Response surfacemethodology (RSM) is empirical statistical tools
that are being used for modeling and analyzing problems where the
response is influenced by several independent variables and the aim
is to get an optimum response. Thismethodology is widely used
in chemical engineering and applied sciences to optimize process
variables. As described RSM usually contain three steps: (a) design
and experiments, (b) response surface modeling through regression,
(c) optimization. In this study, this technique was employed to
assess the main and interactive effects of the parameters and also to
model and minimize the wear of the steel balls.
