Investigation of Optimization Machining Parameters for En19 While Using Tnmg Insert by Taguchi and Anova

Abstract

EN19 is high-quality alloy steel with good tensile strength due to a combination of good ductility and shock resistance. EN19 is suitable for applications with very high loading such as engine gearboxes, automotive gears, and parts, Shafts, Towing pins, Load bearing tie rods, and Oil & Gas industry applications. The material finds application where strength is a primary consideration. EN19 machining is a challenging task in the manufacturing industry. In this study, the TNMG Carbide insert is used for turning the EN19 material. The input parameters are taken such as spindle speed, feed rate, and depth of cut. The output parameters such as Surface roughness, MRR, and Tool Wear were measured. To achieve the optimum results in ANOVA, the Taguchi method is used. Experimentally it is observed that, during the Turning of EN19 by TNMG the MRR is maximum at speed1025r.p.m, feed 0.10 mm/rev, and depth of cut is 1.5 mm. Tool Life is maximum at a speed of 1025r.p.m, feed 0.25 mm/rev while the depth of cut is constant. Surface Roughness is minimum at speed of 455 r.p.m., feed 0.25 mm/rev, and depth of cut is 1.5 mm. The optimum parameter for EN19 is Speed at 1025 r.p.m, feed is 0.10 (mm/rev) and depth of cut is 1.0 mm for turning operation
