摘要： A cutting insert according to an embodiment of the invention includes: an upper surface; a lower surface; a side surface which is connected to each of the upper surface and the lower surface, and includes a first side surface and a second side surface adjacent to each other; and a cutting edge including a major cutting edge located at an intersection of the upper surface and the first side surface, and a minor cutting edge located at an intersection of the upper surface and the second side surface. The upper surface includes a rake surface which is located along the major cutting edge, and is inclined downward as the upper surface separates from the major cutting edge. The second side surface includes a second upper constraining surface and a second lower constraining surface in order as the second side surface goes from the upper surface to the lower surface. The second upper constraining surface is inclined inward at an inclination angle ±1 with reference to a central axis extending between the upper surface and the lower surface. The second lower constraining surface is continuous with the second upper constraining surface, and is inclined outward at an inclination angle ±2 with reference to the central axis. A cutting tool with the cutting inserts, and a method of manufacturing a machined product by using the cutting tool are also provided.

摘要： A cutting tool of the present invention includes a cutting insert and a holder having at a front end part thereof an insert pocket for attaching the cutting insert. The insert pocket includes a seating part including a seating face which is brought into contact with the lower surface of the cutting insert, and is inclined forward in a rotation direction of the holder as the seating face separates from the front end part of the holder; and a constraining part brought into contact with first and second side surfaces adjacent to each other among the side surface of the cutting insert. The constraining part includes a curved portion; a first constraining face which is connected to one end of the curved portion and extends perpendicularly with respect to the rotation axis of the holder as the first constraining face separates from the curved portion, or extends away from the front end part of the holder; and a second constraining face which is connected to the other end of the curved portion and extends toward the front end part of the holder in the direction away from the curved portion. A method of manufacturing a machined product using the cutting tool is provided.
