Multiple surface roughness characteristics optimization in CNC end milling of aluminium using PCA [Elektronski vir]
Nair, Anish ; Govindan, P.
The present study highlights a multi objective optimization problem by applying the Principal components analysis method coupled with the Taguchi method through a study of CNC end milling of 6061-T4 ...Aluminium. The study is aimed at evaluating the best process parameters which could simultaneously provide multiple requirements of surface quality. In the present work individual response correlations have been eliminated first by means of Principal components Analysis (PCA). Principal components are found out which are independent quality indices. The principal component having the highest accountability proportion is considered as the objective function. Finally the taguchi method has been used to solve this objective function. In the current paper two surface roughness parameters have been taken into consideration.
