3-Dimensional Welding and Cutting Using High Power CO_2 or YAG Laser

摘要

In this paper, the theory of 3-dimensional laser welding and cutting was established firstly. Then the expert system for 3-dimensional laser processing and software of 3-dimensional laser processing CAD/CAM were developed, respectively. Under the guidance of these software, with high pwoer CO_2 laser, the 3-dimensional covers of a car have been cut and edge smoothed, which decrease the number of models and shorten the period of production. With adoption of this technology, the covers of extended Hong Qi cars and furthermore Da Hong Qi cars have been processed scucessfully, which will bring out the innovation of production design and the revolution of processing technology in manufacture industry
