摘要： A double-sided cutting insert with a plurality of indexable convex cutting edges can have a top face and a bottom face, at least three convex cutting edges on each face connected by at least three nose corners, at least three peripheral side surfaces extending from each face toward a virtual middle plane; and a common lateral seating surface on each peripheral side surface. Each convex cutting edge can have at least a curved cutting edge region, and can further have a primary substantially straight cutting edge region intermediate the curved cutting edge region and the nose corner. Each peripheral side surface can further have a primary planar facet associated with the primary substantially straight cutting edge, and each face may also be single-handed in same direction. Additionally, in various embodiments, the top and bottom faces of the cutting insert may be formed such that they are twisted or rotated with respect to each other. Further, additional cutting edges, edge regions, and/or surfaces may be included in a cutting insert in various embodiments. In such embodiments, the cutting insert or inserts may provide a powerful ramping function during milling operations.

摘要： A throwaway insert and a cutting tool enable a high speed cutting operation for a metallic material having great ductility such as aluminum and obtaining a vertical wall with a high quality machined surface while improving chip control. The throwaway insert comprises a major cutting edge including a tapered cutting edge connected to a cutting edge of a nose portion, and a curved cutting edge connected to an end of the tapered cutting edge at a connection point. The curved cutting edge is formed so as to extend along an imaginary cylindrical surface whose center axis coincides with the axis of rotation of a tool main body, and tapered cutting edge is formed so as to gradually curve from the imaginary cylindrical surface toward the inside of the imaginary cylindrical surface as the distance from the curved cutting edge increases, and the distance from the nose portion decreases. The throwaway insert is attached to the tool main body in which the surface of the distal end thereof is machined so that surface roughness thereof is less than 3.2 μm when indicated by the Ry roughness.

摘要： A cutting tool, preferably for milling, includes a holder and a cutting insert mounted thereon. The holder includes a seat upon which the insert is mounted, and an upstanding wall structure against which an edge face of the insert is pressed. The edge face has upper and lower portions separated by a step. The upper portion is frustoconical and is pressed against an upper wall of the wall structure to frictionally resist rotation of the insert about the insert's center axis. The lower portion of the edge face is polygonal and is adapted to engage a lower wall of the wall structure at a location spaced radially inwardly from a location where the upper portion and upper wall make contact. The lower portion rotates into engagement with the lower wall in response to cutting forces acting on the insert, to create an interference relationship between the lower portion and lower wall which prevents further rotation of the insert.

摘要： A cutting insert includes a first surface and a second surface each of which is polygonal and that face away from each other; a side surface that is continuous with the first surface and a side surface that is continuous with the second surface; a cutting edge formed along each of a ridge where the first surface and the side surface intersect and a ridge where the second surface and the side surface intersect; a bearing surface formed in each of a part the first surface and a part of the second surface adjacent to an insert center, the bearing surfaces disposed parallel to each other; and a recessed portion that separates the side surface that is continuous with the first surface from the side surface that is continuous with the second surface. The cutting edge includes three corner edges, a first cutting edge, and a second cutting edge, the first and second cutting edges being continuous with each other and located between each pair of the corner edges. A length of the first cutting edge is greater than that of the second cutting edge, an end portion of the first cutting edge adjacent to one of the corner edges is at a position higher than the bearing surface, and an end portion of the first cutting edge opposite to the end portion adjacent to the corner edge is at a position lower than the bearing surface. Each of the first surface, the second surface, and a cross section of the recessed portion has such a shape that outlines of the shape before and after rotation of the insert by 120° around the insert center are coincident with each other. The first surface and the second surface have the same shape, and the second cutting edge of the second surface is located at a corner at which the first cutting edge of the first surface is located.

The cutter region has a planar cutting edge running approximately perpendicularly to the axis of rotation D and merges peripherally into a main cutting edge and centrally into a secondary cutting edge. The secondary cutting edge is offset rearwardly from the planar cutting edge in the direction of the axis of rotation D. The transitional zone between the planar cutting edge and the secondary cutting edge has a notch produced as a cutting edge portion. The rearmost point of this notch, as seen in an end view in the direction of the axis of rotation D, lies behind the forward-most point of the secondary cutting edge, the angle α between the planar cutting edge and the adjoining portion of the notch lying in the range of 90° to 175°, and the angle β between the planar cutting edge and that portion of the notch adjoining the secondary cutting edge lying in the range of 3° to 90°. The angle γ between that portion of the notch adjoining the secondary cutting edge and the secondary cutting edge lies in the range of 90° to 177°.

摘要： A cutting tool for a milling, drilling or turning machine has a body with a plurality of sides and a central opening. Each side has a perimeter along which cutting planes or edges are formed. Each side has at least two such cutting planes or edges. The planes may have a straight or curved profile, or a combination of straight and curved profiles along one side. The tool may have a plurality of such cutting planes formed along each side of the tool body. The cutting planes may be located at different levels in relation to each other, entering a work piece in sequence, or may be aligned to enter the work piece simultaneously. Preferably, the cutting planes are staggered in two directions—in a feeding direction and in a cutting direction. By dividing each surface being cut into a plurality of segments, the cutting tool creates a plurality of distinct shavings, or splinters that have shorter length in comparison with conventional splinters formed by indexable tips. Shorter cuts require less cutting force, which saves wear on the cutting tool and the machine. At the same time, the cuts can be made deeper and smoother when dividing the cutting surface into a plurality of segments.
摘要翻译： 用于铣削，钻孔或车削机床的切削工具具有多个侧面和中心开口的主体。 每一侧都有一个周边，形成切割平面或边缘。 每侧具有至少两个这样的切割平面或边缘。 平面可以具有直的或弯曲的轮廓，或者沿着一侧具有直的和弯曲的轮廓的组合。 工具可以具有沿着工具主体的每一侧形成的多个这样的切割平面。 切割平面可以相对于彼此位于不同的水平位置，顺序地进入工件，或者可以对齐以同时进入工件。 优选地，切割平面在进给方向和切割方向上沿两个方向错开。 通过将被切割的每个表面划分成多个段，与由可转位尖端形成的常规碎片相比，切割工具产生多个不同的切屑或碎片，其具有较短的长度。 较短的切割要求较少的切割力，从而可以节省刀具和机器的磨损。 同时，当将切割表面分成多个段时，可以使切割更深更平滑。
