🕳️ Tunnel Boring Cutterhead: Disc Cutter Force, Thrust, Torque and Penetration (2D)

Face view of a tunnel boring cutterhead with a magnified disc cutter pressing into rock. Set the head diameter, number of cutters, rock strength, penetration per revolution, speed and cutter load rating, and read the normal and rolling forces, thrust, torque, power, advance rate and specific energy. Four in-page numerical checks. A mechanics companion to the 3D cutterhead assembly.
