The objective of this study is to develop a framework of modelling the comp
lex grinding processes and finding optimal process conditions to meet the g
eneral class of process requirements. In order to achieve the above goal, n
ovel modelling schemes and optimization methods based on evolutionary algor
ithms (EA) are developed. The optimization problem of grinding processes ca
n be formulated as a constrained non-linear programming problem with mixed-
discrete variables. The adaptive least-squares (ALS) algorithm proposed by
Lee and Shin's 1998 study is extended for modelling multi-input-multi-outpu
t (MIMO) complex grinding processes using fuzzy basis function networks (FB
FN), while the modified evolution strategies (ES) is proposed for successfu
l optimization of grinding processes. Two grinding optimization problems de
monstrate the superior performance of the proposed scheme.
