    An early multi-axis single point diamond turning machine During this era, the use of ultra-precision machining continued to revolve around the core technology of single point diamond turning. As such, the process was limited to those materials that could be machined by a . were performed with other diamond tools different from those used for experiments, providing a mirror-like surface. Diamond tools Most of previous studies on diamond turning of brittle materials involve the use of a round-nosed diamond tool [1–4,9,13,16]. In this case both undeformed chip thicknessFile Size: KB.

Khan. Ultra-precision single point diamond turning is a key technology in the manufacture of mechanical, optical and opto-electronics components with a surface roughness of a few nanometers and form. The single point diamond turning process has been used extensively for direct optical surface fabrication.

However, the diamond machined surfaces have characteristic periodic tool marks, which contribute to reduced optical performance such as scattering and by:   An accurate spiral tool path generation method of ultraprecision three-axis turning free form surface is proposed based on symbolic computation in this paper.

Many analytic optical free form surfaces often need to be machined to submicron in form error, such as optical nonaxisymmetric aspheric surfaces, but current mainstream CAM systems usually use nonuniform rational basis spline (NURBS) Cited by: The CCUP is a complex process and is quite different from other ultra-precision machining processes such as single point diamond turning and raster milling; the surface generation by CCUP is dominated by the polishing Tool Influence Function (TIF) instead of the pure geometry of cutting by: His other significant activity involves the growth of diamond turn machining community both in the country and globally.

He has more than publications to his credit apart from contribution chapters on Diamond Turning, Nano Finishing and Micro-Turning in text books on micro-machining. Diamond turning is used primarily to manufacture ultra precision parts for advanced applications, those that call for extremely high levels of form accuracy and surface finishing.

Such applications can be found in a number of industry sectors, including aerospace. The goal of this book is to familiarize professionals, researchers, and students with the basics of the Diamond Turn Machining Technology and the various issues involved.

The book provides a comprehensive knowledge about various aspects of the technology including the background, components of the machine, mechanism of material removal.
