“…Existing research has shown that there is a strong correlation between the parameters (frequency and amplitude) of vibration and the surface quality after polishing. , Gu et al developed a two-degree-of-freedom vibration-assisted polishing device driven by PZT. The polishing experimental results showed that the MRR was increased by 24.1–33.7%, and as the vibration parameter (amplitude and frequency) increased, the Sa decreased.…”

The problems of low polishing efficiency and serious surface damage in the processing of silicon carbide (SiC) ceramics are well-known. In view of the above problems, a new method of photocatalytic vibration composite polishing (PVCP) combined with a compound control strategy was proposed. A vibration-assisted device was developed, and a compound control system was designed for the device to improve the trajectory tracking accuracy. Experiments were carried out to verify the effectiveness of the vibration-assisted device and the compound control system. In addition, methyl orange degradation and fading experiments, redox potential measurement experiments, and SiC ceramic surface hardness characterization experiments were carried out to reveal the effects of vibration and photocatalytic parameters on polishing solution oxidation and SiC ceramic surface mechanical properties. Finally, the effects of photocatalysis, vibration frequency, amplitude, and the compound control system on the polishing effect were analyzed. The results show that when the UV intensity is 100%, the polishing force is 3−4N, the vibration frequency is 400 Hz, the amplitude is 15 μm, and the surface roughness of SiC ceramics is reduced by about 11 nm after the introduction of the compound control system, which verifies the effectiveness of the combination of the compound control system and PVCP.

“…This characteristic renders it flexible and easily adherent to the machined surface, positioning this process as an emerging precision machining technology with great potential [4][5][6]. Numerous studies have explored MRF in recent years, finding diverse applications in fields such as medical and optical part machining [7][8][9]. Harris et al [10] elucidated the polishing characteristics and the material removed principle of MRF, affirming its capacity for precise finishing.…”

In the pursuit of advancing the surface machining efficiency of Ti-6Al-4V material through magnetic polishing, this study introduces a new approach methodology. A novel approach integrates Magneto-Rheological Finishing (MRF) into a circulating system, employing a circular Halbach array to ensure a continuous and uniform flow of magnetic abrasives. Employing simulation and theoretical analysis, MRF polishing processes with the fluid dynamics of abrasive (SiO2) and magnetic particles (Fe3O4) during the finishing process of Ti-6Al-4V material using a circulating conveyor designed for the regeneration of abrasive particles. To investigate the impact of magnetic fluid distributions influenced by magnetic fields on the machining process, we meticulously conduct experimental analyses. The findings underscore that diminishing the working distance results in an expanded distribution range of magnetic abrasive fluid on the conveyor belt. Consequently, this induces a noteworthy variation in impact positions on the workpiece surface, leading to an increased exposed area. A pivotal outcome of this study is the observed augmentation in machining quality and efficiency. Remarkably, the surface roughness of the Ti-6Al-4V workpiece undergoes a substantial improvement, diminishing from an initial Ra = 431.1 nm to an impressive Ra = 39.6 nm within a 30-minute timeframe.
