摘要： A cutting edge is formed at a ridge between an upper surface and a side surface. In the side surface, a plurality of grooves are formed so as to extend from the side surface to the upper surface to divide the cutting edge, and the clearance angles within these grooves are formed so as to increase from one end of the cutting edge toward the other end of the cutting edge. This achieves a cutting insert having small cutting force and excellent cutting performance. Among the plurality of grooves, the groove nearest to the one end of the cutting edge has preferably a width increasing from the upper surface of the cutting insert toward the lower surface.

摘要： A milling tool with an axis of rotation D has a tool shank and a cutter region. The cutter region has a planar cutting edge running approximately perpendicularly to the axis of rotation D and merges peripherally into a main cutting edge and centrally into a secondary cutting edge. The secondary cutting edge is offset rearwardly from the planar cutting edge in the direction of the axis of rotation D. The transitional zone between the planar cutting edge and the secondary cutting edge has a notch produced as a cutting edge portion. The rearmost point of this notch, as seen in an end view in the direction of the axis of rotation D, lies behind the forward-most point of the secondary cutting edge, the angle α between the planar cutting edge and the adjoining portion of the notch lying in the range of 90° to 175°, and the angle β between the planar cutting edge and that portion of the notch adjoining the secondary cutting edge lying in the range of 3° to 90°. The angle γ between that portion of the notch adjoining the secondary cutting edge and the secondary cutting edge lies in the range of 90° to 177°.

摘要： Cutter plates (19) with an approximately cube-shaped base body have been created, in particular for finish-milling of a crankshaft (5). At the edge of its cover surface, the base body is provided with a hump or protrusion, which can be embodied rib- or strip-shaped, has a cutting edge each on its front and back and adjoins the neighboring lateral surface. This cutting edge is a component of the main cutting edge (33) adjoining the cover surface. A corresponding protrusion (29) is provided on the lower end of the lateral surface (27) and adjoins the end of the cover surface (22) remote from the protrusion (28). In this case the lateral surface (27) is preferably inclined in such a way that it terminates flush with the protrusion (29) without forming a concave surface area with it. A corresponding milling tool can be completely and exclusively equipped with such cutter plates and can process in one work step the cylinder surface (14) of a crank pin, corresponding relief grooves (15, 16) toward both edges of the cylinder surface (14), and adjoining end faces (17, 18). In the course of this a higher number of cutting edges is provided in the area of the relief grooves (15, 16), than for the cylinder surface (14). Thus a particularly high degree of processing quality is achieved in the area of the relief grooves (15, 16) in particular. The relief grooves (15, 16) are designed in a production-friendly manner without trade-offs regarding processing quality and precision.

摘要： A cutting insert for mounting on a milling cutter has a generally quadrangular shape with top and bottom surfaces, a pair of opposite first side surfaces intersecting the top surface at first cutting edges and a pair of opposite second side surfaces intersecting the top surface at second edges. Each second edge has a front cutting portion oriented substantially transversely to an adjacent first cutting edge and meeting therewith via a cutting corner. Each of the first and second side surfaces has upper and lower sections adjacent respective top and bottom surfaces, which sections have leading portions adjacent their associated cutting corner and trailing portions remote therefrom. The trailing portion of the lower section of each second side surface is at least slightly inwardly depressed relative to the leading portion of the lower section and is substantially inwardly depressed relative to the associated trailing portion of the upper section of the second side surface. The trailing portions of the lower and upper sections merge via a transition surface oriented transversely thereto.

摘要： A cutting insert is produced by form-pressing and sintering of powder. The insert comprises a top chip surface, a bottom surface, and at least one edge surface extending between the top and bottom surfaces. The edge surface includes at least one relief surface portion which intersects the top surface at an acute angle to form therewith a cutting edge. A grinding operation is performed on the edge surface, but only along a lower portion thereof disposed below the relief surface portion, i.e., only along an area which is to be placed against a locating surface of a machine tool during a cutting operation.
