Numerical and Experimental Study of Effect of Scan Velocity in Laser Forming by Temperature Gradient Mechanism

In this paper the process of laser forming has been investigated using an analytical and an experimental method for three levels scans velocity. A coupled analysis has been performed in ANSYS®. Also in order to prove the predictive methods, experiments on thin sheet metals have been done when a laser of a fair power was used. Before done, experiments were designed with full factorial chosen as the experiment scheme planning. For performing experiments a CO2 laser a maximum power of 200 watt is used. A CMM is used to measuring the bending angle of the workspice. Finally, a statistical analysis on the experimental data was performed. The comparison between numerical and experimental results shows the bending angle decreased by increasing the scan velocity also rate of the bending angle decreased by increasing the scan velocity.
