- W3125456211 abstract "Abstract Titanium is a popular metal with good strength-weight ratio, high resistance to corrosion and can withstand higher temperatures. Titanium and its alloys are widely used in the aerospace industries. As the experimental tests for titanium are costly and Finite Element Method analysis do not permit observation of deformation defects occurring at the atomistic scale, at shorter time scales, Molecular Dynamics analysis tool has been used to study the machining process at the atomistic scale. The small dimension of workpiece, reduced depth of cut and cutting speed bring up several issues that may not play any significant role in conventional machining but are of significant importance in micro and nano-level cutting process. During Machining, an increase in dislocation density occurs at the machined surface, due to this plastic deformation on these upper layers of the machined surface. Previous work on machining at the nano-scale has been performed for Copper, Aluminum and Silicon with a focus on different potential energy functions, tool life, tool geometry and effect of cutting forces. In this present work, a molecular dynamics simulation study has been performed to investigate evidence of deformation on the machined surface and subsurface layers during machining of monocrystalline titanium workpiece with a rigid diamond tool at nanometric scale using different cutting speeds. The distribution of deformation factors including stress, strain, strain rate, the temperature in the machined surface and sub-surfaces are analyzed at various cutting speeds given the same other conditions." @default.
