An Investigation for CNC Turning Parameters for Machining EN-24

Abstract

The present experimental research on Plain turning studies the process parameters that are affecting the machining performance and productivity of Plain Turning. A combined approach is used for the optimization of parameters and performance characteristics based on Taguchi method. The design of experiments is based on Taguchi's L9 orthogonal array. The response table and response graph for each level of machining parameters are obtained from Taguchi method to select the optimal levels of machining parameters. In the present work, the machining parameters are Speed, Feed Rate and Depth of Cut, which are optimized for maximum material removal rate (MRR) and minimum Surface Roughness during turning of EN-24. Analysis of Variance is also used to find out variable affecting the various responses mentioned above. The cutting speed and depth of cut were found to be the major dominating factors for MRR and surface roughness. Feed was found to be least influencing parameter for both MRR and Surface Roughness.
