“…Accurate magnetic field-assisted finishing models that take into account MRR and surface quality constraints are sought for. Many models for MAF and MRF recently reported have aimed to fill this gap and to better understand the way input parameters affect MRR and roughness [ 66 , 76 , 90 – 92 ].…”

The need for ultraprecision finishing has grown, and magnetic field-assisted finishing has shown potential for overcoming some challenges. This study evaluates the scientific production and identifies future directions of magnetic field-assisted finishing based on a bibliometric analysis. Using Bibliometrix, network mapping and descriptive analysis were performed on 1558 documents related to magnetic field-assisted finishing-related research published over the past 51 years. The results of the comprehensive literature reviewed showed that the theme exhibits a rising trend of 56% in the last 10 years, being mainly conducted by Chinese, Indian, and American researchers. Different geometries and materials can be finished and which had surface roughness ranges from sub-nanometer- to micrometer-scale. Surface finishing of freeform dies and molds, optical components, and medical devices have been standing out as current process applications in tooling, aerospace, and biomedical industries. AISI 304 stainless steel was the most tested metal. Finally, potential areas of research were identified in the coming years, which could lead to new fields of application for magnetic field-assisted finishing in industry.

“…Liu et al [7] established a tool influence function for aspheric workpieces based on the Reynolds Equation to reveal the effect of gap thickness variation on the material removal rate. Ghosh et al [8] experimentally analyzed the effect of the cross-feeding method of a wheel-type MRP machine on surface roughness, established the evaluation function of working gap thickness and wheel speed on the processing results, and provided a new basis for the processing parameters optimization. Ren et al [9] proposed a Belt-MRF concept to expand the application of MRF to large mirrors and made a prototype with a large remove function, using a belt instead of a very large polishing wheel to expand the polishing length.…”

A planetary-type cluster magnetorheological polishing device with a rotating magnetic field was proposed to solve the problems of abrasive accumulation and low polishing efficiency caused by the untimely restoration of the conventional magnetic chain. Considering the microstructural deformation and squeeze-strengthening effect of magnetorheological polishing fluid, a material removal rate model was established based on the principle of fluid dynamic pressure and verified by experiments. The relationships between material removal rate or roughness and processing parameters were confirmed by multiple linear regression analyses, respectively. And the processing parameters optimization was made by linear weighting method under the premise of establishing the evaluation system. The results show that the eccentricity and angular velocity ratio are proportional and inversely proportional to MRR, respectively. When the polishing fluid is squeezed, the material removal rate can be significantly increased from 7nm/min to 21nm/min, but the roughness will be reversed at a gap of less than 0.9mm. After the optimization of processing parameters, the workpiece roughness after rough and fine polishing was reduced from 1.079µm and 1.083µm to 0.346µm and 0.184µm, with a reduction of 67.9% and 83.01%.

Purpose This paper aims to study the effects of the different processing parameters in the reciprocating magnetorheological polishing (RMRP) on the surface roughness (Ra) and material removal rate (MRR) of the workpiece surface. Design/methodology/approach The principle of RMRP method is discussed, and a series of the single factor experiments are performed to evaluate the effects of the workpiece’s rotational speed, the reciprocating frequency, the magnetic field strength, the working gap and the processing time on machining results using the RMRP device. Findings The RMRP method is effective and practical for K9 glass polishing, and the optimized processing parameters are obtained by the single factor experiments of RMRP. The surface roughness of the workpiece is reduced from 332 nm to 28 nm under optimized processing parameters. Originality/value In the present study, the RMRP method is proposed, and a system of experiments is carried out using the RMRP device. The RMRP device can improve the surface roughness and MRR of the K9 glass significantly. Furthermore, the test results provide references for reasonable selection of the processing parameters in magnetorheological polishing process.
