Abstract

In this study, Laser Forming of steel was investigated in order to create V-Shape bend. The result shows, Increases in laser power within the temperature gradient range, lead to higher Bending Angle. Scan velocity, beam diameter, and thickness of the sheet metal were known as effective factors on Bending Angle. Increases in value of mentioned parameters caused lower Bending Angle. Also, the beam diameter is the most effective parameter in determination of the Bending Angle to form A-131 steel into V shape product. In addition to main factors, the interaction effect of power-thickness, scan velocity-thickness, beam diameter-thickness, and scan velocity-beam diameter were considered as effective parameters in forming of A-131 by using laser beam. Also, maximum difference between result of FE model and regression equation was 6. 5 %. This indicates the appropriate accuracy of the proposed model. Also in this study, a new method was developed based on the Entropy generation for prediction of the increasing and decreasing trend of Bending Angle. According to the result, Entropy generation method is capable to predict the effect of laser power, beam diameter, and scan velocity.
