  • Automated system and method to manufacture aeronautic junction parts
    Patent number: 10324426
    Abstract: Every junction part for an airplane wing is manufactured with overmaterial. Each part is measured with a laser based interferometer or other scanning technique and the “as built” measurements are compared with a model to generate a new trajectory milling program to fill or prevent gaps between parts using a points cloud and B-Spline algorithm to generate a new surface to be milled. Once the program is generated (new trajectories) and post processed, it is sent to a milling machine to perform overmaterial milling on already milled parts with overmaterial. This technique can be used to eliminate gaps between junction parts and the corresponding need for shims.
