Abstract
TC21 is a new type of titanium alloy that is difficult to cut. In this research, a series of orthogonal turning tests are performed to investigate the cutting mechanisms of TC21. The effects of tool geometrical parameters and cutting conditions on turning force are analyzed in detail. In addition, the orthogonal turning process of TC21 alloy is simulated using a presented three-dimensional finite element model (FEM). The results proved that tool geometrical parameters and cutting conditions have a great effect on the turning force. Further, the results of simulation agreed well with those of the experiments, and the FEM can be used to reveal the high-speed machining behavior of TC21 alloy.
