Determination of the Minimum Depth of Cut in Nanometric Machining Using Molecular Dynamics Simulation

Abstract:

The Minimum Depth of Cut (MDC) is a major limiting factor on achievable accuracy in nanomachining, because the generated surface roughness is primarily attributed to the ploughing process when the uncut chip thickness is less than the MDC. This paper presents an evaluation of a cutting process where a sharp diamond tool with an edge radius of few atoms acts on a crystalline copper workpiece. The molecular dynamics (MD) simulation results show the phenomena of rubbing, ploughing and cutting. The formation of chip occurred from the depth of cut thickness of 1-1.5nm.
