“…Therefore, the improvement in surface finish and time-taken to achieve the final surface finish in the present work is found far better than the already developed internal MR finishing process. 1,23 Such extent of improvement in the surface finish obtained in the present MR finishing work is due to the simultaneous rotating and reciprocating motion of the active abrasive particles on the internal surface of the counter-rotating hollow cylindrical workpiece.…”

The particles used in magnetorheological polishing (MRP) fluid are the key components of the magnetorheological (MR) finishing processes. The rotational magnetorheological honing (R-MRH) process is recently developed as a highly productive MR finishing process which is used for finishing the internal surface of the industrial cylindric components. The involvement of micron-sized abrasive particles of MRP fluid in the finishing operation results in the invisible observation of the finishing mechanism which enables the urge of analyzing the motion of the particles during the present R-MRH process. Therefore, the effect of motions of the MRP-fluid’s particles is analyzed for nano-finishing performance on the inside surface of the cylindric workpieces. The motions performed by active abrasive particles on the inside surface of the rotating hollow cylindric workpiece cause a higher finishing rate. The effects of particle motions on the reduction in surface roughness and improvement in surface morphology confirm the usefulness of the R-MRH process. The surface finish with the effect of the particles' motions of the MRP-fluid in the R-MRH process on the stationary workpiece’s inner surface is achieved upto 100 nm from 420 nm of the initial ground surface in 60 min of finishing. Whereas, the same aforementioned surface of the rotating workpiece is finished upto 50 nm from the same initial ground surface in only 40 min of finishing with the effect of the particles' motions of the MRP-fluid. The improvement in the surface finish is also noticed through the scanning electron micrographs in this work. The significant change in surface finish obtained in experimentations confirms the integrity of the analytical study conducted for understanding the effects of motions of particles while finishing with the R-MRH process.

“…3 In the MRH process, the electromagnet is placed inside the cylindrical workpiece. 69 When the ferromagnetic workpiece is finished by the MRH process, the magnetic field is more on the tool surface and lower at the workpiece surface as presented in Figure 12a. Further, the retained MR polishing fluid on the tool surface due to the magnetic field can be used for attaining superior surface quality.…”

Modern technology requires producing of a sustainable product with a high surface accuracy. In applications where the surface quality is highly considerable in various internal cylindrical components requires technology to manufacture an ultrafine surface finish. There is, in general, a probability of inducing errors into products by the traditional finishing processes (such as grinding/honing), which lead to failure. Preferably with some evidence in the main text. Further, the advanced finishing processes are developed, where the finishing forces can be controlled by varying the power output. Instead of a solid abrasive tool, the smart polishing fluid is used, which gets activated under the magnetic fields. In this manuscript, the material removal under different internal surface finishing processes is elaborated, which helps in improving the surface quality of various industrial components. Also, the surface quality produced on various industrial components after traditional as well as advanced finishing processes are discussed.

“…Also, it is used to finish the through-hole internal surface of the cylindrical non-magnetic stainless steel tubes and pipes [16,17]. To finish the internal cylindrical surfaces of ferromagnetic work material, a new MR honing process using electromagnets is developed [18]. Further, to finish the different size of the through-hole internal cylindrical surfaces of the cylindrical-shaped workpieces, the improved MR honing processes have been developed [19,20].…”

Permanent mould dies are used for various plastic injection moulding products. Most of the mould cavity is blind and henceforth difficult to finish. In this study, a novel magnetorheological fluid-based finishing process using permanent magnet tools has been developed for nano-finishing of cylindrical blind hole surfaces. Tools to finish the internal and flat-bottomed surfaces of the cylindrical blind hole are developed. The finishing performance of both tools is evaluated for finishing ferromagnetic material used in dies. The material of the die is P20 tool steel having 41 HRC hardness. Response surface methodology using a central composite design technique has been utilized for the plan of experiments and analysis of significant process parameters on the percentage change in surface roughness using newly developed tools. During finishing the internal cylindrical blind hole surface, the process parameters like rotational speed, reciprocation speed and abrasive mesh size are found to be significant. However, during flat-bottomed surface finishing of cylindrical blind hole workpiece, rotational speed, abrasive mesh size and abrasives volume percentage are found to process significant parameters. Experimentation at optimized parameters results in the final surface finish of 83 nm on internal cylindrical surface and 93 nm on the flat-bottomed surface of cylindrical blind hole workpiece.
