摘要：The present study aims to investigate the tool wear mechanism of TiAlN-/NbN-coated tungsten carbide insert during end milling of hard Ti alloy under cryogenic treatment at 24h and 48h. The output responses are examined by looking at the flank wear, tool wear mechanism, elemental composition analysis, cutting force and vibration acceleration signal. A 12-23% and 4-11% reduction in the flank wear was noted at 48-h and 24-h cryogenically treated inserts (CTI) when compared with untreated insert. The reduction in the cutting force and vibration was also observed in the CTI when compared with untreated insert. The results showed better machinability and enhanced tool life for CTI, which is better than untreated insert under the same set of working conditions.
