An Analyse of Optimum Parameter on Cutting Force and Surface Roughness by TAGUCHI Method during Turning on EN9 (Hard Steel)

In present area of advance technology, the qualitative and quantitative requirement of customer is frequently change so the demand of the hour is increasing. Maintaining the economic production with optimal use of resources is of prime concern for the engineers. Metal machining is one of them. Metal machining with various process parameters is one of them. The experimental and theoretical studies show that process performance can be improved considerably by proper selection of machining parameters. The challenge of modern machining industries is mainly focused on the achievement of high quality, in terms of work piece dimensional accuracy, lower surface roughness, high production rate, less tool wear on the cutting tools, economy of machining in terms of cost saving and increase the performance of the product with reduced environmental impact.This particular phenomenon can affect the efficiency and quality of the process. The performance was assessed in terms of different parameters such as depth of cut, material removal rate, cutting efficiency. Experimental investigations were conducted to study the effect of different cutting speed , feed rate and depth of cut on material removal rate (MRR) and surface roughness in CNC machine. Taguchi's design of experiments and analysis of variance were used to determine the effect of machining parameters on Ra and MRR.
