    A new cutting plate with a chip-breaker on at least one of the working faces, the plate being triangular or quadrilateral, with a preferably zero or positive back clearance and with a cutting angle which may generally be of any size but preferably positive. The plate is characterized in that the back clearance angle delta and cutting angle eta are obtained from cutting surfaces which are portions of conical surfaces with axes perpendicular to the plane Q gamma containing the main cutting points, that the cutting edge comprises at least one arc of a curve, representing the intersection between at least one cone and the plane Q alpha , and that the cutting surface adjoining a cutting point, comprising two consecutive surface elements joined along an arc of a curve in the plane bisecting the cutting point, causing discontinuity in the lines of level, is such that the cutting angle decreases as the plane No approaches the cutting point.

    one
    The invention relates to the field of metalworking.
    Known refillable cutting plate with a curved cutting edge and shaped front surface 1,
    The disadvantage of this plate is its inability to use it during the reverse course.
    The aim of the invention is to ensure the universality of the plate.
    For this purpose, the front face is formed by a set of parts of the surfaces of the cones, the number of which is a multiple of the number of corners of the polyhedron, and their line of intersection lies in the bisector plane of the corners, and the axes of the cones are perpendicular to the main plane.
    FIG. 1 shows a described cutting plate with a shaped front surface and curved cutting edges; in fig. 2 — plate, embodiment.
    Each curved cutting edge of the plate is formed by the intersection of the plane 1 passing through the side surface 2 of the plate, with the surface of the cone 3, the axis 4 of which is perpendicular to the main plane 5. The front surface is shaped and formed by a set of parts of the surfaces of the cones 3, with the number of These parts of the edges; The number of angles of the polyhedron, and the intersection line 6 of each pair of them is located in the bisector plane of the corresponding angle. The triangular plate depicted in FIG. 1 has three cr-and-linear edges 7, 8, 9 and, accordingly, three frontal shaped parts 10, 11, 12 intersecting in pairs.
    The plate depicted in FIG. 2 has six curved cutting edges 13, 14,. 15, 16, 17, 18, two on each face, and respectively six intersecting, in pairs, shaped parts 19, 20, 21, 22, 23, 24 of the front surface.
    The described plate ensures the work during the forward and reverse course and improves the direction and crushing of the chips.

    Invention Formula
    Multifaceted non-reversible plate with a curved cutting edge and a shaped front surface.
    characterized in that, in order to ensure the versatility of the plate, the shaped front surface is formed by soybeta parts of the surfaces of the cones, the number of which is a multiple of the number of angles of the polyhedron, and their line of intersection is
    in the bisector plane of the aforementioned angles, with the axes of the cones located perpendicular to the main plane.
