CFD analysis and Optimization of Abrasive Flow Machining

Abstract

This study deals with a new approach to understand the micro finishing of abrasive flow machining process in which computational fluid dynamics is used to simulate the forces. Mathematical modelling is applied to model the micro finishing operation. The study is conducted to compare the simulated results with the existing experimental results. A flexible polishing tool comprising polishing medium is used to carry out the analysis. The relative motion between the polishing medium and the workpiece surface provides the required finishing action. In the present work a two dimensional computational fluid dynamics simulation inside the workpiece fixture is performed to evaluate the axial and radial stresses developed due to the flow of polishing medium. The present study also develops optimization for AFM process of Al. alloy using response surface method.
