摘要： A four-sided cutting insert has a top surface, a bottom surface, and a pair of first side surfaces connected to a pair of second side surfaces via corner surfaces. The cutting insert has a rotational axis of symmetry, a first axis extending along the first side surfaces and second axis extending along the second side surfaces. Opposite corners of the cutting insert are provided with a first pair of corner edges defined between a first edge and an associated second edge. Proximate its leading end, the first edge has a main portion which, in a top view of the insert, extends inwardly toward the first axis at a first angle. In a side view, the first edge slopes downwardly from the corner edge in the direction of the base surface. The associated second edge, in the top view of the insert, extends from the corner edge in an outward direction relative to the second axis.

摘要： A cutting insert having a pentagonal prismatic shape. A cutting region is associated with each polygonal side and is elevated with respect to a central tangential abutment surface. A primary cutting edge associated with a polygonal side is formed at the intersection of a primary rake surface and a primary relief surface. A secondary cutting edge associated with a rounded corner is formed at the intersection of a secondary rake surface and a secondary relief surface and merges with the primary cutting edge. The primary relief surface forms with the associated side abutment surface a primary relief surface angle that varies from a maximal value adjacent an upper end of the primary cutting edge to a minimal value. The secondary relief surface forms with the associated rounded corner a secondary relief surface angle that varies from a maximal value adjacent the primary cutting edge to a minimal value.

摘要： A method for manufacturing a cutting insert green body having undercuts includes providing a die cavity formed in closed top and bottom dies; closing a bottom of the die cavity by a bottom punch accommodated in a punch tunnel formed in the bottom die; filling the die cavity with a pre-determined amount of sinterable powder; moving a top punch towards the die cavity through a punch tunnel formed in the top die; compacting the powder by urging the top and bottom punches towards each other, thereby forming the green body; and moving the top die and punch away from the bottom die and punch, thereby enabling removal of the formed green body. An apparatus for manufacturing a cutting insert green body having undercuts includes top and bottom dies which abut each other and top and bottom punches which slide in their respective dies.

摘要： A double-sided reversible and indexable cutting insert has identical opposing first and second end faces and a peripheral side surface extending therebetween. A clamping through-bore extends between, and opens out to, the first and second end faces. The cutting insert has a median plane between the first and second end faces, and a through-bore axis extending perpendicularly through the median plane. The cutting insert also has a Y-fold rotational symmetry about the through-bore axis. The peripheral side surface has Y major side surfaces and Y minor side surfaces, each minor side surface interconnecting two adjacent major side surfaces. Each minor side surface is a section of a single cylindrical surface having a given radius, the given radius being greater than a minor side surface distance of each minor side surface from the through-bore axis.

摘要： A double-sided cutting insert, for use in a milling cutter, having two identical opposing end surfaces and two opposing identical major side surfaces with a through bore extending between, and opening out to, the major side surfaces. Major cutting edges are formed at the intersection of each major side surface with each end surface. Adjacent each major cutting edge, in each major side surface, is a primary relief surface. In each cross section of the cutting insert taken in a plane generally perpendicular to the major side surfaces, a line tangent to the primary relief surface at the major cutting edge is inclined to a median plane of the cutting insert at an acute interior angle.
