Abstract
The present study focused on selecting optimal factors combination that causes maximum bending angle in laser bending of AA6061T6 For this purpose a L 25 Taguchi orthogonal design four factorsfive levels is used to design experiments Here the process main factors are laser power spot diameter pulse duration and scanning speed and the main response was bending angle To correlate relationship between process factors and bending angle a radial basis function neural network RBFNN was utilized Then the developed RBFNN model was used as an objective function for maximizing deformation through teaching–learningbased optimization algorithm Results indicated that the laser power of 36 kW spot diameter of 2 mm pulse duration of 09 ms and scanning speed of 2 mm/s lead to maximal bending angle about 287circ Hereafter the optimal results have been verified by confirmatory experiments
