Reinforcement of Tungsten Carbide Cutting Tool Properties via Cryogenic Treatment and Process Optimization

The cutting tool performance is gradually increased and its tooling cost is through cryogenic treatment.More than 50% of cutting tool is improved by this process.Particularly the cross section and microstructure of the cutting tool is developed through cryogenic treatment.The substance properties of the cutting tool are improved by cryogenic treatment at deep freezing level.The hardness, strength and wear resistance of the cutting tool is enhanced.In this paper deals with the performance improvement such as surface finish, tool life and hardness of the tungsten carbide tool through cryogenic treatment.The process factor optimization was carried out by taguchi method.
