摘要： La presente invencion describe un inserto para aplicaciones de corte o fresado, en el cual una cara con ángulo de rebajo radial incluye una porcion conica concava, definida para lograr un ángulo de rebaje positivo constante a lo largo de la longitud de un borde de corte radial en el ángulo de inclinacion del mismo, cuando el inserto se propone para ser montado en el cuerpo de una herramienta de corte. El inserto incluye una cara con ángulo de rebaje axial, que tiene una porcion inclinada, definida para lograr un ángulo de rebaje axial positivo cuando el inserto se propone para ser montado en el cuerpo de una herramienta de corte. La superficie superior del inserto incluye regiones planas y superficies combinadas, que se fusionan suavemente con las caras con ángulo de rebaje radial y las caras con ángulo de rebaje axial, para asistir en la expulsion de las virutas durante el corte.

摘要： A cutting insert for metal cutting includes a body portion of a generally polygonal shape having a cutting end including a front end wall, sides, and top and bottom surfaces. The intersection of the top surface, end wall and sides forming a cutting edge. The top surface includes a cutting land of a generally concave shape about an axis longitudinally extending between the sides and sloping downwardly and inwardly from the cutting edge, a chipgroove area adjoining the cutting land and extending inwardly therefrom and disposed at a lower elevation than the cutting edge, and an upsloping chipbreaker portion adjoining the chipgroove area and the cutting land and leading to a plateau disposed at a higher elevation than the cutting edge and chipgroove area. The chipbreaker portion is configured symmetrically about the axis and includes a forwardly extending fingerlike projection on either side of and continuous with a rearwardly recessed region bisected by the axis.

摘要： An indexable threading and turning insert with integral pressed-in chip breakers, having a threading insert portion and a turning insert portion. Each of the threading insert portion and the turning insert portion has, respectively, an integral pressed-in chip breaker having ideal chip management characteristics. The indexable threading and turning insert has a substantially diamond shape having a first planar face, an opposite second planar face, and first, second, third and fourth insert faces extending between the first and second planar faces, wherein the threading insert portion is contiguous a first corner formed by intersection of the first and second planar faces and the turning insert portion is contiguous a second corner formed by intersection of the third and fourth insert faces, the second corner being located opposite the first corner. The threading insert portion is characterized by a first cutting edge formed at the intersection of the first insert face and a first land and a second cutting edge formed at the intersection of the second insert face and a second land. Each of the first and second cutting edges is provided with a plurality of noses separated by gullets. First and second integral, pressed-in chip breakers, each in the form of a raised island, the incident face contour thereof corresponding to the nose-and-gullet contour of the respective cutting edge adjacent thereto. Preferably, the incident face contour has scalloped portions adjacent the noses. The turning insert portion is characterized by third and fourth cutting edges located, respectively, at the intersection of a third land with the third and fourth insert faces, and at the intersection of a fourth land with the third and fourth insert faces. Third and fourth integral pressed-in chip breakers, each in the form of a raised island corresponding to the contour of the respective cutting edge adjacent thereto, preferably having a doublestepped, wing backed shape in registry with respect to the second corner.

摘要： The cutting insert has a polygonal body (12) with an upper surface (14) and a lower surface (16) joined to each other by a circumferential wall (18) with sides (20,22,24,26) and corners (28,30,32,34). At least one of the corners (28,32) has a radius and together with the upper surface defines a cutting edge (14). A cutting groove (42,44) formed on the upper surface extends inwards from the cutting edge (38). Two cutting surfaces (42,44) each have a positive cutting angle.
