Abstract: A broaching tool includes at least one cutting zone with a cutting face that contacts a workpiece to remove material from the workpiece. At least one cavity corresponds to the cutting zone and is arranged to receive the removed material. A plurality of lubrication channels are supplied with lubricant, each lubrication channel having an inlet opening arranged to receive the lubricant and at least one outlet opening which opens into the cavity. The distance between the outlet openings of two consecutive lubrication channels varies further from the cutting face.

Abstract: A method for deburring an aeronautical part with an articulated tooling including a plurality of axes of rotation, the aeronautical part including at least one edge to be deburred, the articulated tooling including a tool holder, holding a calibration tool and a machining tool, the calibration tool and the machining tool being fixed to the tool holder and being immovable relative to one another, the method including steps of calibrating the calibration tool and the machining tool, of parameterizing the aeronautical part, of deburring the at least one edge to be deburred with the machining tool moving along a predetermined trajectory, on the basis of the parameters obtained during the parameterization step.

Abstract: An electrolyte for the electrochemical machining of a ?-?? nickel-based superalloy, includes NaNO3 in a content of between 10% and 30% by weight relative to the total weight of the electrolyte; a complexing agent selected from sulfosalicylic acid at a pH of between 3 and 10 and nitrilotriacetic acid at a pH of between 7 and 14, the complexing agent being present in a content of between 1% and 5% by weight relative to the total weight of the electrolyte; optionally, an anionic surfactant in a content of between 1% and 5% by weight relative to the total weight of the electrolyte; optionally, NaOH in order to obtain the desired pH; and an aqueous solvent.

Abstract: An electrolyte for electrochemical machining of a ?-?? nickel-based superalloy includes NaNO3 at a content of between 10 and 50% by weight relative to the total weight of the electrolyte; an additive chosen from KBr, NaBr, KI, NaI and mixtures thereof, in an additive/NaNO3 molar ratio of between 1 and 15; optionally an ethylenediaminetetraacetic acid-based complexing agent at a content of between 1 and 5% by weight relative to the total weight of the electrolyte at a pH of between 6 and 12; optionally an anionic surfactant at a content of between 1 and 5% by weight relative to the total weight of the electrolyte; optionally NaOH to obtain the appropriate pH; and an aqueous solvent.

Abstract: Tooling (10) for making slots in a multistage disk (1) by electrochemical machining. The tooling comprises first and second rings (20) arranged coaxially about a disk axis and configured to act as cathodes, each ring having an inside periphery with a plurality of radial machining projections. The first and second rings (20) are rigidly secured relative to each other. A method of making slots in a multistage disk by electrochemical machining using such a tool.

Abstract: A method of determining the wear of a flank of a cutter tool, in which the wear is determined by a general function calculating a characteristic length of the wear as a function of at least one variable that depends on time, is provided.
