ABSTRACT
γ-titanium aluminide alloy has advantages of high temperature resistance, high performance of anti-oxidation effect, low-density, high specific strength and rigidity etc. This material is suitable to be applied in aeronautics, astronautics and automobile industry. However its high hardness, brittleness and mechanical strength bring great difficulty in machining which is particularly outstanding in deep hole drilling. This article has analyzed the cutting performance and the machinability of γ-titanium aluminide and designed a deep-hole drill with three different tool materials. The experimental result shows: (1) YG8 cemented carbide is the appropriate tool material for drilling γ-titanium aluminide, (2) Small rake angle of external edge (γo = -1°) and big clearance angle of external edge (αo = 10~12°) should be chosen and (3) Best wear results are obtained when oil is utilized as cutting fluid.
