Patent ID: 8892238

Claim:
A method for smoothing an edge of a part, the edge defined by a first planar surface and a second planar surface, the method comprising: operating a rotating polishing wheel comprising a polishing surface in accordance with a first set of polishing parameters to form a first curved surface at the edge and the first planar surface, the first set of polishing parameters comprising a first set of rotational speeds, a first set of translational speeds and a first contact angle of the polishing surface relative to a horizontal reference line relative to the first planar surface; and operating the rotating polishing wheel in accordance with a second set of polishing parameters, different that the first set of polishing parameters, to form a second curved surface at the edge and the second planar surface, the second set of polishing parameters comprising a second set of rotational speeds, a second set of translational speeds and a second contact angle of the polishing surface relative to the horizontal reference line relative to the first planar surface different than the first angle, wherein the first curved surface and the second curved surface cooperate to form the smoothed edge.
