GPU-accelerated meshfree simulations for parameter identification of a friction model in metal machining

Đang chuẩn bị nút TẢI XUỐNG, xin hãy chờ

Results of the present investigation demonstrate that: (1) friction modeling at the tool-chip interface has a remarkable influence on the numerical simulations of machining; (2) reliability of the friction parameters is substantially interrelated with the choice and reliability of the constitutive model parameters. As a result of this work, the error of force prediction in meshfree cutting simulations can be significantly reduced by adopting an enhanced friction model. |
