    摘要： A cutting insert according to an embodiment of the present invention has an upper surface, a lower surface, a side surface connected to each of the upper surface and the lower surface, and a cutting edge located along an intersection of the upper surface and the side surface. The upper surface has a land surface disposed along the cutting edge, a rake surface which is located further inside than the land surface and is inclined so as to have a smaller height as departing from the land surface, and a bottom surface located further inside than the rake surface. The rake surface has a projection-shaped first region and a concave-shaped second region which are alternately disposed along the bottom surface. The first region has a first recess that reaches the second region adjacent to the first region.

    摘要： A cutting tool for machining large workpieces having relatively a large cutting amount and a cutting insert configured to be used with the cutting tool. The cutting tool includes a cutting insert and a wedge for clamping the cutting insert. The cutting insert has a polygonal top surface, which comprises a recessed portion having a plurality of inclined abutment surfaces which are inclined toward the center of the top surface. The outline of said recessed portion is twisted at a predetermined angle with respect to the outline of the top surface. The wedge includes a projecting portion that contacts the inclined abutment surface and pushes the cutting insert so that two side surfaces of the cutting insert can be supported by a radial inner side surface and a lateral supporting surface of an insert seat.

    摘要： A double negative cutting insert has opposite top and bottom sides between which transverse flank surfaces extend, adjacent to which cutting edges are formed. There are at least four useful major cutting edges, which separately extend from an active operating corner towards a nearby first inactive corner. Each major cutting edge co-operates with a minor cutting edge with the purpose of face machining the surface, that is left after material removal. The cutting insert has an octagonal basic shape, the top and bottom sides thereof having an identical shape with four spaced-apart supporting projections, which are placed near the four inactive corners and have plane abutment surfaces located in a common plane. An individual land adjacent to the major cutting edges has a concavely arched shape in order to provide a positive cutting geometry during operation.

    摘要： A cutting insert for mounting on a milling cutter has a generally quadrangular shape with top and bottom surfaces, a pair of opposite first side surfaces intersecting the top surface at first cutting edges and a pair of opposite second side surfaces intersecting the top surface at second edges. Each second edge has a front cutting portion oriented substantially transversely to an adjacent first cutting edge and meeting therewith via a cutting corner. Each of the first and second side surfaces has upper and lower sections adjacent respective top and bottom surfaces, which sections have leading portions adjacent their associated cutting corner and trailing portions remote therefrom. The trailing portion of the lower section of each second side surface is at least slightly inwardly depressed relative to the leading portion of the lower section and is substantially inwardly depressed relative to the associated trailing portion of the upper section of the second side surface. The trailing portions of the lower and upper sections merge via a transition surface oriented transversely thereto.

    摘要： A cutting insert includes an insert body having a polygonal plate shape. Rake faces are formed on polygonal surfaces of the insert body, and flank faces are formed on lateral faces of the insert body arranged around the polygonal surfaces. Main cutting edges are formed on side ridges of the polygonal surfaces at intersecting ridgelines between the rake faces and the flank faces. Each main cutting edge extends between two corners adjacent to each other in a circumferential direction of the polygonal surface among corners of the polygonal surface. When seen from a direction opposing the rake face, one end portion of the main cutting edge that stretches to one corner of the two corners has a convexly curved shape, and the other end portion of the main cutting edge that stretches to the other corner of the two corners has a concavely curved shape.
