Efficient prediction of milling distortion using inversely-identified inherent strains

, 2023
Abstract Predictive milling distortion has been widely used to optimize milling design and process. Inherent strains method (ISM) applies plastic strains calculated from small-scale thermo-mechanical simulations to large-scale models to assess residual deformation in less time.
