摘要： A cutting insert has opposing first and second end surfaces, and a peripheral side surface (connecting the end surfaces. A central axis penetrates the two end surfaces. The peripheral sure surface includes an outwardly inclined first side surface part related to a major cutting edge and a second side surface part related to a minor cutting edge. The outwardly inclined first side surface part gradually extends outward from the cutting insert, heading from the first end surface to the second end surface. When a second virtual plane, which is substantially perpendicular to the central axis and passes through the major cutting edge, is defined, an inwardly inclined part, on a back side of the cutting edge, of the second end surface is inclined so as to become more distant from the second virtual plane, heading from the outwardly inclined first side surface part to the central axis.

Each milling insert has a plurality of tangentially spaced-apart and alternately usable cutting edges, which individually fall archedly from a first end, situated closest to an upper reference plane, to a lowest point, from which it again rises toward a second end. A reinforcing chamfer surface included in the cutting edge is formed with an increasing width in a direction from the first end of the cutting edge toward the second end.

摘要： A high-speed milling cutter has a tool parent body and one or more plate-shaped cutting inserts with a convex, approximately arc-shaped cutting edge. The insert(s) is/are fastened in an insert seat of the tool parent body. Mating elements with mutual contact surfaces for absorbing the centrifugal forces occurring during use are provided in each case between insert seat and cutting insert. The contact surface of the first mating element is designed in the shape of a circular arc, approximately concentrically to the cutting edge. The contact surface of the second mating element is likewise designed in the shape of a circular arc, approximately concentrically to the cutting edge, or consists of at least two contact zones which lie on an imaginary circular arc, approximately concentrically to the cutting edge, the contact surface or the imaginary circular arc coinciding with the contact surface of the first mating element.

摘要： An anti-rotation mounting mechanism is provided between an indexable insert and an insert-receiving pocket in the body of a machine tool, such as a milling cutter. The mechanism includes a plurality of curved stop surfaces uniformly disposed around the side surface of the insert, a portion of which is obliquely oriented with respect to the side surface of the insert, and at least one anti-rotation surface in the pocket of the tool body having a shape substantially complementary to that of the stop surfaces for forming an interference joint between the pocket and the insert. Both the stop surfaces and the anti-rotation surface are substantially defined by partial radius curves such that either a broad, line-type or lenticular contact between the anti-rotation surface and the obliquely oriented portion of one of the stop surfaces is achieved. The mechanism effectively prevents rotation between the insert and pocket without the formation of point-type, localized stresses which can chip or break the insert.
