Notes:
The nickel-based superalloy GH4169 is a typical difficult-to-cut material, but it has beenused in a good many kinds of aeronautical key structures because of its high yield stress andanti-fatigue performance at the temperature below 650°C. In this paper, finite element method(FEM) was introduced to study the saw-tooth chip forming process in detail when machiningnickel-based superalloy GH4169. By the way of Lagrangian visco-elastic plastic approach,adiabatic shear band (ASB) was simulated in high speed machining condition by generalcommercial finite element code, and the mechanism of the adiabatic shearing phenomenon atprimary shear zone was analyzed with the help of finite element analysis (FEA). Thecomprehensive comparisons of saw-tooth chip morphology under a wide range of cutting speedwere also presented
