Definitions
- the present invention relates to a cutting insert and a cutting edge exchangeable cutting tool to which the cutting insert can be attached.
- Burr generated by face milling is generally removed by a deburring process provided after the face milling is completed.
- a technique for suppressing burr or chipping by face milling has been conventionally known. Such conventional techniques include the following.
- an object of the invention of Patent Document 1 is to use a front milling machine in which a roughing insert for performing main cutting and a burr suppressing insert provided with a burr suppressing dedicated blade are used in combination. Since this is to suppress the occurrence of the above, there are the following problems.
- the second problem is that there is a difference in tool life between the roughing insert and the burr suppression insert, and when either one reaches the tool life, both inserts may have to be replaced at the same time. There are many. Therefore, each cutting insert cannot be used effectively, and the tool cost increases.
- the present invention has been made to solve the above problems. That is, it aims at providing the cutting insert which has both the cutting edge for rough machining, and the cutting edge for burr
- the cutting edge replaceable cutting tool of the present invention is a cutting edge replaceable cutting tool having the cutting insert of the present invention and a tool main body provided with an insert mounting seat for detachably mounting the insert at a predetermined position.
- the cutting insert attached to the tool body is arranged such that each of the first main cutting edge and the second main cutting edge protrudes from an outer peripheral surface and a tip surface of the tool body,
- the downward inclined portion of the second main cutting edge has a negative cutting angle
- the upward inclined portion of the second main cutting edge has a positive cutting angle.
- the first main cutting edge and the corner portion are responsible for rough cutting of the work material.
- a part of the upward inclined portion of the second main cutting edge acts as a burr suppressing blade having a slight cutting angle.
- ⁇ / RTI> Near the intersection of the descending slope part and the ascending slope part of the second main cutting edge forms an escape part that does not come into contact with the work material. Since the burr suppression blade constituted by a part of the upward inclined portion and the first main cutting edge and the corner portion are separated from each other with the relief portion interposed therebetween, chips generated from the burr suppression blade And the chip
- the radial rake angle of the ascending slope that becomes the burr suppression blade is tilted to the negative side. Therefore, the direction of the reaction force due to the cutting force generated in the upward inclined portion is directed to the outside of the cutting tool. That is, when the cutting insert is pulled out by rotation, the burr is directed in the direction of separating from the work material. Further, as compared with the case where the inclination to the negative side of the radial rake angle is small, the ascending slope part gradually separates from the work material over time. In other words, the cutting blade passes through the detached portion from the work material while being largely inclined. In order to cut the work material in a state where the cutting edge is inclined, the cutting resistance is further reduced, and the burr is reliably cut off. This effectively prevents the generation of burrs.

Therefore, when the cutting insert comes off the work material, a force acts in the direction of separating the burr from the work material, so that the burr can be effectively suppressed.
- the present invention is not limited to the embodiment described above.

切れ刃はすくい面11と逃げ面12との交差稜線部に形成される。すくい面11と逃げ面12とは鋭角に交差しており、逃げ面12は正の逃げ角を付されている。つまり、この切削用インサート1は、八角形の上面の4箇所に形成されたコーナ部20のみを使用する、
また、第2の主切れ刃22に隣接するすくい面11bは、下り傾斜部22aおよび上り傾斜部22bに対応した下り傾斜面および上り傾斜面を有するとともに、第2の主切れ刃22から遠ざかるにつれ、切削用インサート1の厚みを減じる方向に傾斜しており、正のすくい角を有する。
逃がし部24を構成しない上り傾斜部22bの残りの部分は、コーナ部20の最先端より工具先端側に突き出ており、切削に関与するバリ抑制刃25を構成している。バリ抑制刃25の内周端およびこの内周端から内周側へ延びるさらい刃23は、最も先端側に位置しており、コーナ部20の最先端に対して0.1mm以上0.3mm以下の突出量を有する。さらい刃23は直線状をなし工具本体101の回転軸線AXに直交する平面と略平行な方向に延びる。さらに、バリ抑制刃25の切込み角κ2は、第1の主切れ刃21の切込み角κ1にくらべ非常に小さく、5°以上15°以下の範囲にある。
