The present experimental research on drilling studies the process parameters that are affecting the machining
performance of CNC Drilling. 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 Spindle Speed and Feed Rate, which are optimized for
minimum Delamination Factor and minimum Surface Roughness during drilling of Aluminium 6061. Analysis of Variance is
also used to find out variable affecting the various responses mentioned above.
