摘要： Described is an end mill with four straight front cutting edges arranged on a front side and a corresponding number of circumferential cutting edges that each emanate from the outer nose of the front cutting edges and are separated from each other by flutes. One of the front cutting edges passes over into a second cutting edge via a free surface intersecting line. The additional front cutting edges lying between the latter in the cutting direction are offset relative to each other by a first angular pitch of 180°, and end before the middle. So that the end mill can be used in an especially advantageous manner for incorporating dimensionally and positionally precise pilot holes or chamfering curved work piece surfaces, the first front cutting edge is offset relative to the second front cutting edge in the cutting direction by a second angular pitch ranging between 173° and 177°, preferably between 174° and 176°, wherein the first front cutting edge is offset relative to the next additional front cutting edge in the cutting direction by a third angular pitch ranging between 90° and 94°, preferably between 91° and 93°.

摘要： End mills are disclosed which may be made monolithically of ceramic or other materials. The cutting portions of the end mills have lengths of cut that are no more than twice their cutting diameters and cores which are at least 0.7 times their cutting diameters. Their axial blades have cutting edges with negative radial rake and are separated by helical flutes. Their cutting ends have negative axial rake and are gashed ahead of center and have radial cutting edges with negative rake. Such end mills also have radiused corners and gashes transitioning from radial to axial at a flute. Methods of milling materials using such ceramic end mills are also disclosed.

摘要： A cutting tool, such as a milling cutter, includes a tool body and a plurality of pockets for receiving cutting inserts. Each pocket includes a bottom support surface, an radial support surface, an axial support surface, a first corner relief between the bottom support surface and the radial support surface, and a first stress relief formed in the first corner relief at one end of the pocket. The first stress relief is formed at an angle with respect to a plane parallel to the radial support surface. The first stress relief reduces a tensile stress of the cutting tool during a machining operation. A second and third stress relief may be formed in the first corner relief and/or in a second corner relief.

摘要： An end mill having a plurality of teeth configured for both roughing and semi-finishing applications, the teeth being alternated with a plurality of flutes. At least one tooth of the plurality of cutting teeth is a serrated tooth formed with serrations along a relief surface thereof and at least one other tooth is free of serrations. Each tooth of the plurality of cutting teeth includes an actual internal cutting angle formed at an intersection of a rake cutting sub-surface and a relief surface. The actual internal cutting angle of each tooth has a greater value than an imaginary internal cutting angle formed at an intersection of imaginary extension lines of a rake recessed sub-surface and a relief surface of the same tooth.

摘要： A corner radius end mill includes a blended gash extending along a cutting edge. The blended gash is formed in a corner sector of the end mill. The corner sector has a first half-sector and a second half-sector defined on opposite sides of an imaginary bisection line of the corner sector, the first and second half-sectors subtending equal angles about the imaginary bisection line. The blended gash extends from a first extremity and blends an end gash surface and flute rake surface of the corner radius end mill. The blended gash is spaced from a radial tangent point by a predetermined distance, and extends to a second extremity which is spaced apart from the axial line and the second half-sector.
