The present experimental approach on turning studies the process parameters that are affecting the machining
performance and productivity of Plain Turning. 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 Heat
Treated Steel (EN-9).
