Evaluation of Material Removal Rate and Surface Roughness in Turning Using Response Surface Methodology

The Quality and productivity plays a significant role in today's manufacturing market. Therefore, every manufacturing or production unit concerns about the quality of the product. Apart from quality, there exists another criterion, called productivity which is directly related to the profit level and also goodwill of the organization. This invites optimization technique which seeks identification of the best process condition or parametric combination for the said manufacturing process. In order to tackle multi-objective optimization problems, the authors have made an attempt to present Full Factorial Method in straight turning of Mild Steel bar using HSS tool. Experiments were conducted in a series of tests called runs, in which changes are made in the input variables in order to identify the reasons for changes in the output response using Response Surface Methodology (RSM). The predicted optimal setting ensured the minimization of Surface Roughness and maximization of Material Removal Rate (MRR).
