Abstract:
A cutting insert ( 1 ) according to an embodiment has a lower surface ( 2 ), an upper surface ( 3 ), a side surface ( 4 ) disposed between the lower surface ( 2 ) and the upper surface ( 3 ), a pair of corner cutting edges ( 5 ) located along an intersection of the upper surface ( 3 ) and the side surface ( 4 ), and a major cutting edge ( 6 ) located between the pair of corner cutting edges ( 5 ). The major cutting edge ( 6 ) has a downwardly dented curvilinear part ( 61 ) and a pair of straight parts ( 62 ) respectively extending from the curvilinear part ( 61 ) toward the pair of corner cutting edges ( 5 ) in a side view. A portion ( 6 p ) of the curvilinear part ( 61 ) located lowermost is close to one corner cutting edge ( 5 b ) in the side view.

Claim (Index 1):
A cutting insert, comprising:\n a polygonal shaped upper surface comprising a pair of corner parts and a side part located between the pair of corner parts; a polygonal shaped lower surface corresponding to the upper surface; a side surface disposed between the lower surface and the upper surface; a pair of corner cutting edges located along an intersection of the pair of corner parts of the upper surface and the side surface; and a major cutting edge located along an intersection of the side part of the upper surface and the side surface, wherein the major cutting edge has a downwardly dented concave shape as a whole, and comprises\n a first section having a downwardly dented concave curvilinear shape in a side view, and \n a pair of second sections being in a shape of a straight-like line, the pair of second sections respectively extending from the first section toward the pair of corner cutting edges and having a larger height as approaching the pair of corner cutting edges, and \n wherein a portion of the first section which is located lowermost is close to one of the corner cutting edges in the side view.
