摘要： An indexable cutting insert has opposing first and second polygonal end surfaces (2, 3) connected by a peripheral side surface (4). Sets of cutting edges (5) are formed at the intersection of each end surface with the peripheral side surface. Each set of cutting edges includes a corner cutting edge (6), first and second cutting edges (7), (8) on opposite sides of the corner cutting edge (6) and a wiper edge (9) formed between the second cutting edge (8) and the corner cutting edge (6). The peripheral side surface (14) includes a wiper-edge side surface (14) having constant width as it extends between the first and second end surfaces (2, 3). A boundary of the wiper-edge side surface (14) with a second side surface below the second cutting edge (8) is inclined with respect to a direction perpendicular to the first end surface.

摘要： A cutting insert (1) includes at least one cutting edge (8) formed on an intersecting ridge line portion between a rake surface (6) and a flank (7), and at least one ridge (12). The cutting edge includes a cutting edge portion (9) extending along a corner portion (5) and a straight-line shaped cutting edge portion (10) connecting to the cutting edge portion (9). The ridge (12) is formed to rise on the rake surface (6). The ridge (12) extends from a portion of a rake surface inside the cutting edge portion of the corner portion toward a rake surface inside the straight-line shaped cutting edge portion.

摘要： A cutting insert is provided with a plurality of cutting portions formed at the intersection portion of each end surface and a peripheral surface. Each cutting portion includes first and second cutting edges. First corners and second corners which differ in their internal angles are alternately formed in each end surface. An internal angle of the first corner is smaller than an internal angle of the second corner. Each first cutting edge has a portion extending to approach the median plane as a distance from a corresponding first corner increases. A first side surface portion extending on the peripheral surface from each first cutting edge forms an insert internal obtuse angle, and a second side surface portion extending on the peripheral surface from each second cutting edge forms an insert internal acute angle.

摘要： A cutting insert has cutting edge portions at intersection ridge portions between each of two end surfaces at the opposite side to each other and the peripheral side surface. Both the end surfaces are formed to be plane-symmetrical. In each end surface, long side portions and short side portions are alternately connected through raised corners or lowered corners. Each cutting edge portion is formed in regard to the raised corner, and has a corner cutting edge formed in the raised corner, a major cutting edge connected to the corner cutting edge and extending in the long side portion, and a minor cutting edge connected to the corner cutting edge at the opposite side and extending in the short side portion.
