Abstract
The phenomenon of edge effects in the laser bending process influences the accuracy of the bending metal sheet and limits the applications of laser bending in the field of high precision. In this paper, the experimental study of effects of the laser power, beam diameter, and scanning velocity on edge effects using Taguchi method is carried out. The results show that the most significant processing parameter on edge effects is beam diameter, and the combination of the laser power and scanning velocity has the greatest interaction effect on edge effects. A regression equation is obtained to predict the relative bending angle variation by the regression analysis, and of the processing parameters in laser bending can be optimized.
