It has always been a critical issue to understand the material removal behavior of Vibration-Assisted Machining (VAM). especially on atomic level. To find out the effects of vibration frequency on material removal response. a three-dimensional molecular dynamics (MD) model has been established in this research to investigate the effects of scratched groove. https://www.ngetikin.com/flash-choice-1-Gallon-Roll-Cote-High-Performance-Moisture-Vapor-Barrier-Coating-and-Primer-limited-super/
