| Abstract: | This article focuses on three-dimensional finite element numerical simulation in the process of the diffraction grating carving with extension pyramidal graver by using the software of DEFORM-3D. Through the analysis of the material flow velocity,equivalent stress figure and equivalent contingency figure,we mainly discuss metal flow law in the process of aluminum forming,which provides valuable reference for direction and future of the diamond knife. |
