Abstract
Ce procédé et cette machine visent à obtenir des gorges de grande précision, pouvant présenter une profondeur et un angle d'ouverture importants. A cet effet, on fait subir à la pièce 5 un mouvement de rotation autour d'un axe X-X, axe principal du tore, et un mouvement d'oscillation autour d'un axe Y-Y passant par le centre O d'une section élémentaire circulaire de ce tore. L'outil quant à lui subit un mouvement d'avance suivant une direction F, jusqu'à ce que la cote requise soit atteinte.This method and this machine aim to obtain high precision grooves, which can have a large depth and opening angle. To this end, part 5 is subjected to a rotational movement around an axis XX, the main axis of the torus, and an oscillating movement around an axis YY passing through the center O of a circular elementary section. of this torus. The tool itself undergoes a feed movement in a direction F, until the required dimension is reached.
