Analysis of tool wear in cryogenic machining of additive manufactured Ti6Al4V alloy

The obtained results demonstrate that the higher cutting speed and feed rate the higher the tool wear; nevertheless, it was found the cryogenic cooling allowed reducing the adhesive wear mechanism of the workpiece material on the tool cutting surfaces in comparison with dry cutting, proving the feasibility of utilizing the cryogenic cooling to reduce the tool wear when machining the EBM Ti6Al4V.
