Abstract
In this work, the effects of process parameters such as laser output power, beam diameter and scan speed and also sheet thickness on the bending angle have been numerically investigated in the laser bending process. For this purpose, Abaqus software is used for investigating the effect of various process and sheet parameters on the bending angle. The results show that with increasing the laser output power, bending angle is increased. Also, the bending angle is decreased with increasing the beam diameter, scan speed and sheet thickness.

Summary
Laser bending has emerged as a new and very promising technique to form sheet metal by thermal residual stresses. In 2013, Safari et al [8] in a novel work studied the effect of process parameters on bending angle in the laser bending of tailor machined blanks. Laser output power, beam diameter, number of radiation passes, and start point of scan path have the most important effects on bending angle, respectively They concluded that selecting a suitable irradiating method can noticeably improve the bending angle in the laser bending of tailor machined blanks. In this work the effects of process parameters such as laser output power, beam diameter and scan speed and sheet thickness on the bending angle have been investigated numerically in the laser bending process. The bending angle is decreased with increasing the beam diameter, scan speed, thickness and inertia moment
