Abstract

The Material Removal Rate (MRR) is a critical performance indicator in turning operations, directly influencing productivity, cost-efficiency, and part quality. In this study, the focus is on optimizing the process parameters to improve MRR during turning operations using carbide insert tools. Carbide inserts are favored in machining due to their high hardness, wear resistance, and ability to withstand elevated cutting forces, making them suitable for high-performance turning operations. The experimental investigation of turning on EN8 steel of grade SAE (AISI) 1040 using a carbide insert tool was the focus of this work. The following study’s main goal was to apply the Taguchi method to ascertain how the machining parameters – feed, depth of cut, and cutting speed – affect the rate at which material is removed from the machined material. Finding the ideal machining parameters to optimize the material removal rate for the chosen tool and conducting a comparison analysis for cutting tools was the goal. A Design of Expert (DOE) was used to create the experiment matrix, which consisted of nine runs. A weighing machine was used to measure the material removed during machining. This machine, which is made by SHINKO DENSHI Co. LTD. in Japan, has a 300-gram capacity with an accuracy of 0.001 grams. Its model is the DJ 300S. MINITAB ® 17 was used to compile and analyze the data. The Taguchi approach was used to model and assess the relationship between the response variables (MRR) and the machining parameters.
