摘要：
The invention relates to a method for cutting a preform (1) intended for the production of a turbomachine part and comprising a weaving of a plurality of threads (9), said threads (9) comprising singles (3) that are visually identifiable, along a cutting contour (5) calculated based on a preform model in which the threads (9) have a reference arrangement, said method including the steps consisting of: - taking an image of the preform (1), - processing the image in such a way as to determine a deviation in the arrangement of the threads (3) which are visually identifiable relative to the reference layout, - correcting the cutting contour (5) according to said deviation, and - cutting the preform along the corrected cutting contour (13).
