CFD Analysis and Optimization of Process Parameters of Abrasiveflow Machining

Abstract

This study deals with an approach to understand the micro finishing of abrasive flow machining process, in which computational fluid dynamics is used to simulate the forces. The present work develops a CFD simulation of AFM of a cylindrical work-piece and a work-piece with irregular feature. Velocity profile and pressure distribution has been determined for a given extrusion pressure. Axial stress, radial stress and depth of indentation have been determined. Taguchi’s technique is used to minimize the depth of indentation. A flexible polishing tool comprising of a polishing medium is used to carry out the analysis. It is found that mesh size has significant effect on outputs followed by velocity and pressure. The simulation is also partially validated with experiments
