Abstract

As one new type alloy, titanium alloy TC21 is difficult to cut. To investigate the machinability, the oblique cutting process for TC21 alloy has been investigated deeply. In the study, one 3D finite element model (FEM) of oblique cutting was presented to simulate the oblique turning process of TC21 alloy. In the oblique cutting simulation of TC21 alloy, Johnson-Cook material law has been adopted. Through the simulation, stress, and temperature, residual stress distribution and cutting force in the oblique cutting of TC21 alloy was obtained. At the same time, the effect of tool angle on the cutting force and residual stress in the oblique cutting of TC21 alloy has been analyzed detailedly. In addition, the simulation results have been verified by the oblique cutting tests and the residual stress tests.
