# Effect of crystallographic orientation on single crystal copper nanogrooving behaviors by MD method

## Abstract

This study used a molecular dynamic (MD) method to study the grooving behaviors of single crystal of copper cut with a rigid diamond tool. The crystallographic orientation effects on cutting force and groove morphology are discussed by metallurgical viewpoint. The grooving crystal planes and directions included $$(001)\left[\overline{1}00\right]$$, $$(101)\left[\overline{1}01\right]$$, and $$(101)\left[0\overline{1}0\right]$$. The MD simulation results showed that crystal orientation significantly affected the grooving behaviors of single crystal copper. The cutting along different orientations led to the number of slip system difference. The simulation results showed that grooving on (101) along $$\left[0\overline{1}0\right]$$ direction with a rectangular tool can obtain the suitable rectangular slot but get a groove with “V” shape cross section in $$(101)\left[\overline{1}01\right]$$ grooving.
