Experimental Study and Examination of Coated, Uncoated, and Cryogenically Treated HSS Cutting Tools

High-speed steel (HSS) tools are the most commonly used tools in small and medium-scale industry. This study report presents findings from an experimental evaluation of tungsten carbide-coated, shallowly cryogenically treated, thoroughly cryogenically treated, and untreated HSS tools. High-speed steel is utilized because it is more affordable than other cutting tools while yet providing good reliability and quality. To ensure the tool's dependability, it is crucial to further enhance its capabilities. The best course of action is to make something harder. Various heat treatment and cold treatment procedures are employed to increase high hardness and good wear resistance. Cryogenic treatment is one such widely utilized and efficient treatment method. For high-speed steel, it gives significantly greater wear resistance and hardness. To determine the hardness and corrosion resistance, experiments were run. To determine the specimen's microstructure, microstructure analysis is carried out. The machining time was calculated once turning was completed. Calculations were made for tool life, MRR, and wear volume. Tools that have been tungsten carbide coated, subjected to shallow cryogenic treatment, deep cryogenic treatment, and left untreated are compared.
