Material properties and machining behavior of AlCuNiTiZr with molecular dynamic simulation

Abstract The material cutting mechanism was investigated under the impact of the ratio of amplitude, temperature, phase angle, and the vibration frequency to mechanical attributes of AlCuNiTiZr high-entropy alloy materials investigated during the multi-dimensional vibration cutting (MDVC) has been studied with the help of molecular dynamics models. This study aims to clarify the influence of factors affecting the material’s internal structure during cutting. As the shear amplitude and frequency increase, the average total force decreases. However, when considering MDVC, variations in phase angle have minimal impact on the average total force. The chip atom count further confirms that MDVC enhances the machined surface quality, particularly at higher vibration frequencies, smaller amplitude ratios, and optimized phase angles.
