Definitions
- the present invention relates to an insert having a polygonal shape and a cutting edge provided on at least one side of the polygon.
- the rake face is formed in the same plane as the flat face of the insert or in a groove shape. Therefore, for example, in order to obtain a rake angle corresponding to the hardness or the like of the material to be cut, it is necessary to appropriately set the fixed posture itself of the insert with respect to the rotary cutting tool. Also, since the rake face is formed by the flat face of the insert, it is necessary to increase the thickness of the insert as a whole in order to increase the strength of the cutting edge. In this case, the material cost increases. Furthermore, since the conventional insert is formed with one cutting edge portion for one insert, the frequency of replacement of the insert is high during the machining operation.
- the present invention has been made in view of the above circumstances, and it is possible to set a rake angle according to a material to be cut while maintaining a fixed posture of the insert with respect to the rotary cutting tool, and to improve the use efficiency of the insert.
- An object is to provide an insert that can be enhanced.
- the first characteristic configuration of the insert according to the present invention has a polygonal shape, and has a cutting edge portion on at least one side of the polygon.
- the cutting edge portion includes a rake face having a convex portion provided on one surface in the thickness direction, and a flank having a concave portion provided in a surface intersecting the one surface in the thickness direction. It is in the point provided with the formed concave cutting edge.
- the rake face in a shape having a convex portion, a predetermined rake angle can be obtained without tilting and fixing the insert with respect to the rotary cutting tool.
- the convex part in which a rake surface is formed is formed in the state which added the thickness of the said convex part with respect to the thickness of insert, the intensity
- a cutting edge part can be formed in each edge
- the second characteristic configuration of the present invention is that the rake face is formed so that cutting edges of various dimensions are stacked in a contour line shape.
- the concave cutting blade which has a different curvature with respect to one convex part can be formed.
- various cutting blades having the same rake angle can be obtained by cutting the convex portion using a grinding tool or the like having a different curvature. Therefore, the cutting edge part with the same curvature can be formed on each side of the polygonal shape, and the cutting edge part with a different curvature can be formed respectively.
- an insert having excellent cost performance can be obtained.
- the flank surface is a concave surface extending from the cutting edge portion toward the other surface in the thickness direction, and the concave surface perpendicular to the thickness direction is provided.
- the cross-sectional shape is equally formed at any position from the cutting edge portion toward the other side surface, or the cross-sectional shape of the concave surface perpendicular to the thickness direction is from the cutting edge portion to the other side. It is in the point formed so that a concave curvature may become small, so that the surface of this is approached.
- the flank can be formed simultaneously with the formation of the cutting edge by using, for example, a cylindrical rotary grinding tool having the curvature of the cutting edge to be formed to form the flank. . Therefore, the manufacturing efficiency of the insert is improved. If the flank is such that the concave curvature decreases as it approaches the other surface from the cutting edge, a larger clearance between the workpiece and the flank can be secured. Therefore, interference between the insert and the workpiece can be reliably prevented, and high-quality rounded portion machining can be performed. Thus, even when the curvature of the flank changes, the cutting edge and the flank can be formed simultaneously by using, for example, a conical grinding tool.
- FIG. 3 is a perspective view showing a blank before forming a cutting edge part. These are the top views of a blank.
- FIG. 3 is a side view of a blank.

As shown in FIG. 4, the cutting blade 4 having a predetermined curvature must be formed within a limited range of the convex portion 5, and when the expected edges of the cutting blades 4 are compared as shown in FIG. 4. The width of the edges in the direction along the reference line X is narrower than the width of the edges along the direction perpendicular to the reference line X. This is because when the cutting blades 4 of various sizes are ground, the amount of grinding with respect to the base portion 1 is reduced to reduce the processing amount itself, or the volume of the base portion 1 is reduced to maintain the strength. It is necessary. Thus, the convex surface portion 5 has a shape obtained by superimposing the expected edges on which the cutting blade portions of the above shapes are formed.

Abstract
Description
また、すくい面がインサートの扁平な面で形成されているので、切刃部の強度を高めるためには、インサートの厚さを全体に厚くする必要があり、特にインサートを焼結金属などで形成する場合に材料コストが上昇するという欠点がある。
さらに、従来のインサートは、一つのインサートに対して一つの切刃部が形成されているため、加工作業に際してインサートの交換頻度が高いものとなっていた。
本発明は上記実情に鑑みてなされたものであって、インサートの回転切削工具に対する固定姿勢を一定にしながら、被切削材料に応じたすくい角を設定することができ、しかも、インサートの使用効率を高め得るインサートを提供することを目的とする。
前記切刃部が、厚さ方向の一方側の面に設けた凸部を有するすくい面と、当該厚さ方向の一方側の面に対して交差する面に設けた凹部を有する逃げ面とで形成した凹状の切刃を備えた点にある。
また、すくい面が形成される凸部は、インサートの厚さに対して当該凸部の厚みを加えた状態に形成されるから、ここに形成される切刃部の強度が高いものとなる。
さらに、多角形状を有するインサートの各辺に切刃部が形成できるから、一つのインサートを切刃部の数だけ繰り返し使用することができる。この結果、切削作業の加工効率が向上し、加工コストを低減化することができる。
〔第1実施形態〕
図1,図2に、本発明に係るインサートの一例を示す。インサートAは、図7に示すように被切削材料Dの角部をアール形状(曲面形状)に面取り加工するために回転切削工具Cに固定される。インサートAは、例えば、超硬合金等を用いて形成する。
インサートAは、平面視で略正四角形に形成された基体部1を備えている。基体部1の中央には、基体部1を回転切削工具Cに固定するための一つの固定用孔部2を設けてある。基体部1の各一辺には、四つの切刃部3を備えている。
図3~図6は、上記切刃部3を形成する前のブランクBを示す。四辺の夫々には、すくい面形成用の凸面部5をブランクBの厚み方向に突設してある。
こうすることで、切刃4を加工する場合に、切刃4と固定用孔部2との間隔が広がり、切刃4の加工可能なサイズ幅を拡大することができる。また、切刃4をオフセットして形成してあると、図7(a)に示すごとく、回転切削工具CにインサートAを装着したとき、
回転切削工具Cの回転中心から切刃4までの回転半径が短くなる。この結果、加工時に切刃4が被切削材料Dから受ける加工反力が小さくなり、回転切削工具Cが備えるべき駆動トルクを低減化することができる。
この凹状面10は、例えば所定の円錐面の一部で形成する。図5に示すように、裏面7における凹状面10の間隔Tは、表面6における凸面部5の間隔Uと比較してそれ以上に形成してある。前記凸面部5の裏側には切刃4のサイズに合わせた逃げ面11を形成するが、上記凹状面10は、逃げ面11の加工に先立って基体部1の側面8を肉抜きしたものである。
前記間隔Tを間隔Uのサイズ以上に形成したのは、例えば後に切刃4を加工する際に用いる研削工具の都合などによる。切刃4を加工するには、例えば切刃4の曲率を有する円筒状の砥石等を用い、これを所定の逃げ角に傾けた状態で側面8を削っていく。間隔Uの幅一杯の切刃4を加工する場合には、側面8を研削する量が最大となる。この場合、側面8の裏面側も当然に削られるので、当該部分を予め凹状に形成しておき、加工効率の向上を図っている。
一方、図2(b),図3に示すごとく、円筒状逃げ面11aに隣接する状態に平面状逃げ面11bを設けてある。この結果、上記円弧状切刃4aの両外側には直線状切刃4bが形成される。尚、この直線状切刃4bも、曲面上の凸面部5の表面に形成されるから厳密には直線状ではない。ただし、以下においては便宜上、直線状切刃4bと称する。
これら平面状逃げ面11bおよび直線状切刃4bは、被切削材料Dの角部を面取り加工した際に、加工した曲面と未加工の平面とを滑らかに連続させるためのものである。このような平面状逃げ面11bおよび直線状切刃4bは、例えば、円筒状の回転砥石を側面8に一旦押し付け、所定の深さまで円弧状切刃4a及び円筒状逃げ面11aを形成した後、この位置を基準にして左右の所定方向に回転砥石を平行移動させることで形成する。
ヘッド13は図中の矢印aの方向に回転し、インサートAを固定する固定座9を備えている。この固定座9は、基体部1の裏面7を密着させる固定座面9aと、基体部1の隣り合う二辺の側面8を密着させて基体部1を回り止めするよう互いに交差した回止用座面9bとからなる。図7(a)では、回止用座面9bを、ヘッド13の回転軸芯Zに対して45度の角度で交差する姿勢に形成してある。また、固定座面9aはヘッド13の回転軸芯Zと平行に設けてある。
図8乃至図11に、インサートAの別実施形態を示す。
ここでは、基体部1の各辺毎に、すくい面形成用の凸面部5を複数設ける。例えば、凸面部5として外側凸面部51と内側凸面部52とを設け、その間に段部16を設ける。図8及び図9は、外側凸面部51に切刃4を形成した例を示しており、図10及び図11は、内側凸面部52に切刃4を形成した例を示している。尚、凸面部は二つ以上設けるものであってもよい。
図12~図14は、切刃4を形成する前のインサートAを示す。
ここでは外側凸面部51と内側凸面部52との間の段部16が、基体部1の表面6そのもので形成してある。よって、表面6に対して外側凸面部51の高さと内側凸面部52の高さとの差が小さい。
当該インサートAは、例えば鋳造や焼結により形成する。外側凸面部51と内側凸面部52との間の凹部は、鋳造時等に一度に形成するものであっても良いし、一旦インサートAのブランク材を形成した後、凹部の部分だけを研削等によって形成してもよい。
上記各実施形態においては、切刃形状として単一のアール(円の一部)形状を有するものを示した。しかし、当該形状に限られるものではなく、例えば、複数のアール形状を複合して形成した凹状の切刃等であっても良い。
