EN-31 Steel Material, Surface Roughness, Hardness, Taguchi Method, ANOVAAbstract
In this study, project work focus on find out optimal process parameter in hot machining of EN-31 steel
material. The resultant data was analysed by taguchi method to find out a combination of optimal process parameter.
In present research work, an experimental study was conducted to investigate the influence of process parameters in
hot machining particularly spindle speed, feed rate and temperature on surface roughness and hardness. Hot
machining operation of EN-31steel using a tungsten carbide cutting tool. The heating of the work-piece was carried
out by using oxygen and LPG cylinder. Study also includes find out optimum value with the help of main effect plot
and ANOVA tables to find out which parameter affect most for surface roughness and hardness.
