A main blade (12a-d) is provided between each base surface (14a, b) and each main lateral surface (16a, b), and each main lateral surface (16a, b) has two diagonally opposite first partial blades (26a-d), each of which adjoins a first end (28a-d) of the respective main blade (12a-d). The main blades (12a-d) and the first partial blades (26a-d) of each main lateral surface (16a, b) each lie in a blade plane that runs perpendicular to the x axis. Finally, the first partial blades (26a-d) are each formed on a first projection (24a-d) that is provided on the secondary lateral surfaces (18a, b) and defines a first clearance angle (α).

摘要： A cutting insert (1) of the present invention comprises a first end surface (2) and a second end surface (3) which are opposed to each other and a peripheral side surface (4) connecting the first end surface (2) and the second end surface (3), and has a central axis (O) defined so as to penetrate these end surfaces. A major cutting edge (8) and a minor cutting edge (10), which are connected via a corner cutting edge (9), are formed along an intersecting edge between the first end surface (2) and the peripheral side surface (4). The peripheral side surface has a first side surface part (4a) related to the major cutting edge and a second side surface part (4b) related to the minor cutting edge. The first side surface part (4a) gradually extends outward from the cutting insert, heading from the first end surface to the second end surface. When a second virtual plane (L1), which is substantially perpendicular to the central axis (O) and passes through the major cutting edge (8), is defined, an inclined part (3a), on a back side of the cutting edge, of the second end surface (3) is inclined so as to become more distant from the second virtual plane (L1), heading from the first side surface part (4a) to the central axis (O).

摘要： A cutting insert includes an insert body 1 having a polygonal plate shape. Rake faces 3 are formed on polygonal surfaces of the insert body 1, and flank faces 4 are formed on lateral faces of the insert body 1 arranged around the polygonal surfaces. Main cutting edges 5 are formed on side ridges of the polygonal surfaces at intersecting ridgelines between the rake faces 3 and the flank faces 4. Each main cutting edge 5 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 3, one end portion 5a of the main cutting edge 5 that stretches to one corner of the two corners has a convexly curved shape, and the other end portion 5b of the main cutting edge 5 that stretches to the other corner of the two corners has a concavely curved shape.
