Abstract
Le procédé concerne la réalisation d'une forme femelle (FF) du type dit « os de chien » dans une pièce mécanique (2), la forme femelle comprenant au moins une partie formant tête d'extrémité (21), le procédé comprenant des opérations d'extraction de matière par usinage. Conformément à l'invention, le procédé comprend les étapes suivantes : a) réaliser une ébauche de la partie formant tête d'extrémité par retrait rapide de matière avec des opérations de perçage au foret standard et/ou fraisage à la fraise cylindrique deux tailles standard, b) réaliser une rainure (20) formant une partie centrale fonctionnelle de la forme femelle par une opération de fraisage selon un axe central longitudinal (AC) de la forme femelle, et c) réaliser des première et deuxième zones fonctionnelles de serrage et d'appui (23) dans la partie formant tête d'extrémité, situées symétriquement de part et d'autre de l'axe central longitudinal, par une opération de contournage à la fraise.The method relates to producing a female form (FF) of the so-called "dog bone" type in a mechanical part (2), the female form comprising at least one end head portion (21), the method comprising material extraction operations by machining. In accordance with the invention, the method comprises the following steps: a) making a blank of the end-head portion by rapid removal of material with drilling operations using a standard drill and / or milling with a cylindrical milling cutter, two standard sizes , b) producing a groove (20) forming a functional central part of the female form by a milling operation along a longitudinal central axis (AC) of the female form, and c) producing first and second functional clamping zones and d 'support (23) in the end head portion, located symmetrically on either side of the longitudinal central axis, by a milling contouring operation.
