Magnetorheological-suspension-based finishing technology

Creation of perfect surfaces

“…So, if machining accuracy or surface roughness of the requirement cannot be obtained using the PCVM machine, the finishing process will be carried out by the NC-EEM machine shown in Fig. 5 against other techniques [10][11][12][13][14][15][16][17][18][19][20][21] are shown in Fig. 10.…”

Nanofinishing of a typical 3D ferromagnetic workpiece using ball end magnetorheological finishing process

“…The normal force on an abrasive particle in MRF is relatively small as compared to traditional finishing techniques because material removal in MRF is regulated by shear stress [3]. Magnetorheological (MR) fluids are the key element of magnetorheological finishing process [4]. MR polishing fluids consist of magnetic carbonyl iron powder (CIP), polishing abrasives, carrier fluid, and stabilizers.…”

Optimum selection of machining parameters in ball end magnetorheological finishing process

“…On the development of new kinds of materials, the engineers are facing challenges for finishing these materials to meet their functional requirements. Kordonski et al (1998) explained that the material removal occurs by mechanical energy which is obtained by hydrodynamic flow of MRP suspension through the converging gap and found reduced surface micro roughness of optical work-piece. In the last few decades, some advanced finishing processes such as abrasive flow machining (AFM), magnetic abrasive finishing (MAF), magnetic float polishing (MFP) and magnetorheological finishing (MRF) have been developed.…”
