Atomic level simulation of cutting


The density functional theory and pseudopotential method are used to study the interaction of nanoscale species of different origins. It has been shown that the low-speed cutting is followed with diffusion intermixing and plastic deformation and leads to the intensive destruction of a cutting instrument. At high-speed cutting intermixing and plastic deformation doesn’t manage to happen, a cutter does not destruct, and cutting goes more smoothly. The cutting force decreases with increase of speed.
