    摘要: A cutter head 22 includes a first member 90, a cutting bit 86, and a second member 94. The first member 90 includes a first end and a second end and includes a first mass. The cutting bit 86 is coupled to the first member 90 proximate the second end. The cutting bit 86 includes a cutting edge rotatable about the axis. The second member 94 is rotatable about the axis and includes a second mass eccentrically positioned with respect to the axis. Rotation of the second mass causes the first member 90 and the cutting bit 86 to oscillate.
