- the rake angle ⁇ b of the second rake face 24b is larger than the rake angle ⁇ a of the first rake face 24a. Therefore, the rake face 24 is convex so as to protrude toward the upper face 18 as a whole.
- the rake face 24 is formed so that the rake angle ⁇ b of the second rake face 24b is larger than the rake angle ⁇ a of the first rake face 24a.

- the rake angle ⁇ b of the second rake face is not less than 15 ° and not more than 35 °, and is set to approximately 30 ° in the present embodiment.
- the first rake face 24a first affects the cutting of the work material.
- the rake angle ⁇ a of the first rake face is less than 10 °
- the effect of reducing the cutting resistance by thinning the chips is insufficient regardless of the rake angle ⁇ b of the second rake face.
- the rake angle ⁇ a of the first rake face exceeds 25 °
- the cutting edge strength decreases regardless of the rake angle ⁇ b of the second rake face. Therefore, for example, in the cutting of carbon steel, chipping and chipping are likely to occur.
- the angle difference between the first rake face and the second rake face is small. .
- the thickness of the cutting insert around the cutting edge is insufficient. May be largely lost.
- the horizontal distance Wa from the cutting edge 22 to the end portion of the first rake face 24a, that is, the rising wall side end 24c is smaller than the radius of curvature of the arcuate cutting edge 22a provided in the corner portion 18c.
- the distance Wa is defined in a direction perpendicular to the cutting edge 22 and perpendicular to the axis A as seen from the end face side, as shown in FIGS.
- the distance Wa is desirably 0.05 mm or more and 0.30 mm or less, and more preferably 0.05 mm or more and 0.20 mm or less.
- the distance Wa is set to about 0.12 mm over the entire circumference of the cutting edge 22.
- the distance Wa need not be constant. That is, the distance Wa may be the above value in the vicinity of the corner portion, and can be arbitrarily set in other portions.
- the horizontal distance Wb from the cutting edge 22 to the terminal end of the second rake face 46, that is, the rising wall side end 24d, is viewed from the end face side, as shown in FIGS. It is defined in a direction perpendicular to the cutting edge 22 and perpendicular to the axis A.
- the distance Wb is preferably 0.20 mm or more and 0.70 mm or less, and is set to about 0.4 mm in this embodiment.
- a chip breaker raised portion 32 is formed inside the pair of arcuate cutting edges 22a.
- the rising wall surface 32 a of the chip breaker raised portion 32 extends so as to form a recess 34 in the upper surface 18 together with the rake face 24.
- the rising wall surface 32a is a rising surface that rises from the bottommost portion 34a of the concave portion 34, and extends so as to rise upward as the distance from the rake face 24 starts from the coupling portion 32b with the bottommost portion 34a of the concave portion 34.
- the rising wall surface 32a is a flat surface, and is inclined so as to move away from the central plane M as it gradually moves away from the arcuate cutting edge 22a and the linear cutting edge 22b.
- the chip breaker raised portion 32 has a top surface 32c connected to the rising wall surface 32a and extending substantially parallel to the central plane M in addition to the rising wall surface 32a.
- the top surface 32c is a substantially flat surface.
- the top surface 32 c is formed to be higher than the cutting edge 22. This means that when a plane perpendicular to the axis A and passing through the cutting edge 22 is defined, this plane extends so as to cross the rising wall surface 32a.
- the inclination angle ⁇ of the rising wall surface 32a with respect to the second plane, that is, the horizontal plane is larger than the rake angle ⁇ b of the second rake face 24b.
- the inclination angle ⁇ is desirably set to 30 ° or more and 60 ° or less, and is set to approximately 45 ° in the present embodiment.
- the inclination angle ⁇ is less than 30 °, the chips at the chip breaker bulge portion 32 are difficult to undergo the desired curl deformation, and as a result, the chips can be thick.
- the inclination angle ⁇ exceeds 60 °, the collision between the chip breaker and the chips becomes too strong, and the cutting resistance may increase. Therefore, in this case, the frequency of occurrence of chatter is increased, and the frequency of generation of thick chips can be increased.
- the rising wall surface 32 a is an extension defined so as to extend the first rake face 24 a, that is, the first region, on a plane defined to be orthogonal to the cutting edge 22, that is, in a cross section orthogonal to the cutting edge 22.
- the surface S1 or the extension line L1 is formed in relation to the rake face 24 so as to be divided into two regions across the rising wall surface 32a. While this relationship is maintained, the rising wall surface 32a is connected to the bottom surface of the groove, that is, the bottom surface of the recess, extending to the bottom 34a of the recess 34 that is a chip breaker groove.
- the bottom surface of the groove is closest to the central plane M in the recess 34, and extends between the rake face 24 and the rising wall surface 32a, as shown in FIGS. Therefore, as shown in FIGS. 4 and 5, the rising portion where the rising wall surface 32a starts to rise from the groove bottom surface, that is, the coupling portion 32b is lower than the extension surface S1 or the extension line L1 of the first rake face 24a, that is, the center. Located on the plane M side (located on the seating surface side) and higher than the extension surface S2 or extension line L2 of the second rake face 24b, that is, on the side away from the center plane M (on the upper surface 12 side).
- the horizontal distance Wc from the cutting edge 22 to the rising portion of the rising wall surface 32a is orthogonal to the cutting edge 22 as viewed from the end face side, as shown in FIGS. And defined in a direction perpendicular to the axis A.
- the distance Wc is preferably 0.70 mm or more and 1.50 mm or less, and is also set in the range in this embodiment.
- the rising wall surface 32a is raised from the bottom surface of the substantially horizontal and small groove extending inward from the terminal end portion 24d of the second rake face 24b.
- This groove bottom surface can be omitted.
- the rising wall surface 32a is continuous with the second rake face 24b so as to protrude directly from the end portion 24d of the second rake face 24b. Therefore, in this case, the coupling portion 32b which is the rising portion of the rising wall surface 32a is on the extended surface S2 obtained by extending the second rake face 24b.
- the top surface 32c of the chip breaker raised portion 32 extends at the same level as the boss surface 30 described above, and is configured as a substantially flat surface. Such a configuration is particularly effective when the cutting edges 22 are formed on both end faces 12 and 14. In the case of a cutting insert that selectively uses one of the opposed end surfaces 12 and 14 as the upper surface 18, the other end surface is the lower surface. In this case, the top surface and the boss surface of the chip breaker on the other end surface can function as a seating surface that comes into contact with the bottom surface of the insert mounting seat provided in the cutting tool body.
- the cutting insert 10 described above is detachably mounted on an insert mounting seat provided on the cutting tool body.
- the cutting insert 10 is placed on the insert mounting seat with the lower surface 20 having a function as a seating surface and at least a part of the peripheral side surface 16 abutting against the bottom surface and the wall surface of the insert mounting seat, respectively.
- a screw hole is formed in the insert mounting seat. Then, the screw that engages or penetrates the mounting hole 28 of the cutting insert is screwed into the screw hole of the insert mounting seat, whereby the cutting insert 10 is detachably fixed to the cutting tool body.
- the attachment mechanism or means for attaching the cutting insert 10 to the cutting tool body is not limited to such a configuration. Other mechanical or chemical mechanisms or means may be employed as the attachment mechanism or means.
- the boss surface of one surface and the top surface of the chip breaker can contact the bottom surface of the insert mounting seat.
- the upper surface 18 is oriented in the cutting direction during cutting.
- one straight cutting edge 22b of the used cutting edges 22 'on the upper surface 18 and a part of the arc-shaped cutting edge 22a adjacent to the linear cutting edge 22b function as a transverse cutting edge facing the feed direction side.
- the remaining linear cutting edge 22b of the used cutting edge 22 'and the arcuate cutting edge 22a adjacent to the other linear cutting edge 22b do not function as the transverse cutting edge.
- This part functions as a front cutting edge facing the processing surface side of the work material.
- the used cutting edge is a portion of the cutting edge 22 that is cut into the work material, that is, a cutting edge that can be involved in cutting, in the cutting tool to which the cutting insert 10 is attached.
- the cutting insert 10 is used, for example, for turning the outer peripheral surface of the work material rotated around the rotation center line when fed in a direction parallel to the rotation center line of the work material.
- the horizontal cutting edge can be mainly responsible for cutting by contacting the work material over the entire cutting in a direction (cutting direction) perpendicular to the rotation center line.
- the front cutting edge can be in contact with the processed surface of the work material and be responsible for forming the processed surface.
- chips generated mainly by the horizontal cutting edge of the cutting insert 10 rise from the horizontal cutting edge and flow toward the wall surface 32a. At this time, the chips pass over the first rake face 24a while contacting the surface of the first rake face 24a.
- the cutting insert of this embodiment since the distance Wa is short, the first rake face 24a is narrow. Therefore, the size of the rake angle is largely influenced mainly by the rake angle of the second rake face 24b in the entire rake face involved in chip generation. For this reason, the cutting insert of this embodiment can reduce cutting resistance and can reduce the thickness of a chip.
- the rake angle of the second rake face is obviously larger than the rake angle of the first rake face, and thus the chip can be processed without contacting the chip with the second rake face 24b.
- such a rake face configuration further contributes to a reduction in cutting resistance. Therefore, the heat generation of the cutting insert and chips can be suppressed.
- the contact area between the chip and the cutting insert is small, it is possible to suppress the heat generated in the chip from propagating to the cutting insert. Therefore, an increase in the surface temperature of the cutting insert can be suppressed.
- Chips that have passed over the first rake face 24a flow onto the second rake face 24b.
- the rake angle ⁇ b of the second rake face 24b is larger than the rake angle ⁇ a of the first rake face 24a. That is, the rake face 24 has a convex shape. Therefore, chips flowing from the first rake face 24a to the second rake face 24b cannot positively or substantially contact the surface of the second rake face 24b. Therefore, the temperature rise of the chip is suppressed and the abrasion resistance between the chip and the rake face is greatly suppressed. Therefore, the tool life of the cutting insert can be improved.
- the chips when cutting a work material with high ductility, the chips are likely to be stretched and plastically deformed, and thus may contact the surface of the second rake face 24b.
- the rake angle ⁇ b of the second rake face is set to a large positive angle of 15 ° or more and 35 ° or less, the chips can be broken before the thickness thereof increases. Therefore, the temperature rise of the chip, the arc-shaped cutting edge 22a, the linear cutting edge 22b, the second rake face 24b, and the flank 26 due to the contact between the chip and the second rake face 24b is suppressed. Further, the abrasion resistance exerted on the second rake face 24b is effectively suppressed. Therefore, the life of the cutting insert is improved.
- the distance Wa from the cutting edge to the end portion of the first rake face is smaller than the radius of curvature of the arcuate cutting edge 22a provided in the corner portion 18c.
- the arcuate cutting edge 22a that affects the size of the feed amount f (mm / rev).
- the distance Wa is not excessive with respect to the radius of curvature. Therefore, the cutting insert 10 enables high feed cutting.
- the distance Wa from the cutting edge to the terminal portion of the first rake face is 0.05 mm or more and 0.30 mm or less.
- the distance Wb from the cutting edge to the end portion of the second rake face is set to 0.20 mm or more and 0.70 mm or less. This prevents the chips from coming into contact with the surface of the second rake face 46 during cutting of the work material that may generate easily-extensible chips. Therefore, an increase in temperature such as chips and an increase in scratch resistance exerted on the second rake face 24b can be suppressed.
- the rake angle ⁇ b of the second rake face is set to 15 ° or more and 35 ° or less.
- the rising portion 32b of the rising wall surface 32a is lower than the extended surface S1 extending the first rake face, and on or extending the extended face S2 extending the second rake face. It can be higher than the plane S2. Therefore, chips flowing substantially along the first rake face or chips passing substantially along the second rake face are surely in contact with the rising wall surface 32a. Chips are curled or broken into a curved shape, triggered by a sudden change in the flow direction due to this contact. Thereby, the stable chip processing is achieved.
- the inclination angle ⁇ of the rising wall surface 32a is larger than the rake angle ⁇ b of the second rake surface, a large deformation is given to the chips contacting the rising wall surface 32a. As a result, the chips can be curled or cut reliably.
- the inclination angle ⁇ is larger than the rake angle ⁇ b, it is possible to suppress scraping resistance by quickly separating the chips from the rising wall surface 32a.
- the chip that extends upward or spontaneously curls with respect to the first rake face 24a is raised. 32a can be reliably brought into contact with. Thereby, the chip processing can be improved.
- the distance Wc from the cutting edge to the rising portion of the rising wall is set to 0.70 mm or more and 1.50 mm or less as described above. This is for the purpose of making it possible for the spontaneously curled chips to reliably contact the rising wall surface. In addition, this is because when the extended chip comes into contact with the rising surface, the collision of the chip is too strong to suppress an increase in cutting resistance. Further, this is for smoothly curling or cutting the chips.
- a cutting insert 110 according to a second embodiment of the present invention will be described. However, below, only the main differences between the cutting insert 110 and the cutting insert 10 according to the first embodiment will be described. It should be noted that the constituent elements corresponding to the constituent elements already described are given the same reference numerals as the constituent elements already described, or the description thereof is omitted.
- the cutting insert 110 has a feature that the rising wall surface 132a includes two surfaces as compared with the cutting insert 10 described above.
- the configuration of the rising wall surface 132a is substantially similar to the configuration of the rake surfaces 24 and 124.
- FIG. 6 shows a cross-sectional view of the cutting insert 110 corresponding to the cross-sectional view of FIG.
- the rising wall surface 132a is substantially composed of two surfaces.
- a plane orthogonal to the cutting edge 122 that is, the first plane is defined.
- the first plane is substantially parallel to the axis A as described above.
- the rising wall surface 132a has two surfaces 132d and 132e so that the inclination angle of the rising wall surface 132a changes as the distance from the cutting edge 122 increases in any first plane.
- the first rising wall surface 132d and the second rising wall surface 132e are sequentially arranged in a direction away from the cutting edge 122.
- the first rising wall surface 132d is one region of the rising wall surface 132a and is a first rising wall surface region.
- the second rising wall surface 132e is another region of the rising wall surface 132a and is a second rising wall surface region.
- the first rising wall surface 132d and the second rising wall surface 132e are continuous.
- the first rising wall surface 132d extends at a cutting edge side end portion of the rising wall surface 132a
- the second rising wall surface 132e extends at a top surface 132c end portion of the rising wall surface.
- the inclination angle ⁇ a of the first rising wall surface 132d with respect to the second plane is larger than the inclination angle ⁇ b of the second rising wall surface 154 with respect to the second plane. Therefore, the rising wall surface 132a has a convex shape toward the upper surface 118 as a whole.
- the top surface 132c of the chip breaker raised portion 132 is formed to be higher than the cutting edge 122, like the top surface 32c. Further, the boundary portion or the intersecting portion 132f between the first rising wall surface 132d and the second rising wall surface 132e is located higher than the cutting edge 122 as shown in FIG. Is formed. Therefore, when defining a plane orthogonal to the axis A and passing through the cutting edge 122, this plane extends so as to cross the first rising wall surface 132d.
- the cutting insert 110 having such a configuration has the following actions and effects in addition to the actions and effects of the cutting insert 10.
- the rising wall surface 132a includes a first rising wall surface 132d and a second rising wall surface 132e, and the inclination angle ⁇ a of the first rising wall surface 132d is larger than the inclination angle ⁇ b of the second rising wall surface 132e. Therefore, the second rising wall surface 132e is greatly inclined with respect to the first rising wall surface 132d in a direction away from the arcuate cutting edge 122a and the linear cutting edge 122b, and the rising wall surface 132a has a convex shape as a whole. Therefore, when the chip contacting the first rising wall surface 132d is curled and flows upward and away from the arcuate cutting edge 122a and the linear cutting edge 122b, the chip contacts the second rising wall surface 132e.
- the contact area between the rising wall surface 132a and the chips is minimized, the chips are discharged smoothly, and good chip processing is possible. That is, the inclination angle of the second rising wall surface is different from the inclination angle of the first rising wall surface so as to promote chip discharge.
- the intersection 132f between the first rising wall surface 132d and the second rising wall surface 132e is higher than the arcuate cutting edge 122a and the linear cutting edge 122b. Therefore, chips passing along the first rake face 124a or the second rake face 124b can be reliably received by the first rising wall surface 132d. Further, the chips curled by contact with the first rising wall surface 132d can be smoothly discharged without contacting the second rising wall surface 132e.
- a cutting insert 210 according to a third embodiment of the present invention will be described. However, below, only the main differences between the cutting inserts 210 and 110 according to the first embodiment and the second embodiment described above in the cutting insert 210 will be described. It should be noted that the constituent elements corresponding to the constituent elements already described are given the same reference numerals as the constituent elements already described, or the description thereof is omitted.
- the cutting insert 210 has a feature that the rising wall surface 232a includes two regions, specifically, two surfaces 232d and 232e, as compared with the cutting insert 10 described above. Further, the cutting insert 210 is characterized in that the rake face 224 and the rising wall face 232a are respectively curved as compared with the cutting inserts 10 and 110. That is, each of the first rake face 224a, the second rake face 224b, the first rising wall surface 232d, and the second rising wall surface 232e has a curved shape.
- FIG. 7 shows a cross-sectional view of the cutting insert 210 corresponding to the cross-sectional view of the cutting insert 10 of FIG.
- the rake angle that is, the inclination angle of each of the first and second rake faces, and the inclination angle of each of the first and second rising wall surfaces are defined with respect to an imaginary line or a virtual plane.
- each of the first rake face 224a, the second rake face 224b, the first rising wall surface 232d, and the second rising wall surface 232e has a curved shape protruding toward the upper surface 18 side.
- each of these for example, the end on the cutting edge side or the end close to the cutting edge 222 and the other end (for example, the end on the top surface 232c side of the chip breaker raised portion 232 or the end far from the cutting edge 222).
- Angles between a straight line or a plane (two-dot chain line in FIG. 7) connected to the second plane or a horizontal plane are defined as respective rake angles or inclination angles. More specifically, the rake angle of the first rake face 224a is the cutting edge side end (starting end) of the first rake face 224a, for example, the arcuate cutting edge 222a, and the top face side end (terminal).
- the rake angle of the second rake face 224b is defined by the angle formed by the line L2 connecting the start end 224c and the end 224d of the second rake face or the surface S2 and the horizontal plane.

- the rake face has a positive rake angle over the entire cutting edge. Therefore, the thickness of the chip can be reduced.
- the cutting insert includes a first rake face and a second rake face that are sequentially arranged in the direction away from the cutting edge as described above, and the rake angle of these rake faces is gradually increased as the distance from the cutting edge increases. Become bigger. Therefore, the present invention further has an action and an effect of promoting chip flow and reducing chip thickness. Therefore, the temperature rise of the cutting edge, the first and second rake faces and the flank face is suppressed, and the tool life of the cutting insert can be improved.
- the present invention has an effect of reducing the chip thickness, in the generated chip, the temperature difference between the shear surface side (side facing the rake face) and the opposite side in the thickness direction becomes significant. Therefore, the curl deformation of the chips due to the temperature difference is promoted, and the chip processability is improved. Further, since the chip thickness is small, the progress of wear of the chip breaker due to the contact of the chips is suppressed. Therefore, the chip treatment by the rising wall surface of the chip breaker is stable for a long time.
