The delamination in drilling of GFRP composites has been analyzed using
Taguchi’s method and multiple regression analysis. It has been established that feed
rate and drill diameter are the most inuential parameters affecting drilling-induced
damage, and the models developed with these techniques are suitable for predict-
ing and optimizing the delamination factor (Lat ha et al. 2011). The microgenetic
algorithm technique, a multiobjective optimization that is based on the a posteriori
approach, can be used to optimize the drilling process. The proposed optimiza-
tion technique increases the exibility ...
