Claim 0:
1. A method comprising the steps of:
rotating about an axis in a direction a brush having a multiplicity of radially projecting bristles with tips engaging a surface of a workpiece to be treated;
positioning a stop nonrotatable with the rotating brush in engagement with the bristles radially inward of the stop so as to rearwardly deflect the bristles prior to contact with the workpiece and thereby store kinetic energy in the bristles, whereby as the bristles pass the stop the kinetic energy is released and the bristles spring elastically forward, percussively strike the workpiece surface, and modify a roughness of the surface;
determining roughness of the workpiece surface of the workpiece immediately downstream in the direction from where the bristles strike the surface;
positioning the stop radially relative to the axis or the brush relative to the workpiece at a spacing in accordance with the determined roughness downstream of where the bristles strike the surface such that the workpiece surface has a predetermined roughness after being struck by the bristles.
