Abstract
Sonic energy in a cycloidal or quadrature vibration action pattern is generated in a main vibratory drill assembly by means of a sonic oscillator employing an eccentrically weighted rotor. The sonic energy is transmitted down the drill assembly to the drill bit to cause precession of the bit around the bottom of the drill bore in a cycloidal fashion. The drill assembly is coupled to the drill bit through a spherical ball and socket bearing which enables universal rotation of the bit so that it is not constrained along any particular axis. Thus, the bit is free to tip and to rotate on the sonic drill assembly in an orbiting cycloidal fashion in response to the energy transmitted thereto.
