VIBRATORY MILLING MACHINE HAVING LINEAR RECIPROCATING MOTION

摘要

A continuous mining method includes operating a vibratory milling machine
having
a milling head, a base, and a milling tool to oscillate the milling head in a
substantially linear
reciprocating fashion relative to the base to move the milling tool along a
milling axis; and
advancing the vibratory milling machine in a work piece in a cutting direction
and wherein
milling axis is oriented at an attack angle relative to the cutting direction,
the attack angle
being between about 0 and about 40 degrees.
