Tool wear mechanism in diamond turning of copper is investigated by thermodynamics analysis and an erosion test which simulates the wear process. The mechanism involves the removal of carbon atoms on tool face due to oxidization accompanied with deox

Based on the discussion in which the defect as a source of cracks must be created during cutting a silicon monocrystal, the renormalization group molecular dynamics has been proposed to simulate the defect initiation process. The method can be applie

The authors have reported in a previous paper that the twist-roller friction drive can realize sub-nanometer positioning resolution. However, a structural difficulty of the device is that hydrostatic bearings are used to support the twist-rollers. Th

A generalized hypothesis for the brittle to ductile transition in micromachining and microindentation of brittle materials is proposed. By the hypothesis, complicated transition phenomena observed in practical machining processes are well explained.
