چکیده:
Since, experimentally investigation of machining processes is difficult and costly, the problem becomes more difficult if the aim is simultaneously optimization of themachining outputs. This paper presents a novel hybrid method based on the Artificial Neural networks (ANNs), Multi-ObjectiveOptimization (MOO) and Finite Element Method (FEM) forevaluation of thermo-mechanical loads during turning process. After calibrating controllable parameters of simulation bycomparison between FE results and experimental results of literature, the results of FE simulation were employed fortraining neural networks by Genetic algorithm. Finally, the functions implemented by neural networks were considered as objective functions of Non-Dominated Genetic Algorithm (NSGAII) and optimal non-dominated solution set were determined at the different states of thermo-mechanical loads. Comparisonbetween obtained results of NSGA-II and predicted results of FE simulation showed that, developed hybrid technique of FEMANN-MOO in this study provides a robust framework for manufacturing processes.
