J. Cent. South Univ. (2018) 25: 1107-1115 DOI: https://doi.org/10.1007/s11771-018-3810-z A model of deformation of thin-wall surface parts during milling machining process WANG Ling-yun(王凌云)1...-dimensional finite element model was established for the milling of thin-walled parts. The physical model of the milling of the part was established using the AdvantEdge FEM software as the platform......
that the particles are crushed predominantly under shearing stress in PBM process and under compressing stress in VBM process. The energy of VBM is also larger than PBM. So these two different ball milling...
