Abstract: A method for cutting a preform usable for production of a turbomachine part and including a weaving of a plurality of threads, the threads including single threads that are visually identifiable, along a cutting contour calculated based on a preform model in which the threads have a reference arrangement, the method including: taking an image of the preform; processing the image to determine a deviation in an arrangement of the threads which are visually identifiable relative to the reference layout; correcting the cutting contour according to the deviation; and cutting the preform along the corrected cutting contour.

Abstract: An automated method for the non-destructive testing of a woven preform for the manufacture of a turbine engine part and including a plurality of first marker threads intertwined with second marker threads, the first and second threads having light-reflecting properties that are different from those of the threads of the preform and being woven with the threads of the preform so as to form a surface grid on a given area of the preform. The method includes determining, with a plurality of consecutive steps, the spatial coordinates of the intersections between the first and second marker threads.
