Machining of Titanium and its Alloy (1st Report)

Titanium and its alloy to have excellent heat resisting and anti-corrosion properties are used for aerospace industry and many parts of chemical equipments, but they are hard to machine. Machining property of them is studied by the observation of tool failure, cutting resistance and tool life through hot-machining and normal machining. 1) Titanium alloy shows lower cutting resistance through hot-machining than normal machining, while titanium shows higher. 2) The failure of ceramics tool through hot-machining is larger than normal machining. 3) Sintered carbide (K-type), not contained TiC and TaC, is the best to machine the titanium and its alloy.
