Assessment of the Effect of Titanium Nitride Coating on Ceramic Tool Insert and Estimation of Tool Life and Surface Finish While Machining SS304 Stainless Steel

Modern machining industries are primarily concerned with achieving high quality in terms of workpiece dimensional precision, surface finish, and high production rate, as well as reducing cutting tool wear, machining economy, and product performance while reducing environmental effect. To begin with, in various manufacturing industries, component quality plays a critical part in meeting technical requirements. Only machining with appropriate machine tools and machining conditions may achieve component precision and accuracy.Steels are widely employed in engineering applications such as automotive, aerospace, and other industrial uses. The tool Wear and Surface Roughness are influenced by Cutting parameters like speed, feed, and cut depth.To improve the tool life, inserts were coated with harder materials to achieve better performance. Coated tool inserts increase the tool life by increasing toughness, resistance to abrasion, resistance to thermal deformations, modulus of elasticity, and wear resistance, which results in achieving precision and accuracy in machining components. Also, these coated tool inserts broaden the range of depth of cut, cutting speed, other machining parameters and reduce the time of machining. Coating of tool Inserts gives longer tool life, higher cutting parameters leading to reliable performance while machining.The ANOVA software is used to estimate the characteristics that influence tool life and surface roughness in this study. The response variables were Surface roughness and tool wear, and the input parameters were Spindle speed (450, 710, 1800 rpm), Feed rate (0.05, 0.063, 0.1 mm/rev), and Depth of cut (0.5, 1.0, 1.5 mm). The effect of Speed, Feed, and Depth of Cut on surface finish along with tool life for Work Piece is studied for the machined surface.
