Summary: In this study, a wheel-based magnetorheological finishing process was used to achieve nanolevel surface roughness on oxygen-free high conductivity copper. By adjusting the process parameters, it was found that a lower residual stress and minimal surface roughness could be attained by using a higher working gap, lower wheel speed, and feed rate.

Summary: This paper studies the influence of magnetorheological fluid (MRF) on the wear mechanism of sealing pairs under different surface roughness through theoretical analysis and experimental verification. The simulation analysis reveals that the coupling of roughness and microparticles changes the contact pressure and frictional stress distribution on the O-ring. The wear morphologies and analysis indicate that roughness affects the movement pattern of particles in the sealing gap, thereby determining the tribodynamic behavior of MRF. The study points out that the sealing wear under MRF is completely opposite to that of base oil.

Summary: Thermally sprayed tungsten carbide coating is widely used for wear resistance applications. In this study, magnetorheological fluid based finishing (MRF) process with diamond powder abrasive particles is used to achieve a nanolevel surface finish on pre-polished tungsten carbide coating. The incorporation of a chemical etchant in MRF results in a higher finishing rate. However, the MRF technique's effectiveness is limited at higher wheel velocities. To overcome this, CIPdiamond and CIP-diamond-graphene composite abrasives are introduced, which show higher material removal rates and better stability at elevated wheel speeds. The MRF process with CIPdiamond-graphene abrasives achieves the lowest surface roughness (Sa) of 55 nm and highest MRR.

Summary: In this paper, a novel OTA method is proposed that considers the relationship between tolerance of machine tools' key parts and volumetric error. A volumetric error prediction model is established based on the bridge between geometric error and tolerance. Additionally, a Processing Simplicity Index (PSI) is introduced to replace manufacturing cost and a tolerance-PSI model is established. An OTA model is formulated to minimize volumetric error and maximize PSI. The feasibility and effectiveness of the method are validated through simulations and experiments.

Summary: This paper studies the electromechanical behavior of elliptical APAs by analyzing the multi-domain dynamics of piezoelectric stacks and compliant mechanisms using a novel electro-mechanical transfer matrix method. An analytical electro-elasto transfer matrix of piezoelectric stacks operating at the d33 mode is derived in the form of Taylor's series. The dynamic response spectrum of displacement and impedance for elliptical APAs is accurately captured by this electro-mechanical model, and different topologies of elliptical APAs are compared to suggest the optimal configuration.
