Summary: | The invention belongs to the field of precise and efficient processing of a micro part, and particularly relates to a cutting process simulation-based single-crystal copper micro-milling force forecast method. The cutting process simulation-based single-crystal copper micro-milling force forecast method comprises the steps of initially and comprehensively considering influence of factors such as crystal deformation kinematics, a crystal plasticity constitutive relation and hardening law of rate-dependent crystal on single-crystal copper micro-milling due to the specialty of a single-crystal copper material; secondly, deducing an incremental form of a constitutive equation, writing single-crystal copper VUMAT user material sub-program by employing a Fortran language, and introducing crystalplasticity constitution into a finite element simulation; and finally, performing simulation modeling on the single-crystal copper micro-milling process by ABAQUS software to achieve single-crystal copper micro-milling force |
