Abstract:
In the cutting insert of the present invention, the cutting edge portion includes: a first corner edge; a major cutting edge continuous with a first end portion (S 1 ) of the first corner edge near the short-side-direction side surface and formed into a straight line; a first minor cutting edge continuous with a second end portion (S 2 ) of the major cutting edge and formed into a circular arc; and a second minor cutting edge continuous with a third end portion (S 3 ) of the first minor cutting edge and formed into a straight line. In a cross-sectional view of a rake face of the second minor cutting edge perpendicular to the second minor cutting edge, a cross-sectional ridgeline of the rake face of the second minor cutting edge is formed into a convex shape protruding above a cross-sectional ridgeline of a reference plane.

Claim (Index 1):
A cutting insert comprising:\n a top surface and a bottom surface each having long sides and short sides and each formed into substantially quadrilateral in a plan view of the top surface and the bottom surface, the bottom surface being arranged to be opposite to the top surface; corner portions formed at four corners of each of the top surface and the bottom surface; two long-side-direction side surfaces and two short-side-direction side surfaces which are side surfaces connecting the top surface and the bottom surface; a clamp screw insertion hole penetrating from a center portion of the top surface to the bottom surface; and cutting edge portions having cutting edges at intersecting ridgelines at which the top surface and the bottom surface intersect with the long-side-direction side surfaces and the short-side-direction side surfaces, wherein the cutting edge portions comprises:\n first corner edges formed at a pair of first corner portions among the four corners of each of the top surface and the bottom surface, the pair of the first corner portions being arranged so as to face each other across a center line of the clamp screw insertion hole; \n major cutting edges connected with first end portions (S 1 ) of the first corner edges near the short-side-direction side surface and each formed into a straight line along the intersecting ridgeline of the short-side-direction side surface; \n first minor cutting edges connected with second end portions (S 2 ) of the major cutting edges, each gently protruding toward outside of the short-side-direction side surface in the plan view of the top surface and the bottom surface, each extending away from the second end portion (S 2 ) so as to gradually retract toward the clamp screw insertion hole with respect to an extended line of the major cutting edge, and each formed into a circular arc with a radius R; and \n second minor cutting edges connected with third end portions (S 3 ) of the first minor cutting edges and each formed into a straight line, \n wherein the top surface and the bottom surface each comprise a reference plane formed to include a circumference of an opening of the clamp screw insertion hole, and wherein in a cross-sectional view of a rake face of the second minor cutting edge perpendicular to a ridgeline of the second minor cutting edge, a cross-sectional ridgeline of the rake face of the second minor cutting edges is formed into a convex shape protruding above the top surface or the bottom surface with respect to a cross-sectional ridgeline of the reference plane.
