چکیده
|
Laser bending is an advanced process in sheet metal forming in which a laser heat source is usedto shape the metal sheet. in this paper, temperature distribution in a mild steel sheet metal isinvestigated numerically and experimentally. laser heat source is applied through curved paths insquare sheet metal parts. finite element (fe) simulation is performed with the abaqus/caestandard software package. material property of aisi 1010 is used in fe model and experiments.the aim of this study is to identify the response related to deformation and characterize the effectof laser power with respect to the bending angle for a square sheet part. an experimental setupincluding a nd:yag laser model iql-10 with maximum mean laser power of 500 w is used forthe experiments to verify fe analysis results. it is observed that numerical results are relatively ingood agreement with the experimental results. results also show that increasing laser powerincreases the bending angle
