摘要： The present invention relates to a cutting insert. The cutting insert has top and bottom surfaces in the thicknesswise direction, and front and rear surfaces in the widthwise direction. First and second cutting edges are formed in the lengthwise direction at intersection portions where the top surface intersects with the front and rear surfaces. Third and fourth cutting edges are formed in the lengthwise direction at intersection portions where the bottom surface intersects with the front and rear surfaces. The first to fourth cutting edges are divided by a plurality of recesses. The plurality of recesses is symmetric with respect to the lengthwise centerline (A), which runs between the first and third cutting edges on the front surface, and is asymmetric with respect to the thicknesswise centerline (B) perpendicular to the lengthwise centerline (A).

摘要： The present invention provides a cutting insert comprising a top surface, a bottom surface, a plurality of side surfaces that connect the top and bottom surfaces and form an obtuse angle with the bottom surface as well as an acute angle with the top surface. The side surfaces comprise a first side surface and a second side surface, which form an obtuse angle with each other when seen from the above. A main cutting edge is formed at an intersection between the first side surface and the top surface. An inclined cutting edge, which is only for ramp milling, and a minor cutting edge are formed at an intersection between the second side surface and the top surface. An obtuse angle, which the second side surface forms with the bottom surface, is greater than that which the first side surface forms with the bottom surface.
