Abstract: The invention relates to implement the sealing, porosity and sweeping functions, combined. For this purpose, the present invention proposes to confine the waste and to suction the waste at the ejection head by means of a sufficiently flexible connection, such as to remain in contact with the machining area. According to an embodiment, a portable machining machine (1) operated by a pressurized jet (112) includes a waste recovery system (5), an injection head (11) which is provided with a nozzle (111) having an axis (A1) that is substantially perpendicular to the surface to be machined (4a) and which is driven by a digitally controlled two-axle guide system, the ejection head (11) being extended by an enclosure (12) to the surface area to be machined (4a). In addition, the enclosure (12) comprises a tubular portion (121) consisting of two walls (12a, 12b) which slide coaxially along the axis (A1) and a double-pivot articulation device (123).

Abstract: The invention relates to machine a component made of composite material in order to eliminate singularities, defects or damage to the component using a method that is repeatable and adaptable. To do this, it is proposed that the defects and their type be identified by image processing of the surface of the component and that the local machining rates at which the plies are machined be regulated at the function of this identification. According to one embodiment, a system (10) for the ply-by-ply machining of defects of a component made of composite material includes a numerical data processing unit (1) combined with a sweep control (2) that commands the sweep of a high-pressure water jet machine (20), and an image formation assembly (3) including an image capturing device (30, 31) connected with the numerical processing unit (1).

Abstract: The invention relates to a gun for spraying liquid at a very high pressure, referred to as a focusing gun, and to a method for manufacturing same, according to which two elongate parts (2) are manufactured to be assembled so as to form the focusing gun. Each of said parts includes an assembly surface (J) comprising a central groove (3) for forming the duct of the focusing gun once the parts have been assembled, and a gluing tank (9) for being filled with an adhesive substance. Further, at least one of said parts (2) has a centering rib (6), projecting relative to the assembly surface thereof, while the other part has, for each centering rib (6), a centering cavity (7), the size of which is suitable for tightly housing said centering rib.

Abstract: The invention relates to a method for repairing a wall (1), including a plurality of layers (2), each layer including fibers (3) extending in a main direction (4), and having a damaged area (5) over a plurality layers (2). The repair method includes a material removal step comprising making a recessed area (6) encircling the damaged area (5) and comprising a peripheral area (7) including steps (8) and adapted such that each step defines an interface area (9) having a width (10), the dimension of which in the main direction of the fibers of the lower layer adjoining the interface area (9) is greater than the dimension of said width in directions other than the main direction (4), a step of producing a replacement part (12) suitable for obstructing the recessed area, and a step of assembling the replacement part (12) onto the wall.
