Laser forming is a non-contact processing technique for metallic materials, which has usually been used for bending metal sheets. Because laser forming does not have spring-back compared with the conventional bending method, it is usually used for high-precision bending. In the previous research, the authors have successfully used laser forming for fabricating small, thin wire parts. However, it is very difficult to precisely control the bending angles because the heat capacity of the micro-wire is very small. In this study, the target is focused on the laser forming of micro-wire, with the diameter of 0.05mm. An error compensation method based on visual feedback is proposed. As a result, the dispersion of the bending angles by this proposed method can be achieved around 0.2 degrees.
