ABSTRACT:
A workpiece has at least one exterior surface with an initial average surface roughness (Ir). The profile of the exterior surface is derived by conventional manufacturing processes, some of which leave the exterior surface with irregularities having directional orientation. The workpiece is subjected to a controlled vibratory finishing process such that the exterior surface has a desired average surface roughness (Ar) after exposure to the finishing process for a predetermine period of time (T.sub.opt). This predetermined period of time is based upon the initial average surface roughness (Ir), the desired average surface roughness (Ar) and a minimum average surface roughness obtainable through the vibratory finishing process (Dr).
