It relates in particular turbomachinery blades and in particular large blades such as than fan blades in a turbojet engine and aims in particular at a method of manufacturing such blades implementing said polishing.
- Abrasive belt polishing is used in particular in the context of of a method of geometrical conformity of semi-finished blades forging for example.
- a polishing thickness is removed by polishing determined matter.
- the conventional abrasive material removes an insufficient quantity of material by passage of the wheel with the band, which requires additional operations of removal of material and thickness control.
- a compliance process geometry of a semi-finished forged blade include machining chemical before polishing. After polishing the room a first time with a certain grain, we must proceed again to a chemical machining and manual retouching on straight electric grinders or with reels or other portable machine.
- the present invention aims at overcoming the disadvantages encountered with abrasive belts of the prior art.
- the method of automated polishing of parts mechanical titanium or titanium alloy semi-finished, by means of a machine with an abrasive belt mounted on a tangential contact wheel driven in rotation with a speed and applied with a pressure determined, the wheel moving relative to the surface of the piece with a determined speed is characterized in that the abrasive belt is consisting of super-abrasive grains of industrial diamond or nitride cubic boron.
- the abrasive layer of the tape is more accurate. For example in the case of Diamond band formation is done through an electrochemical deposit more homogeneous.
- the super abrasive grains are supported by a layer of nickel which is itself secured to a polyester base. The layer of nickel absorbs heat and avoids work hardening.
- the quantities of material are removed with a very thick dispersion low.
- This low dispersion has a significant advantage in the the geometrical alignment of blades from semi-finished parts with determined thickness. The removal of material is carried out with a deviation from the setpoint sufficiently low for that one stays inside the tolerance band of shape of the blade. We thus avoids the need for manual adjustments by grinding.
- the extra thickness is between 2/10 and 4/10 mm.
- the contact wheel is grooved with grooves arranged obliquely with respect to the axis of rotation of the wheel.
- the angle is in particular 25 to 35 °.

- the head 100 can be move horizontally in the Y direction perpendicular to the direction X and rotate in the direction V around this axis.
- Driving means My and Mv provide these trips.
- the head 100 supports a wheel 110 of movable contact about an axis which is fixed relative to itself.
- a motor mounted on the head 100 ensures the drive of the wheel 110 by the an abrasive belt which is mounted on the periphery of the wheel.
- All the motor means is connected to a control box which comprises a control unit with programming means and memories incorporating in particular the geometrical data of the room to polish.
- the strip is applied locally tangentially to its surface by exerting a determined pressure and it sets it in motion. She turns with the wheel around her axis.
- the desired removal value and surface condition depend both on the grain of the band but also machine parameters applied as well as characteristics of the contact wheel.
- These parameters are determined for a well-defined wheel, as well geometrically only according to the quality of the material that constitutes it.
- the wheel has on the surface grooves inclined at 30 °, 3 mm wide and 17 mm apart.
- the material at the periphery of the wheel is a rubber, hardness determined, for example 70 shore.
- Such a machine is used in connection with Geometric conformity and finishing by polishing a semi-finished part.
- the semi-finished part coming from the forging station has a shape and dimensional characteristics close to the finished part. However, his odds are not yet final because of a determined thickness. In the context of precision forging, this allowance is fixed from 2/10 to 4/10 mm.
- the polishing operation Automated is intended to remove this extra thickness.
- the next stage of preparation consists of a chemical machining.
- the titanium alloys are chemically dissolved in a bath composed of nitric acid, hydrofluoric acid and other agents such as wetting agents or water.
- the immersion time in the bath determines the amount of material removed.
- the advantage of machining chemical is to remove a uniform material thickness, regardless of its shape.
- the two operations are repeated until a determined allowance that the polishing operation is responsible for eliminating.
- the polishing operation by passing the workpiece through a machine having an abrasive belt is in itself known. We proceed to a polishing said first appearance.
- a strip is used, the abrasive of which is carbide silicon and whose grain is for example 120.
- the abrasive of which is carbide silicon and whose grain is for example 120.
- Finishing polishing is done with a band with a grain larger end.
- the removal is, for example, 0.1 mm +/- 0.05 mm. Final validation of geometry with retouching manual is possibly necessary.
- a strip is used with super-abrasive grains such as industrial diamond grains or boron nitride cubic.
- FIG. 3 shows a schematic section of a strip 200 in representing its structure; the support 210 is a synthetic material based for example polyester. On this support are hung 220 grains of nickel. These are themselves used to support super-abrasive particles such as industrial diamond or cubic boron nitride.
- the Electrochemical deposition which ensures the formation of a homogeneous abrasive layer.
- Such abrasive belts are commercially available and provided for example by the companies 3M, Saint Gobain Abrasives or KGS
- the semi-finished part has been prepared so as to present a overthickness in relation to the desired dimension, precisely defined as either by chemical machining, geometric adjustment by retouching manual (for example using carbide milling cutters on straight grinders electrical devices) or a combination of both operations, one reaches the room presenting the desired dimensions directly by polishing by means of such bands. There is no need for manual adjustment between two polishings one said first appearance, the other said finishing. We stay remarkably within the form tolerance imposed by the specifications.
- Polishing first appearance with a 60 grit diamond band removes a quantity of material of 0.3 mm +/- 0.05 mm and ensures a state of area of 1.8 ⁇ m.
- Polishing in the final appearance using a 220 grit diamond band removes a quantity of material of 0.1mm +/- 0.01mm and ensures a surface state of 0.8 ⁇ m.
- the final validation operation which consists of a dimensional control and appearance can be carried out without the use of the drum or machine portable polish.
- polishing first aspect or blank by any known means such as machining chemical, manual polishing or any mechanical polishing, as far as where polishing finishing or said in final appearance is done by the polishing technique with diamond band.
- the first aspect polishing is performed on a overthickness defined to allow removal of material between 0.1 mm and 0.8 mm, preferably between 0.2 mm and 0.4 mm and more particularly, as reported previously, 0.3 mm +/- 0; 05 mm.
- Finishing polishing using the diamond band with a fine grain is made in such a way as to ensure a removal of material between 0.01 and 0.2 mm +/- 0.01 mm and preferably 0.1 mm +/- 0.01 mm.

Abstract
Description
Les bandes s'usent rapidement. Pour des aubes de soufflante de turboréacteur par exemple, on consomme deux bandes par pièce lors de la mise en conformité géométrique à partir d'une ébauche semi-finie.
Le matériau abrasif pollue le titane. Des précautions doivent être prises pour l'éviter.
Le dépôt de l'abrasif sur les bandes que l'on trouve dans le commerce est réalisé en général par des moyens électrostatiques. La régularité du dépôt n'est pas optimale. Elle conduit à une certaine dispersion en terme d'enlèvement de matière. Le polissage n'est pas homogène. Il s'ensuit la nécessité de procéder à des ajustages manuels de l'enlèvement de matière associés ou non à des rééquilibrages des épaisseurs.
- Force d'application de la roue sur la surface de la pièce : 137N à 196N
- Vitesse de défilement de la bande : 4,6 m/s à 18,6 m/s
- Plage d'avance relative de la roue par rapport à la pièce 3,4 m/min à 6,7 m/min.
- la figure 1 représente schématiquement une machine de polissage pour la mise en oeuvre du procédé de l'invention,
- la figure 2 est une vue latérale de la machine de la figure 1,
- la figure 3 représente en coupe une bande utilisée dans le cadre de l'invention.
- la force (N) exercée par la roue de contact sur la pièce,
- la vitesse déplacement relative de la bande le long de l'axe de la pièce, ici l'axe X,
- la vitesse de défilement de la bande (m/s) sur la pièce dans la direction de rotation de la roue.
- La plage de force de pression exercée par la roue de contact sur la pièce est de 137N à 196N.
- La plage d'avance de la table est de 3,4 m/min à 6,7 m/min.
- La plage de la vitesse de défilement de la bande abrasive diamant est de 4,6 m/s à 18,6 m/s. La roue de contact utilisée a les caractéristiques suivantes
- Roue de largeur de 25 mm avec un diamètre extérieur adapté à la géométrie des pièces.
- Rainures définies de façon à avoir suffisamment d'agressivité en terme d'enlèvement de matière.
- Matériau constituant la roue adapté à l'opération et de type caoutchouc.
