Numerical Investigation of the Effect of Process and Sheet Parameters on Bending Angle in the Laser Bending Process
Author(s) Mehdi Safari*
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.
