Single-crystal germanium (Ge) has been widely used in infrared optics and ultra-precision
components, however, the appearance of alternating brittle and ductile fan-shaped patterns …

Ultra-precision fly cutting (UPFC) is an important technology in the fabrication of freeform
surfaces on single-crystal silicon. However, the insufficient understanding of the ductile …

The desire for quality infrared lens with better surface finish has brought about the usage of
brittle materials like germanium to be machined via a single point diamond turning …

The cutting mode transition from ductile to brittle is related to the depth of cut for the
machining of brittle materials. The critical depth of cut for ductile to brittle transition (DBT) …

The theoretical model of cutting force in turning metal materials is not applicable to the
machining of hard-brittle materials. This view is also supported by experimental results …

The single-point diamond turning (SPDT) procedure can provide the desired surface polish
of optical components as well as form accuracy. The diamond tool used in the SPDT method …

This article summarizes laser assisted single point diamond turning (SPDT) of select brittle
and hard materials, using the μ-LAM process. These materials all have significant industrial …

An experimental study is reported to characterise the femtosecond (FS) laser grooving
process for Germanium (Ge) substrates. The effects of process parameters, including laser …

Традиционная технология обработки поверхностей деталей из хрупких оптических
материалов предусматривает предварительное шлифование алмазными кругами с …

Germanium is a widely used material in the infrared range. Single crystal germanium is used
