... The research revealed the amplification effect of lateral magnetic field overlap caused by chain aggregation on shear stress and confirmed that local dipole rearrangement dominates the macroscopic rheological response, providing a theoretical basis for the design and engineering application of highconcentration magnetorheological fluids. Zhu's group [3] systematically reviewed and analyzed the current application status of ultrasonic vibration-assisted grinding technology in the processing of advanced materials. It provides a detailed introduction to ultrasonic processing, covering its basic principles, ultrasonic vibration systems, classification of ultrasonic vibrations, processing characteristics and effects of ultrasonic processing, aiming to offer theoretical insights and practical references for future research and engineering applications. ...

... In contrast, SiC p /Al composites with a lower volume fraction of SiC particles exhibit relatively lower hardness, with more uniform material removal during machining, resulting in generally better surface quality [4,5]. Conventional grinding (CG) of SiC p /Al composites causes grinding stress concentration and the abrasive grains directly and forcefully impact the SiC particles, leading to rapid grain wear and the development of various defects in the SiC due to the grinding force [6][7][8]. These issues become more serious in high volume fraction SiC p /Al composites, highlighting the need for an innovative machining process to reduce grinding force and minimize machining damage. ...

... Oil-based emulsions or lubricants have been substantially employed in grinding to reduce abrasive wear, prolong wheel lifetime, and improve ground surface quality [5][6][7]. The oil-based grinding fluids, however, often entail severe environmental issues as they often possess inherent toxicity and are non-biodegradable [8][9][10]. Therefore, considerable efforts have been directed towards developing water-based lubricants to address this issue [11][12][13]. ...

... This extensive melting results in a deeper molten pool that facilitates a more extensive redistribution of material across the surface, thereby achieving a smoother finish. In contrast, during the remelting steps, a shallower surface melting appears to be more efficient in smoothing out the remaining peaks and valleys [60], as the starting surface roughness is already low and thus promotes the effectiveness of this final remelting pass [21]. ...

... Thus, the workpiece has a certain surface roughness [32]. Micro-geometric features on a machined surface consisting of small peaks and valleys with small spacing are referred to as surface roughness, which is a key metric for assessing surface quality and is primarily determined by Ra and RSm [62][63][64][65]. ...

... However, the grinding process may cause some defects in the material: during the grinding of bone tissue, excessive grinding force may result in irreversible damage [28], such as excessive harm to the bone tissue and surrounding nerve tissues, which affects healing [29], Although bioalloys (such as titanium alloys) have good mechanical properties [30], microcracks or surface roughness may be generated during grinding, affecting their long-term stability [30]. Bioinert ceramics like alumina and zirconia, while having high hardness and wear resistance, are prone to brittle fracture or surface microcracks during grinding [31], which reduces their mechanical properties and may even affect their long-term use in the body [32][33][34][35][36]. Therefore, reducing grinding force during the process, improving the processing quality of bone tissue and replacement materials, and ensuring machining accuracy are important factors in the development of bone grinding technology [17,[37][38][39][40][41][42]. ...

... Nowadays, machining cutting with the assistance of ultrasonic vibration has received special attention, as it has been proven that it can reduce the force and temperature that are necessary for cutting. Simultaneously, it can improve the cutting performance, i.e. decrease the tool wear, promotes grain refinement, and vastly improve the surface topography (Gu et al., 2023;Zhang et al., 2024), which are closed related with contact fatigue life (Li et al., 2024;Lv et al., 2025). Ultrasonic vibration has been applied in cutting systems with the purpose of minimizing tissue adhesion and thermal injury (Yao et al., 2021) and enhances the machinability of titanium alloys (Liu et al., 2021;Tan et al., 2020;Zhu et al., 2025), such as longitudinal-bending hybrid ultrasonic vibration-assisted milling , two-bending hybrid ultrasonic vibration-assisted milling (Sun et al., 2025), longitudinal-torsional ultrasonic cryogenic cooling drilling system (Shi et al., 2024). ...

... Sigvant et al. [5] noted that the decrease in tool surface roughness substantially decreases the coefficient of friction. In addition to these approaches, micro-scale surface texturing has recently become a method for enhancing lubrication and reducing friction in tribological pairs [6][7][8]. The surface texturing can be achieved by using electrochemical machining [9,10], electrical-discharge micromachining [11], and laser-texturing processes [12][13][14][15]. ...
