Abstract: A cutting tool includes a pocket with a top wall, a bottom wall, a side wall and a rear wall. The cutting tool has an insert cartridge and a wedge clamp. The threaded member exerts a force vector in a radial direction when threaded into the wedge clamp to place the cutting tool in a locked condition, and the wedge clamp exerts a force vector into the body of the cutting tool radially inward of an adjacent pocket, thereby reducing deflection of the adjacent pocket when the cutting tool is placed in the locked condition.

Abstract: A cutting insert for a cutting tool is described. The cutting inserts generally square-shaped with two opposing surfaces and four peripheral side surfaces. Cutting edges are formed at the intersection between the first and second surfaces and the peripheral side surfaces. Each cutting edge is divided into a first portion, a second portion and a radius blend. The first portion has a length, L1, and the second portion has a length, L2, that is shorter than the first portion such that the radius blend is not located at a midpoint of the cutting edge, thereby increasing a height of the ninety-degree shoulder that can be cut by the cutting insert.

Abstract: An indexable cutting insert having a top surface, a bottom surface, and a plurality of side surfaces. A main cutting edge, a ramping cutting edge, a wiper cutting edge, and a nose radius cutting edge are formed at the intersection between the top surface and the side surfaces. Two diagonally side surfaces further comprise a first side surface and a second side surface. The second side surface extends the entire length of the main cutting edge. The first and second side surfaces and two other side surfaces contact an insert pocket of the milling cutter when the cutting insert is mounted the insert pocket of the high-speed milling cutter, thereby providing four-point contact between the cutting insert and the insert pocket.

Abstract: A cutting insert for heavy machining operations is described. The cutting insert has two opposing end surfaces, two identical opposing major side surfaces and two identical opposing minor side surfaces. The cutting insert further includes a major cutting edge formed at an intersection of each major edge and the end surface, and a minor cutting edge formed at an intersection of each minor edge and the end surface, and a corner cutting edge formed at an intersection of the major and minor cutting edges. The major cutting edge has a non-linear, variable slope with respect to a central axis A2 passing through the two minor side surfaces of the cutting insert.

Abstract: An indexable cutting insert having a triangular shape includes three sides and three cutting corners. A first planar surface and a second, parallel planar surface connects the three sides. In one embodiment, three major cutting edges are formed at an intersection between a respective side and the first planar surface. In another aspect, six major cutting edges are formed at an intersection between a respective side and the planar surfaces. In another aspect six major right-handed cutting edges and six major left-handed cutting edges are formed at an intersection between the sides and the first and second planar surfaces.

Abstract: A cutting tool includes a pocket with a top wall, a bottom wall, a side wall and a rear wall. The cutting tool has a wedge clamping system that includes an insert cartridge and a clamp wedge. The insert cartridge includes a recess that interacts with a protrusion on the clamp wedge in such a way that the clamp wedge exerts a force vector in an axial direction when the clamp wedge is threaded into the pocket, thereby reducing deflection of an adjacent pocket of the cutting tool when the cutting tool is placed in a locked condition.

Abstract: An indexable cutting insert includes a top surface, a bottom surface, a plurality of peripheral side surfaces, and a plurality of cutting edges formed at an intersection between said top surface and plurality of side surfaces. A plurality of triangular-shaped serrations are positioned along the cutting edges, each serration comprising an apex and a pair of side surfaces that meet at a vertex. The serrations provide the cutting edges with both a positive axial rake angle and a negative axial rake angle, thereby reducing delamination when machining a composite material.

Abstract: A cutting tool includes a pocket with a top wall, a bottom wall, a first side wall for engaging an insert cartridge, a second side wall, a first rear wall, and a second rear wall. The top wall and the bottom wall are formed at a negative angle with respect to each other to provide a closed pocket design that resists centrifugal forces when the insert cartridge and the clamp wedge are in a locked condition during a cutting operation.

Abstract: A combination of a cutting insert and a shim. The cutting insert and shim have two opposing end surfaces, two identical opposing major side surfaces and two identical opposing minor side surfaces. Each end surface of the insert has a shim abutment surface for contacting the shim. One end surface of the shim has an insert abutment surface for contacting the insert. The abutment surfaces contact each other along an entire length of the cutting insert and shim so as to help distribute the loads encountered in the cutting operation, as well as provide protection of the insert pocket in case of insert failure.

Abstract: The invention relates to a cassette for a milling cutter having a cutter carrier and a clamping part, which together constitute a generally rectangular cassette, the cutter carrier and the clamping part being loosely placed on each other and together delimiting a fastening opening for a fastening screw by means of which the cassette can be fastened in a receiver of a milling cutter, the cutter carrier having a seat for a cutting insert. The invention additionally relates to a milling cutter having at least one receiver for a cassette and having at least one such cassette. A gap, S, between the cutter carrier and the clamping part is located below the cutting tip of the cutting insert to prevent chips from being lodged in the gap, S.

Abstract: A round cutting insert with an anti-rotation feature. The round cutting insert includes a plurality of projections formed on a first surface and another plurality of projections formed on an opposing surface. The round cutting insert is reversible and indexable. The round cutting insert is removably received in an insert receiving pocket in a tool body wherein the insert receiving pocket includes a plurality of dimples for receiving one of the plurality of first projections or the plurality of second projections. This arrangement prevents rotation of the round cutting insert while mounted in the insert receiving pocket.

Abstract: A combination of a cutting insert and a shim. The cutting insert and shim have two opposing end surfaces with two identical opposing major side surfaces and two identical opposing minor side surfaces extending between the minor side surfaces.

One end surface of the shim has two raised abutment members, each having an insert abutment surface for contacting the insert. The abutment surfaces contact each other in an area where high cutting forces occur so as to help distribute the loads encountered in the cutting operation, as well as provide protection of the insert pocket in case of insert failure.
