experimental analysis, statistical modeling and optimization of the edge effects associated with laser-bent perforated sheets

The edge effect phenomenon is instrumental in influencing the precision, reliability, and overall caliber of laser laser-bent sheets. this study conducts an experimental investigation into the edge effect present in laser laser-bent perforated sheets. to this end, the impact of critical input parameters in the laser bending process, including laser output power, laser scanning speed, and the number of irradiations on the edge effect of laser laser-bent perforated sheets, is meticulously assessed. the findings indicate that the edge effect phenomenon intensifies with an increase in laser power. furthermore, it is observed that the edge effect diminishes as the laser scanning speed escalates. additionally, an increase in the number of irradiations correspondingly enhances the edge effect of perforated sheets. the optimization of input parameters reveals that to attain the minimal edge effect in laser bent perforated sheets, the laser output power, scanning speed, and number of irradiations must be calibrated to 90 watts, 3 mm/s, and 10, respectively an edge effect of merely 1.25% at the free edge of the lbps can be successfully achieved.
