Numerical Simulation of Orthogonal Machining of Gallium Nitride via Smoothed Particle Hydrodynamics

Abstract

Gallium Nitride is one of the best candidates for upcoming industrial revolution due to its
superior electrical properties over silicon. In the present work, we investigate the chip
formation, cutting force and effective stress in diamond machining of gallium nitride by
smoothed particle hydrodynamics approach based on Mohr-Coulomb material model. The
comparison of the effective stress as reported by molecular dynamics studies and that
predicted by the smoothed particle hydrodynamics simulation demonstrates the effectiveness
of the smoothed particle hydrodynamics model.
