Definitions
- the present invention relates to a cutting auxiliary lubricant and a cutting method.
- CFRP Fiber reinforced plastics
- CFRP Fiber Reinforced Plastics
- CFRP Carbon Fiber Reinforced Plastics
- AFRP reinforced plastic
- SUS stainless steel
- CFRP refers to a plastic obtained by laminating one or two or more prepregs obtained by impregnating a carbon fiber with a matrix resin, followed by heat molding or heat pressure molding.
- the member formed of CFRP is fixed to the structure using fastening elements such as bolts and rivets. For this reason, when CFRP is fixed to a structure such as an aircraft part, it is necessary to perform a cutting process, in particular, a cutting process in which a large number of holes for passing fastening elements are formed in the CFRP.
- the aircraft body structural material is mainly made of metal, and most of it is made of aluminum alloy.
- titanium alloy or stainless steel which is a heat-resistant alloy, is used in places where the temperature of the airframe structure can be higher, for example, in the vicinity of jet exhaust places and afterburners.
- a harder titanium alloy or stainless steel will be used as the structural material as the main body of the airframe structure.
- the cutting process for the fiber reinforced composite material is usually performed using a drill.
- the drill life is extremely short, and as the number of processed holes increases, wear of the drill blade occurs, and the quality of the processed hole decreases.
- the inner diameter of the processed hole tends to be small, and the carbon fiber is not cut off at the exit portion through which the drill penetrates (a part of the fiber forming the fiber-reinforced composite material is not cut and the cut hole is This is a phenomenon that remains in the surroundings.), And peeling between the prepregs forming the fiber-reinforced composite material (hereinafter referred to as “delamination”) is also likely to occur.
- CFRP cutting As the cutting tool wears and the cutting resistance increases, the quality problem of the drilled hole is more likely to occur.
- the carbon fibers are present at a high density, so the frequency at which the drill rubs the carbon fibers increases, and the wear of the cutting tool proceeds faster.
- the tool change is accelerated in order to maintain the hole quality, and the ratio of the tool cost to the processing cost is high at present.
- metal cutting is performed using a drill, but even if a metal-dedicated drill is used, the drill life is short, and when a general drill is used, the drill life is extremely short. Further, as the number of processed holes increases, wear of the drill blade occurs, and the quality of the processed holes decreases. Specifically, the inner diameter of the processed hole is likely to be small, and burrs are likely to occur at the exit portion through which the drill passes. In addition, due to wear of the drill, a gap is generated between the metal material to be fastened with the bolt and a structural material of another material such as CFRP, and floating is generated between these structural materials, or machining waste enters the generated gap. There is. Such a phenomenon is recognized as a serious defect.
- the drill part the entrance or exit part through which the drill passes (hereinafter referred to as the drill part) , Collectively referred to as “periphery of the cutting part”), there arises a problem that burrs, chips or uncut fibers are likely to occur. This is because the diameter of the drill bit is large, the volume of the material to be processed that is removed by the cutting process is increased, and the load on the drill bit is increased.
- the cutting tool is more easily worn than the work of the thin work material, and the entrance portion or the exit portion through which the cutting tool penetrates (hereinafter referred to as the following) (Also collectively referred to as the “periphery of the cutting portion”), there is a problem that burrs, chips, or uncut fibers are likely to occur. This is because the material to be processed is thick, and thus the volume of the material to be processed that is removed by the cutting process increases, and the load on the cutting tool increases.
- the present invention has been made in view of the above-described problems, and is intended to cut a material to be processed (particularly cutting a difficult-to-cut material having a curved surface, cutting a difficult-to-cut material that forms a hole having a large diameter, In cutting of difficult-to-cut materials), it is possible to reduce the load on the cutting tool, and to reduce chipping, burrs, or fiber breakage around the cutting portion, and the cutting auxiliary lubricant, and the cutting An object of the present invention is to provide a cutting method using a processing auxiliary lubricant.

本実施形態の切削加工補助潤滑材は、重量平均分子量が5×104以上、1×106以下である高分子量化合物(A)と、重量平均分子量が1×103以上、5×104未満である中分子量化合物(B)と、平均粒子径が100μm以上であるカーボン(C)と、を含有する。
高分子量化合物(A)は潤滑剤として機能することができ、切削加工補助潤滑材の潤滑性を向上させ、切削部周辺にできる欠け、バリ、又は繊維の切れ残りを抑制するという効果を発揮し得る。さらに、高分子量化合物(A)は成形剤として機能することができ、切削加工補助潤滑材の成形性を向上させる。これにより、種々の形状の切削加工補助潤滑材を成形可能であり、また単層形成(支持基材を用いることなく、それ自体で層(シート)を形成することが出来ること)も可能となる。また、高分子化合物(A)は、切削加工補助潤滑材に、追従性、靭性を付与することにより、曲面の切削加工性を向上させる効果も有する。
中分子量化合物(B)は潤滑剤として機能することができ、切削加工補助潤滑材の潤滑性を向上させ、切削部周辺にできる欠け、バリ、又は繊維の切れ残りを低減できるという効果を発揮し得る。
カーボン(C)は固体潤滑剤として機能することができ、切削加工補助潤滑材の潤滑性を向上させ、切削工具の寿命を延ばす効果を発揮し得る。さらに、カーボン(C)は切削加工時の温度において、体積を有する固体状で存在するため、切削加工時の潤滑性を維持できる。カーボン(C)としては、平均粒子径が100μm以上であれば、特に限定されないが、例えば、天然黒鉛、人造黒鉛、活性炭、アセチレンブラック、カーボンブラック、コロイド黒鉛、熱分解黒鉛、膨張化黒鉛、鱗片状黒鉛が挙げられる。この中でも、鱗片状の形状を有するカーボン(C)が好ましい。カーボン(C)が鱗片状の形状を有することにより、摩耗低減性能がより向上する傾向にある。カーボン(C)は1種を単独で用いても、2種以上を混合して用いてもよい。
本実施形態の切削加工補助潤滑材は、必要に応じて、その他の成分を含んでもよい。その他の成分としては、潤滑性向上成分、シート形成性向上成分、可塑剤、柔軟剤、表面調整剤、レベリング剤、帯電防止剤、乳化剤、消泡剤、ワックス添加剤、カップリング剤、レオロジーコントロール剤、防腐剤、防黴剤、酸化防止剤、光安定剤、核剤、有機フィラー、無機フィラー、固体潤滑剤、熱安定化剤、着色剤などが挙げられる。
本実施形態の切削加工補助潤滑材は、切削加工補助潤滑材の被加工材料と接する面に、粘着層を有していてもよい。粘着層を有することにより、切削加工補助潤滑材と被加工材料の密着性がより向上する傾向にある。
粘着層を除く切削加工補助潤滑材の厚さは、被加工材料の切削加工の際の切削方法、切断方法、加工する部分の面積や体積、切削工具の種類、被加工材料の構成、厚さなどによって適宜選択されるので、特に限定されない。このなかでも、切削加工補助潤滑材の厚さは、好ましくは0.1mm以上であり、より好ましくは0.2mm以上であり、さらに好ましくは0.5mm以上である。また、切削加工補助潤滑材の厚さは、好ましくは20mm以下であり、より好ましくは10mm以下であり、さらに好ましくは5mm以下である。切削加工補助潤滑材の厚さが0.1mm以上であることにより、十分な切削応力低減が得られ、切削工具への負荷が小さくなり、ドリル折損等をより抑制できる傾向にある。また、切削加工補助潤滑材の厚さが20mm以下であることにより、切削工具への切削加工補助潤滑材の巻き付きが減少し、切削加工補助潤滑材における亀裂発生をより抑制できる傾向にある。
本実施形態の切削加工補助潤滑材の製造方法としては、特に制限されるものではなく、高分子材料などの樹脂と充填材(例えば、無機充填材)とを含む樹脂組成物を、シートや、丸棒の形状や角棒の形状などのブロック状態に成形する従来公知の方法を広く利用することができる。例えば、高分子量化合物(A)、中分子量化合物(B)、及びカーボン(C)を、溶媒の存在下又は溶媒の非存在下で混合し、支持体に塗布、冷却、固化させてシートを形成し、その後、支持体を除去、剥離して切削加工補助潤滑材を得る方法;高分子量化合物(A)、中分子量化合物(B)、及びカーボン(C)を、溶媒の存在下又は溶媒の非存在下で混合し、シートの形状に押出成形して、必要に応じて延伸することにより切削加工補助潤滑材を得る方法などが挙げられる。
本実施形態の切削加工方法は、切削加工補助潤滑材を、切削工具及び/又は被加工材料の被加工部分に接触させながら、前記切削工具により前記被加工材料を切削し、切削部を形成する切削加工工程を有し、前記被加工材料が、繊維強化複合材、難削金属材、又は繊維強化複合材と難削金属材との複合材料を含む。
(態様1) 切削加工工程が、切削工具の出口と入口を有する切削部(例えば、加工孔)を形成する工程であるとき、切削加工工程前に、被加工材料の切削工具の出口となるべき部分及び/又は入口となるべき部分に、予め切削加工補助潤滑材を密着させる密着工程を有する態様(図1及び2)
(態様1-1) 態様1の密着工程において、前記被加工材料の前記切削工具の入口となるべき部分に、予め前記切削加工補助潤滑材を密着させる態様
(態様1-2) 態様1の密着工程において、前記被加工材料の前記切削工具の出口となるべき部分に、予め前記切削加工補助潤滑材を密着させる態様
(態様2) 切削加工工程前において、切削工具に切削加工補助潤滑材を予め接触させる接触工程を有する態様
(態様3) 切削加工工程において、切削工具に他の切削加工補助潤滑材を接触させた状態で、切削加工補助潤滑材が密着した被加工材料を切削し、切削部を形成する態様(図3)
態様1の切削加工方法は、切削加工工程が、切削工具の出口と入口を有する切削部(例えば、加工孔)を形成する工程であるとき、切削加工工程前に、被加工材料の切削工具の出口となるべき部分及び/又は入口となるべき部分に、予め切削加工補助潤滑材を密着させる密着工程を有する。ここで、「出口となるべき部分」とは、当該部分が面である場合には、出口となるべき面とも言い換えることができる。これに対応して、「入口となるべき部分」とは、入口となるべき面とも言い換えることができる。
態様1-1においては、被加工材料1の切削工具3の入口となるべき部分に、予め切削加工補助潤滑材2を密着させ、切削工具3を用いて被加工材料1を加工する(図1)。この場合、切削加工補助潤滑材2は、被加工材料1よりも前に切削工具3と接する。
態様1-1の切削加工方法は、被加工材料の切削工具の入口となるべき部分に、予め切削加工補助潤滑材を密着させる密着工程を有する。当該密着工程は、被加工材料の切削工具の入口となるべき部分に、予め切削加工補助潤滑材を密着させる工程である。被加工材料上の切削加工補助潤滑材の密着箇所は、予め、切削工具の入口となるべき部分とする。これにより、加工する直前に、工具の先端に切削加工補助潤滑材の潤滑成分が移行する。そのため、切削加工補助潤滑材の潤滑効果が十分に発揮される。これにより、切削工具への負荷をより低減させることができ、切削工具の入口周辺にできる欠け、バリ、又は繊維の切れ残りを抑制することができる傾向にある。
態様1-2においては、被加工材料1の切削工具3の出口となるべき部分に、予め切削加工補助潤滑材2を密着させ、切削工具3を用いて被加工材料1を加工する(図2)。この場合、切削加工補助潤滑材2は、被加工材料1を貫通してきた切削工具3と接する。
態様1-2の切削加工方法は、被加工材料の切削工具の出口となるべき部分に、予め切削加工補助潤滑材を密着させる密着工程を有する。当該密着工程は、被加工材料の切削工具の出口となるべき部分に、予め切削加工補助潤滑材を密着させる工程である。被加工材料上の切削加工補助潤滑材の密着箇所は、予め、切削工具の出口となるべき部分とする。これにより、上述したように切削工具への負荷を低減させることができ、切削工具の出口周辺にできる欠け、バリ、又は繊維の切れ残りを低減させることができる。
態様2の切削加工方法は、切削加工工程前において、切削工具に切削加工補助潤滑材を予め接触させる接触工程を有する。切削工具に切削加工補助潤滑材を予め接触させることにより、切削工具の入口となるべき部分に切削加工補助潤滑材を密着させる場合と同等の効果を得ることができる。接触方法は特に限定されないが、例えば、予め、切削加工補助潤滑材に切削工具に塗布することで、切削加工補助潤滑材を切削工具に付着させることができる。また、切削加工をする前に、切削工具で切削加工補助潤滑材を切断、孔あけすることで、切削加工補助潤滑材を切削工具に付着させることができる。
態様3の切削加工方法は、切削加工工程において切削工具に他の切削加工補助潤滑材を接触させた状態で、切削加工補助潤滑材が密着した被加工材料を切削し、切削部を形成する。切削加工工程において、切削工具に他の切削加工補助潤滑材を接触させ、付着させることにより、切削工具の入口となるべき部分に切削加工補助潤滑材を密着させる場合と同等の効果を得ることができる。本実施形態の切削加工方法においては、切削工具の入口となるべき部分及び出口となるべき部分の両方に切削加工補助潤滑材が密着した被加工材料を切削する場合においても、切削加工工程前に切削工具へ切削加工補助潤滑材を予め接触させる接触工程を有してもよく、切削加工工程において切削工具に他の切削加工補助潤滑材を付着させて切削部を形成してもよい。
被加工材料が厚い場合であっても、本実施形態の切削加工方法であれば、上記の効果が得られる。そのため、被加工材料の厚みを厚くすることが可能となる。被加工材料の厚さは、好ましくは3mm以上であり、より好ましくは5mm以上であり、さらに好ましくは10mm以上であり、よりさらに好ましくは15mmであり、さらにより好ましくは17.5mm以上である。また、被加工材料の厚さの上限は、特に限定されないが、40mm以下が好ましい。
さらに、切削加工補助潤滑材は、被加工材料の被加工部分が平面である場合のみならず、被加工部分が曲面である場合にも平面である場合と同様に好適に用いることができる。具体的には、切削加工補助潤滑材は、たわみ性、被加工部分への追従性に優れ、曲面を有する被加工材料に密着した状態で切削加工が可能となる。また、特に限定されないが、切削加工補助潤滑材は、切削加工補助潤滑材自体のたわみ性、被加工部分への追従性を妨げない構成を有することが好ましく、具体的には、厚い金属箔などを備えない態様が好ましい。これにより、曲面を有する被加工材料の切削加工性がより向上する。また、切削加工補助潤滑材が金属箔を備えない場合には、金属箔由来の切削金属屑が被加工材料の切削部へ溶着し、被加工材料の切削部を汚染することが抑制できる。その結果、従来技術よりも品質に優れる切削加工が可能となる。
切削加工工程においては、被加工材料を、切削加工補助潤滑材が付着した切削工具により、切削加工するか、切削加工補助潤滑材と被加工材料の密着体を、切削工具により切削加工する。このように切削加工補助潤滑材を用いることで、切削加工、特に、連続して加工を行う場合、切削工具の刃を含む切削工具表面と切削部内壁表面との間の潤滑性が高まり、切削工具の刃が切削する繊維や難削金属中の難削粒子の排出を容易化して、切削工具の刃との擦過頻度と度合いを軽減するため、切削工具の刃の摩耗が低減されると考えられる。この作用原理は、切削工具全般に通じる。
本実施形態の切削加工補助潤滑材が対象とする被加工材料としては、特に限定されないが、例えば、繊維強化複合材、難削金属材、又は繊維強化複合材と難削金属材との複合材料が挙げられる。
