Controlled Shaping of Precision External Cylindrical Surfaces

A theoretical method is proposed for determining the duration of abrasive finishing of cylindrical external surfaces. The method takes account of the initial geometric deviation, the productivity, and the kinematic parameters. By this means, the machining time may be established, taking account of the operations involved, and the best finishing conditions for precision surfaces may be established, so as to ensure the required surface roughness ( R a no greater than 0.2 µm) and geometric precision (deviation from cylindrical form no more than 0.002 mm).
