In another embodiment, six major cutting edges are formed at an intersection between a respective side and the planar surfaces. In another embodiment, 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
