Diamond turning of steel in carbon-saturated atmospheres

Tool wear control in single-crystal diamond cutting of steel by using the ultra-intermittent cutting method

“…While several research projects [1][2][3] have addressed ultraprecision cutting of steel with diamond tools, they have not necessarily been successful in achieving both long tool life and optical-quality surfaces. Shamoto, Moriwaki and coworkers [4][5][6][7] reported that hardened stainless steel could be cut with ultrasonically vibrated diamond tools, and that optical-quality surfaces could be obtained for long cutting lengths.…”

Interferometric measurements of single crystal diamond tool wear

“…The importance of the chemical aspects has been underlined by studies of diamond wear and erosion in a variety of gaseous environments [4][5][6], the reduction of diamond wear through high frequency interrupted cuts (e.g. [7]), and the development of ''diamond turnable'' steels by nitriding [8].…”

The Many Facets of Diamond Crystals

“…This hinders many important applications where ultra-precision machining of steel alloys is required. In order to reduce this catastrophic tool wear, certain process modifications have been proposed in the literature, including use of different carbon-saturated atmospheres [62], cryogenic [63], and ultrasonic assisted [64] turning, and others. However, the problem has not been still solved satisfactorily, that stimulates further investigations.…”
