摘要：

Shear angle is an important parameter to study cutting deformation. This paper uses orthogonal cutting force test to obtain the tangential force and normal force in order to investigate the average friction coefficient on the rake face in machining super alloy GH4169. With high temperature Split-Hopkinson pressure bar (SHPB) compression test, the constitutive equation for GH4169 was established and provided material model for Third Wave Advant Edge software in order to improve the simulation precision. Comparing simulated and calculated results, it is shown that the calculated results are bigger than the simulated ones. Finally, by modifying the shear angle model, we obtain a new model, as well as simulation for its validation. The new shear angle model proves out more suitable to express the shear angle in the cutting process of super alloy GH4169.
