The MD simulation models with the number of atoms in the workpiece being arounda2 millions,b4 millions andc10 millions. The corresponding workpiece dimensions are 40 × 20 × 30 nm, 40 × 40 × 30 nm, and 70 × 44 × 40 nm, respectively. The cutting tools are in light grey color and the cutting chips ahead the cutting tools are shown in colors ranging from red to light blue
