Abrasive flow machining is considered to be a scratching action performed by abrasive grains in the AFM media. The normal force applied to a spherical grain will cause it to penetrate in the surface (Fig. 3 (a)) [15]. The grain produces a groove on the workpiece surface whose section corresponds to the profile of the grain.
