Effects of cutting conditions on the milling process of titanium alloy Ti6Al4V

Titanium alloy is a difficult-to-cut material, widely used due to its excellent material and mechanical properties. In this paper, the cutting mechanisms of titanium alloy Ti6Al4V under up-milling and down-milling with different cutting conditions have been theoretically and experimentally discussed. The milling processes were simulated by an orthogonal cutting finite element model. And a series of milling experiments were carried out to verify the simulated results. Significantly, it elaborates the prominent differences of cutting mechanisms of titanium alloy between up-milling and down-milling.
