Abstract


The paper deals with the milling force modelling concerning average and maximum forces for a set of four materials. The main purpose of the work is to obtain a function of three variables (cutting depth, feed per toot and cutting speed) using response surface methodology (RSM), and artificial intelligence approach (AI). A new method based on hybrid multiple regression (HMR) using RSM, and also a novel algorithm are proposed. In AI, determination of the optimal neural network of fuzzy neural network is an important aspect when we use these models for prediction. Differential genetic algorithms for variable length genotype are proposed to optimize simultaneously both structure and parameters for AI structures. A comparative study based on performance analysis is made also.
