Summary: This paper presents an experimental investigation on ultrasonic vibration-assisted magnetorheological finishing (VAMRF) process for improved material removal rate (MRR) and surface finishing on glass optics polishing. The results show that hybrid VAMRF provides approximately 20% higher MRR and better surface micro-roughness improvement compared to conventional Ball End MRF (BEMRF). The developed hybrid process is applied in corrective polishing of glass optics and reduces the figure error (RMS) of the surface significantly.

Summary: Magnetorheological finishing fluid (MRFF), consisting of magnetic particles, base carrier fluid, abrasives and additives, is critical for achieving magnetorheological deterministic finishing. Stable MRFF was prepared using solvothermal and calcination reactions to produce flower-like Fe3O4 as the magnetic particles. Compared to spherical-Fe3O4, the magnetic chain bundles composed of flower-like Fe3O4 exhibited stronger holding force and a 10.37% increase in shear force during the polishing process. Experimental results showed that polishing with flower-like-Fe3O4 MRFF could achieve deeper material removal depth, with a maximum increase of 41.5% under the same conditions.

Summary: This study proposed a high-efficiency nano-polishing approach for processing spherical surfaces of bearing steel, achieving high-quality ultra-precision finished surfaces. By exploring the rheology of the polishing slurry and investigating controllable parameters experimentally, it was found that the surface roughness and material removal rate can increase simultaneously when applying a small abrasive size due to the thickening mechanism. Under optimized conditions, a high-accuracy spherical bearing steel surface was achieved, demonstrating a potential ultra-precision machining method for target materials.

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.
