Abstract
A cutting insert has a first end surface and a second end surface which are opposed to each other. The first end surface has at least one apex and two side edges which extend so as to sandwich the apex. At least part of the two side edges serves as a cutting edge. The first end surface has a rake surface which is connected to the cutting edge. As viewed in a cross-section which intersects with the two side edges and which is orthogonal to the second end surface, the rake surface is inclined relative to the second end surface.
Claims19
A cutting insert comprising:
- a first end surface and a second end surface which are opposed to each other;
- and
- a peripheral side surface which connects the first end surface and the second end surface, wherein:
- as viewed from a direction facing the first end surface, the first end surface has at least one apex and two side edges which extend so as to sandwich the apex;
- at least part of the two side edges comprises a cutting edge;
- the first end surface has a rake surface connected to the cutting edge;
- as viewed in a cross-section which intersects with the two side edges and which is orthogonal to the second end surface, the rake surface is inclined relative to the second end surface;
- and
- as viewed from the direction facing the first end surface, when a bisector of an interior angle formed by respective extensions of the two side edges is defined,
- as viewed in a cross-section which includes the bisector and which is orthogonal to the second end surface, the rake surface is substantially parallel to the second end surface.

A cutting insert comprising:
- a first end surface and a second end surface which are opposed to each other;
- and
- a peripheral side surface which connects the first end surface and the second end surface;
- a longitudinal axis extending along a longest dimension of the insert and lying on a longitudinal plane which is perpendicular to the second end surface;
- and
- a transverse axis extending along widest dimension of the insert and lies on a lateral plane which is also perpendicular to the second end surface, the transverse axis intersecting the longitudinal axis at a right angle and being perpendicular to the longitudinal plane, the intersection of the longitudinal axis and the transverse axis defining a third plane which is parallel to the second end surface wherein:
- as viewed from a direction facing the first end surface, the first end surface has at least one apex and two side edges which extend so as to sandwich the apex;
- the longitudinal plane intersects the at least one apex;
- at least one of the two side edges comprises a cutting edge;
- the first end surface has a rake surface connected to the cutting edge;
- and
- in a cross-section parallel to the lateral plane and intersecting the two side edges, a thickness of the insert decreases in a direction from one of the two side edges to the other of the two side edges.
