Cutting insert with angled supporting surface, toolholder with angled abutment surface, and cutting tool

摘要

A cutting insert includes two supporting surfaces and four side surfaces located between the two supporting surfaces. Each side surface intersects with two other side surfaces of the four side surfaces to form four corners. The four side surfaces intersect with the two supporting surfaces to form, at two of the four corners, four cutting corners, each cutting corner including a first and a second cutting edge component, and to form, at two other ones of the four corners, four non-cutting corners. Each supporting surface includes a surface portion and an angled supporting surface. A plane of the angled supporting surface intersects with a plane of the surface portion along a line of intersection and forms a non-zero angle with the plane of the surface portion. A toolholder and a cutting tool are also disclosed.

1. A cutting insert, comprising
two supporting surfaces; and four side surfaces disposed between the two supporting surfaces, each side surface of the four side surfaces intersecting with two other side surfaces of the four side surfaces to form four corners, the four side surfaces intersecting with the two supporting surfaces to form, at two of the four corners four cutting corners, each cutting corner including a first and a second cutting edge component, and to form, at two other ones of the four corners, four non-cutting corners, wherein each supporting surface includes a surface portion and an angled supporting surface, a plane of the angled supporting surface intersecting with a plane of the surface portion along a line of intersection and forming a non-zero angle with the plane of the surface portion, wherein the line of intersection on a first one of the two supporting surfaces is substantially perpendicular to the line of intersection on a second one of the two supporting surfaces.
