Abstract: Magnetorheological abrasive flow finishing (MRAFF) process has been developed for nanofinishing of parts especially for complicated geometry for a wide range of industrial applications. The finishing efficiency and finishing quality of MRAFF process relies mainly on the rheological properties (i.e., yield stress and viscosity) of magnetorheological polishing (MRP) fluid which must be characterised before it is used in any specific application. These properties are responsible for bonding strength of abrasive particles surrounding carbonyl iron particle (CIP) chains. Design of MRP fluid composition and volume ratio has an impact on rheological properties and stability directly. Response surface methodology (RSM) is applied to predict the effect of volume concentration of each component on yield stress and viscosity of MRP fluid.

Keywords: magnetorheological abrasive flow finishing; MRAFF; magnetorheological polishing fluids; MRP fluids; carbonyl iron particles; response surface methodology; RSM; magnetorheological finishing; magnetorheology; nanofinishing; yield stress; viscosity.
