Abstract: The present invention relates to a method for obtaining a solid blade of a turbomachine, comprising a core, a tip and a root, the method comprising: —a step of producing a blank from at least two parts (50, 51), at least one of which is a solid part, the at least two parts being assembled by a diffusions connection technique and without melting, and—a step of machining this blank in order to produce a blade with a defined profile.

Abstract: The invention relates to a device, a method and an assembly of parts produced by cutting in a block B of metal or composite material, following a determined trajectory. The device comprises a guide (3) forming said trajectory and a support (chain 9) mounted in the guide in a sliding manner, comprising a lateral blank (23) provided with at least one cutting plate (24) comprising a protruding cutting edge (25) arranged so as to carry out the cutting in a normal direction (26) in relation to the blank.

Abstract: The present invention concerns a method for sharpening a worn removable machining tip (3) and the corresponding sharpened tip. The tip having a first cutting edge (7) damaged after a first use (u1), said tip having, in the state prior to the use of same, specific dimensional and geometrical parameters within a defined tolerance range and said first undamaged cutting edge (7) having a defined sharpness, the method involves sharpening the cutting face (9) by removing material from said cutting face on said first damaged edge (7), in order to make said tip (3) match said specific dimensional and geometrical parameters within said defined tolerance range, having a second cutting edge (7?) of said defined sharpness.

Abstract: The present invention relates to a set (1) of plates (2, 3; 12, 13; 21, 22; 41) or parts obtained by cutting a block (4, 4?, 4??, 35) of metal or composite material extending around a plane (5) comprising a first plate (2, 12, 21, 41) or part having an upper face (7, 33) and is second plate (3, 13, 22) or part having a lower face (8). The upper face (7, 33) of the first plate (2, 12, 21, 41) or part has a surface (7, 330) having at least two lines of inflection or changing slope with respect to said plane (5), and the lower face (8) of the second plate (3, 13, 22) or part has a surface (8) with a shape complementary to the upper face (7, 33) of the opposite first plate (2, 12, 21, 41) at a more or less constant height, corresponding to the height of the cutting line (34) in the block (4,35).

Abstract: A method and device for manufacturing turbine blades (5; 7; 28; 33) made of a metal alloy. Starting with aluminum and titanium alloy bar (10; 34) having a simple and/or axisymmetric shape, at least two mutually interlocking blanks (2; 3; 4; 8; 11) are produced in the bar (10; 34) by waterjet cutting (16) and then each one of the blanks (2; 3; 4; 8; 11) thus obtained is machined separately in order to obtain the blades (5; 7; 28; 33) having a final profile.

Abstract: A manufacturing line for manufacturing a print belt comprising a support-forming strip and a photopolymerized resin forming printing characters, the line comprises spreader means adapted to spread the resin on the strip, photopolymerizer means adapted to solidify that portion of the resin that is to correspond to the printing characters, remover means adapted to remove the non-photopolymerized resin from the strip, and drive means adapted to drive the strip in translation in such a manner that each of its transverse sections passes in succession in register with the spreader means, the photopolymerizer means, and the remover means.
