Abstract:In order to realize ductile machining of optical glasses using mono-layer nickel
electroplated coarse-grained diamond grinding wheel, a novel conditioning technique features using
a copper bonded diamond grinding wheels of 15m grain size dressed by ELID (electrolytic inprocess
dressing) to condition the 46m grain sized diamond wheel has been developed. During the
conditioning process, a force transducer was used to monitor the conditioning force, a coaxial
optical distance measurement system was used to in-sit… Show more
“…Another approach to escape the dilemma of ductile-mode grinding has been proposed by Zhao et al [29]. Wear of the grinding wheel could be reduced to an acceptable level if coarse-grained wheels with an average grain size larger than 100 mm could be employed.…”
Manipulating bulk material at the atomic level is considered to be the domain of physics, chemistry and nanotechnology. However, precision engineering, especially micromachining, has become a powerful tool for controlling the surface properties and sub-surface integrity of the optical, electronic and mechanical functional parts in a regime where continuum mechanics is left behind and the quantum nature of matter comes into play. The surprising subtlety of micro-machining results from the extraordinary precision of tools, machines and controls expanding into the nanometre range-a hundred times more precise than the wavelength of light. In this paper, we will outline the development of precision engineering, highlight modern achievements of ultra-precision machining and discuss the necessity of a deeper physical understanding of micro-machining.
