Summary: In this study, the feasibility and characteristics of polishing elliptical elements using a doughnut-shaped MCF polishing tool were investigated through experimental research. The results showed that the middle portion of the polishing tool had the best material removal ability, and different polishing slurries had varying effects on surface roughness and glossiness. Additionally, the working gap, revolution speed, and polishing time also influenced the polishing results. The microstructure of the MCF polishing tool after polishing revealed even distribution of abrasive particles grabbed by ferric clusters, with alpha-celluloses interleaved between the clusters.

Summary: In this study, the formation mechanism and evolution of surface roughness in the cylindrical shear thickening polishing process were investigated theoretically and experimentally. The elastohydrodynamic properties and the surface roughness were modeled using a novel solution method. Through Taguchi orthogonal tests, an experimental surface roughness Ra of 9.689 nm was achieved under specific conditions. The effecting mechanisms of processing factors on the surface roughness were interpreted from the perspective of viscosity, pressure distribution, and single grain's cutting depth, showing significant differences from traditional polishing methods.

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.
