Abstract: The present invention pertains to an automated polishing process for semi-finished mechanical parts in titanium or titanium alloy, using a machine with abrasive belt mounted on a tangential contact wheel driven in rotation at a determined speed and applied at a determined pressure, the wheel travelling with respect to the part's surface at a determined rate, characterized by the fact that the abrasive belt consists of superabrasive grains in industrial diamond or cubic boron nitride. The process is applied to geometric conforming of jet engine fan or compressor blades.

Abstract: The present invention relates to a precision-forging parts manufacturing process including the manufacture and development of a first forging tooling equipment (20, 30), the forging of the parts with said tooling equipment, whereas the parts have a determined excessive thickness, and their finishing treatment, The method is characterised in that it also includes the realisation of a digital model of the surface of the first tooling equipment, the forging of parts, the rehabilitation of the tooling equipment or the manufacture of new tooling equipment from the digital model, after forging a determined number of parts. In particular, the parts are subjected to a finishing treatment directly after forging, said treatment including mechanic polishing. The invention applies to the forging of blades for turbo machines.
