AN INVESTIGATION ON THE DEFLECTION ESTIMATOR MODELS IN LASER FORMING OF THE FULL CIRCULAR PATHS

چکیده مقاله

In this paper, the linear and non-linear deflection estimator models in laser forming of full circular scan paths are studied. Firstly, regarding the Taguchi design of experiment method, some simulations are performed with the verified finite element model. The model is then studied with two groups of linear and non-linear models with different assumptions. Finally the best model type is selected by comparing the results of different models' mean error values. It is concluded that, regarding the limitation of the used models' training data, the error value of the linear model with the assumption of the independency of the models and in separated number of the scan radii is less than the other models. The difference between the mean error values of the first and second best models is about 44%.
