Method and system for cutting a preform intended for the production of a turbomachine part
First Claim
1. A method for cutting, by a cutting machine, a preform usable to produce a turbomachine part and including weaving a plurality of weaving threads, the weaving threads comprising visually identifiable threads, the machine being adjusted to make a cutting of the preform according to a cutting contour, the method comprising:
- taking an image of the preform;
processing the image to identify at least one point of reference in the weaving of the preform, said point of reference corresponding to an intersection of visually identifiable threads in the preform, the cutting machine automatically correcting its position relative to the preform, from the identification of the point of reference; and
cutting the preform according to the cutting contour,wherein the method is free of manual adjusting of the preform by an operator prior to the cutting.

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.

2. A method for cutting a preform usable to produce a turbomachine part and including weaving of a plurality of weaving threads, the weaving threads including visually identifiable threads, according to a cutting contour calculated from a preform model wherein the weaving threads present a reference layout, the method comprising:
-
taking an image of the preform; processing the image to determine a deviation in a layout of the visually identifiable weaving threads relative to the reference layout; correcting the cutting contour as a function of the deviation; and cutting the preform according to the corrected cutting contour, wherein the method is free of manual adjusting of the preform by an operator prior to the cutting. - View Dependent Claims (3, 4, 5, 6, 7, 8)
