Abstract: Abrasive flow finishing (AFF) is one of the advanced nano-finishing technologies which is especially used to finish products that are not easily finished by traditional finishing processes. Rheology of the medium used for finishing plays a vital role in determining the magnitude of finishing forces generated during AFF process which in turn determines the end finish of the components. The finishing forces are evaluated by studying the rheological properties of the AFF medium in the present paper. Theoretical model for calculating the change in surface roughness with respect to change in AFF stokes, extrusion pressure and weight percentage of plasticiser is developed. Theoretical results are compared with the experimental results. It is found that theoretically change in surface roughness increases with the increase in AFF strokes and extrusion pressure while it decreases with the increase in weight percentage of plasticiser.
