Description

本発明は、試料の表面を切削することにより、試験切片を作製するための試料表面切削技術に関するものである。 The present invention relates to a sample surface cutting technique for producing a test section by cutting the surface of a sample.

各種試料の試験方法として、試料の表面を切削して薄い試験切片を作製し、当該試験切片を検査、観察する方法が知られている(例えば特許文献1)。このような試験切片の作製においては、目的とする切削対象範囲を高精度で正確に切削することが要求される。そのため、従来の試験切片作製は、専用の切削装置を使用した熟練作業者による手作業に委ねられることが多かった。 As a test method for various samples, a method is known in which the surface of a sample is cut to prepare a thin test section, and the test section is inspected and observed (for example, Patent Document 1). In the preparation of such a test section, it is required to cut the target cutting target range with high accuracy and accuracy. Therefore, the conventional test section preparation is often left to manual work by a skilled worker using a dedicated cutting device.

特開2006−334703号公報Japanese Unexamined Patent Publication No. 2006-334703

しかし、近年、熟練作業者の減少に伴い、試験切片作製の自動化が望まれている。 However, in recent years, as the number of skilled workers has decreased, automation of test section preparation has been desired.

前記に鑑み、本発明は、試験切片作製の自動化を可能とする試料表面切削方法、その試料表面切削方法を用いた試験切片の作製方法、及び、その試料表面切削方法を実施できる試料表面切削装置を提供することを目的とする。 In view of the above, the present invention provides a sample surface cutting method that enables automation of test section preparation, a test section preparation method that uses the sample surface cutting method, and a sample surface cutting device that can carry out the sample surface cutting method. The purpose is to provide.

前記の目的を達成するために、本発明に係る試料表面切削方法は、試料表面切削装置によって平板状の試料の表面を縦方向に切削すると共に先の切削ラインと後の切削ラインとが縦方向と直交する横方向に並ぶように複数回切削することにより、試料から試験切片を取り出すための試料表面切削方法であって、試料表面切削装置は、切刃と、試料を固定する試料台と、切刃と試料台とを相対的に移動させる駆動手段と、駆動手段の駆動を制御する制御手段とを備え、切刃と試料台とは、縦方向、横方向、及び、試料の表面に対して垂直な高さ方向のそれぞれに相対的に移動可能であり、制御手段を用いて試料台に対して切刃を、縦方向における前向き、及び、高さ方向における下向きに相対的に移動させることによって、試料の表面を切削する工程(D)と、制御手段を用いて試料台に対して切刃を、高さ方向における上向きに相対的に移動させる工程(E)と、制御手段を用いて試料台に対して切刃を、先の切削ライン上から後の切削ライン上まで相対的に移動させる工程(G)とを含む。 In order to achieve the above object, in the sample surface cutting method according to the present invention, the surface of a flat plate-shaped sample is cut in the vertical direction by a sample surface cutting device, and the front cutting line and the rear cutting line are in the vertical direction. This is a sample surface cutting method for taking out a test section from a sample by cutting the test section a plurality of times so as to be aligned in a horizontal direction orthogonal to the above. The sample surface cutting device includes a cutting edge, a sample table for fixing the sample, and a sample table. A driving means for relatively moving the cutting edge and the sample table and a control means for controlling the driving of the driving means are provided, and the cutting edge and the sample table are provided with respect to the vertical direction, the horizontal direction, and the surface of the sample. The cutting edge is relatively movable in each of the vertical height directions, and the cutting edge is relatively moved forward in the vertical direction and downward in the height direction with respect to the sample table by using a control means. A step (D) of cutting the surface of the sample, a step (E) of moving the cutting edge relative to the sample table with respect to the sample table by using the control means, and a step (E) using the control means. The step (G) of moving the cutting edge relative to the sample table from the first cutting line to the second cutting line is included.

本発明に係る試料表面切削方法によると、試料表面切削装置の制御手段を用いて、「試料台に対して切刃を、縦方向(切削ラインの延びる方向)における前向き(切削方向)、及び、高さ方向における下向きに相対的に移動させて、試料の表面を切削する」工程(D)と、「試料台に対して切刃を、高さ方向における上向きに相対的に移動させる」工程(E)と、「試料台に対して切刃を、先の切削ライン上から後の切削ライン上まで相対的に移動させる」工程(G)とを行う。このため、試料の表面を縦方向に切削すると共に先の切削ラインと後の切削ラインとが横方向に並ぶように自動で切削して試験切片を得ることが可能となる。従って、試料表面の切削中に作業者による操作が不要となるので、試料表面切削を簡単に行うことができる。 According to the sample surface cutting method according to the present invention, using the control means of the sample surface cutting device, "the cutting edge is oriented forward (cutting direction) in the vertical direction (direction in which the cutting line extends) with respect to the sample table, and A step (D) of "cutting the surface of the sample by moving it relatively downward in the height direction" and a step of "moving the cutting edge relatively upward in the height direction with respect to the sample table" (D). E) and the step (G) of "moving the cutting edge relative to the sample table from the previous cutting line to the later cutting line" are performed. Therefore, it is possible to obtain a test section by cutting the surface of the sample in the vertical direction and automatically cutting the front cutting line and the rear cutting line so as to be aligned in the horizontal direction. Therefore, since no operation by an operator is required during cutting of the sample surface, the sample surface can be easily cut.

本発明に係る試料表面切削方法において、工程(G)において、試料台に対して切刃を、先の切削ライン上から後の切削ライン上まで横方向に相対的に移動させ、制御手段を用いて試料台に対して切刃を、縦方向における後向きに相対的に移動させる工程(F)をさらに含み、工程(D)、工程(E)、工程(F)、工程(G)の順番に、又は、工程(D)、工程(E)、工程(G)、工程(F)の順番に、切削動作を繰り返してもよい。このようにすると、試料の表面の切削が常に「縦方向における前向き」という単一の向きで行われるため、切削中に切刃の向きを変更する構成が不必要になるので、コストを抑制できる。また、切刃の移動動作が単純化されるため、複雑な切刃の移動動作を要する場合と比べて、切削精度を向上させることができる。 In the sample surface cutting method according to the present invention, in step (G), the cutting edge is moved relative to the sample table in the lateral direction from the upper cutting line to the later cutting line, and a control means is used. Further includes a step (F) of moving the cutting edge relative to the sample table in the vertical direction, in the order of step (D), step (E), step (F), and step (G). Alternatively, the cutting operation may be repeated in the order of step (D), step (E), step (G), and step (F). In this way, since the surface of the sample is always cut in a single direction of "forward in the vertical direction", it is not necessary to change the direction of the cutting edge during cutting, so that the cost can be suppressed. .. Further, since the moving operation of the cutting edge is simplified, the cutting accuracy can be improved as compared with the case where a complicated moving operation of the cutting edge is required.

本発明に係る試料表面切削方法において、駆動手段は、切刃を縦方向に移動させる第1駆動手段と、切刃を高さ方向に移動させる第2駆動手段と、試料台を横方向に移動させる第3駆動手段とを有し、工程(D)において、切刃が前向き及び下向きに移動し、工程(E)において、切刃が上向きに移動し、工程(G)において、試料台が横方向に移動してもよい。このようにすると、切刃の移動動作が、切削に必要な縦方向及び高さ方向の2軸方向のみに限定されるため、切刃を3軸方向に移動動作させる場合と比べて、装置の制御機構を簡素化することができるので、コストを抑制できる。 In the sample surface cutting method according to the present invention, the driving means include a first driving means for moving the cutting edge in the vertical direction, a second driving means for moving the cutting edge in the height direction, and moving the sample base in the horizontal direction. In the step (D), the cutting edge moves forward and downward, in the step (E), the cutting edge moves upward, and in the step (G), the sample table moves laterally. You may move in the direction. In this way, the moving operation of the cutting edge is limited to only the biaxial directions in the vertical direction and the height direction required for cutting. Therefore, as compared with the case where the cutting edge is moved in the triaxial direction, the apparatus Since the control mechanism can be simplified, the cost can be suppressed.

本発明に係る試料表面切削方法において、試料表面切削装置は、試料の表面の傾斜を測定する傾斜測定手段と、試料の表面の傾斜を調整する傾斜調整手段とをさらに備え、工程(D)、工程(E)及び工程(G)よりも前に、試料を試料台に固定する工程(A)と、試料の表面の傾斜を測定する工程(B)と、試料の表面の傾斜を調整する工程(C)とをさらに含んでいてもよい。このようにすると、試料の表面の傾斜を調整した上で自動切削を行うことができるので、切削精度を向上させることができる。 In the sample surface cutting method according to the present invention, the sample surface cutting apparatus further includes an inclination measuring means for measuring the inclination of the surface of the sample and an inclination adjusting means for adjusting the inclination of the surface of the sample. Prior to the steps (E) and (G), a step (A) of fixing the sample on the sample table, a step (B) of measuring the inclination of the surface of the sample, and a step of adjusting the inclination of the surface of the sample. (C) may be further included. In this way, automatic cutting can be performed after adjusting the inclination of the surface of the sample, so that the cutting accuracy can be improved.

本発明に係る試験切片の作製方法は、前述の本発明に係る試料表面切削方法を用いて、試料の表面を切削した後に、試験切片を回収する工程を含む。 The method for producing a test section according to the present invention includes a step of recovering the test section after cutting the surface of the sample using the above-mentioned method for cutting the surface of the sample according to the present invention.

本発明に係る試験切片の作製方法によると、本発明に係る試料表面切削方法を用いて、試料の表面を切削するため、試験切片作製を自動化することができる。また、本発明に係る試験切片の作製方法によれば、試料表面から一定の厚みの試験切片を多量に回収することが可能となるので、試料表面から一定の厚みまでの範囲を対象とする試料分析が容易になる。 According to the test section preparation method according to the present invention, the sample surface cutting method according to the present invention is used to cut the surface of the sample, so that the test section preparation can be automated. Further, according to the method for producing a test section according to the present invention, a large amount of a test section having a certain thickness can be recovered from the sample surface, so that the sample covers a range from the sample surface to a certain thickness. Easy to analyze.

本実施形態の試料表面切削装置1においては、前後移動モータ12、垂直移動モータ18、左右移動モータ31の駆動は、例えばパソコン等のコンピュータを備える制御手段40によって自動的に制御される。制御手段40は、入力インタフェース41を通じて、縦方向変位計15、縦方向圧力検知器29、垂直変位計22及び垂直圧力検知器25で検出された情報を読み込み、当該情報に基づいて、第1出力インタフェース42を通じて前後移動モータ12及び垂直移動モータ18の駆動を制御すると共に第2出力インタフェース43を通じて左右移動モータ31の駆動を制御する。 In the sample surface cutting device 1 of the present embodiment, the driving of the front-rear moving motor 12, the vertical moving motor 18, and the left-right moving motor 31 is automatically controlled by a control means 40 including a computer such as a personal computer. The control means 40 reads the information detected by the vertical displacement meter 15, the vertical pressure detector 29, the vertical displacement meter 22, and the vertical pressure detector 25 through the input interface 41, and outputs the first output based on the information. The drive of the front-rear moving motor 12 and the vertical moving motor 18 is controlled through the interface 42, and the driving of the left-right moving motor 31 is controlled through the second output interface 43.

制御手段40は、切刃2の横方向変位(横方向移動距離)については、左右移動モータ31への駆動指令の移動距離を用いてもよいし、別途、横方向移動距離を測定するための横方向変位計を設け、当該変位計で検出された情報を用いてもよい。また、制御手段40は、切刃2の縦方向変位(縦方向移動距離)について、縦方向変位計15で検出された情報に代えて、前後移動モータ12への駆動指令の移動距離を用いてもよいし、切刃2の高さ方向変位(高さ方向移動距離)について、垂直変位計22で検出された情報に代えて、垂直移動モータ18への駆動指令の移動距離を用いてもよい。但し、試料3の切削時には、切刃2が試料3から受ける反力等により移動距離のブレが発生する可能性があるため、精度良く試料3を切削するためには、縦方向移動距離及び高さ方向移動距離については、変位計によって実際の移動距離を精密にモニタリングしながら、切削を行った方が良い。 The control means 40 may use the movement distance of the drive command to the left-right movement motor 31 for the lateral displacement (lateral movement distance) of the cutting edge 2, or separately for measuring the lateral movement distance. A lateral displacement meter may be provided and the information detected by the displacement meter may be used. Further, the control means 40 uses the moving distance of the drive command to the front-rear moving motor 12 instead of the information detected by the vertical displacement meter 15 for the vertical displacement (longitudinal moving distance) of the cutting edge 2. Alternatively, for the height displacement (height movement distance) of the cutting edge 2, the movement distance of the drive command to the vertical movement motor 18 may be used instead of the information detected by the vertical displacement meter 22. .. However, when cutting the sample 3, the movement distance may fluctuate due to the reaction force received by the cutting edge 2 from the sample 3, so that the vertical movement distance and the height are high in order to cut the sample 3 with high accuracy. Regarding the longitudinal movement distance, it is better to perform cutting while precisely monitoring the actual movement distance with a displacement meter.

制御手段40においては、コンピュータがプログラムを実行することによって、各機能が実施される。具体的には、制御手段40には、「試料台4に対して切刃2を、縦方向における前向き、及び、高さ方向における下向きに相対的に第1の距離だけ移動させる」第1の指令と、「試料台4に対して切刃2を、高さ方向における上向きに相対的に第2の距離だけ移動させる」第2の指令と、「試料台4に対して切刃2を、先の切削ライン上から後の切削ライン上まで相対的に第3の距離だけ移動させる」第3の指令とが少なくともプログラムされる。ここで、第3の指令が、「試料台4に対して切刃2を、先の切削ライン上から後の切削ライン上まで横方向に相対的に第3の距離だけ移動させる」指令である場合、制御手段40には、「試料台4に対して切刃2を、縦方向における後向きに相対的に第4の距離だけ移動させる」第4の指令がプログラムされていてもよい。ここで、「先の(後の)切削ライン上」には、実際に切削した(する)軌跡の上方のみでなく、その軌跡を延長した延長線上の上方も含まれるものとする。 In the control means 40, each function is executed by executing a program by a computer. Specifically, the control means 40 has a first "move the cutting edge 2 with respect to the sample table 4 by a first distance relative to the forward direction in the vertical direction and the downward direction in the height direction". The command and the second command "to move the cutting edge 2 relative to the sample table 4 by a second distance upward in the height direction" and "the cutting edge 2 to the sample table 4". At least a third command is programmed to "move a relative third distance from the first cutting line to the later cutting line." Here, the third command is a command to "move the cutting edge 2 relative to the sample table 4 by a third distance in the lateral direction from the upper cutting line to the later cutting line". In this case, the control means 40 may be programmed with a fourth command of "moving the cutting edge 2 relative to the sample table 4 in the rearward direction by a fourth distance". Here, it is assumed that "on the (rear) cutting line" includes not only the upper part of the actually cut locus but also the upper part on the extension line extending the locus.

尚、コンピュータは、プログラムに従って動作するプロセッサ、プログラムの実行に必要なデータを記憶するメモリ等を主なハードウェア構成として備える。プロセッサは、プログラムを実行することによって機能を実現することができれば、その種類は問わないが、例えば半導体集積回路(IC)又はLSI(large scale integration)を含む一つ又は複数の電子回路により構成されていてもよい。プログラムやデータは、コンピュータが読み取り可能なROM、光ディスク、ハードディスクドライブなどの非一時的記録媒体に記録される。プログラムやデータは、記録媒体に予め格納されていてもよいし、インターネット等を含む広域通信網を介して記録媒体に供給されてもよい。 The computer is provided with a processor that operates according to the program, a memory that stores data necessary for executing the program, and the like as a main hardware configuration.

The program or data may be stored in a recording medium in advance, or may be supplied to the recording medium via a wide area communication network including the Internet or the like.

<試料表面切削方法>
以下、図1、図2に示す試料表面切削装置1を用いた本実施形態の試料表面切削方法について、説明する。
<Sample surface cutting method>
Hereinafter, the sample surface cutting method of the present embodiment using the sample surface cutting device 1 shown in FIGS. 1 and 2 will be described.

本実施形態の試料表面切削方法においては、まず、試料3を試料台4上に固定する工程(A)を行う。例えば、試料台4は、試料3が載置される上面に試料吸引部(吸引孔)を有する箱状体からなり、当該箱状体の側部には吸引管(図示省略)が接続され、当該吸引管は真空ポンプ(図示省略)に接続されていてもよい。これにより、真空ポンプを動作させることにより、試料台4上において試料3が下方に吸引され、試料台4に試料3を固定することができる。このような固定方法に代えて、接着剤やホットメルト等を用いた化学的固定方法、又は、ボルト等を用いた物理的固定方法によって、試料3を試料台4上に固定してもよい。但し、固定精度や操作の簡便性の点では、前述の吸引固定が好ましい。 In the sample surface cutting method of the present embodiment, first, the step (A) of fixing the sample 3 on the sample table 4 is performed. For example, the sample table 4 is composed of a box-shaped body having a sample suction portion (suction hole) on the upper surface on which the sample 3 is placed, and a suction tube (not shown) is connected to the side portion of the box-shaped body. The suction pipe may be connected to a vacuum pump (not shown). As a result, by operating the vacuum pump, the sample 3 is sucked downward on the sample table 4, and the sample 3 can be fixed to the sample table 4. Instead of such a fixing method, the sample 3 may be fixed on the sample table 4 by a chemical fixing method using an adhesive, hot melt or the like, or a physical fixing method using a bolt or the like. However, the above-mentioned suction fixing is preferable from the viewpoint of fixing accuracy and ease of operation.

次に、試料3の表面の傾斜を測定する工程(B)を行う。工程(B)は、傾斜測定手段として、例えば、試料3の表面に接触させる圧子と、試料表面切削装置1における垂直変位計22及び垂直圧力検知器25とを用いて実施可能である。具体的には、切刃支持部11に切刃2に代えて圧子を取り付け、圧子を試料3に接触させながら、垂直圧力検知器25を用いて一定の荷重をかけた状態で圧子を動かし、垂直変位計22を用いて圧子の変位を連続的に検出する。これによって、試料3の表面の高さ情報を取得することできるので、試料3の表面の傾斜を測定することができる。また、試料3の表面の複数箇所において、垂直変位計22を用いて一定の高さ位置まで圧子を試料3の表面に押圧し、その際に圧子が受ける荷重を垂直圧力検知器25を用いて検出してもよい。これによって、一定の高さ位置で受ける荷重を複数点で比較することができるので、試料3の表面の傾斜を測定することができる。 Next, the step (B) of measuring the inclination of the surface of the sample 3 is performed. The step (B) can be carried out by using, for example, an indenter that comes into contact with the surface of the sample 3 and a vertical displacement meter 22 and a vertical pressure detector 25 in the sample surface cutting device 1 as the inclination measuring means. Specifically, an indenter is attached to the cutting edge support portion 11 instead of the cutting edge 2, and the indenter is moved while applying a constant load using the vertical pressure detector 25 while bringing the indenter into contact with the sample 3. The displacement of the indenter is continuously detected by using the vertical displacement meter 22. As a result, the height information of the surface of the sample 3 can be acquired, so that the inclination of the surface of the sample 3 can be measured. Further, at a plurality of locations on the surface of the sample 3, the indenter is pressed against the surface of the sample 3 to a certain height position using the vertical displacement meter 22, and the load received by the indenter at that time is applied by the vertical pressure detector 25. It may be detected. As a result, the load received at a constant height position can be compared at a plurality of points, so that the inclination of the surface of the sample 3 can be measured.

尚、図3に示すように、傾斜測定時には、圧子を少なくとも縦方向(a)及び横方向(b)の2方向に動かして傾斜測定を行うことが好ましく、傾斜測定精度をさらに向上させるためには、図4に示すように、圧子を縦方向(a)、横方向(b)及び斜め方向(c)の3方向に動かして傾斜測定を行うことがより好ましい。 As shown in FIG. 3, at the time of tilt measurement, it is preferable to move the indenter in at least two directions, the vertical direction (a) and the horizontal direction (b), to perform the tilt measurement, and in order to further improve the tilt measurement accuracy. More preferably, as shown in FIG. 4, the indenter is moved in three directions of the vertical direction (a), the horizontal direction (b), and the oblique direction (c) to perform the inclination measurement.

また、傾斜測定に用いる圧子の先端形状は、試料3と接触させた際に試料3を傷つけないように、曲面を有していることが好ましく、傾斜測定精度をさらに向上させるためには、圧子の先端形状は、球面状であることがより好ましい。図5は、傾斜測定に用いる圧子の一例の斜視図である。図5に示す圧子50の先端50aの形状は球面状である。 Further, the tip shape of the indenter used for the inclination measurement is preferably curved so as not to damage the sample 3 when it comes into contact with the sample 3, and in order to further improve the inclination measurement accuracy, the indenter is used. The tip shape of is more preferably spherical. FIG. 5 is a perspective view of an example of an indenter used for tilt measurement. The shape of the tip 50a of the indenter 50 shown in FIG. 5 is spherical.

次に、試料3の表面の傾斜を調整する工程(C)を行う。例えば、縦方向に試料台4の試料固定面を回転させる(回転軸は横方向に沿う)マイクロメータ(つまり縦方向傾斜調整手段36)と、横方向に試料台4の試料固定面を回転させる(回転軸は縦方向に沿う)マイクロメータ(つまり横方向傾斜調整手段37)とを用いて、試料3の角度調整が可能である。或いは、マイクロメータに代えて、アクチュエータ等の傾斜調整手段を用いてもよい。工程(C)を実施した後に、再度、工程(B)の傾斜測定を行い、試料3の表面が水平に近づいたことを確認してもよい。 Next, the step (C) of adjusting the inclination of the surface of the sample 3 is performed. For example, a micrometer (that is, the vertical inclination adjusting means 36) that rotates the sample fixing surface of the sample table 4 in the vertical direction (the rotation axis is along the horizontal direction) and the sample fixing surface of the sample table 4 are rotated in the horizontal direction. The angle of the sample 3 can be adjusted by using a micrometer (that is, the lateral inclination adjusting means 37) (the rotation axis is along the vertical direction). Alternatively, instead of the micrometer, an inclination adjusting means such as an actuator may be used. After performing the step (C), the inclination measurement of the step (B) may be performed again to confirm that the surface of the sample 3 is close to horizontal.

以上の工程(A)、(B)、(C)を行った後、試料表面切削装置1の切刃2による切削動作を開始する。図6は、試料台4に対する切刃2の相対的な移動方向を説明する図である。本実施形態では、試料台4に対して切刃2は、図6に示す3軸方向に沿って、つまり、切削ラインの延びる方向である縦方向、縦方向と直交する横方向(先の切削ラインと後の切削ラインとが並ぶ方向)、及び、高さ方向(試料3の表面に対して垂直な方向)のそれぞれに沿って、相対的に移動可能である。尚、縦方向のうち切削方向を「前向き」、その反対方向を「後向き」と称する。 After performing the above steps (A), (B), and (C), the cutting operation by the cutting edge 2 of the sample surface cutting device 1 is started. FIG. 6 is a diagram illustrating a relative moving direction of the cutting edge 2 with respect to the sample table 4. In the present embodiment, the cutting edge 2 has the cutting edge 2 with respect to the sample table 4 along the three-axis direction shown in FIG. It is relatively movable along each of the direction in which the line and the subsequent cutting line are lined up) and the height direction (direction perpendicular to the surface of the sample 3). Of the vertical directions, the cutting direction is referred to as "forward" and the opposite direction is referred to as "backward".

切削動作を開始する際に、作業者は、まず、制御手段40に対して、切削回数、縦方向の切削距離、高さ方向の切り込み深さ、及び、横方向の移動距離を設定する。横方向の移動距離は、切刃2の刃幅に合わせて設定されるが、横方向の移動距離を切刃2の刃幅と同等以下に設定すると、先の切削ラインと後の切削ラインとが一部重なるか又は隙間無く並列するので、試料3の表面から無駄なく試験切片を取り出すことができる。 When starting the cutting operation, the operator first sets the number of cuttings, the cutting distance in the vertical direction, the cutting depth in the height direction, and the moving distance in the horizontal direction for the control means 40. The lateral movement distance is set according to the blade width of the cutting blade 2, but if the lateral movement distance is set to be equal to or less than the blade width of the cutting blade 2, the front cutting line and the rear cutting line are set. Can be taken out from the surface of the sample 3 without waste because the test sections are partially overlapped or arranged in parallel without gaps.

次に、制御手段40が前後移動モータ12及び垂直移動モータ18を駆動して、切刃2を、縦方向における前向き、及び、高さ方向における下向きに移動させることによって、試料3の表面を自動切削する工程(D)を行う。具体的には、試料3が固定された試料台4を切削開始位置にセッティングした段階では、切刃2と試料3とは、高さ方向に離間しているので、まず、制御手段40が垂直移動モータ18を駆動して、切刃2を高さ方向における下向きに移動させて、試料3の表面における切削開始位置に切刃2を接触させる。この接触操作は、例えば垂直方向に切刃2を任意に移動させる機構を設けて、手動で行ってもよい。また、試料3と切刃2との接触確認は、例えば垂直圧力検知器25を用いて試料3と切刃2との接触を確認するか、或いは、試料3と切刃2とをビデオカメラ等で撮影しパソコン等に拡大表示することによって、試料3と切刃2との距離を作業者が目視で確認しながら行ってもよい。続いて、制御手段40が前後移動モータ12及び垂直移動モータ18を駆動して、設定した切り込み深さの位置に切刃2が達するまで、切刃2を、縦方向における前向き、及び、高さ方向における下向きに移動させる。続いて、切刃2が、設定した切り込み深さの位置に達すると、制御手段40は前後移動モータ12のみを駆動して、切刃2を高さ方向には変位させずに、設定した切削距離の位置まで切刃2を縦方向のみに変位させながら切削動作を行う。 Next, the control means 40 drives the front-rear moving motor 12 and the vertical moving motor 18 to move the cutting edge 2 forward in the vertical direction and downward in the height direction, thereby automatically moving the surface of the sample 3 in the vertical direction. Perform the cutting step (D). Specifically, at the stage where the sample table 4 to which the sample 3 is fixed is set at the cutting start position, the cutting edge 2 and the sample 3 are separated in the height direction, so that the control means 40 is vertical first. The moving motor 18 is driven to move the cutting edge 2 downward in the height direction so that the cutting edge 2 comes into contact with the cutting start position on the surface of the sample 3. This contact operation may be performed manually, for example, by providing a mechanism for arbitrarily moving the cutting edge 2 in the vertical direction. Further, to confirm the contact between the sample 3 and the cutting edge 2, for example, the contact between the sample 3 and the cutting edge 2 is confirmed by using the vertical pressure detector 25, or the sample 3 and the cutting edge 2 are connected to each other by a video camera or the like. The operator may visually check the distance between the sample 3 and the cutting edge 2 by taking a picture of the sample and displaying it on a personal computer or the like. Subsequently, the control means 40 drives the front-rear moving motor 12 and the vertical moving motor 18, and keeps the cutting edge 2 in the forward direction and the height in the vertical direction until the cutting edge 2 reaches the position of the set cutting depth. Move downward in the direction. Subsequently, when the cutting edge 2 reaches the position of the set cutting depth, the control means 40 drives only the front-rear moving motor 12 to perform the set cutting without displace the cutting edge 2 in the height direction. The cutting operation is performed while the cutting edge 2 is displaced only in the vertical direction to a position of a distance.

尚、工程(D)においては、縦方向圧力検知器29及び垂直圧力検知器25を用いて、切刃2の縦方向圧力及び垂直方向圧力を検知してもよい。このようにすると、切削状況をモニタリングできるため、試料3の硬度等に起因する影響によって、切り込み深さの設定値に対するばらつきが発生しているかどうかを知ることができる。切り込み深さに無視できないばらつきが発生した場合、工程(D)を中断して、工程(B)、(C)を再度行ってもよい。 In the step (D), the vertical pressure detector 29 and the vertical pressure detector 25 may be used to detect the vertical pressure and the vertical pressure of the cutting edge 2. By doing so, since the cutting state can be monitored, it is possible to know whether or not the set value of the cutting depth is varied due to the influence caused by the hardness of the sample 3. If there is a non-negligible variation in the cutting depth, the step (D) may be interrupted and the steps (B) and (C) may be repeated.

次に、制御手段40が垂直移動モータ18を駆動して、切刃2を高さ方向における上向きに移動させる工程(E)を行う。このとき、制御手段40が垂直移動モータ18と共に前後移動モータ12を駆動して、切刃2を高さ方向における上向きに移動させると同時に縦方向における前向きに移動させると、試料3から試験切片を切り離すことができるので、試験切片の回収が容易になる。また、切刃2が試料3の表面の高さまで移動した後は、制御手段40が垂直移動モータ18を駆動して、切刃2をさらに上向きに移動させて、切刃2と試料3とを高さ方向に離間させてもよい。 Next, the control means 40 drives the vertical movement motor 18 to move the cutting edge 2 upward in the height direction (E). At this time, when the control means 40 drives the front-rear moving motor 12 together with the vertical moving motor 18 to move the cutting edge 2 upward in the height direction and at the same time forward in the vertical direction, the test section is separated from the sample 3. Since it can be separated, the test section can be easily collected. After the cutting edge 2 has moved to the height of the surface of the sample 3, the control means 40 drives the vertical movement motor 18 to move the cutting edge 2 further upward to move the cutting edge 2 and the sample 3 together. It may be separated in the height direction.

次に、制御手段40が前後移動モータ12を駆動して、切刃2が前述の切削開始位置に戻るまで、切刃2を縦方向における後向きに移動させる工程(F)を行う。ここで、試料切削時間を短縮するために、工程(D)における切刃2の動作速度(切削動作速度)と比べて、工程(F)における切刃2の動作速度(戻り移動速度)の方を大きくしてもよい。また、切刃2を前述の切削開始位置まで戻す際に、切削開始位置の直前つまり切刃2の停止位置の直前で戻り移動速度を小さくしてもよい。このようにすると、切刃2を大きい戻り移動速度から切削開始位置で急停止させた場合に生じる切刃2の位置ずれを防止することができる。 Next, the step (F) is performed in which the control means 40 drives the front-rear moving motor 12 to move the cutting edge 2 backward in the vertical direction until the cutting edge 2 returns to the above-mentioned cutting start position. Here, in order to shorten the sample cutting time, the operating speed (returning moving speed) of the cutting blade 2 in the process (F) is higher than the operating speed (cutting operating speed) of the cutting blade 2 in the process (D). May be increased. Further, when returning the cutting edge 2 to the above-mentioned cutting start position, the return moving speed may be reduced immediately before the cutting start position, that is, immediately before the stop position of the cutting edge 2. By doing so, it is possible to prevent the misalignment of the cutting edge 2 that occurs when the cutting edge 2 is suddenly stopped at the cutting start position from a large return moving speed.

次に、制御手段40が左右移動モータ31を駆動して、切刃2が次回の切削ライン上に位置するように、試料台4を横方向に移動させる工程(G)を行う。すなわち、工程(G)において、試料台4に対して切刃2は、先(前回)の切削ライン上から後(次回)の切削ライン上まで横方向に相対的に移動する。 Next, a step (G) is performed in which the control means 40 drives the left-right movement motor 31 to move the sample table 4 in the lateral direction so that the cutting edge 2 is located on the next cutting line. That is, in the step (G), the cutting edge 2 moves relative to the sample table 4 in the lateral direction from the previous (previous) cutting line to the subsequent (next) cutting line.

本実施形態の試料表面切削方法においては、予め設定した切削回数に達するまで、工程(D)、(E)、(F)、(G)の切削動作が繰り返し自動で実施される。その後、例えば、ピンセット等を使用して、作業者が試料3の上に残る複数の試験切片を回収することにより、試験切片の作製が完了する。試験切片の回収は、自動で行ってもよい。 In the sample surface cutting method of the present embodiment, the cutting operations of steps (D), (E), (F), and (G) are automatically repeated until the preset number of cuttings is reached. Then, for example, using tweezers or the like, the operator collects a plurality of test sections remaining on the sample 3, and the preparation of the test sections is completed. The test section may be collected automatically.

図7、図8は、本実施形態の試料表面切削方法における試料台4に対する切刃2の相対的な移動軌跡の一例を示し、図7は、試料3を上から見た軌跡を示し、図8は、試料3を横から見た軌跡を示す。尚、図7、図8において、図1、図2に示す試料表面切削装置1と同じ構成要素には同じ符号を付す。また、図7、図8において、切刃2の相対的な移動軌跡を矢印(実線又は破線)で示し、各矢印には該当する工程(D、E、F、G)を付記する。 7 and 8 show an example of the relative movement locus of the cutting edge 2 with respect to the sample table 4 in the sample surface cutting method of the present embodiment, and FIG. 7 shows a locus of the sample 3 viewed from above. Reference numeral 8 shows a trajectory of the sample 3 as viewed from the side. In FIGS. 7 and 8, the same components as those of the sample surface cutting apparatus 1 shown in FIGS. 1 and 2 are designated by the same reference numerals. Further, in FIGS. 7 and 8, the relative movement locus of the cutting edge 2 is indicated by an arrow (solid line or broken line), and the corresponding steps (D, E, F, G) are added to each arrow.

<実施形態の効果>
以上に説明したように、本実施形態の試料表面切削方法によると、試料表面切削装置1の制御手段40を用いて、「切刃2を、縦方向(切削ラインの延びる方向)における前向き(切削方向)、及び、高さ方向における下向きに相対的に移動させて、試料3の表面を切削する」工程(D)と、「切刃2を高さ方向における上向きに移動させる」工程(E)と、「切刃2が先の切削ライン上から後の切削ライン上まで相対的に移動するように、試料台4を横方向に移動させる」工程(G)とを行う。このため、試料3の表面を縦方向に切削すると共に先の切削ラインと後の切削ラインとが横方向に並ぶように自動で切削して試験切片を得ることが可能となる。従って、試料3の表面の切削中に作業者による操作が不要となるので、試料表面切削を簡単に行うことができる。
<Effect of embodiment>
As described above, according to the sample surface cutting method of the present embodiment, the control means 40 of the sample surface cutting device 1 is used to "cut the cutting edge 2 forward (cutting in the direction in which the cutting line extends). Direction) and the step of "cutting the surface of the sample 3 by moving it relatively downward in the height direction" (D) and the step (E) of "moving the cutting edge 2 upward in the height direction". And the step (G) of "moving the sample table 4 in the lateral direction so that the cutting edge 2 moves relatively from the cutting line before to the cutting line after" is performed. Therefore, it is possible to obtain a test section by cutting the surface of the sample 3 in the vertical direction and automatically cutting the front cutting line and the rear cutting line so as to be aligned in the horizontal direction. Therefore, since no operation by an operator is required during cutting of the surface of the sample 3, the surface of the sample can be easily cut.

また、本実施形態の試料表面切削方法において、制御手段40を用いて、切刃2を縦方向における後向きに相対的に移動させる工程(F)をさらに含み、工程(D)、工程(E)、工程(F)、工程(G)の順番に、切削動作を繰り返すと、試料3の表面の切削が常に「縦方向における前向き」という単一の向きで行われる。このため、切削中に切刃2の向きを変更する構成が不必要になるので、コストを抑制できる。また、切刃2の移動動作が単純化されるため、複雑な切刃の移動動作を要する場合と比べて、切削精度を向上させることができる。 Further, in the sample surface cutting method of the present embodiment, the step (F) of moving the cutting edge 2 relatively backward in the vertical direction by using the control means 40 is further included, and the steps (D) and (E) are included. When the cutting operation is repeated in the order of step (F) and step (G), the surface of the sample 3 is always cut in a single direction of "forward in the vertical direction". Therefore, it is not necessary to change the direction of the cutting edge 2 during cutting, so that the cost can be suppressed. Further, since the moving operation of the cutting edge 2 is simplified, the cutting accuracy can be improved as compared with the case where a complicated moving operation of the cutting edge is required.

また、本実施形態の試料表面切削方法において、試料表面切削装置1は、切刃2と試料台4とを相対的に移動させる駆動手段として、切刃2を縦方向に移動させる前後移動モータ12と、切刃2を高さ方向に移動させる垂直移動モータ18と、試料台4を横方向に移動させる左右移動モータ31とを有し、工程(D)において、切刃2が前向き及び下向きに移動し、工程(E)において、切刃が上向きに移動し、工程(G)において、試料台4が横方向に移動すると、切刃2の移動動作が、切削に必要な縦方向及び高さ方向の2軸方向のみに限定される。このため、切刃を3軸方向に移動動作させる場合と比べて、試料表面切削装置1の制御機構を簡素化することができるので、コストを抑制できる。 Further, in the sample surface cutting method of the present embodiment, the sample surface cutting device 1 is a front-rear moving motor 12 that moves the cutting edge 2 in the vertical direction as a driving means for relatively moving the cutting edge 2 and the sample base 4. A vertical moving motor 18 for moving the cutting edge 2 in the height direction and a left-right moving motor 31 for moving the sample base 4 in the lateral direction. In the step (D), the cutting edge 2 is directed forward and downward. When the cutting edge moves upward in the step (E) and the sample table 4 moves in the lateral direction in the step (G), the moving operation of the cutting edge 2 moves in the vertical direction and the height required for cutting. It is limited to the biaxial direction of the direction. Therefore, the control mechanism of the sample surface cutting device 1 can be simplified as compared with the case where the cutting edge is moved in the three axial directions, so that the cost can be suppressed.

また、本実施形態の試料表面切削方法において、試料表面切削装置1が、試料3の表面の傾斜を測定する傾斜測定手段と、試料3の表面の傾斜を調整する傾斜調整手段(具体的には縦方向傾斜調整手段36及び横方向傾斜調整手段37)とをさらに備え、工程(D)、工程(E)及び工程(G)よりも前に、試料3を試料台4に固定する工程(A)と、試料3の表面の傾斜を測定する工程(B)と、試料3の表面の傾斜を調整する工程(C)とをさらに含むと、試料3の表面の傾斜を調整した上で自動切削を行うことができるので、切削精度を向上させることができる。 Further, in the sample surface cutting method of the present embodiment, the sample surface cutting device 1 has an inclination measuring means for measuring the inclination of the surface of the sample 3 and an inclination adjusting means for adjusting the inclination of the surface of the sample 3 (specifically, A step (A) of fixing the sample 3 to the sample table 4 prior to the step (D), the step (E) and the step (G), further including the vertical tilt adjusting means 36 and the horizontal tilt adjusting means 37). ), The step of measuring the inclination of the surface of the sample 3 (B), and the step of adjusting the inclination of the surface of the sample 3 (C) are further included, and the automatic cutting is performed after adjusting the inclination of the surface of the sample 3. Therefore, the cutting accuracy can be improved.

以上に説明した本実施形態の試料表面切削方法を用いて試料3の表面を切削した後に、試験切片を回収する工程を含む試験切片の作製方法によると、試験切片作製を自動化することができる。また、この試験切片の作製方法によれば、試料3の表面から一定の厚みの試験切片を多量に回収することが可能となるので、試料3の表面から一定の厚みまでの範囲を対象とする試料分析が容易になる。 According to the test section preparation method including the step of collecting the test section after cutting the surface of the sample 3 using the sample surface cutting method of the present embodiment described above, the test section preparation can be automated. Further, according to this method for preparing a test section, a large amount of a test section having a certain thickness can be recovered from the surface of the sample 3, and therefore, the range from the surface of the sample 3 to a certain thickness is targeted. Sample analysis becomes easier.

本実施形態の試料表面切削装置1によると、本実施形態の試料表面切削方法について説明したように、試料3の表面を縦方向に切削すると共に先の切削ラインと後の切削ラインとが横方向に並ぶように自動で切削して試験切片を得ることが可能となる。従って、試料3の表面の切削中に作業者の操作が不要となるので、試料表面切削を簡単に行うことができる。 According to the sample surface cutting device 1 of the present embodiment, as described in the sample surface cutting method of the present embodiment, the surface of the sample 3 is cut in the vertical direction, and the front cutting line and the rear cutting line are in the horizontal direction. It is possible to obtain a test section by automatically cutting so as to line up with. Therefore, since no operator's operation is required during cutting of the surface of the sample 3, the surface of the sample can be easily cut.

(Modification example 1)
FIG. 9 is a diagram showing a relative movement locus of the cutting edge 2 with respect to the sample table 4 in the sample surface cutting method according to the first modification. Note that FIG. 9 shows a trajectory of the sample 3 as viewed from above, and the same components as those in the embodiment shown in FIG. 7 are designated by the same reference numerals.

前記実施形態では、図7に示すように、工程(D)、工程(E)、工程(G)、工程(F)の順番に切削動作を繰り返したのに対して、本変形例の試料表面切削方法では、図9に示すように、工程(D)、工程(E)、工程(G)、工程(F)の順番に切削動作を繰り返す。すなわち、前記実施形態では、先の切削ライン上で工程(F)の戻り移動を行ったが、本変形例では、後の切削ライン上で工程(F)の戻り移動を行う。 In the above embodiment, as shown in FIG. 7, the cutting operation is repeated in the order of step (D), step (E), step (G), and step (F), whereas the sample surface of this modification is obtained. In the cutting method, as shown in FIG. 9, the cutting operation is repeated in the order of step (D), step (E), step (G), and step (F). That is, in the above-described embodiment, the return movement of the step (F) is performed on the previous cutting line, but in this modification, the return movement of the step (F) is performed on the later cutting line.

以上に説明した本変形例においても、前記実施形態と同様の効果を得ることができる。 Also in the present modification described above, the same effect as that of the above-described embodiment can be obtained.

(変形例2)
図10は、変形例2に係る試料表面切削方法における試料台4に対する切刃2の相対的な移動軌跡を示す図である。尚、図10は、試料3を上から見た軌跡を示し、図7に示す前記実施形態と同じ構成要素には同じ符号を付す。
(Modification 2)
FIG. 10 is a diagram showing a relative movement locus of the cutting edge 2 with respect to the sample table 4 in the sample surface cutting method according to the modified example 2. Note that FIG. 10 shows a trajectory of the sample 3 as viewed from above, and the same components as those in the embodiment shown in FIG. 7 are designated by the same reference numerals.

本変形例が前記実施形態と異なっている点は、切刃2若しくは試料台4を180°回転させる機構を設けるか、又は、切刃2が縦方向における前向き及び後向きの両方で試料3を切削可能に形成されていることである。これにより、図10に示すように、工程(F)の戻り移動を行うことなく、切削動作を繰り返すことができる。 The difference between this modification and the above embodiment is that a mechanism for rotating the cutting edge 2 or the sample base 4 by 180 ° is provided, or the cutting edge 2 cuts the sample 3 both forward and backward in the vertical direction. It is possible to form. As a result, as shown in FIG. 10, the cutting operation can be repeated without performing the return movement in the step (F).

以上に説明した本変形例においても、前記実施形態と同様の効果を得ることができるが、試料表面切削装置1の機構や切刃2の構造が複雑化する点で前記実施形態よりもコストが増大する場合がある。 In the present modification described above, the same effect as that of the above-described embodiment can be obtained, but the cost is higher than that of the above-described embodiment in that the mechanism of the sample surface cutting device 1 and the structure of the cutting edge 2 are complicated. May increase.

(変形例3)
図11は、変形例3に係る試料表面切削方法における試料台4に対する切刃2の相対的な移動軌跡を示す図である。尚、図11は、試料3を上から見た軌跡を示し、図7に示す前記実施形態と同じ構成要素には同じ符号を付す。
(Modification example 3)
FIG. 11 is a diagram showing a relative movement locus of the cutting edge 2 with respect to the sample table 4 in the sample surface cutting method according to the modified example 3. Note that FIG. 11 shows a trajectory of the sample 3 as viewed from above, and the same components as those in the embodiment shown in FIG. 7 are designated by the same reference numerals.

本変形例が前記実施形態と異なっている点は、図11に示すように、「試料台4に対して切刃2を、先の切削ライン上から後の切削ライン上まで相対的に移動させる」工程(G)において、工程(F)の戻り移動を同時に実施することである。 The difference between this modification and the embodiment is that, as shown in FIG. 11, "the cutting edge 2 is relatively moved from the first cutting line to the later cutting line with respect to the sample table 4." In step (G), the return movement of step (F) is carried out at the same time.

以上に説明した本変形例においても、前記実施形態と同様の効果を得ることができるが、試料台4に対して切刃2を3軸(縦方向、横方向、高さ方向)以外の方向に相対的に移動させるため、前記実施形態と比べて、切削精度が低下する場合がある。 In the present modification described above, the same effect as that of the above-described embodiment can be obtained, but the cutting edge 2 is placed in a direction other than the three axes (vertical direction, horizontal direction, height direction) with respect to the sample table 4. Since it is moved relative to the above-described embodiment, the cutting accuracy may be lowered as compared with the above-described embodiment.

(その他の実施形態)
前記実施形態では、試料表面切削装置1は、切刃2と試料台4とを相対的に移動させる駆動手段として、切刃2を縦方向に移動させる前後移動モータ12と、切刃2を高さ方向に移動させる垂直移動モータ18と、試料台4を横方向に移動させる左右移動モータ31とを有した。しかし、本発明では、切刃2と試料台4とは、少なくとも縦方向、横方向、高さ方向の3軸方向に相対的に移動可能であれば、切刃2及び試料台4のいずれが移動してもよい。
