    摘要: A thread cutting insert comprises parallel side surfaces (12,13) and two mutually adjacent edge surfaces (15,16), which are provided with cutting teeth (20-29) and extend between the side surfaces (12,13). For purposes of minimizing the amount of material ground away from a blank during manufacture of the cutting insert this material comprises surface portion (46-54) separated from each other by the cutting teeth.

    摘要: There is provided a cutting insert for threading work for achieving high shape accuracy of a screw to be processed, as well as low costs. Therefore in the cutting insert for threading work, a plurality of mountain-shaped cutting edges are formed in a cross ridge line portion between a rake face (2) formed on an upper face and flanks formed in a side face as viewed from a side of the rake face (2), wherein the cutting edge comprises at least one finishing cutting edge (6a) for transferring a shape of a screw, and at least one roughing cutting edge (6b)formed in a mountain shape smaller than that of the finishing cutting edge (6a) as viewed from a side of the rake face (2). A flank (4a) of the finishing cutting edge (6a) includes a first flank (5a), and a second flank (5b) having a clearance angle larger than that of the first flank (5a) as viewed in a normal direction of the cutting edge, wherein the finishing cutting edge (6a), the first flank (5a), and the second flank (5b) are sequentially provided in that order.

    摘要: The present invention relates to cutting tools with cutting inserts and, more particularly, to cutting inserts having adjusted cutting edges. The cutting insert (25) comprises a virtual clearance surface (37) that is one of substantially flat and planar and substantially frustoconical. The virtual clearance surface forms a non- zero angle with a perpendicular to a virtual plane of a top surface (39) of the insert. A first virtual cutting edge (41) is disposed above the virtual clearance surface (37). All points on the first virtual cutting edge (41) are disposed at the plane of the top surface (39). An adjusted clearance surface (45) differs from the virtual clearance surface (37) and forms the non-zero angle with the perpendicular to the plane of the top surface (39). An adjusted cutting edge (47) above the adjusted clearance surface (45), at least some but fewer than all points on the adjusted cutting edge (47) are disposed at different distances from the plane of the top surface (39). A profile of the adjusted cutting edge (47) viewed in the direction of the perpendicular to the plane of the top surface (39) corresponds to a profile of the first virtual cutting edge (41). The present invention also relates to a cutting tool.

    摘要: The invention relates to a polygonal indexable insert which comprises cutting edges (2) which extend in a straight or curved manner on a plane which is perpendicular to the bearing surface, said cutting edges tilting from cutting corners (3) at an acute angle to alternating successive cutting edges (4) at an obtuse angle. The cutting edges (2) have an initially tiling cutting face (6) which mounts with a rear area (7). The rear area (7) forms an intersection curve (8) with a centre part (18) of the indexable insert. The intersection curve (8) has a space (a) from the starting point (15) of the associated cutting edge (2) in the region of the cutting corners (3), respectively, in the intersection point (9) with the bisecting line (10), and a space (b) from the end point (16) of the associated cutting edge (2), which is greater than the space (a), in the region of the cutting corners (4) in the intersection point thereof (11) with the bisecting line (12).
