Experimental Studies on Deep Cryo Treated Plus Tempered Tungsten Carbide Inserts in Turning Operation

Improving the tool life will increase the production by reducing the tool change time and tool cost. Various surface modification techniques are available such as commercial coatings method, cryogenic treatment, nitriding and cyaniding. The
cryogenic treatment of the cutting tools enhances the micro-structural properties of the tool and used in increasing the tool life. In the present work, cryogenic treated tungsten carbide tool is used to examine the machinability characteristics on low�carbon AISI 1020 steel for turning operation. The experimental study on machining operations is conducted by Taguchi’s L9 orthogonal array for three levels with three
factors. The governing parameters of cutting velocity, feed rate and depth of cut on tool wear rate and surface finish on the machined surface. The effect of each parameter on output response is verified through ANOVA. In that, the depth of cut
is the most significant factor compared to other factors. The optimum machining condition is predicted through grey relational analysis.
