Investigation on Tool Life and Resultant Force During Turning of Hardened EN24 Steel Using Multilayer Coated Carbide Tool

Among users, demands for extremely tough, long-lasting, strong steel components are increasing. To meet these demands, manufacturers are constantly striving to develop cutting-edge technologies and materials that can withstand the extreme conditions of machining. Additionally, the use of advanced coatings and coating technologies has become crucial in enhancing the performance and lifespan of cutting tools in such demanding applications. With this view, this study investigates the tool life and resultant force during turning EN24 steel (35 HRC) using a multilayer coated tool. This study found a smaller feed = 0.17 mm/rev, a lesser depth of cut = 0.61 mm, and a cutting speed of 184.95 m/min produced a lower force, better tool life, and a rate of material removal. Within the range of the chosen parameters, the created models' correlation coefficients, which were found to be close to 0.9, suggest that they might be used with confidence to predict the responses for the specified tool and work material combination.
