| چکیده | ||
| In this work, the laser bending process of perforated tubes is investigated using numerical simulations. For this purpose, the finite element software ABAQUS is used. The effects of key process parameters such as laser output power (LOP) and laser scanning speed (LSS) on the main displacement of the free edge (desired response) and the lateral displacement of the free edge, cross-section ovality, ovality of holes located along the laser irradiating path, and thickness variations in the tube wall (undesired responses) are investigated. The results show that the main displacement of the free edge of the laser-bent tube increases with an increase in the LOP and a decrease in the LSS. Similarly, the lateral displacement of the free edge of the laser-bent tube increases with an increase in the LOP and a decrease in the LSS. Other undesired effects, including cross-section ovality, ovality of the holes located at the laser irradiating path, and thickness variations in the tube wall, also increase with an increase in the LOP and a decrease in the LSS. | ||
