Influence of Carbon Coatings on Tungsten Carbide Tool Inserts

The most popular and often used high production tool materials nowadays are tungsten carbides. The acceleration of enhanced cutting tools with respect to the achievement of a superior tribological attainment and wear-resistance is the productivity increase of manufacturing processes. This led to the creation of hard coatings for cutting instruments, which are thin films with one to hundreds of layers. By reducing the rate at which cutting tools wear out, these hard coatings have been shown to up the tool life by a factor of up to 10. As a result of the longer tool life, tool changes can be made less frequently, allowing for larger batch sizes to be produced, which lowers setup costs and setup time in addition to manufacturing costs.Tools made of coated tungsten carbide (WC) are the best to use when machining tough, challenging metals in the manufacturing sector. While creating a superior surface finish during machining, these tools provide good resistance to wear and friction. Additionally, these WC machines have a proven track record of productivity in creating lots of parts.In the present work ANOVA software is used to estimate the parameters which influence the tool life and surface roughness.The input parameters were Spindle speed (450, 710, 1800 rpm), Feed rate (0.05, 0.063, 0.1 mm/rev), Depth of cut (0.5, 1.0, 1.5 mm) and the response variables were the Surface roughness and tool wear and the effect of Speed, Feed and Depth of Cut on surface finish of Work Piece is studied for the machined surface.
