Definitions

  • the one-sided cutting insert (insert) of the present disclosure which is not limited to the present disclosure, has a quadrangular prism shape extending from the front end toward the rear end along the central axis, and is positioned on the side of the front end, and a cutting edge located at the front end. and a main body positioned closer to the rear end than the cutting portion.
  • the main body portion has an upper surface having a V-shaped first groove extending along the central axis, and a V-shaped second groove located on the opposite side of the upper surface and extending along the central axis. a bottom surface having grooves.
  • the first groove has a first region located on the rear end side and a second region located on the tip side of the first region.
  • the opening angle of the first groove in the first region is smaller than the opening angle of the first groove in the second region.
  • the opening angle of the second groove is constant in the direction along the central axis.
  • the first groove 13 may extend to the end of the body portion 3 on the tip 1a side, or may be separated from the end of the body portion 3 on the tip 1a side. Similarly, the first groove 13 may extend to the end of the body portion 3 on the rear end 1b side, or may be separated from the end of the body portion 3 on the rear end 1b side.
  • the second groove 15 may extend to the end of the body portion 3 on the tip 1a side, or may be separated from the end of the body portion 3 on the tip 1a side. Similarly, the second groove 15 may extend to the end of the body portion 3 on the rear end 1b side, or may be separated from the end of the body portion 3 on the rear end 1b side.
  • the first groove 13 and the second groove 15 may be used for the purpose of improving positioning accuracy when inserting the insert 1 into the holder. Also, the first groove 13 and the second groove 15 may be used for the purpose of improving the binding force when fixing the insert 1 to the holder.
  • the upper jaw of the holder has a projection that abuts against the first groove 13
  • the lower jaw of the holder has a projection that abuts against the second groove 15, thereby improving the positioning accuracy and the restraining force described above.
  • the opening angles ⁇ 1 in these regions may differ from each other.
  • the opening angle ⁇ 1 of the first groove 13 in the first region 17 is the opening angle ⁇ 11
  • the opening angle ⁇ 1 of the first groove 13 in the second region 19 is the opening angle ⁇ 12.
  • the opening angle ⁇ 11 may be smaller than the opening angle ⁇ 12. In such a case, for the following reasons, it is easy to attach/detach to/from the holder, but it is likely to be stably restrained by the holder.
  • the insert 1 has a first cutting portion 5a and a second cutting portion 5b as in a non-limiting example shown in FIG. 5 will be described below.
  • the third region 27 makes it difficult for the insert 1 to be misaligned in the lateral direction.
  • the cermet may be a sintered composite material in which a metal is combined with a ceramic component.
  • An example of a cermet may be a titanium compound based on titanium carbide (TiC) or titanium nitride (TiN).
  • TiC titanium carbide
  • TiN titanium nitride
  • the material of the insert 1 is not limited to the above composition.
  • the surface of the insert 1 may be coated with a coating using chemical vapor deposition (CVD) or physical vapor deposition (PVD) methods.
  • Coating compositions may include titanium carbide (TiC), titanium nitride (TiN), titanium carbonitride (TiCN), alumina (Al 2 O 3 ), and the like.
  • the cutting work 203 is produced by cutting the work material 201 .
  • the manufacturing method of the cut workpiece 203 in the embodiment includes the following steps. i.e. (1) a step of rotating the work material 201; (2) a step of contacting the rotating work material 201 with the cutting tool 101 represented by the above embodiment; (3) separating the cutting tool 101 from the work material 201; Prepare.
  • the cutting tool 101 In each process, by moving the cutting tool 101, the cutting tool 101 is in contact with the work material 201, or the cutting tool 101 is separated from the work material 201, but of course it is not limited to such a form. .
