Abstract

Molecular dynamics (MD) simulations are performed to study the nanometric cutting process of CaF2. The results show that the relative orientation between cutting direction and slip system {100}〈011〉 has great influence on the mechanism of chip formation. When their relative orientation favours slipping of atoms on the slip system, slipping on the slip system becomes the main mechanism of chip formation. Otherwise, amorphous phase transformation and shearing in the amorphous region is primarily responsible for chip formation. When tool rake angle becomes negatively larger, shearing in the amorphous region plays a greater role in chip formation.
