“…It is worth noting that the ultrasonic vibration limits the operating frequency while improving the MRR; moreover, poor dynamic accuracy is still inevitable. Different from the ultrasonic vibration devices, the nonresonant vibration-assisted devices (later referred to as a vibration-assisted device) can provide a wider range of amplitude bandwidth and operating frequency. , Therefore, a vibration-assisted device is developed in this study, which combines VAP technology with PCAP technology and introduces a control strategy. On the one hand, the removal ability of an abrasive is improved, and on the other hand, the photocatalytic reaction rate is also improved.…”

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.

“…However, traditional techniques often result in SiC particle fracture, fragmentation, and pit, which can adversely affect the overall performance and stability of a workpiece [6,7]. A large number of studies have shown that vibration-assisted machining (VAM) and laser-assisted machining (LAM) methods can improve the machinability of SiCp/Al composites [8][9][10][11].…”

Silicon carbide particle-reinforced aluminum matrix composites (SiCp/Al) find diverse applications in engineering. Nevertheless, SiCp/Al exhibit limited machinability due to their special structure. A pulsed laser ultrasonic vibration assisted cutting (PLUVAC) method was proposed to enhance the machining characteristics of SiCp/Al and decrease surface defects. The finite element model was constructed, considering both the thermal effect of the pulsed laser and the location distribution of SiC particles. The model has been developed to analyze the damage forms of SiC particles and the formation mechanisms for the surface morphology. The influence of pulsed laser power on average cutting forces has also been analyzed. Research results indicate that PLUVAC accelerates the transition from the brittleness to the plastic of SiC particles, which helps to reduce surface scratching caused by fragmented SiC particles. Furthermore, the enhancement of surface quality is attributed to the decrease in surface cracks and the beneficial coating effect of the Al matrix. The accuracy of the simulation is verified by experiments, and the feasibility of PLUVAC method to enhance the surface quality of SiCp/Al is confirmed.

“…The trajectory not only improves material removal rate but also reduces periodic polishing marks. Gu and Kang et al [26,27] proposed the nonresonant vibration-assisted magnetorheological polishing method based on the two-dimensional non-resonant vibration and permanent magnet polishing head. The additional impact tangential force generated by the vibration acting on abrasive particles not only significantly reduces the surface roughness but also increases the material removal rate.…”

Magnetorheological finishing (MRF) is an important technique to achieve the surface precision of difficult-to-cut materials. In this paper, a wheel-type vibration-magnetorheological compound finishing is proposed in terms of reducing the unidirectional scratch caused by the wheel type magnetorheological finishing tool and further improving the convergence rate of surface roughness. The vibration-magnetorheological coupling was realized through utilizing designed magnetorheological finishing (MRF) wheel and a nonresonant vibrational device (NRVD). Through the theoretical and experimental analysis, the surface roughness has been verified improved through increasing the normal and tangential forces, which are associated with introducing 2D vibration. The flow and viscoelastic models of the MRP fluid were established based on hydrodynamic lubrication and viscoelasticity theories. Finally, the feasibility of the proposed finishing method was verified by the results of improving surface roughness through designing reasonable processing experiment.
