Definitions
- the present invention relates to a cutting insert and a cutting tool including the cutting insert.
- an optimum cutting tool is selected according to the type of processing and the material of the workpiece.
- One of the important factors in selecting a cutting tool is the cutting edge shape of the cutting insert that is actually involved in cutting the workpiece. For example, when machining a pocket shape of a mold, a cutting insert having a substantially arc-shaped cutting edge is used (see Patent Document 1). For other machining of the mold, the shape of the cutting edge is a straight line. A shaped cutting insert is used (see Patent Document 2).
- the cutting angle gradually increases as the cutting depth increases.
- the cutting angle is an angle formed by a tangent line of the cutting edge and a reference plane orthogonal to the central axis of the tool body.
- the cutting thickness also increases.
- the cutting resistance applied to the cutting boundary which is the boundary between the part involved in cutting and the part not involved in cutting, increases.
- This increase in cutting resistance shortens the life of the cutting edge until the cutting edge becomes worn and becomes unusable, and increases the possibility of causing a sudden loss of the cutting boundary.
- the cutting depth is generally suppressed to about 1.0 mm, and there is a problem that the machining efficiency is relatively low.
- the cutting edge is a linear cutting insert
- the cutting thickness accompanying the increase in the cutting depth does not increase, but the cutting resistance applied to the cutting boundary when the cutting depth is small is the arc-shaped cutting edge. It tends to be larger than For this reason, in a cutting insert having a straight cutting edge, there is a possibility that the cutting edge may be suddenly lost at the moment of cutting into the workpiece.
- the present invention has been made in view of the above-described problems, and an object of the present invention is to provide a cutting insert including a cutting blade capable of suppressing an increase in cutting resistance applied to a cutting boundary as the cutting depth increases, and the cutting thereof.
- the object is to provide a cutting tool with a fixed insert.

- the upper cutting edge and the lower cutting edge are plane-symmetric with respect to a plane that passes between the upper surface and the lower surface and is orthogonal to the central axis of the cutting insert.
- the said side surface is comprised by the curved surface or uneven surface according to the shape of the said cutting blade, and the said side surface is fixed to the said attachment seat.
- the cutting angle portion of the cutting edge is formed of a curved curve that is concavely curved.
- the cutting edge decreasing cutting edge portion of the cutting edge is composed of a plurality of line segments.
- the rake face is formed on a first side surface extending between the upper surface and the lower surface, the flank surface extends between the upper surface and the lower surface, and the first surface
- the cutting edge is formed at the intersection of the first side surface and the second side surface.
- the flank includes an engaging groove that engages with an engaging protrusion formed on a mounting seat of the cutting tool body.
- a cutting tool includes a cutting insert having a rake face, a flank face, and a cutting blade formed at an intersection of the rake face and the flank face, and the cutting insert is detachably mounted.
- a cutting tool main body having a mounting seat, and the cutting blade has at least a part of a tangent at a point on the cutting blade and the cutting tool when the cutting insert is mounted on the mounting seat.
- the present invention is characterized by having a cutting angle decreasing cutting edge portion in which a cutting angle formed by a reference plane orthogonal to the central axis of the main body gradually decreases in a direction in which the cutting depth of the cutting blade increases.
- an engagement groove is formed on the flank, and the mounting seat of the cutting tool body has an engagement protrusion that engages with the engagement groove.

- the cutting tool 20 shown in FIGS. 1 and 2 is a high-feed cutter, and includes a cutting tool body 21 and a plurality of cutting inserts 10.
- the cutting tool main body 21 of the cutting tool 20 has a substantially cylindrical shape as shown in FIG. 4 and the like, and a connecting hole 23 for connecting to a machine tool is provided at the center of the cutting tool main body 21 from the rear end of the cutting tool main body 21. It is provided penetrating to the part. Further, the cutting tool main body 21 has a plurality of mounting seats 22 formed at equal intervals in the circumferential direction around the central axis J. A cutting insert 10 described later is attached to each of the plurality of mounting seats 22. The cutting insert 10 is fixed to the cutting tool body 21 with bolts BT. A chip pocket 24 is formed in front of the rotation direction R of the mounting seat 22 formed at the tip of the cutting tool body 21 to facilitate the generation, storage and discharge of chips. The structure of the mounting seat 22 will be described later.
- the cutting tool 20 is mounted on a main shaft of a machine tool such as a machining center, and is rotated about its central axis J. Then, the workpiece located on the reference plane orthogonal to the central axis J of the cutting tool 20 is cut by the cutting insert 10.
- the mounting seat 22 is cut out so that a part of the tip of the cutting tool body 21 has substantially the same shape as the lower surface of the cutting insert 10.
- the notch depth D10 is substantially equal to the thickness of the cutting insert 10, as shown in FIG.
- the mounting seat 22 is formed such that the cutting insert 10 is inclined about 10 ° with respect to a reference plane perpendicular to the central axis J.
- the cutting insert 10 is a substantially square plate made of cemented carbide, for inserting a bolt BT at the center and fixing the cutting insert 10 to the cutting tool body 21.
- a through hole 16 is formed.
- a rake face 11 on which chips are rubbed is formed on the upper and lower surfaces of the cutting insert 10, and a flank face 12 for avoiding contact with the workpiece is formed on a side surface perpendicular to the rake face 11.
- a cutting edge 13 for cutting the workpiece is formed at the intersection where the rake face 11 and the flank 12 intersect.
- the rake face 11 includes a flat surface portion 11a formed on the outer peripheral edge portion, and an inclined surface portion 11b that is inclined from the flat surface portion 11a toward the middle depth portion of the rake face 11. For this reason, even if the cutting insert 10 is arranged at a negative angle with respect to the direction (axial) of the central axis J of the cutting tool 20, the rake angle is increased to the plus side by the amount of the inclination angle of the inclined surface portion 11b. Since it is returned, the reduction in sharpness can be suppressed.
- a negative angle in the axial direction means that the rake face 11 is inclined in the rotational direction of the cutting tool 20, and a positive angle in the axial direction means that the rake face 11 is in the rotational direction of the cutting tool 20. Means a state inclined in the opposite direction.
- FIG. 8 shows the configuration of the cutting blade 13 of the cutting insert 10 mounted on the mounting seat 22 of the cutting tool body 21.
- the cutting blade 13 is a portion that first bites into the workpiece during cutting, is formed in a straight line, and is defined by a wiping blade 13a defined by points P1 to P2, and a point P2 subsequent thereto. It includes a tip cutting edge 13b defined by the point P3 and a cutting angle reducing cutting part 13c formed by a curved curve that is curved from the point P3 to the point P4.
- the cutting angle ⁇ is an angle formed by a tangent at a point on the cutting edge 13 and the reference plane BF.
- the cutting angle in this specification is a parameter based on industrial standards such as JIS. That is, as shown in FIG. 8, it is an angle formed by a tangent at a point on the cutting edge 13 and the reference plane BF.
- the cutting angle ⁇ at the tip cutting edge 13b gradually increases in the direction in which the cutting depth D of the cutting blade 13 increases.
- the cutting angle ⁇ is ⁇ 1, which is the maximum value.
- the cutting depth D of the cutting blade 13 is further decreased from D1, that is, gradually decreases from the P3 point toward the P4 point, and takes a minimum value at the P4 point.
- the cutting angle decreasing cutting edge portion 13c By making the cutting angle decreasing cutting edge portion 13c into such a shape, when the cutting angle decreasing cutting edge portion 13c is cut into the workpiece, the cutting angle ⁇ is continuously increased as the cutting depth D increases thereafter. It gets smaller. Along with this, the chip cutting thickness is also reduced, so that the cutting resistance applied to the incision boundary portion is also reduced, and wear of this portion is suppressed.
- the cutting angle decreasing cutting edge portions 13c are formed at four locations on each of the cutting edges 13 on the upper surface and the lower surface of the cutting insert 10. Therefore, the upper cutting edge 13 and the lower cutting edge 13 pass through the middle between the upper surface and the lower surface and are plane-symmetric with respect to a plane perpendicular to the central axis K of the cutting insert.

- the groove 14 is in close contact with the inclined surface on the rear side in the rotation direction. Even if a cutting resistance is applied to the outside of the cutting insert 10 during cutting because the engaging protrusion 26 and the engaging groove 14 are fitted, the engaging protrusion 26 presses the cutting insert 10 toward the mounting seat 22. Since it fixes, the seating stability of the cutting insert 10 increases.
- the cross-sectional shape of the engaging groove 14 and the cross-sectional shape of the engaging protrusion 26 are not limited to those described above.
- the shape of the engaging protrusion 26A can be made into a V shape corresponding to the engaging groove 14A so that the engaging protrusion 26A is completely fitted into the engaging groove 14A. By doing in this way, the seating stability of cutting insert 10A increases more.
