By analyzing and discussing the particle cutting force, atomic energy, atomic displacement, lattice structure, and dislocation in the particle microcutting process under different cutting velocities, the material removal mechanism is revealed. The results show that the atomic binding energy of Fe-C alloy increases with an increase in particle cutting velocity. The cutting force of particles and atomic potential energy of the workpiece increase obviously. The accumulated strain energy and dislocation energy in the lattice increase, the lattice deformation becomes more severe, and the material is prone to plastic deformation. The atoms form atomic groups at the front of the particle and are then remove from the surface of Fe-C alloy in the form of chips.}, keywords = {molecular dynamics; Removal mechanism; particle microcutting; Fe-C alloy}, year = {2022}, eissn = {2072-666X} } @article{MTMT:32577348, title = {Deformation behaviors and inverse Hall-Petch effect in nanoindentation of silicon: An atomistic simulation study with experimental validation}, url = {https://m2.mtmt.hu/api/publication/32577348}, author = {Wang, Yachao and Minhaj, M and Wang, Xinnan and Shi, Jing}, doi = {10.1016/j.jmapro.2021.12.032}, journal-iso = {J MANUFACT PROCES}, journal = {JOURNAL OF MANUFACTURING PROCESSES}, volume = {74}, unique-id = {32577348}, issn = {1526-6125}, year = {2022}, eissn = {2212-4616}, pages = {319-331} } @article{MTMT:31793490, title = {A review on micro-milling: recent advances and future trends}, url = {https://m2.mtmt.hu/api/publication/31793490}, author = {Balázs, Barnabás Zoltán and Geier, Norbert and Takács, Márton and Davim, J.

In the last years, the field of micro- and nano-scale manufacturing attracted a lot of interest, especially in high-end industries such as the biomedical and electronics industries. In order to improve the efficiency of these processes and understand the various underlying phenomena, it is important to develop relevant theoretical models. However, methods such as the Finite Element Method (FEM), which are well-established in the macro- or micro-scale level are not appropriate for creating models of nano-scale processes, as they treat the materials as continua. For that reason, the Molecular Dynamics (MD) method is usually used for simulations of nano-metric machining processes such as nano-milling. In the present study, a MD model of nano-milling is created and an investigation regarding the effect of cutting conditions such as feed rate and cutting speed on cutting forces, temperature and subsurface damage is conducted.}, year = {2019} }
