Abstract

<P>PROBLEM TO BE SOLVED: To precisely carry out processing by both of forward movement and reverse movement, and the processing of a curve, etc. without causing the positional dislocation of a cutting blade even if changing the cutting direction of the cutting tool. <P>SOLUTION: A cutting tool holder 23 is mounted to the tip of a main spindle (C shaft) 20 through a cross coupler 22 as a centering means. The cutting tool holder 23 is devised to mount the cutting tool 30 on it so as to substantially position the top 30A of the cutting blade on the axis of the spindle (C shaft) 20. The cross coupler 22 precisely positions the top 30A on the axis of the main spindle (C shaft) 20 by moving the cutting tool holder 23 by an adjusting screw 27 and an the other adjusting screw arranged at a position orthogonal to it within a flat surface perpendicular to the axis of the main spindle (C shaft) 20. Consequently, the top 30A is constantly located on the axis of the main spindle (C shaft) 20 even when the direction of the cutting tool 30 is changed by rotating the main spindle (C shaft) 20, and accordingly, precise processing is carried out by controlling the position of the main spindle (C shaft) 20. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

この発明は、例えばプレーナ型工作機械により、バイトに対し相対的にワークをＸＹ平面上で往復動させ、該ワークの表面に、例えば液晶表示パネル、プラズマ表示パネルなどの薄型表示パネル用の導光板や偏光板、拡散板などの微細構造用の物品やその物品を製作するための金型に必要な、微細な多数の溝等を切削加工するバイト加工装置に係り、特にバイトの切削方向の向きを変えてワークを加工するバイト加工装置に関する。   The present invention is a light guide plate for a thin display panel such as a liquid crystal display panel or a plasma display panel, for example, by reciprocating a work on an XY plane relative to a cutting tool with a planar machine tool. In particular, it relates to a tool for cutting a large number of fine grooves required for a fine structure article such as a polarizing plate, a polarizing plate, and a mold for producing the article, and in particular the direction of the cutting direction of the tool The present invention relates to a tool for processing a workpiece by changing the workpiece.

上記のような微細構造用の物品や金型において、例えば金型を例にとると、金型は、微細な多数の溝を有しており、その加工には、バイトを用い、このバイトに対し相対的に金型の素材であるワークをＸＹ平面上で往復動させて行われている（例えば、特許文献１参照）。   In the above-described fine structure article or mold, for example, when the mold is taken as an example, the mold has a large number of fine grooves, and a cutting tool is used for the processing. On the other hand, it is performed by reciprocating a workpiece, which is a material of a mold, on the XY plane (see, for example, Patent Document 1).

上記のようにバイトに対し相対的にワークをＸＹ平面上で往復動させて行うバイト加工には、一般的にプレーナ型工作機械が用いられる。このプレーナ型工作機械は、ＸＹ平面上でワークを例えばＸ軸方向に往復動させ、バイトは、ＸＹ平面に垂直なＺ軸方向の位置を所定値に保ち、Ｘ軸方向には移動させずにＹ軸方向の位置をワークの各往復動毎に変化させて行う。   As described above, a planar machine tool is generally used for the bite machining performed by reciprocating the workpiece on the XY plane relative to the bite. This planar machine tool reciprocates the workpiece on the XY plane, for example, in the X-axis direction, and the cutting tool maintains the position in the Z-axis direction perpendicular to the XY plane at a predetermined value and does not move in the X-axis direction. The position in the Y-axis direction is changed for each reciprocation of the workpiece.

バイトは、すくい角や逃げ角を有し、いわゆる切削加工のための向きがあるため、ワークの往復動のうちの往動か復動かのいずれか一方でしか加工することができない。ところで、上記の金型は、微細な多数の溝を加工する必要があるため、ワークの往復動の回数は膨大なものとなり、その加工には長時間を要する。
特開２００５−２７９９１８号公報 Since the cutting tool has a rake angle and a clearance angle and has a so-called cutting direction, it can be processed by only one of the forward and backward movements of the reciprocating movement of the workpiece. By the way, since it is necessary to process a large number of fine grooves, the above-described mold requires a tremendous number of reciprocating motions of the workpiece, and the processing takes a long time.
JP-A-2005-279918

上記加工時間を短縮するためには、往動か復動のいずれか一方のみでなく、両方で加工できることが望ましい。このためにはバイトの切削方向の向きを変える必要がある。しかしながら、バイトの向きを変えることにより、バイトの切れ刃部が例えば上記Ｙ軸方向等に変化すると、ワークの各往復動毎にバイトの切れ刃部の位置が所定の位置からずれ所望の加工を行うことができない。   In order to shorten the processing time, it is desirable that the processing can be performed not only in one of the forward and backward movements but also in both. For this purpose, it is necessary to change the cutting direction of the cutting tool. However, by changing the direction of the cutting tool, if the cutting edge of the cutting tool changes in the Y-axis direction or the like, for example, the position of the cutting edge of the cutting tool deviates from a predetermined position for each reciprocating movement of the workpiece. I can't do it.

また、往動中又は復動中にバイトの向きを変えつつ所定の曲線を描くように切削加工を行う場合にも、該バイトがその向きの変化に伴って位置ずれを生じると、所定の曲線を描くように加工することができない。   In addition, when cutting is performed so as to draw a predetermined curve while changing the direction of the cutting tool during the forward movement or the backward movement, if the cutting position of the cutting tool is caused by the change of the direction, the predetermined curve is generated. Can not be processed to draw.

この発明は、バイトの切削方向の向きを変えても切れ刃部が所定の位置に保たれ、上記往動及び復動の両方での加工や曲線の加工等を的確に行うことのできるバイト加工装置を提供することを目的としている。   The present invention provides a cutting tool capable of accurately performing the processing in both the forward movement and the backward movement, the processing of a curve, etc., even if the cutting direction of the cutting tool is changed. The object is to provide a device.

上記目的を達成するためのこの発明は、バイトの切削方向の向きを変えてワークを加工するバイト加工装置において、前記バイトの切削方向の向きを変化可能に該バイトを取り付けるための回転軸と、この回転軸の先端に前記バイトを着脱可能に取り付けるためのバイトホルダと、このバイトホルダと前記回転軸との間に設けられ前記バイトの切れ刃部を前記回転軸の軸芯上に位置付けするための調芯手段とを備え、前記ワークに対する前記回転軸の位置を制御して加工を行うことを特徴としている。   To achieve the above object, the present invention provides a cutting tool for processing a workpiece by changing the direction of the cutting direction of the cutting tool, and a rotating shaft for mounting the cutting tool so that the direction of the cutting direction of the cutting tool can be changed, A tool holder for removably attaching the tool to the tip of the rotating shaft, and a cutting edge portion of the tool provided between the tool holder and the rotating shaft to position the tool on the axis of the rotating shaft. And a centering means for controlling the position of the rotary shaft with respect to the workpiece.

なお、前記調芯手段は、上下の面に互いに直行する突起を有する十字継手を用いることができる。   The alignment means may be a cross joint having protrusions that are perpendicular to each other on the upper and lower surfaces.

この発明は、上記のようにバイトホルダと回転軸との間に調芯手段を設け、バイトの切れ刃部を回転軸の軸芯上に位置付けするようにしたため、バイトの切削方向の向きを変えても切れ刃部を常に回転軸の軸芯上に位置させることができ、これにより前記回転軸の位置を制御するのみで、前述した往動及び復動の両方での加工や曲線の加工等を的確に行うことができる効果が得られる。   In the present invention, as described above, the centering means is provided between the tool holder and the rotary shaft, and the cutting blade portion of the tool is positioned on the shaft core of the rotary shaft, so that the direction of the cutting direction of the tool is changed. However, the cutting edge portion can always be positioned on the axis of the rotating shaft, and by this, only the position of the rotating shaft is controlled, the above-described processing in both forward and backward movements, curve processing, etc. The effect that can be performed accurately is obtained.

以下図1ないし図６により、この発明の一実施形態例について説明する。図1は、この発明をプレーナ型工作機械に適用した例を示す概要正面図であり、図２は、図１の右側面図である。図１及び図２において、１０はベッド、１１はテーブルである。テーブル１１は、図示しないリニアモータ等の駆動装置によりベッド１０上を図１においては紙面と垂直方向へ、また、図２においては左右方向（Ｘ軸方向）へテーブル１１の上面と平行に所定の範囲を所定の速度で移動すべく搭載されている。テーブル１１上には真空チャック１２が取り付けられ、この真空チャック１２により平板状のワーク１３が吸着保持される。   An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a schematic front view showing an example in which the present invention is applied to a planar machine tool, and FIG. 2 is a right side view of FIG. In FIG.1 and FIG.2, 10 is a bed and 11 is a table. The table 11 is placed on the bed 10 in a direction perpendicular to the paper surface in FIG. 1 and in a horizontal direction (X-axis direction) in FIG. 2 in parallel with the upper surface of the table 11 by a driving device such as a linear motor (not shown). It is mounted to move the range at a predetermined speed. A vacuum chuck 12 is attached on the table 11, and a flat work 13 is sucked and held by the vacuum chuck 12.

ベッド１０の両側面にはコラム１４、１４が立ち上げられ、両コラム１４の上端には、図１においては左右方向へ、また、図２においては紙面と垂直方向（Ｙ軸方向）へテーブル１１の上面と平行に伸びるクロスレール１５が掛け渡して取り付けられている。このクロスレール１５には、サドル１６が図示しないリニアモータ等の駆動装置によりＹ軸方向へ移動可能かつ所定位置に停止可能に搭載されている。   Columns 14 and 14 are raised on both side surfaces of the bed 10, and a table 11 is provided at the upper end of both columns 14 in the left-right direction in FIG. 1 and in the direction perpendicular to the paper surface (Y-axis direction) in FIG. A cross rail 15 extending in parallel with the upper surface of the cable is attached to the cross rail 15. A saddle 16 is mounted on the cross rail 15 so as to be movable in the Y-axis direction and stopped at a predetermined position by a driving device such as a linear motor (not shown).

サドル１６には、図１及び図２において上下方向すなわちテーブル１１の上面（ＸＹ平面）と垂直方向（Ｚ軸方向）へ移動可能に昇降台１７が搭載されている。この昇降台１７は、サドル１６に取り付けられたサーボモータ１８、又はテーブル１１及びサドル１６と同様に図示しないリニアモータ等の駆動装置により昇降されると共に所定位置に停止される。   The saddle 16 is mounted with a lifting platform 17 that can move in the vertical direction, that is, in the vertical direction (Z-axis direction) with respect to the upper surface (XY plane) of the table 11 in FIGS. The lift 17 is lifted and lowered by a drive device such as a linear motor (not shown) similar to the servo motor 18 attached to the saddle 16 or the table 11 and the saddle 16 and stopped at a predetermined position.

昇降台１７にはバイト回転台１９が取り付けられている。バイト回転台１９には、Ｚ軸と平行に伸びる回転軸としての主軸（Ｃ軸）２０が回転可能に取り付けられ、この主軸（Ｃ軸）２０は、バイト回転台１９に取り付けられたサーボモータ２１により後述するように１８０°の回転を与えられる。   A tool turn table 19 is attached to the lifting table 17. A main shaft (C axis) 20 as a rotation axis extending in parallel with the Z axis is rotatably attached to the tool rotating table 19, and the main shaft (C axis) 20 is a servo motor 21 attached to the tool rotating table 19. To give a rotation of 180 ° as will be described later.

主軸（Ｃ軸）２０の先端には、図３及び図４に示すように、調芯手段としての十字継手２２を介してバイトホルダ２３がボルト２４により取り付けられている。十字継手２２は、上下の面に沿って互いに直行して伸びる突起２２Ａ、２２Ｂを有し、これらの突起２２Ａ、２２Ｂは、主軸（Ｃ軸）２０の先端面とバイトホルダ２３の後端面に設けられた溝２５、２６にそれぞれスライド可能に係合されている。主軸（Ｃ軸）２０とバイトホルダ２３には、突起２２Ａ、２２Ｂと平行に配置されて十字継手２２の外周面に当接する調整ねじ２７、２８が設けられている。   As shown in FIGS. 3 and 4, a bite holder 23 is attached to the tip of the main shaft (C-axis) 20 with a bolt 24 via a cross joint 22 as an alignment means. The cross joint 22 has protrusions 22A and 22B extending perpendicularly to each other along the upper and lower surfaces, and these protrusions 22A and 22B are provided on the front end surface of the main shaft (C axis) 20 and the rear end surface of the bite holder 23. The grooves 25 and 26 are slidably engaged with each other. The main shaft (C-axis) 20 and the tool holder 23 are provided with adjusting screws 27 and 28 that are arranged in parallel with the protrusions 22A and 22B and come into contact with the outer peripheral surface of the cross joint 22.

バイトホルダ２３は、上下に伸びる溝２９にバイト３０を嵌入し、バイト３０は押え板３１とボルト３２により締め付け固定される。バイト３０は、図３に示すように、その先端の正面から見た切れ刃部の形状が図６（イ）、（ロ）に示す加工溝１３Ａの形状に対応した山形をしており、この山形の頂点３０Ａは、上記調整ねじ２７、２８により十字継手２２を介してバイトホルダ２３を主軸（Ｃ軸）２０の軸心と直行する方向へ移動させて調芯することにより、図３及び図４に示すように、主軸（Ｃ軸）２０の軸心上に位置付けされる。なお、図３及び図４に示すバイト３０は、図４に示すように、すくい角α（零ないし負の場合もある）と逃げ角βを有し、バイト３０が図４において右から左へ移動して加工する例を示している。   The cutting tool holder 23 is inserted into a groove 29 extending vertically, and the cutting tool 30 is fastened and fixed by a presser plate 31 and a bolt 32. As shown in FIG. 3, the cutting tool 30 has a chevron shape corresponding to the shape of the machining groove 13A shown in FIGS. 6 (a) and 6 (b). The apex 30A of the chevron is aligned by moving the tool holder 23 in the direction perpendicular to the axis of the main shaft (C-axis) 20 through the cross joint 22 by the adjusting screws 27 and 28, thereby adjusting the center. As shown in FIG. 4, it is positioned on the axis of the main axis (C axis) 20. The cutting tool 30 shown in FIGS. 3 and 4 has a rake angle α (which may be zero or negative) and a clearance angle β as shown in FIG. 4, and the cutting tool 30 moves from right to left in FIG. An example of moving and processing is shown.

次いでこの装置の作用について説明する。まず、サーボモータ１８によりバイト３０のＺ軸方向位置を加工溝１３Ａの深さに合わせるべく図１及び図２に示す昇降台１７の高さ位置を定めると共に、図示しない駆動装置によりサドル１６を移動させて主軸（Ｃ軸）２０のＹ軸方向位置を最初の加工溝１３Ａの加工位置に位置付けする。   Next, the operation of this apparatus will be described. First, in order to adjust the position of the cutting tool 30 in the Z-axis direction to the depth of the machining groove 13A by the servo motor 18, the height position of the elevator 17 shown in FIGS. 1 and 2 is determined, and the saddle 16 is moved by a driving device (not shown). Thus, the position of the main shaft (C axis) 20 in the Y-axis direction is positioned at the processing position of the first processing groove 13A.

次いでテーブル１１をバイト切削に適した所定速度でＸ軸方向へ往復動させてバイト加工を行うが、テーブル１１が図５（イ）に示すベッド１０上の左端位置から図５（ロ）に示すベッド１０上の右端位置まで移動する行程を往動とする。この往動時には、バイト３０は、図５（イ）に示すように、同図において左向きに設定され、図５（イ）において左から右へ移動するワーク１３に対して加工溝１３Ａを切削加工する。なお、図６（イ）は、図５（イ）を左から見た図であり、加工溝１３Ａの形状を表すため、最初ではなく第２番目の往動時の加工開始直前の状態を示している。   Next, the table 11 is reciprocated in the X-axis direction at a predetermined speed suitable for cutting of the cutting tool to perform cutting tool processing. The table 11 is shown in FIG. 5 (B) from the left end position on the bed 10 shown in FIG. The process of moving to the right end position on the bed 10 is defined as the forward movement. At the time of this forward movement, the cutting tool 30 is set to the left as shown in FIG. 5 (a), and the machining groove 13A is cut into the workpiece 13 moving from left to right in FIG. 5 (a). To do. 6A is a view of FIG. 5A viewed from the left, and shows a state immediately before the start of machining in the second forward movement instead of the first in order to represent the shape of the machining groove 13A. ing.

ワーク１３が図５（ロ）に示すように、右端に達して往動時の切削加工を終了し、ワーク１３がバイト３０から図５（ロ）において右方へ離れると、サドル１６はクロスレール１５に沿ってＹ軸方向へ移動し、図６（ロ）に示すように、バイト３０を加工溝１３Ａの１ピッチ分だけ同図において右方へ移動させる。   As shown in FIG. 5 (b), when the work 13 reaches the right end and the cutting process during the forward movement is finished, and the work 13 is separated from the cutting tool 30 to the right in FIG. 5 (b), the saddle 16 is moved to the cross rail. 15 is moved in the Y-axis direction, and as shown in FIG. 6B, the cutting tool 30 is moved to the right in the drawing by one pitch of the machining groove 13A.

このバイト３０のＹ軸方向移動と共に、主軸（Ｃ軸）２０はサーボモータ２１により１８０°回転され、図５（ロ）及び図６（ロ）に示すように、バイト３０の向きを反転させる。このとき、バイト３０は、回転のみを行うため、Ｚ軸方向の移動はなく、このため頂点３０Ａの高さ位置の変動はなく、一定の高さ位置に保たれる。また、この頂点３０Ａは、図３及び図４に示したように、主軸（Ｃ軸）２０の軸心上に位置付けされているため、上記反転に伴う頂点３０ＡのＹ軸方向の位置ずれもなく、バイト３０の切れ刃部は１ピッチ分Ｙ軸方向へ移動した位置に正確に位置付けされる。   Along with the movement of the cutting tool 30 in the Y-axis direction, the main shaft (C-axis) 20 is rotated 180 ° by the servo motor 21 to reverse the direction of the cutting tool 30 as shown in FIGS. 5 (B) and 6 (B). At this time, since the cutting tool 30 only rotates, there is no movement in the Z-axis direction. Therefore, there is no change in the height position of the vertex 30A, and the tool 30 is maintained at a constant height position. Further, as shown in FIGS. 3 and 4, since this vertex 30A is positioned on the axis of the main axis (C axis) 20, there is no misalignment of the vertex 30A in the Y-axis direction due to the inversion. The cutting edge portion of the cutting tool 30 is accurately positioned at a position moved in the Y-axis direction by one pitch.

上記のようにバイト３０を反転させた後、テーブル１１を、図５（ロ）に示すベッド１０上の右端位置から図５（イ）に示すベッド１０上の左端位置まで移動させ、このいわゆる復動時にも加工溝１３Ａを切削加工する。   After reversing the cutting tool 30 as described above, the table 11 is moved from the right end position on the bed 10 shown in FIG. 5B to the left end position on the bed 10 shown in FIG. The machining groove 13A is also cut during movement.

上記復動時の加工が終了したならば、バイト３０を反転させて図５（イ）に示した状態に戻し、次の往動時加工を行う。以下、復動時、往動時の加工を同様に繰り返し行う。   When the machining at the time of the backward movement is completed, the cutting tool 30 is reversed to return to the state shown in FIG. 5 (a), and the machining at the next forward movement is performed. Thereafter, the processing at the time of backward movement and forward movement is repeated in the same manner.

前述した実施形態例では、バイト３０を主軸（Ｃ軸）２０の軸心上に正確に取り付けるための調芯手段として、十字継手２２を用いた例を示したが、この発明はこれに限定されるものではなく、種々の方式の調芯手段を用いることができる。   In the above-described embodiment, the example in which the cross joint 22 is used as the alignment means for accurately mounting the cutting tool 30 on the axis of the main shaft (C-axis) 20 is shown, but the present invention is limited to this. However, various types of alignment means can be used.

また、前述した実施形態例では、バイト３０を反転させることにより、往動時と復動時の両方で加工を行う例を示したが、この発明はこれに限定されるものではなく、少なくとも往動時と復動時のいずれか一方で、バイト３０の切削方向の向きを変えつつ所定の曲線を描くように切削加工を行う場合等にも適用することができる。   Further, in the above-described embodiment, an example is shown in which processing is performed both during the forward movement and during the backward movement by reversing the cutting tool 30, but the present invention is not limited to this, and at least the forward movement is performed. The present invention can also be applied to a case where cutting is performed so as to draw a predetermined curve while changing the direction of the cutting direction of the cutting tool 30 at any one of the moving time and the backward movement time.

さらにまた、前述した実施形態例では、プレーナ型工作機械を用い、バイト３０に対してワーク１３を往復動させる例を示したが、この発明はこれに限定されるものではなく、バイト３０側を往復動させるようにしてもよい。また、加工対象物は、液晶用の導光板や遮光シートなどの微細構造部品の金型に限らず、種々のワークの加工に適用することができ、さらにまた、加工形状も溝に限定されない等、種々変形実施可能である。   Furthermore, in the above-described embodiment, an example in which a planar machine tool is used to reciprocate the workpiece 13 with respect to the cutting tool 30 is shown. However, the present invention is not limited to this, and the cutting tool 30 side is arranged. You may make it reciprocate. In addition, the object to be processed is not limited to a mold of a fine structure part such as a light guide plate for liquid crystal or a light shielding sheet, but can be applied to processing various workpieces, and the processing shape is not limited to a groove. Various modifications can be made.

この発明は、プレーナ型工作機械等を用いてバイトの切削方向の向きを変えてワークを加工するバイト加工装置全般に適用できる。   The present invention can be applied to all tool processing apparatuses that process a workpiece by changing the direction of the cutting direction of the tool using a planar machine tool or the like.
