Abstract
On bloque un rotor comportant une pluralité de rainures axiales qui ont été préalablement définies. Des outils sont appliqués radialement contre les portions de surface cylindrique séparant les rainures consécutives du rotor. L'extrémité des outils a une forme adaptée pour venir en contact contre les surfaces cylindriques de manière à épouser ces dernières. Chaque outil comporte deux protubérances formant poinçon ayant une forme déterminée, et destinées à former des chanfreins dans les bords adjacents de rainures consécutives en repoussant le métal au fond de ces dernières.
