Abstract

The present work is associated with End milling of En-19 steel. The paper represents the influences of different cutting parameters like cutting speed feed and depth of cuts on surface roughness of the En-19 steel. The Taguchi method has been applied to optimize the machining performance in terms of surface quality of the product, with EN 19 grade steel of cross section 50mm×32mm×19 mm as the work piece. Tin-coated carbide cutting tool having four flute 12mm diameter, shank length 30mm and cutter length 35mm is used for experiment on a vertical milling machine . Taguchi's L9 orthogonal array is employed for the experimentation. The factors considered for experimentation and analysis were cutting speed, feed rate and depth of cut. Analysis of variance (ANOVA) was employed to analyse the effect of these milling parameters. The analysis results revealed that the depth of cut was the dominant factor affecting surface roughness. Confirmation test results showed that the Taguchi method was very successful in the optimization of machining parameters for minimum surface roughness.
