| description.abstract | The present work attempts to overcome underlying
assumptions in traditional Taguchi based optimization techniques highlighted in literature. Taguchi method alone fails to solve multi-response optimization problems. In order to
overcome this limitation, exploration of grey relation theory,desirability function approach, utility theory etc. have been found amply applied in literature in combination with Taguchi
method. But aforesaid approaches relies on the assumption that individual response features are uncorrelated i.e. independent of each other which are really impossible to happen in practice. The study takes into account this response correlation and proposes an integrated methodology in a case
study on optimization of multiple bead geometry parameters of
submerged arc weldment. Weighted Principal Component
Analysis (WPCA) has been applied to eliminate response
correlation and to convert correlated responses into equal or
less number of uncorrelated quality indices called principal
components. Based on individual principal components a
Multi-response Performance Index (MPI) has been introduced
to derive an equivalent single objective function which has
been optimized (maximized) using Taguchi method.
Experiments have been conducted based on Taguchi’s L25
Orthogonal Array design with combinations of process control
parameters: voltage, wire feed, welding speed and electrode
stick-out. Different bead geometry parameters: bead width,
bead height, penetration depth and HAZ dimensions have been
optimized. Optimal result has been verified by confirmatory
test. The study highlights effectiveness of the proposed method
for solving multi-objective optimization of submerged arc
weld. | en |
