Effect of crystallography on residual stresses during ultra-precision machining of sapphire

CIRP annals, 2022
Residual stresses play an important role in determining the quality of a machined surface during ultra-precision machining (UPM) of ceramics by initiating cracks at premature loads. In this study, the anisotropy in residual stresses resulting from UPM of

Ultra Precision Machine Tools

2004
The growth of the ultra precision technologies, precision engineering, micro engineering and now engineering nanotechnology is, naturally, closely related to the development of ultra precision machine tools (UPMTs). Among the first ultra precision machine tools to appear on the world stage were diamond turning machines at the U.S.

Sustainable production of dry-ultra-precision machining of Ti–6Al–4V alloy using PCD tool under ultrasonic elliptical vibration-assisted cutting

, 2020
The Ti–6Al–4V alloy is regarded as a typical hard-to-machine material owing to its small thermal conductivity and low deformation coefficient. Large amounts of cutting fluids are required and consumed in the traditional ultra-precision machining of the ...

Ultra-precision machining process of inner surface considering shear-thickening polishing method

Proceedings of the Institution of mechanical engineers. Part B, journal of engineering manufacture
Shear-thickening polishing (STP) is a non-traditional flexible ultra-precision processing method that exploits the polishing fluid’s shear-thickening properties to create a shear rate between the workpiece surface and the potential flow.

Ultra-Precision Float Polishing Machine

CIRP Annals, 1987
Abstract A new ultra-precision float polishing machine which can cut a tin lap of 460 mm in diameter very flat with a sharp diamond tool has been developed for polishing samples up to 180 mm in diameter. The conventionally pitch-polished BK-7 glass, Zerodur, Cer Vit and fused silica of 100 mm in diameter were polished to the flatness of λ/20 = 0.03 ...
