Definitions
- the present invention relates generally to the field of manufacturing monobloc bladed disks, preferably for aircraft turbomachines.
- abrasive water jet cutting step prior to milling, makes it possible to reduce manufacturing times and costs compared to a method based solely on milling. This is explained in particular by the fact that such a manufacturing process requires about 75% removal of material from the starting block to arrive at the DAM. The removal of a large part of this material by abrasive jet cutting makes it possible to reduce the production times, and also limits the wear of the milling machines.
- the abrasive water jet cutting step consists essentially of cutting a piece of extremely complex shape, over the entire thickness of the starting block. This cutting follows a complex trajectory, called five-axis, to cut a piece of twisted or helical shape, close to the shape of an inter-blade space.
- the object of the invention is therefore to remedy at least partially the disadvantages mentioned above, relating to the embodiments of the prior art.
- the subject of the invention is a method for manufacturing a monobloc blisk, comprising a step of cutting with abrasive water jet a block of material in the general shape of a disc, made in such a manner as to remove the block material at inter-vane spaces to reveal blade preforms extending radially from a hub, said step of cutting by abrasive water jet, performed using a tooling comprising an ejection head of an abrasive water jet, comprising:
- the invention essentially makes it possible to achieve a reliable abrasive water jet cutting step, to obtain refined blade preforms, and to reduce the duration of implementation of this step of cutting by jet of water. abrasive, which obviously results in a reduction in the duration of implementation of the entire manufacturing process.
- the provision of at least one refining cut as described above, from the second face of the block of material allows to cut an area of the block previously obtained by said through cut.
- This particular zone is the one that normally undergoes the most the deflection effect of the abrasive water jet encountered during said through cut, because it is at the jet outlet.
- Said through cut can thus be made at a high cutting speed.
- the first cut can be performed in a simpler path, taking for example the form of a three-axis cut. The simplicity of the trajectory enhances the stability of the jet, and is therefore conducive to the use of a high cutting speed for this first through cut.
- each refining cut made from the second face of the block the fact that it is operated on a reduced thickness of the block increases the stability of the jet, and therefore reduces the jet deflection effect.
- the cutting speed can therefore also be high, and the precision of the cut is increased.
- one of the main advantages of the present invention lies in the fact of coming to make abrasive water jet cuts from the two faces of the block of material, which gives better accessibility. This makes it possible to obtain blade preforms as close as possible to the final dimensions, and thus to reduce subsequent milling operating times, when these are necessary. Also, it is the overall manufacturing time of the DAM which is advantageously reduced.
- this improved accessibility to cutting surfaces is not only used to refine the blade preforms obtained, but also to orient the jet in the best possible way with respect to each surface to be cut, which enhances the reliability of the process.
- abrasive water jet to obtain all the inter-blade spaces, it is successively realized:
- said relative movement between the block and the ejection head is effected by inverting the block.
- said abrasive water jet cutting step is carried out so that at least one cut piece during a refining cut escapes from the block automatically by gravity.
- the pieces concerned are intended to fall by gravity as soon as they are detached from the block, without it having to be set in motion.
- said abrasive water jet cutting step is performed so that, for at least one cut piece during a refining cut and remaining stuck in his space associated blade after cutting, said piece is split by abrasive water jet cutting into at least two sub-pieces able to escape the block automatically by gravity.
- each refinement cut is preferably a five-axis cut.
- the through cut is a three-axis cut.
- This functionality is achieved by a particular positioning of the block, preferably arranged horizontally, but especially thanks to the cylindrical nature of the piece obtained by the three-axis cut. The number of inter-blade spaces being important on a DAM, the time saving resulting from the automatic fall of these pieces is considerable.
- the simplicity of the path of the through cut reinforces the stability of the jet, and is therefore conducive to the implementation of a high cutting speed for this first through cut.
- said abrasive water jet cutting step of the block of material is carried out by in order to reveal the preforms of vanes extending radially from the hub, while retaining material forming connecting means between at least two directly consecutive vane preforms, said connecting means being spaced radially from said hub.
- this preferred embodiment is remarkable in that it provides, during the step of cutting by abrasive water jet, to reveal connecting means between at least two blade preforms, and preferably between all these paddle preforms. This makes it possible to strongly limit or even eradicate the deformations and vibrations of the blades during their manufacture, since they remain mechanically held together by the material of the initial block.
- This specificity advantageously makes it possible to apply to the various tools high feed rates, reducing the production time, without impacting the quality of the product DAM. Furthermore, the reduction of production time, as well as the reduction of blade vibrations during their manufacture, slows tool wear, in particular the wear of milling machines, which advantageously limits production costs.
- the step of cutting by abrasive water jet is carried out so that said connecting means connect together a number of blade preforms strictly greater than three, preferably directly consecutive. Nevertheless, it could be considered several sets of preforms directly consecutive connected to each other, but with unrelated sets. However, depending on the needs encountered, the number of blade preforms held together by the connecting means and the arrangement of the latter on the preforms can be adapted.
- the step of cutting by abrasive water jet is carried out so that said connecting means substantially form a ring, preferably centered on the axis of the disk.
- this ring extends over 360 °, possibly being only interrupted by the blade preforms that it connects. Nevertheless, as mentioned above, this ring may not be completely closed, namely not to connect some directly consecutive preforms.
- the step of cutting by abrasive water jet is preferably carried out so that said ring connects all the blade preforms, each intended to subsequently form a blade of the DAM.
- the step of cutting by abrasive water jet is performed so that said ring connects the heads of the blade preforms.
- the ring then forms a peripheral annular portion of the cut block, with the blade preforms extending radially inwards from this ring towards the disc.
- an alternative solution could be to provide the jet cutting step abrasive water made so that said ring interconnects said blade preforms, away from their head, radially inwardly.
- the ring connects the preforms to each other about half a length.
- the method also comprises:
- a finishing step by milling the blade blanks, so as to obtain the blades to the final profile.
- the bonding material is retained until the end of the milling finishing step, after which this material is then removed. Nevertheless, this material could be removed beforehand, without departing from the scope of the invention.
- other conventional steps can be implemented in the method according to the invention, such as:
- said monobloc blisk has a diameter greater than or equal to 800 mm.
- the connecting means holding the blades together during their manufacture makes it possible to envisage the manufacture of large diameter DAMs, with blades of great lengths, since the deformations and vibrations thereof are reduced or even eliminated.
- the vanes have a minimum length of 150 mm.
- said monobloc blisk has a disc of thickness greater than or equal to 100 mm. Nevertheless, it may have a thickness of the order of 160 mm, or even more, because of the high performance likely to be achieved by abrasive water jet cutting technique. This thickness also corresponds substantially to the distance by which each blade extends, reported along the axis of the DAM, between the leading edge and the trailing edge.
- the blades of the monobloc blisk are twisted, the twist angle can be up to 45 °, or even more.
- said block of material used is titanium or one of its alloys.
- said blisk is a monoblock blisk for aircraft turbomachines.
- said monobloc blisk is a one-piece bladed disk of a turbine rotor or aircraft turbomachine compressor.
- FIG. 1 represents a partial perspective view of a blisk for a turbomachine, capable of being obtained by implementing the manufacturing method according to the present invention
- FIGS. 2a to 2g show diagrammatic views of the abrasive water jet cutting step of the manufacturing process.
- the one-piece blisk hereinafter referred to as DAM, which is sought to be obtained by the process which is the subject of the invention, is of large dimensions, namely that it has a diameter greater than or equal to 800 mm, blades 2 of length at least equal to 150 mm, and a hub 4 of thickness "e" greater than or equal to 130 mm.
- the blades carried by the hub 4 of central axis 5 are twisted significantly, since the twist angle can reach 45 ° or more. For information purposes, this angle corresponds in a known manner to the fictitious angle between the foot 6 and the head 8 of the same blade 2.
- a block of titanium alloy material also called "raw monobloc” and preferably pre-machined, undergoes a first turning step, for example to machine this block to 1 mm of the final dimensions.
- the next step shown diagrammatically in FIGS. 2a to 2g, consists of an abrasive water jet cut of the solid block, so as to show vanes preforms separated by inter - binary spaces.
- water jet cutting at very high pressure, for example 3000 bar, and very high precision, for example six-axis. It is the very high level of pressure of the water which makes it possible to convey the abrasive while optimizing its cutting effect on the material.
- the water jet is created via a diamond or sapphire nozzle.
- a mixing chamber allows the addition of the abrasive, such as sand.
- a focusing gun homogenizes water and sand by focusing the latter on the area to be cut.
- the focusing gun 116 will be more generally referred to as the ejection head of the tooling.
- This abrasive jet cutting technique allows a high material removal rate, as well as a good repeatability. It thus proves to be entirely adapted to the removal of material aimed at creating inter-blade spaces completely crossing the thickness "e" of the block of material along its axis 5.
- FIG. 2a shows a portion of the material block 100 after the abrasive water jet cutting step has been completed.
- This block thus has blade preforms 102 extending radially from the hub 4, that is to say orthogonally to the central axis 5.
- the cut is made in the thickness of the block 100 so as to reveal inter-blade spaces 110 between blade preforms 102 directly consecutive circumferentially.
- connecting means between the preforms 102 here taking the form of a ring 112 centered on the axis 5 and preferably connecting all of the heads 108 of the blade preforms 102
- the ring 112 constitutes a peripheral annular portion of the cut block 100, and consequently creates an outer radial delimitation of the inter-blade spaces 110.
- This step of cutting by abrasive water jet is implemented by making cuts made with the ejection head 116 facing a first face 110a of the disk-shaped block, then making cuts made with the head ejection 116 facing a second face 110b of the same block, opposite the first surface 110a.
- the block 100 is held fixed, removably, on a support 111 so as to adopt a substantially horizontal position, that is to say with its axis substantially orthogonal to the ground, as shown in Figure 2b.
- the support 111 has a receptacle 113, open upwards, dedicated to the collection of cut pieces that escape automatically by gravity block 100.
- the second face 110b is pressed against the support 111.
- the block 100 is released from the support 111, returned to 180 °, then fixed again on the support 111 with the first face 110a pressed against the latter, and the second face 110b upwardly to cooperate with the ejection head 116 of the tool moving up- above the block 110.
- leading edge 115 of the blade preforms 102 is on the side of the second face 110b, while their trailing edge 117 is on the side of the first face 110a. .
- Indexing means make it possible to precisely position the block 100 on the support 111, in its two positions, for a better reliability of the process.
- a first through cut made from the first face HOa, aims to remove a first piece of material 114a extending substantially cylindrical, since resulting from a so-called three-axis cut, during which the head ejection is therefore only moved along three translation axes orthogonal to each other.
- one of the three axes constitutes the longitudinal axis of the cylindrical shape of the piece obtained 114a, which extends over the entire thickness of the block 100.
- the tooling being six-axis it makes it possible to carry out the three-axis trajectory with any inclination of the ejection head 116, which inclination is thus maintained throughout the cutting. As shown in FIG.
- the first three-axis cut is made with the ejection head of the jet 116 inclined relative to vertically, so as to be substantially oriented parallel to the desired final inter-blade space.
- the blades 2 to be obtained have been shown in plan view, with their heads in bold.
- This first cut made at a high speed made possible in particular by virtue of its simple trajectory, has a large volume, corresponding preferably between 40 and 80% of the final volume of the associated inter-blade space 110 obtained at the end of the cutting step by abrasive water jet.
- the first three-axis cutting operation aims in fact at cutting the first piece of material 114a by moving the jet ejection head along a closed line 118a passing close to the hub 4, and close to the outer radial end of the block, without reaching the latter so as to leave the material for the formation of the ring.
- the line 118a has the general shape of a rectangle, one of whose lengths closely follows the trailing edge 117 of one of the two blade preforms, and whose other length is such that the exit the jet is located at a reasonable distance from the leading edge of the other of the two blade preforms.
- this piece 114a escapes automatically by gravity of the same block. Indeed, as shown schematically in Figure 2c, under the sole effect of gravity, the piece 114a slides downwards in the direction of the ejection head 116, relative to the through orifice 119 that releases by falling . It ends its fall in the receptacle 113 judiciously positioned, and therefore requires no intervention of the operator.
- the first piece 114a takes the overall shape of a parallelogram whose two opposite sides, extending according to the thickness of the block, are respectively opposite two directly consecutive blades 2 intended to be obtained once the process is complete.
- this through cut may possibly be preceded by one or more other cuts.
- this first through cut could be of the five-axis type, and not three axes, without departing from the scope of the invention.
- the block 100 is returned to its support, to enable the realization of abrasive water jet refinishing cuts from the second face 110b.
- These cuts thus make it possible to refine the shape of the inter-blade spaces 110, one of which is shown in FIG. 2e, as obtained after the first through cut.
- the refinement cuts make it possible to approach closer to the final dimensions.
- the through-cut made from the first face 110a reveals a junction line 121a between the second face 110b and the surface of the block cut by the jet of abrasive water. Due to the three-axis nature of the through cut, this junction line 121a is substantially identical in shape to that of the cut line 118a left visible on the first face 110a of the block.
- all the refinement cuts are of complex shapes, called five axes, that is to say that the trajectory is obtained by moving the ejection head not only according to three degrees of freedom of translation, but also according to two degrees of freedom of rotation.
- these refining cuts are made on only part of the thickness of the block, so as to remove pieces each integrating at least a portion of the junction line 121a.
- each refining cutout makes it possible to cut out a particular zone of the block previously obtained by the through cut, which zone normally undergoes the most the effect of deflecting the water jet. abrasive encountered during this through cut, because it is at the outlet jet. Thus, since this particular area is reworked from the second face of the block, the deflection of the jet during the through cut can be important without it being harmful. This through cut can be made at a high cutting speed.
- a refining cut of a second piece 114b is then performed by moving the ejection head of the jet along an open line 118b generally having the shape of a U whose base runs along one of the two lengths of the junction line 121a, over substantially the entire radial distance from the blade preform, and the two legs of the U extend to this line 121a to contact it, as shown in Figure 2f.
- the second piece 114b aims to remove material near the leading edge 115 of one of the two blade preforms, as schematically shown in Figure 2c, while the removal of a third piece 114c has intended to remove material near the leading edge 115 of the other of the two blade preforms.
- the refining cut of the third piece 114c is operated by moving the jet ejection head along an open line 118c generally having the shape of a U whose base runs along the other length of the line junction 121a, over substantially the entire radial distance from the blade preform, and the two legs of the U extend to this line 121a to contact it, as shown in Figure 2f.
- all the pieces resulting from the refinement cuts fall automatically by gravity into the receptacle of the support.
- a piece may remain stuck in its associated inter-blade space after cutting.
- it is then split, by cutting by abrasive water jet, into two sub-pieces able to escape the block automatically by gravity, crossing the inter-blade gap formation. In this case, it is therefore under the sole effect of gravity that the two sub-pieces fall downwards by ending their fall in the receptacle of the support.
- the block has only the blade preforms 102 attached to each other at their head 108, by the ring 112.
- the abrasive water jet cutting step is then completed.
- Each blade preform 102 thus obtained therefore has an extrados surface 121 and an intrados surface 123, as shown in FIG. 2a.
- each of the extrados surface 121 and the intrados surface 123 is composed of surface portions resulting from the different cuts.
- Figure 2g schematically shows the segmentation of each of these two surfaces 121, 123 shown flat, each surface portion carrying the numerical value of the cut piece that made it appear.
- the manufacturing process is continued by the implementation of a milling step of the blade preforms 102, made so as to obtain blade blanks 202 set in profile.
- the objective of this step implemented for example using a five-axis milling tool, is to remove the remaining material on the blade preforms 102, in order to arrive closest to the final dimensions, for example at 0.6 mm. Due to the very refined shape of the preforms 102 obtained following the abrasive water jet cutting step, at least a portion of the surface of these preforms is already in the desired profile, and therefore does not require such milling.
- the preforms 102 are preferably machined one after the other, to each form a blade blank 202 set in profile, as shown in Figure 3 showing also the heads 208 of the blanks 202 interconnected by the ring 112 , still forming peripheral annular portion of the block 100.
- FIG. 4 shows schematically the separation of the ring 112 from the rest of the block 100, by breaking the connection between the ring 112 and the heads 208 of the blanks. Once all these substantially circumferential ruptures 228 have been obtained, the ring can actually be extracted from the block by relative movement along the axis 5 vis-à-vis the latter. Ring 112 is then considered deleted.
- the remaining block of material has a volume less than 25% of the volume of the same block as it was just before the initiation of the abrasive water jet cutting step, namely just after the above-mentioned turning step.
- the process may be continued by one or more conventional steps, among which, as indicated above, there is a polishing step, a shot blasting step, a step setting blade lengths, and / or a step of balancing the DAM.
