摘要： A cutting insert (20) has a cutting edge (26) formed at an intersection of a rake surface (28) and a relief surface (30), with a chip-control arrangement (22) located at the rake surface (28). The chip-control arrangement (22) includes a plurality of recesses (50, 74) that extend downwardly into the rake surface (28) and a plurality of projections (52, 72) that extend upwardly from the rake surface (28). The plurality of recesses (50, 74) follow a pattern of increasing depth in a rearward direction (DR) from the forward portion (25) of the cutting edge (26). The plurality of projections (52, 72) follow a pattern of increasing height in a rearward direction (DR) from the forward portion (25) of the cutting edge (26).

摘要： A cutting insert according to an embodiment of the present invention includes an insert body including an upper surface, a lower surface, a side surface connected to each of the upper surface and the lower surface, and a cutting edge located at an intersection of the upper surface and the side surface. The insert body is divided into a cutting section and a fixing section. A region of the upper surface located at the cutting section includes a rake surface which is located further inward than the cutting edge and is inclined as going inward at an inclination angle α1 with respect to a reference plane perpendicular to a central axis, and a plurality of protruded parts arranged along the cutting edge. Each of the plurality of protruded parts includes a first surface which is inclined as going inward at an inclination angle α4a with respect to the reference plane and has a larger width as going inward in a top view. The inclination angles α1 and α4a satisfy a relationship of α1>α4a.

摘要： The invention relates to a polygonal turning insert having a cutting edge, which includes three part edges, viz. a nose edge (12) situated in a corner and two main edges (13) converging toward the same, as well as chip-guiding flank surfaces for each one of the part edges, viz. a primary flank surface (21) situated behind the nose edge (12) along a bisector (B) between the main edges (13), as well as a pair of secondary flank surfaces situated inside the respective main edge. According to the invention, the primary flank surface (21) is convexly arched and delimited by an arched lower boundary line (22), which has an apex point (AP) facing the nose edge and being situated along the bisector (B) and includes two mirror-symmetrical arc part lines, which extend from the apex point to a pair of opposite end points situated along a straight reference line (RL) that intersects the bisector at a right angle in a middle point (MP) between the end points, the distance between the midpoint and the individual end point being greater than the distance between the midpoint and the apex point. In addition, the angle of inclination of the primary flank surface (21) in arbitrary vertical sections through the midpoint decreases from a greatest value in a section along the bisector (B) to a smallest value in a section along the reference line (RL).

摘要： A cutting insert is provided which enables a reduction in cutting resistance and stable process. The insert includes a chip breaker groove formed inside corner cutting edges and a raised portion. The raised portion includes a top surface, a front raised surface, and side raised surfaces. The top surface crosses the front raised surface and each of the side raised surfaces. A first intersecting portion at which the front raised surface and the top surface intersects with each other is linearly extended. A second intersecting portion at which each of the side raised surfaces and the top surface intersect with each other is extended from a corresponding one of opposite sides of the first intersecting portion so that a distance from the corresponding side cutting edge increases gradually with a distance from the corner cutting edge. The front raised surface and the side raised surfaces are curved convexly outward.

摘要： The invention relates to a cutting insert to be turned in a direction of delivery of the tool, which is predefined in a fixed manner relative to the axis of the workpiece. Said cutting insert comprises a main blade for comparatively rough cuts and a simultaneously working finishing blade. According to figure 3, which shows a cutting edge as a section BB of a cutting insert having a symmetrical direction (9), the inventive cutting insert is provided with sectors A and B which are bent differently relative to each other and have a different length, and a knob (70) which is elongate relative to the position and direction of stretching (10). A workpiece having low roughness is obtained even at a relatively great depth of cut and at great tool advance during turning with a cutting insert that is embodied in said manner.
