotary drilling is mostly used to drill big holes in large quarries, open pit mines, petroleum extraction, and other fields. Fig. 7.6 shows a diagram of a rotary drilling system. There are two groups of big rotary drilling: (1) rotary crushing by high-point loading to the rock from three cones, as shown in Fig. 7.7 a, and (2) rotary cutting by shear force from drag bits, Rotary Drilling an overview ScienceDirect Topics
