Abstract: A compression milling cutter includes a shank and a front cutting portion that terminates at a leading end of the milling cutter. The front cutting portion has a first circumferential row of one or more insert receiving pockets proximate a leading end of the milling cutter, and a second circumferential row of one or more insert receiving pockets, each insert receiving pocket configured to receive a respective indexable cutting insert. The cutting insert mounted in the first circumferential row has a positive axial rake angle, A, and the indexable cutting insert mounted in an insert pocket of the second circumferential row has a negative axial rake angle, B. Because of the different axial rake angles, chips generated during a machining operation flow in opposite directions, thereby creating a compression zone disposed between the first and second circumferential rows. This compression zone replicates the cutting action of a solid end mill, particularly when machining fiber reinforced plastic materials.

Abstract: A rotary cutting tool (20) has a cutting body (22) and a plurality of cutting inserts, including a first insert (24) removably secured in a first pocket and a second insert (26) removably secured in a second pocket. The first pocket opens out at a forward end surface of the cutting body, having a seat surface with an axial support wall (58) transverse thereto, and the second pocket is located axially rearward of the first pocket. The first insert has opposing front and back end surfaces, with a peripheral side surface extending therebetween which is in contact with the seat surface and the axial support wall. A first major cutting edge (42) of the first insert axially overlaps with a second major cutting edge (52) of the second insert, and in a side view of the cutting tool, a raised shoulder surface adjacent the axial support wall is at least partially obscured by the second insert.

Abstract: End mills having vibration reduction elements are disclosed. In one embodiment, an end mill includes a plurality of helical lands that are oriented in a twist direction around a centerline axis, where the helical lands extend to an axial end. The end mill also includes a cutting edge positioned along each of the helical lands. The cutting edge includes a flute portion, a corner portion, and an end cutting portion. The end mill further includes a margin that extends away from the cutting edge in a direction counter to the twist direction. The margin extends along the cutting edge along at least a portion of the flute portion and at least a portion of the corner portion.
