Abstract	The finishing action in magnetorheological abrasive flow finishing (MRAFF) process relies mainly on bonding strength around abrasive particles in magnetorheological polishing (MRP) fluid due to cross-linked columnar structure of carbonyl iron particles. The fluid flow behaviour of MRP fluid exhibits a transition from weak Bingham liquid-like structure to a strong gel-like structure on the application of magnetic field. Depending on the size and volume concentration of abrasives and carbonyl iron particles (CIPs) in the base medium, the rheological properties hence, bonding strength gained by abrasives through surrounding CIP chains varies. To study the effect of particle size on rheological properties of MRP fluid, a hydraulically driven specially designed capillary magnetorheometer was fabricated. The rheological properties of MRP fluids in the homogeneous magnetic field perpendicular to the shear flow direction are evaluated. The three constitutive models, viz. Bingham plastic, Herschel–Bulkley and Casson’s fluid, are used to characterise the rheological behaviour of MRP fluid by fitting the rheological data obtained from capillary magnetorheometer and evaluating respective constants in their constitutive equations.
