Abstract
Surface roughness plays a vital role in functional requirements of a component. Abrasive flow finishing (AFF) is an advanced finishing process used to achieve micro/nanolevel surface finish in complex geometries, internal inaccessible pathways made up of difficult to finish material, etc. In order to control the process and improve its performance, it is important to understand the mechanism of finishing. In this paper, an attempt has been made to model the forces generated during AFF process using the rheological properties of the viscoelastic medium used in the process. Secondly, by using the calculated forces, simulation of the final surface roughness profile of the workpiece has been presented. The simulated results are in good agreement with the experimental results.
