TAILIEUCHUNG - The influence of cutting conditions and cutting tool geometry on the atomistic modeling of precision cutting

In this paper a molecular dynamics simulation of nano-metric cutting of copper with a diamond tool is presented. MD simulations require the determination of the interaction of the involved atoms through a function of potential for the materials involved in the analysis and the accurate topography of the studied area, leading to high demand of computational time. | The influence of cutting conditions and cutting tool geometry on the atomistic modeling of precision cutting Engineering Solid Mechanics 3 2015 195-206 Contents lists available at GrowingScience Engineering Solid Mechanics homepage esm The influence of cutting conditions and cutting tool geometry on the atomistic modeling of precision cutting Angelos P.

The models 3 April 2015 Keywords presented are taking into account the cubic lattice of copper test two different potential Molecular dynamics functions and at the same time control the computational cost by introducing small models at Simulation realistic cutting conditions. This is realized by a novel code developed and allows focusing on Nano-machining the influence of several processes and modeling parameters on the outcome of the simulations. Cutting forces Models with and without thermostat atoms are investigated and the influence of cutting Morse potential conditions and cutting tool geometry on chip morphology cutting forces and cutting temperatures are studied. 2015 Growing Science Ltd.
