Abstract
Laser bending is a process of deforming metal worksheets using thermal stressed generated due to controlled laser heating of work material. It can produce precise bend angle in the worksheet. This chapter presents 3D nonlinear transient thermomechanical numerical modeling and simulation of forced air cooling of laser bending process. Simulations have been carried out by using finite element method (FEM). Parametric study on the variation of important process parameters, viz., laser power, scan speed, number of scans on the stress–strain distribution, temperature distribution, bend angle and edge effect is studied. The results of forced cooling are compared with those of natural cooling. The results showed a significant improvement in the performance of multi-scan laser bending process with the application of forced cooling.
