Experimental investigation on the machinability of Ti2AlNb intermetallic alloy
Ti2AlNb intermetallic alloy is a newly developed high-temperature resistant structural material due to its excellent material and mechanical properties
which also make it to be one of the most difficult-to-cut materials. In order to investigate the machinability of Ti2AlNb alloy
a series of turning experiments of Ti2AlNb alloy with varying cutting speed and feed rate using coated carbide tools were carried out. The results associated with cutting forces
cutting temperature and tool wear are presented and discussed. Moreover
the cutting performance of Ti2AlNb alloy is evaluated in comparison with that of most commonly used Ti6Al4V and Inconel 718 alloy in terms of the cutting forces and cutting temperature. Considering material removal rate and tool life
the optimized machining parameters (cutting speed v=40-50m/min
feed rate f=0.08-0.1mm/rev)for cutting Ti2AlNb alloys using coated carbide tools are recommended.
