Research on Automatic Correction of Cavity Distortion for Laser Double Beam Coupled Machining

In this paper, the process of high-energy laser processing of metal materials, the overlap degree of dual-beam laser make the effect of distortion of work piece in the parts is study. Aiming at the law of low overlap degree of light beam, large distortion of machined holes, higher overlap degree of light beam, better shape accuracy of machined holes. In order to improve the accuracy of work piece hole processing and reduce the influence of hole distortion on work piece accuracy, an automatic adjusting device is designed to detect dual-beam light and adjust the control system to make the overlap of double-spot higher, so as to ensure that the hole of work piece meets the required quality requirements. The results show that the design meets the desired accuracy and requirements.
