Abstract
A polygonal cutting has opposing first and second end surfaces connected by a side surface, and a plurality of cutting edges formed between the end surfaces and the side surface. Each cutting edge is formed at corner and includes a corner cutting edge and a major cutting edge connected to the corner cutting edge. A rake surface formed along the cutting edge on first the end surface is inclined toward the second end surface. In a side view of the cutting insert, the major cutting edge includes an inclined part which is inclined so as to approach the second end surface from the corner cutting edge. A portion of the rake surface along the inclined part is formed such that an angle of inclination toward the second end surface increases toward the corner in a direction along the intersecting edge between the first end surface and the side surface.
