Shear-thickening polishing (STP) is a non-traditional flexible ultra-precision processing method that exploits the fluid’s shear-thickening properties to create shear rate between workpiece surface and potential flow. This increases viscosity achieves material removal. In past, was mostly employed for outer of rotating bodies. Nevertheless, apply STP workpiece’s inner surface, this paper proposes an active formed layer based on numerical calculation model. Additionally, main parameters affecting machining efficiency were identified, orthogonal experiments performed process parameter levels, optimal conditions derived. The optimized adopted machine large-size bearing ring, roughness in terms R reduced from original 131.27 27.14 nm 30 min further 19.52 60 min. validation highlight model can predict experimental results accurately, demonstrating proposed method’s feasibility with method.

Magnetorheological finishing (MRF) is a deterministic optical processing technique based on CCOS that achieves high removal efficiency and accuracy while reducing subsurface damage. This still suffers from multiple iterations of due to variations in the inability fully correct mid-frequency errors below cut-off frequency function. For above problems, this paper attempted establish error model function change for predicting MRF efficiency. Based analysis distribution surface shape residuals under different machining paths, process combining spiral scanning raster proposed, which can realize correction restrain deterioration errors. The experimental results show when low-frequency fused silica element converge rapidly, by optimizing coefficient using combined method, PSD lower than initial value, expands route high-precision elements.
