Method and apparatus for adjusting the position of a cutting tool. In one embodiment, a boring tool (20) includes a coupling member (45) which is driven by a CNC boring machine, and a sliding tool holder (35) which is slidably coupled to the coupling member. A frictional force resist sliding movement of the cutting tool member (35). The frictional force is sufficient to retain the position of the cutting tool during machining operations. However, the frictional force is insufficient to resist a lateral force applied parallel to the direction of sliding, as used during adjustment of the tool position. In another embodiment, either a surface (1134) of the sliding tool holder (1135, 1135') or a surface (1458, 1458') of a frictional member (1450, 1450') are contoured with a shape that corresponds to a desired contour of a sidewall (1184a) of a hole (1184). During machining, a follower (1457b) in contact with the contoured surface (1458, 1458') causes the cutting tool holder to slide laterally during machining, thus contouring the sidewall of the hole.

L'invention concerne un procédé et un appareil destinés au réglage de la position d'un outil de coupe. Dans un mode de réalisation, un outil à aléser (20) comprend un élément de couplage (45) mis en mouvement par une machine à aléser CNC (à commande numérique par ordinateur) et un porte-outil (35) coulissant couplé de façon coulissante à l'élément de couplage. Une force de frottement s'oppose au mouvement de coulissement du porte-outil (35). Cette force de frottement suffit pour maintenir la position de l'outil de coupe durant les opérations d'usinage. Toutefois, cette force de frottement ne suffit pas pour résister à une force latérale appliquée parallèlement au sens de coulissement, comme il apparaît durant le réglage de la position de l'outil. Dans un autre mode de réalisation, soit une surface (1134) du porte-outil (1135, 1135') coulissant, soit une surface (1458, 1458') d'un élément de frottement (1450, 1450') est profilée de façon à correspondre à un contour désiré d'une paroi latérale (1184a) d'un orifice (1184). Lors de l'usinage, un suiveur (1475b) en contact avec ladite surface (1458, 1458') profilée fait coulisser latéralement le porte-outil, ce qui permet de façonner la paroi latérale de l'orifice.
