Abstract: Orthogonal turning-milling experiments toward S30T tools machining on TC4 titanium alloy under dry cutting conditions with 100-250m/min cutting speeds were performed with Mazak Integrex 200Y machining center. The results indicated that BUE(build-up edge) and crater wear occured, as well as coating wear and delamination on the rake face after dry cutting. On the flank face, tips, groove and tipping were observed. The main causes of the tool wear were adhesion wear, oxidation wear and delamination of coating.X-ray photoelectron spectroscopy (XPS) observation showed that a lot of oxides, such as TiO2,Al2O3,CoO etc were generated in the oxidation.

Key words: coated cemented carbide, orthogonal turning-milling, wear mechanism, X-ray photoelectron spectroscopy
