摘要： A cutting insert of an embodiment of the present invention includes: a polygonal shaped upper surface; a lower surface being identical in shape to the upper surface; a side surface connected to each of the upper and lower surfaces; and an upper cutting edge located at the intersection of the upper surface and the side surface. The upper surface alternately includes three major corners, each having a first interior angle, and three minor corners, each having a second interior angle larger than the first interior angle. The upper cutting edge includes: a corner cutting edge; a minor cutting edge inclined toward the lower surface as separating from the corner cutting edge at a first inclination angle on the basis of a vertical plane perpendicular to a central axis extending between the upper and lower surfaces; and a major cutting edge inclined toward the lower surface as separating from the minor cutting edge at a second inclination angle larger than the first inclination angle on the basis of the vertical plane. The corner cutting edge, the minor cutting edge and the major cutting edge are located sequentially from a first major corner of the three major corners to each of first and second minor corners of the three minor corners, both of which are adjacent to the first major corner. A cutting tool with the cutting insert, and a method of manufacturing a machined product by using the cutting tool are also provided.

摘要： A first lateral surface of a cutting insert in a non-limiting embodiment of the present disclosure includes a first region, a second region, and a third region. The first region includes a first upper region inclined outward, and a first lower region that is connected to the first upper region and is parallel to a central axis. The second region includes a second upper region inclined inward, and a second lower region that is located closer to a lower surface than the second upper region and is parallel to the central axis. The third region includes a third upper region inclined outward, a third lower region, and a concave part. The third lower region is located closer to the lower surface than the third upper region, and is located more outside than the third upper region and is parallel to the central axis. The concave part is located between the third upper region and the third lower region.

摘要： This cutting insert is provided with a lower surface of polygonal shape including side parts and a pair of corner parts, an upper surface, a lateral surface situated between the lower surface and the upper surface, a pair of corner cutting edges located at the pair of corners at a line of intersection of the upper surface and the lateral surface, and a main cutting edge located in a side portion at a line of intersection of the upper surface and the lateral surface. The main cutting edge is upwardly convex in shape, and in side view includes an upwardly convex curving portion, and a pair of linear portions respectively extending toward the pair of corner cutting edges from the curving portion. The top portion of the curving portion is positioned more toward the one of the corner cutting edges which, of the pair of corner cutting edges, is that contiguous to the working surface of the work material during cutting of the work material.

摘要： In a cutting insert of an embodiment of the present invention, an upper surface includes a first corner, and a second corner and a third corner respectively adjacent to both sides of the first corner. The upper surface sequentially includes a rake surface located along an upper cutting edge and inclined toward a lower surface as going inward from the upper cutting edge at a rake angle on a basis of a perpendicular plane perpendicular to a central axis extending between the upper and lower surfaces, and a connection surface located more inward than the rake surface and inclined toward the lower surface as going inward at a connection angle on the basis of the perpendicular plane. An intersecting part of the rake surface and the connection surface includes a highest position in a portion of the intersecting part corresponding to the minor rake surface. A cutting tool with the cutting insert, and a method of producing a machined product by using the cutting tool are also provided.
