Abstract Aiming at milling TC17 titanium alloy materials with carbide ball-end mill, effects of different ball-end cutter structural parameters on surface roughness, surface morphology, residual stress and micro-organizations are studied. The results show that when the rake γ 0=8°, fl ank α 0 =12° and helix angle β=35°, the best surface integrity for test pieces can be obtained. The surface roughness is about 0.40μm, the residual compressive stress in x direction is 324MPa, the residual compressive stress in y direction is 218MPa. And surface integrity doesn’t obriously change.
