ABSTRACT:
A method and apparatus is provided for reducing optical chatter for use with a machine that is adapted to perform an operation on a surface of a workpiece by bringing a rotating roller into contact with the surface as the workpiece is advanced past the roller. The roller of the machine has a central axis and is powered to rotate about the central axis. The apparatus comprises an oscillation inducing device that is operably coupled to the roller for inducing an axial oscillation in the roller. The frequency of the induced oscillation of the roller is substantially greater than the frequency of rotation of the roller. The method for reducing optical chatter comprises the step of imparting axial oscillations to the roller during rotation of the roller, the imparted oscillations being of substantially greater frequency than the frequency of rotation of the roller.
