Description

本発明は、金属部品等の溝入れ加工に用いられる切削インサート及びそれを装着した切削工具に関する。   The present invention relates to a cutting insert used for grooving a metal part or the like and a cutting tool equipped with the cutting insert.

従来、金属部品等の溝入れ加工に用いられる切削インサートとして、特許文献１に示すような長手方向に延びた本体の両端に切刃部を形成したインサートが知られている。   Conventionally, as a cutting insert used for grooving of metal parts or the like, an insert having cutting edge portions formed at both ends of a main body extending in the longitudinal direction as shown in Patent Document 1 is known.

この特許文献１に記載の切削インサートは、切削インサートの長手方向の両端に切刃部が形成されており、該切刃部の上面にすくい面が、側面に前逃げ面と横逃げ面とが備えられている。そして、すくい面と前逃げ面との交差稜線に前切刃が、すくい面と横逃げ面との交差稜線に横切れ刃が形成された構成となっている。また、前逃げ面と横逃げ面を繋ぐコーナー部にはＲ状の曲面が備えられており、該曲面とすくい面との交差稜線にコーナーＲ切刃が形成されている。   In the cutting insert described in Patent Document 1, cutting edges are formed at both ends in the longitudinal direction of the cutting insert, a rake face is formed on the upper surface of the cutting edge, and a front flank and a side flank are formed on the side. It is provided. And the front cutting edge is formed in the intersection ridgeline of a rake face and a front flank, and the side cutting edge is formed in the intersection ridgeline of a rake face and a side flank. In addition, an R-shaped curved surface is provided at a corner portion connecting the front flank and the lateral flank, and a corner R cutting edge is formed at an intersecting ridge line between the curved surface and the rake face.

このような切削インサートは、前切刃が被削材の回転軸に平行となるように配置された後、前切刃を被削材の側面に当てて溝入れ加工が行われる。ここで、加工によって形成された溝の互いに対向する側壁の表面をより滑らかに仕上げるための手段として、特許文献１において、図６に示すようにコーナーＲ切刃から横切刃にかけて湾曲状のワイパー切刃を形成することが提案されている。
特表２００２−５１６１８５号公報 Such a cutting insert is grooved by placing the front cutting edge parallel to the rotation axis of the work material and then applying the front cutting edge to the side surface of the work material. Here, as a means for more smoothly finishing the surfaces of the side walls facing each other of the groove formed by machining, in Patent Document 1, as shown in FIG. 6, a curved wiper is applied from the corner R cutting edge to the horizontal cutting edge. It has been proposed to form a cutting edge.
Special table 2002-516185 gazette

しかしながら、上記のような湾曲状のワイパー切刃を形成した切削インサートで溝入れ加工した場合には、ワイパー切刃が溝側壁にくい込むために、切削抵抗が大きくなってビビリが発生したり、切れ味が低下することによって加工した溝側壁の表面がむしれてくるなどの問題があった。   However, when grooving is performed with a cutting insert having a curved wiper cutting edge as described above, the wiper cutting edge is difficult to get into the groove side wall, resulting in increased cutting resistance and chattering. There is a problem that the surface of the processed groove side wall is peeled off due to the decrease in the thickness.

本発明は、このような従来技術の課題を解決するためになされたものであり、金属部品等の溝入れ加工において、ビビリを発生させることなく、溝側壁の表面を滑らかに仕上げることのできる切削インサート及びそれを装着した切削工具を提供することを目的とする。   The present invention has been made in order to solve the problems of the prior art, and in grooving processing of metal parts and the like, cutting capable of smoothly finishing the surface of the groove side wall without generating chatter. An object is to provide an insert and a cutting tool on which the insert is mounted.

In this way, the wiper cutting edge between the corner cutting edge and the side cutting edge is formed without protruding to the side of the corner cutting edge, thereby increasing the cutting resistance and sharpness during grooving. Since the lowering is prevented, the surface of the groove sidewall can be finished smoothly without causing chatter.

以下、本発明の一実施形態にかかる溝入れ加工用切削インサートについて図面を参照し詳細に説明する。図１は、本実施形態にかかる溝入れ加工用切削インサート（以下、インサートと略す。）を示す斜視図であり、図２（ａ）は図１のインサートの上面図、（ｂ）は図１のインサートの正面図、（ｃ）は図１のインサートの側面図、図３は図１のインサートによる溝入れ加工の状態を示す概略図である。   Hereinafter, a cutting insert for grooving according to an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a grooving cutting insert (hereinafter abbreviated as an insert) according to the present embodiment, FIG. 2A is a top view of the insert of FIG. 1, and FIG. FIG. 3C is a side view of the insert of FIG. 1, and FIG. 3 is a schematic view showing a state of grooving by the insert of FIG. 1.

図１〜図２に示すように、本実施形態のインサート１は、ホルダ工具本体（図示せず）に装着するための上クランプ面と下クランプ面とからなるクランプ手段２を具備する中央本体部３と、中央本体部３の両端に突出した位置に形成された切削端部４とに大別される。切削端部４は、上面であるすくい面５と側面である前逃げ面６及び横逃げ面７から構成されており、すくい面５と前逃げ面６との交差稜線に前切刃８が、すくい面５と横逃げ面７との交差稜線に横切刃９が形成されている。また、前逃げ面６と横逃げ面７を繋ぐコーナー部には断面が円弧状の曲面１０が備えられており、該曲面１０とすくい面５との交差稜線に円弧状のコーナー切刃１１が形成されているとともに、コーナー切刃１１と横切刃９との間に直線状のワイパー切刃１４が形成されている。   As shown in FIGS. 1 to 2, the insert 1 of the present embodiment includes a central body portion having a clamp means 2 composed of an upper clamp surface and a lower clamp surface for mounting on a holder tool body (not shown). 3 and a cutting end portion 4 formed at positions protruding from both ends of the central main body portion 3. The cutting end 4 is composed of a rake face 5 that is an upper surface, a front flank face 6 and a side flank face 7 that are side faces, and a front cutting edge 8 is formed at the intersecting ridge line between the rake face 5 and the front flank face 6. A horizontal cutting edge 9 is formed at the intersecting ridge line between the rake face 5 and the side flank face 7. Further, a corner portion connecting the front flank 6 and the side flank 7 is provided with a curved surface 10 having an arc-shaped cross section, and an arcuate corner cutting edge 11 is formed at the intersecting ridge line between the curved surface 10 and the rake surface 5. A linear wiper cutting edge 14 is formed between the corner cutting edge 11 and the horizontal cutting edge 9.

そして、図３に示すように、インサート１が、前切刃８が被削材１２の回転軸１３に平行となるように配置され、前切刃８を被削材１２の側面に当てて溝入れ加工が行われる。   As shown in FIG. 3, the insert 1 is disposed so that the front cutting edge 8 is parallel to the rotation shaft 13 of the work material 12, and the front cutting edge 8 is applied to the side surface of the work material 12 to form a groove. Putting is performed.

この溝入れ加工においては、回転軸側にインサート１が送り込まれ、深さ方向に溝が切削されるとともに溝の両側面が切削されていくことになるが、この場合においては、コーナー切刃１１の切削した後の溝側壁面をワイパー切刃１４が追随することにより、溝側壁の表面を滑らかに仕上げることができる、すなわち、サラエ刃効果が得られることとなる。 In this grooving process, the insert 1 is fed to the rotating shaft side, the groove is cut in the depth direction and both side surfaces of the groove are cut. In this case, the corner cutting edge 11 is cut. When the wiper cutting blade 14 follows the groove side wall surface after cutting, the surface of the groove side wall can be finished smoothly, that is, the Sarae blade effect can be obtained.

ここで、ワイパー切刃１４は、コーナー切刃１１の側方に当該コーナー切刃１１より張り出すことのない状態で形成されている。したがって、コーナー切刃の側方に張り出した突出するような湾曲状のワイパー切刃を形成したインサートと異なり、ワイパー切刃が溝側壁にくい込むことがないので、切削抵抗が大きくなってビビリが発生するということがない。また、切れ味が低下することによる、溝側壁表面のむしれ現象も生じない。   Here, the wiper cutting edge 14 is formed in a state where it does not protrude from the corner cutting edge 11 to the side of the corner cutting edge 11. Therefore, unlike an insert that has a curved curved wiper cutting edge that protrudes to the side of the corner cutting edge, the wiper cutting edge does not slip into the groove side wall, resulting in increased cutting resistance and chatter. There is nothing to do. Moreover, the flaking phenomenon of the groove side wall surface due to the reduction in sharpness does not occur.

図３において、前切刃８とワイパー切刃１４とのなす角度をθとした場合に、θは８９°３０´＜θ＜９０°の範囲にあるのが望ましい。θが８９°３０´より小さいとサラエ刃効果が低下するため、十分に滑らかな溝側壁面を得ることができず、また９０°より大きいと、溝側壁にワイパー切刃１４がくい込む構成となるため、切削抵抗が増大するとともに、ビビリも発生しやすくなる。 In FIG. 3, when θ is an angle formed by the front cutting edge 8 and the wiper cutting edge 14, θ is preferably in the range of 89 ° 30 ′ <θ <90 °. If θ is less than 89 ° 30 ′, the Sarae blade effect is reduced, so that a sufficiently smooth groove side wall surface cannot be obtained. If it is larger than 90 °, the wiper cutting edge 14 is inserted into the groove side wall. Therefore, cutting resistance increases and chattering is likely to occur.

また、ワイパー切刃１４の幅Ｗは、コーナー切刃１１の曲率半径Ｒに対して、０．５Ｒ＜Ｗ＜２Ｒの範囲にあるのが好ましい。Ｗが２Ｒより大きいと、ワイパー切刃１４と溝側壁との接触領域が広くなるために切削抵抗が大きくなり、結果としてビビリが発生しやすくなる。また、通常の溝入れ加工においては、コーナー切刃１１の曲率半径Ｒの約１／2の大きさの送り量で加工するのが一般的であるため、Wが０．５Ｒより小さいとWが送りより短くなってしまい、ワイパー切刃１４の作用する領域が一部に限られてしまう恐れがある。   The width W of the wiper cutting edge 14 is preferably in a range of 0.5R <W <2R with respect to the radius of curvature R of the corner cutting edge 11. When W is larger than 2R, the contact area between the wiper cutting edge 14 and the groove side wall becomes wide, so that the cutting resistance increases, and as a result, chatter is likely to occur. Further, in normal grooving, it is common to process with a feed amount that is about 1/2 of the radius of curvature R of the corner cutting edge 11. Therefore, if W is less than 0.5R, W is less than 0.5R. There is a possibility that the region where the wiper cutting blade 14 acts is limited to a part because the length becomes shorter than the feed.

一方、このようなワイパー切刃１４とこれに隣接する逃げ面は、研磨加工により精度良く形成することが、サラエ刃効果がより確実に得られる点で望ましい。上述のθやＷが精度良く形成されないと、サラエ刃効果が得られないとともに切れ味も低下する原因となるからである。   On the other hand, it is desirable that the wiper cutting blade 14 and the flank adjacent to the wiper cutting blade 14 be formed with high precision by polishing so that the Sarah blade effect can be obtained more reliably. This is because if the above-mentioned θ and W are not formed with high accuracy, the Sarah blade effect cannot be obtained and the sharpness is reduced.

また、上記研磨加工の研磨方向（研摩痕１５）が、ワイパー切刃１４の稜線方向に対して４５°〜９０°で形成されていることが好ましい。研磨方向が０°（稜線に平行な方向）〜４５°の範囲にあると、インサートの製造工程において、加工条件等のミスマッチによってワイパー切刃１４にチッピングが生じた場合、切刃上でチッピングが伝播してワイパー切刃１４の広範囲にわたってチッピングを生じやすく、切削時におけるワイパー作用が大きく損なわれる結果となる。すなわち、図４に示すように、力Ｐで研摩される場合に、研摩方向がワイパー切刃１４の稜線方向に対して４５°〜９０°である（ａ）の場合のワイパー切刃方向の分力Ｐ１と、研摩方向がワイパー切刃１４の稜線方向に対して４５°以内である（ｂ）の場合のワイパー切刃方向の分力Ｐ２とを比較すると、明らかにＰ１＜Ｐ２となり、研摩方向がワイパー切刃１４の稜線方向に対して４５°以内である方が、研摩時に切刃上に発生したチッピングを切刃上にひきずりやすい。これに対し、研磨方向が４５°〜９０°の範囲にあれば、仮に加工でチッピングが生じたとしても、発生する箇所は局部的な範囲に限られ、切削時におけるワイパー作用が大きく損なわれることがない。   Moreover, it is preferable that the polishing direction (polishing mark 15) of the polishing process is formed at 45 ° to 90 ° with respect to the ridge line direction of the wiper cutting edge 14. When the polishing direction is in the range of 0 ° (direction parallel to the ridgeline) to 45 °, when chipping occurs in the wiper cutting blade 14 due to a mismatch in processing conditions or the like in the insert manufacturing process, chipping occurs on the cutting blade. Propagation is likely to cause chipping over a wide range of the wiper cutting edge 14, resulting in a significant loss of the wiper action during cutting. That is, as shown in FIG. 4, when polishing is performed with a force P, the direction of the wiper cutting edge when the polishing direction is 45 ° to 90 ° with respect to the ridge line direction of the wiper cutting edge 14. When the force P1 and the component force P2 in the wiper cutting edge direction when the polishing direction is within 45 ° with respect to the ridge line direction of the wiper cutting edge 14 are compared, it is clear that P1 <P2, and the polishing direction When the angle is within 45 ° with respect to the ridge line direction of the wiper cutting edge 14, chipping generated on the cutting edge during polishing is likely to be dragged onto the cutting edge. On the other hand, if the polishing direction is in the range of 45 ° to 90 °, even if chipping occurs during processing, the generated location is limited to a local range, and the wiper action during cutting is greatly impaired. There is no.

なお、図５には、本発明の他の実施形態にかかる切削インサートの斜視図を示している。図５の切削インサートは、略三角形板状の中央本体部を有するとともに三つの隅部に切削端部を設けたもので、略三角形板状の厚み方向と平行に前切刃を配置した構成である。このような構成の切削インサートであっても、切削端部の構成が上述した第一の実施形態と同様であるので、切削性能については同様の性能が得られる。     In addition, in FIG. 5, the perspective view of the cutting insert concerning other embodiment of this invention is shown. The cutting insert of FIG. 5 has a substantially triangular plate-shaped central main body portion and three cutting edge portions provided with cutting end portions, and has a configuration in which a front cutting edge is arranged in parallel with the substantially triangular plate-shaped thickness direction. is there. Even in the cutting insert having such a configuration, the configuration of the cutting end is the same as that of the first embodiment described above, and therefore the same performance can be obtained with respect to the cutting performance.
