Assessment of Ultra-Precision Machined Surfaces
Materials and Manufacturing Processes, 2000Abstract This paper reviews the theory and evaluation of ultraprecision-machined surfaces. Carbide and single crystalline diamond tools were used to machine brittle, ductile and metal matrix composites in macro and micro scales. Data for ductile mode micromachining of brittle materials (silicon, Al2O3, SiC) and ductile materials (Cu-Be, Cu-Zn, Al-Si ...

Ultra-Precision Float Polishing Machine
CIRP Annals, 1987Abstract 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 ...
