Titanium alloys are excellent materials, but typical processing resistant materials. Laser forming is expected as new method of metal sheet forming, especially shape tuning. Laser forming can bend the Titanium sheets without the brittle cracks. The bended angle at free edge was different from the angle at center part, even if same laser processing conditions were applied. This research simulated deformation behavior at the free edge to investigate the influence of the free edge. It was confirmed that the ratio of the irradiated energy to the heat capacity of a free edge related to the bended angle.
