    Abstract

    The effect of depth of cut on multi-pass
    nanometric machining of copper workpiece with diamond
    tool was studied using the Molecular Dynamics (MD)
    simulation. The copper-copper interactions were modelled
    by the EAM potential and the copper-diamond interactions
    were modelled by the Morse potential. The diamond tool
    was modelled as a deformable body and the Tersoff
    potential was applied for the carbon-carbon interactions. It
    was observed that the average tangential and normal
    components of the cutting forces increase with increase in
    depth of cut and they reduced in consecutive cutting passes
    for each depth of cut. Also, the ratio of the tangential to
    normal force components decreases as the depth of cut
    increases, but remains fairly constant after 1.5nm depth of
    cut. The ratio of the cutting force to area decreases with
    increase in the depth of cut and remains constant after
    2.5nm depth of cut.
