Abstract
Fraise en bout à extrémité sphérique ne comportant qu'une seule dent. Elle comprend un bord de coupe qui comporte une extrémité d'attaque disposée près du centre de rotation de la fraise et dont une partie est verticale. Le bord de coupe est délimité par une ligne qui s'incurve vers l'extérieur dans le sens de rotation de la fraise lorsqu'on l'observe du dessous. La courbure du bord de coupe est plus grande dans la partie centrale de la fraise que dans sa partie périphérique de façon à permettre au bord de coupe de commencer une opération de coupe par son extrémité d'attaque et d'effectuer ensuite progressivement la coupe dans une direction orientée radialement vers l'extérieur. Application au fraisage des filières réalisées en des matériaux extrêmement durs.
