Abstract
A process carried out by an apparatus for cutting a tubular bar comprises a first cutting stage performed by a first disc-shaped rotary cutting tool, oriented so as to rotate about an axis parallel to a line of extension of the bar and also movable gradually along the contour of the bar, which is made to penetrate into the peripheral wall of the bar over a distance less than the thickness thereof, forming a groove therein. In a second and successive cutting stage, a second stationary cutting tool, oriented transversely with respect to the line of extension of the bar and movable along the contour of the bar inside the groove, is made to penetrate into the remaining thickness of the peripheral wall so as to cause gradual shearing of the bar.
