“…At present, there are various types of MRF devices, such as groove type [25], wheel type [25], belt type [246,247], disk type [248,249], cluster type [250,251], ball head type [252,253], etc, which are suitable for surface processing of various types and sizes, such as plane, concave, convex, inner surface, etc. The diameter of the polished workpiece is mostly more than 100 mm or even 1 m. The research status and characteristics comparison of MRF devices are shown in table 6.…”

“…After optimizing the process parameters, it was found that the surface roughness of BK7 glass could be reduced to 3.8 nm. Yin et al [248,249] explored the material removal rate under the influence of permanent magnet configurations by using a disc type MRF device, as depicted in figure 33(b). Permanent magnets of different configurations are placed under the polishing disc and form a gradient magnetic field distribution.…”

Difficult-to-machine materials (DMMs) are extensively applied in critical fields such as aviation, national defense, biomedicine, and other key fields due to their excellent material properties. However, traditional machining technology is difficult to precisely machine DMMs due to poor surface quality and low processing efficiency. In recent years, as a new generation of machining technology, field-assisted machining (FAM) technology based on innovative principles such as laser heating, tool vibration, magnetic magnetization, and plasma modification provides a new solution for improving the machinability of DMMs. It is advantageous to prevent the shortcomings of traditional machining methods, and has become a hot topic of research in the domain of ultra-precision machining of DMMs. Many new methods and principles have been presented and investigated one after another, yet few researches have been analysed and summarized from a comprehensive standpoint. To fill this gap and understand the development trend of FAM, this study provides an important overview of FAM, covering different assisted machining methods, application effects, mechanism analysis, and equipment design. The current deficiencies and future challenges of FAM are summarized to lay the foundation for the further development of multi-field hybrid assisted and intelligent field-assisted machining technologies.

A cluster magnetorheological (MR) plane polishing based on a combination of magnetorheological finishing (MRF) and cluster mechanism (arrange in a regular array) has been developed for large planar optical workpiece. In this paper, the polishing pressure of an individual MR micro-grinding head on workpieces was investigated, and the mathematical model for cluster MR plane polishing was established based on the Preston equation and the properties of the workpiece material. An arc-shaped polishing belt was processed on monocrystalline 6H-SiC and Si wafer by the cluster MR polishing apparatus which polishing disk inlaid with cylindrical flat bottom magnetic pole arrange in the same direction regularly and monocyclically. The profile of arc polishing belt's cross section and the surface morphology were observed and analysed to verify the obtained model. The abrasives with different size were found to have an equal effect on the processed surface because of the accommodatedsinking effect of the polishing pad constituted by the cluster MR micro-grinding head. It was found that the monocrystalline 6H-SiC and Si wafer were polished in a plastic mode with a smooth, damage-free surface.

As an essential link in ultra-precision machining technology, various new surface polishing technologies and processes have always attracted continuous in-depth research and exploration by researchers. As a new research direction of ultra-precision machining technology, magnetorheological polishing technology has become an important part. The polishing materials and magnetorheological fluids involved in the process of magnetorheological polishing are reviewed. The polishing principle, equipment development, theoretical research and process research of magnetorheological polishing technologies, such as the wheel-type, cluster-type, ball-type, disc-type and other types, derived from the magnetorheological polishing process, are reviewed. The above magnetorheological polishing technologies are analyzed and compared from the perspective of processing accuracy, processing efficiency and application range. The curvature adaptive magnetorheological polishing technology with a circulatory system is proposed to achieve high efficiency and high-quality polishing.
