Publication number: 20240125232Abstract: A cutter head includes a first member, a cutting bit, and a second member. The first member includes a first end and a second end and includes a first mass. The cutting bit is coupled to the first member proximate the second end. The cutting bit includes a cutting edge rotatable about the axis. The second member 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 and the cutting bit to oscillate.Type: ApplicationFiled: July 10, 2023Publication date: April 18, 2024Inventors: Russell P. Smith, Andrew D. Hunter, Peter A. Lugg, Ian B. Schirmer, Geoffrey W. Keech, Christopher Coates, Bradley M. Neilson
