Description
【０００１】[0001]
本考案は、物品識別用媒体としてのバーコード用の溝を、物品上に能率的に形 成するためのバーコード用溝切削工具に関する。 The present invention relates to a bar code groove cutting tool for efficiently forming a bar code groove as an article identification medium on an article.
【０００２】[0002]
一般に商品の包装等に用いられるバーコードは、明色のラベル上に、幅の異な る複数種類の暗色の棒状印刷部を、その幅方向に多数本互いに平行に形成してな り、このバーコードの表面に上方からレーザ等のスキャンビーム（以下「光」と いう。）を照射し、その反射光が明暗に従って発生する光のパルスを受光素子で 電気信号に変換する。 In general, bar codes used for product packaging etc. consist of a number of dark-colored bar-shaped printed parts of different widths formed on a light-colored label in parallel with each other in the width direction. A scan beam (hereinafter referred to as "light") such as a laser is applied to the surface of the code from above, and the light pulse generated by the reflected light according to the light and dark is converted into an electric signal by the light receiving element.
【０００３】[0003]
しかし、この従来のバーコードを自動精密加工ライン等において物品の識別に 用いると、ラベルの厚さにより加工精度が低下しやすく、また物品に直接印刷す る方法では、熱処理や化学処理を施すと棒状印刷部が褪色して誤読の虞が生ずる という問題点があった。 However, if this conventional bar code is used to identify an article in an automatic precision processing line, etc., the processing accuracy tends to decrease due to the thickness of the label, and in the method of printing directly on the article, heat treatment or chemical treatment is required. There is a problem in that the stick-shaped printing section may be discolored and misread may occur.
【０００４】 そこで本考案の考案者は、従来の棒状印刷部に代わる記録部として、幅の異な る複数種類の溝を、物品１の表面に多数形成してなるバーコードＢを考案し、既 に試作している。図８は、その試作品のバーコードＢであり、細幅溝２ａ，太幅 溝２ｂを、所定の組み合わせで、その並び方向に対し斜めに多数本形成したもの である。このバーコードＢは、ＬＥＤアレイなどの発光素子Ｃにより斜め上方よ り光Ｓを照射し、溝２ａ，２ｂ内に生じた影を、ＣＣＤなどの受光素子Ｄにより 、信号として検出する。溝２ａ，２ｂの配列をそれらの並び方向に対して斜めと した目的は、溝２ａ，２ｂ内に照射した光の反射に起因する誤読の虞を解消する ことにある。Therefore, the inventor of the present invention devised a bar code B in which a plurality of kinds of grooves having different widths are formed on the surface of the article 1 as a recording portion to replace the conventional bar-shaped printing portion, It is being prototyped. FIG. 8 shows a bar code B of the prototype, in which a large number of narrow grooves 2a and wide grooves 2b are formed in a predetermined combination at an angle with respect to the arrangement direction. The bar code B emits light S from a light emitting element C such as an LED array from an obliquely upper side, and a shadow formed in the grooves 2a and 2b is detected as a signal by a light receiving element D such as a CCD. The purpose of making the arrangement of the grooves 2a and 2b oblique with respect to the arrangement direction thereof is to eliminate the risk of erroneous reading due to the reflection of the light irradiated in the grooves 2a and 2b.
【０００５】 この試作品のバーコードＢの製造は、厚さの異なる２種類のフライスカッタを 用いた切削加工により行っていた。しかし、このように溝の幅の種類に応じた厚 さの違う複数種類のカッタは、溝２ａ，２ｂの配列が並び方向に対して斜めであ るため、同一の駆動軸に連装することはできない。このため、この試作品では、 ２つの駆動軸を用い、第１駆動軸に薄いカッタを装着し、第２駆動軸に厚いカッ タを装着し、まず第１駆動軸を用いて細幅溝２Ｃのみを形成し、次に第２駆動軸 を用いて太幅溝２Ｂを形成するという２工程を要していた。The bar code B of this prototype was manufactured by cutting using two types of milling cutters having different thicknesses. However, in such a plurality of types of cutters having different thicknesses depending on the type of the groove width, since the arrangement of the grooves 2a and 2b is oblique with respect to the arrangement direction, they cannot be connected to the same drive shaft. Can not. For this reason, in this prototype, two drive shafts were used, a thin cutter was attached to the first drive shaft, a thick cutter was attached to the second drive shaft, and the narrow groove 2C was first attached using the first drive shaft. This requires two steps of forming only the groove and then forming the wide groove 2B using the second drive shaft.
【０００６】 しかし、このように溝の幅の種類に応じた複数種類のカッタおよび複数の駆動 軸を用いるのはバーコード製造装置が複雑となるばかりでなく、工程数の増加が 避けられず、生産性が向上しがたいという問題点があった。However, using a plurality of types of cutters and a plurality of drive shafts according to the type of groove width in this way not only complicates the bar code manufacturing apparatus, but also increases the number of processes, which is inevitable. There was a problem that productivity was hard to improve.
【０００７】 そこで本考案の考案者は、図９（ａ）に示すように先端に小径切削部２２、及 びその基部側に大径切削部２３を有する特殊なエンドミル２１を考案した。この エンドミル２１は、物品１に対する切込み深さを大小に変更して使用し、細幅溝 ２７を形成するときには物品１に浅く切り込み（図９（ｂ））、また太幅溝２８ を形成するときには深く切り込む（図９（ｃ））。次にその切り込んだ状態から 横方向に送りを加えて、溝２７，２８とするものである（図９（ｄ））。このよ うに、形成すべき溝の幅に応じた複数種類の径の切削部を有するエンドミルを用 いれば、複数種類の幅の溝を単一のエンドミル２１で形成できる。また、小径、 中径、大径の３種類の切削部を備えるエンドミルを用いれば、３種類の幅の溝の 形成も可能である。Therefore, the inventor of the present invention has devised a special end mill 21 having a small diameter cutting portion 22 at the tip and a large diameter cutting portion 23 at the base side thereof, as shown in FIG. 9A. This end mill 21 is used by changing the depth of cut for the article 1 to be large or small. When forming the narrow groove 27, the end mill 21 is shallowly cut (FIG. 9B), and when forming the wide groove 28. Make a deep cut (Fig. 9 (c)). Next, the groove 27, 28 is formed by laterally feeding from the cut state (FIG. 9 (d)). As described above, by using the end mill having the cutting portions of plural kinds of diameters corresponding to the width of the groove to be formed, the groove of plural kinds of width can be formed by the single end mill 21. Further, by using an end mill having three kinds of cutting parts of small diameter, medium diameter and large diameter, it is possible to form grooves of three kinds of widths.
【０００８】 しかし、微細なバーコード（この試作品では細幅溝２７の幅は０．５mm程度で ある）を形成するには極めて細いエンドミル２１を必要とするため、切削工程に おいては特に小径切削部２２が折損しやすいという欠点があった。However, in order to form a fine bar code (the width of the narrow groove 27 is about 0.5 mm in this prototype), an extremely thin end mill 21 is required. There is a drawback that the small-diameter cutting portion 22 is easily broken.
【０００９】 そこで本考案は、これらの問題点を解決すべく、幅の異なる複数種類の溝から なるバーコードを形成するにあたり、バーコードの製造工程を簡略化して生産性 を向上すると共に、切削工具の耐久性の高いバーコード用溝切削工具を提供する ことを目的とする。Therefore, in order to solve these problems, the present invention simplifies the manufacturing process of a bar code to improve productivity when forming a bar code composed of a plurality of types of grooves having different widths. It is an object of the present invention to provide a groove cutting tool for bar codes with high tool durability.
【００１０】[0010]
本考案は上記の問題点を解決すべくなされたものであり、請求項１の考案は、 バーコード用の細幅の溝を形成すべき大径切削部に隣接して、バーコード用の太 幅の溝を形成すべき小径切削部を一体的に同一回転軸上に設けてなるバーコード 用溝切削工具である。 The present invention has been made to solve the above-mentioned problems, and the invention of claim 1 adjoins a large-diameter cutting portion in which a narrow groove for a bar code is to be formed and has a thick bar code. This is a bar code groove cutting tool in which a small-diameter cutting portion for forming a groove having a width is integrally provided on the same rotary shaft.
【００１１】 また請求項２の考案は、円盤体の外周縁を切削頂部とし、該切削頂部に対し円 盤体両側面側の切削面が前記切削頂部を挟んで互いに６０度以下の角度を成すこ とを特徴とするバーコード用溝切削工具である。Further, in the invention of claim 2, the outer peripheral edge of the disk body is used as a cutting apex, and the cutting surfaces on both sides of the disk body form an angle of 60 degrees or less with respect to the cutting apex with the cutting apex interposed therebetween. It is a groove cutting tool for barcodes, which is characterized by a small size.
【００１２】 また請求項３の考案は、砥石からなる円盤体の外周縁を切削頂部とし、該切削 頂部に対し円盤体両側面側の切削面が前記切削頂部を挟んで互いに６０度以下の 角度を成すことを特徴とするバーコード用溝切削工具である。[0012] According to a third aspect of the present invention, the outer peripheral edge of the disk body made of a grindstone is used as a cutting apex, and the cutting surfaces on both side surfaces of the disk body with respect to the cutting apex have an angle of 60 degrees or less with respect to the cutting apex. It is a groove cutting tool for barcodes which is characterized by
【００１３】[0013]
本考案の切削工具を回転しながら、物品に向け外周端のみを浅く挿入して切削 すれば、物品には外周端の厚さに応じた細幅溝が形成される。また、物品に向け 切削工具を深く挿入し、回転軸側の部分をも用いて切削すれば、物品には回転軸 側部分の厚さに応じた太幅溝が形成される。 When the cutting tool of the present invention is rotated and only the outer peripheral edge is shallowly inserted toward the article for cutting, a narrow groove corresponding to the thickness of the outer peripheral edge is formed in the article. Further, if a cutting tool is deeply inserted toward the article and cutting is also performed using the rotary shaft side portion, a wide groove corresponding to the thickness of the rotary shaft side portion is formed in the article.
【００１４】 このように本考案は、切削工具の挿入深さを変化させることにより、切削工具 を交換することなく、単一の切削工具で幅の異なる複数種類の溝が形成でき、も って工程数を減少して生産性が向上できる。As described above, according to the present invention, by changing the insertion depth of the cutting tool, it is possible to form plural kinds of grooves having different widths with a single cutting tool without exchanging the cutting tool. Productivity can be improved by reducing the number of steps.
【００１５】 また切削工具は円盤上の所謂円鋸刃であるから、エンドミルに比して欠損・破 損の虞が少なく、これを極めて小型に製造した場合にも耐久性が高い。Further, since the cutting tool is a so-called circular saw blade on a disk, there is less risk of chipping and damage as compared with an end mill, and the durability is high even when manufactured in an extremely small size.
【００１６】 また請求項２及び３の考案において、両切削斜面のなす角度を６０度以下とし た目的は、これらの考案の切削工具により形成したバーコードの誤読の虞を解消 するにある。これを以下に図７に従って説明する。In the inventions of claims 2 and 3, the purpose of making the angle formed by both cutting slopes 60 degrees or less is to eliminate the risk of erroneous reading of the bar code formed by the cutting tool of these inventions. This will be described below with reference to FIG. 7.
【００１７】 図７は物品３６上に断面Ｖ字形の溝３９を形成したものを示す切欠側面図であ る。５０は物品３６の表面、３９Ａは左側壁、３９Ｂは右側壁であり、両側壁３ ９Ａ，３９Ｂのなす角度をθとする。いま、この溝３９に対して上方から光Ｓ１ を垂直方向に照射すると、光Ｓ１はＰ１において左側壁３９Ａに対しθ／２の角 度で入射する結果、垂直に対しθの角度で反射する。FIG. 7 is a cutaway side view showing a groove 39 having a V-shaped cross section formed on the article 36. Reference numeral 50 is the surface of the article 36, 39A is the left side wall, and 39B is the right side wall, and the angle formed by both side walls 39A, 39B is θ. When the light S1 is vertically applied to the groove 39 from above, the light S1 is incident on the left side wall 39A at P1 at an angle of θ / 2, and is reflected at an angle of θ with respect to the vertical.
【００１８】 次に、光Ｓ１は右側壁３９Ｂに対し３／２θの角度で入射する（Ｐ２）。その 結果光Ｓ１は右側壁３９Ｂに対し３／２θの角度、即ち垂直に対し４／２θの角 度で反射する。その後、光Ｓ１は左側壁３９Ａ、右側壁３９Ｂを交互に反射しな がら進行する。Next, the light S1 is incident on the right side wall 39B at an angle of 3 / 2θ (P2). As a result, the light S1 is reflected at an angle of 3 / 2θ with respect to the right side wall 39B, that is, at an angle of 4 / 2θ with respect to the vertical direction. After that, the light S1 proceeds while alternately reflecting on the left side wall 39A and the right side wall 39B.
【００１９】 ここで、光Ｓの進行方向は、側壁３９Ａもしくは３９Ｂに対する反射角が９０ 度を超えた時点から上向きに転じ、やがては溝３９から上方へ脱出するが、本考 案の考案者の詳細な研究により、この上方への反射光に起因する受光素子Ｄの誤 読の虞を解消するには、光Ｓ１を溝３９内で少なくとも３回反射させて減衰させ れば良いことが判明した。Here, the traveling direction of the light S turns upward when the reflection angle with respect to the side wall 39A or 39B exceeds 90 degrees, and eventually escapes upward from the groove 39. Detailed studies have revealed that in order to eliminate the possibility of misreading of the light receiving element D due to the upward reflected light, the light S1 may be reflected at least three times in the groove 39 and attenuated. ..
【００２０】 従って、光Ｓ１の２番目の反射点であるＰ２における反射角３／２θを９０度 以下とする、すなわち角θを６０度以下とすれば、光Ｓ１が溝３９内を少なくと も３回以上反射し、もって反射光に起因する誤読の虞を防止できる。Therefore, if the reflection angle 3 / 2θ at P2, which is the second reflection point of the light S1, is 90 degrees or less, that is, if the angle θ is 60 degrees or less, the light S1 is at least in the groove 39. It is possible to prevent the risk of misreading due to reflected light by reflecting the light three times or more.
【００２１】[0021]
以下に、図面を参照して本考案の実施例につき説明する。 Embodiments of the present invention will be described below with reference to the drawings.
【００２２】 図１は、請求項１の考案の実施例である第１実施例の切削工具を示す。図１に おいてＡは、配線基板のような板状の物品１に太幅および細幅の二種類の溝５， ６を形成するための切削工具であり、大径切削部２の左右両側面に、小径切削部 ３を一体的に接着する。これら大径切削部２、および小径切削部３としては、金 属等の溝切りや切断に一般的に用いられるメタルソーをそれぞれ用いる。FIG. 1 shows a cutting tool of a first embodiment which is an embodiment of the invention of claim 1. In FIG. 1, A is a cutting tool for forming two kinds of grooves 5 and 6 of a wide width and a narrow width in a plate-like article 1 such as a wiring board. The small diameter cutting portion 3 is integrally bonded to the surface. As the large-diameter cutting portion 2 and the small-diameter cutting portion 3, metal saws generally used for grooving and cutting metal or the like are used.
【００２３】 一方、この切削工具Ａを用いる工作機械Ｅは、切削工具Ａを装着すべき駆動軸 ４、該駆動軸４を回転駆動する駆動装置Ｆ、切削工具Ａの物品１に対する切り込 み深さを２段階に調節すべき切込深度調節装置Ｇ、および物品１に図中矢印Ｈ１ 方向の送り運動を加える送り装置Ｈを有する。On the other hand, a machine tool E using this cutting tool A has a drive shaft 4 on which the cutting tool A is to be mounted, a drive device F for rotationally driving the drive shaft 4, and a cutting depth of the cutting tool A with respect to the article 1. It has a depth-of-cut adjusting device G for adjusting the depth in two steps, and a feeding device H for applying a feeding movement to the article 1 in the direction of arrow H1 in the figure.
【００２４】 しかして、切削工具Ａを工作機械Ｅの駆動軸４に取り付け、回転させて切削に 供する。Then, the cutting tool A is attached to the drive shaft 4 of the machine tool E and rotated to be used for cutting.
【００２５】 まず、物品１を定位置に配置し、図２（ａ）のように、物品Ａに向け大径切削 部２のみを浅く切込んで切削する。このとき、物品Ａには大径切削部２の厚さに 応じた細幅溝５が形成される。First, the article 1 is placed at a fixed position, and as shown in FIG. 2A, only the large-diameter cutting portion 2 is shallowly cut and cut toward the article A. At this time, the narrow groove 5 corresponding to the thickness of the large-diameter cut portion 2 is formed in the article A.
【００２６】 次に、図２（ｂ）に示すように物品１に所定の送りを加え、物品１に向け小径 切削部３までを深く切込んで切削すれば、物品１には大径切削部２および小径切 削部３の厚さの合計に応じた太幅溝６が形成される。Next, as shown in FIG. 2 (b), a predetermined feed is applied to the article 1 to deeply cut the small-diameter cutting portion 3 toward the article 1 to cut the large-diameter cutting portion of the article 1. The wide groove 6 is formed according to the total thickness of 2 and the small-diameter cut portion 3.
【００２７】 このような切削工程を一直線上に、所定の組み合わせで行うことにより、物品 １上には図３に示すようなバーコードＪが形成される。溝５，７は細幅溝であり 、溝６，８は太幅溝である。またこれら溝５〜８の穿設間隔も大小２種類に設定 し、小間隔９および大間隔１０の２種類とする。The bar code J as shown in FIG. 3 is formed on the article 1 by performing such a cutting process on a straight line in a predetermined combination. The grooves 5 and 7 are narrow width grooves, and the grooves 6 and 8 are wide width grooves. In addition, the intervals between the grooves 5 to 8 are set to two types, large and small, and there are two types of small intervals 9 and large intervals 10.
【００２８】 このようにしてバーコードＪを形成した物品１は、図３に示すように、自動精 密加工ライン等において物品の認識および判別に用いる。この場合は、バーコー ドＪの表面にＬＥＤアレイなどの発光素子Ｃにより光を照射すると、物品１の平 面部９，１０に反射した光がＣＣＤなどの受光素子Ｄに到達する一方、溝例えば ５〜８に照射した光は反射せず、暗部として検出される。そして受光素子Ｄは、 例えば細幅溝５，７および小間隔９を「０」とし、太幅溝６，８および大間隔１ ０を「１」として認識する。The article 1 on which the barcode J is formed in this manner is used for recognition and discrimination of the article in an automatic precision processing line or the like, as shown in FIG. In this case, when the surface of the bar code J is irradiated with light by the light emitting element C such as an LED array, the light reflected by the flat surface portions 9 and 10 of the article 1 reaches the light receiving element D such as CCD, while the groove, for example, 5 The light radiated to 8 is not reflected and is detected as a dark part. Then, the light receiving element D recognizes the narrow grooves 5, 7 and the small interval 9 as "0", and recognizes the wide grooves 6, 8 and the large interval 10 as "1".
【００２９】 このように、本実施例の切削工具Ａによれば、切削工具Ａの切込深さを変化さ せることにより、切削工具Ａを交換することなく、幅の異なる複数種類の溝５〜 ８が形成でき、もって工程数が減少して生産性が向上できる。As described above, according to the cutting tool A of the present embodiment, by changing the cutting depth of the cutting tool A, it is possible to replace a plurality of types of grooves 5 having different widths without replacing the cutting tool A. 8 can be formed, so that the number of steps can be reduced and the productivity can be improved.
【００３０】 また、切削工具Ａは円盤状の所謂円鋸刃であるから、エンドミルに比して欠損 ・破損の虞が少なく、これを極めて小型に製造した場合にも高い耐久性を確保で きる。Further, since the cutting tool A is a disc-shaped so-called circular saw blade, there is less risk of chipping / damage as compared with an end mill, and high durability can be ensured even when it is manufactured in an extremely small size. ..
【００３１】 なお、上述の第１実施例では、切削工具Ａの切削部の径は大径（大径切削部２ ）および小径（小径切削部３）の二種類として構成したが、これを三種類以上の 多種類に構成すると共に、切込深度調節装置Ｇによる深度調節を三段階に行う等 のように構成すれば、より多様な幅の溝を工作しうる。In the above-described first embodiment, the diameter of the cutting portion of the cutting tool A is configured as two kinds, that is, a large diameter (large diameter cutting portion 2) and a small diameter (small diameter cutting portion 3). If the groove depth is adjusted to three or more types and the depth adjustment by the cutting depth adjusting device G is performed in three steps, it is possible to machine grooves of various widths.
【００３２】 また、上記実施例においては、大径切削部２に小径切削部３を接着する構成と したが、これを接着でなく一体成型で製造してもよい。また、上記実施例におい ては大径切削部２の一側面に小径切削部３を形成する構成としたが、小径切削部 ３は大径切削部２の両側面に形成してもよい。Further, in the above embodiment, the small-diameter cutting portion 3 is bonded to the large-diameter cutting portion 2, but the small-diameter cutting portion 3 may be integrally molded instead of being bonded. Further, in the above embodiment, the small diameter cutting portion 3 is formed on one side surface of the large diameter cutting portion 2, but the small diameter cutting portion 3 may be formed on both side surfaces of the large diameter cutting portion 2.
【００３３】 また、本実施例で用いた工作機械Ｅは、工作物に対する切削工具Ａの切り込み 深さを２段階に調節すべき切込深度調節装置Ｇ、および工作物に送り運動を加え る送り装置Ｈを有するものを用いたが、切削工具Ａを昇降させずに工作物を昇降 させて切り込み深さを調節する構成としてもよい。あるいは、切削工具Ａの昇降 を１段階とする一方、工作物を昇降させる機構を設け、細幅溝を形成するときに は切削工具Ａを下降し、太幅溝を形成するときには切削工具Ａを下降すると共に 工作物を上昇する構成とすれば、駆動軸４付近の構成が簡易になるという利点が ある。Further, the machine tool E used in the present embodiment has a cutting depth adjusting device G for adjusting the cutting depth of the cutting tool A to the work piece in two steps, and a feed for applying a feed motion to the work piece. Although the device having the device H is used, the cutting depth may be adjusted by moving the workpiece up and down without moving the cutting tool A up and down. Alternatively, while raising and lowering the cutting tool A in one step, a mechanism for raising and lowering the workpiece is provided, and the cutting tool A is lowered when forming a narrow groove and the cutting tool A is formed when forming a wide groove. If the structure is such that the work is raised while the work is lowered, there is an advantage that the structure near the drive shaft 4 becomes simple.
【００３４】 次に、請求項２の考案の実施例である第２実施例について説明する。図４（ａ ）において、Ｃは第２実施例の切削工具であり、円盤体３２の外周縁を切削頂部 ３３とし、切削頂部３３の両側面側に切削斜面３４，３５を設けてなる。切削斜 面３４，３５は切削頂部３３を挟んで互いに６０度以下の角度を成す。Next, a second embodiment which is an embodiment of the invention of claim 2 will be described. In FIG. 4 (a), C is the cutting tool of the second embodiment, which has the outer peripheral edge of the disk body 32 as the cutting top portion 33, and the cutting slopes 34 and 35 are provided on both side surfaces of the cutting top portion 33. The cutting slopes 34 and 35 form an angle of 60 degrees or less with each other with the cutting top 33 interposed therebetween.
【００３５】 しかして、第２実施例の切削工具Ｃを用いてバーコードを形成する工程を説明 する。切削工具Ｃは第１実施例の場合と同様の工作機械Ｅ（図示省略）に取り付 ける。Now, a process of forming a barcode using the cutting tool C of the second embodiment will be described. The cutting tool C can be attached to the machine tool E (not shown) similar to that of the first embodiment.
【００３６】 まず、物品３６を定位置に配置し、図４（ｂ）に示すように切削頂部３３付近 のみを浅く切り込んで切削すれば、物品３６には切削頂部３３付近の厚さに応じ た細幅のＶ字型の溝３８が形成される。First, the article 36 is placed at a fixed position, and only the vicinity of the cutting top 33 is shallowly cut as shown in FIG. A narrow V-shaped groove 38 is formed.
【００３７】 次に、図４（ｃ）に示すように物品３６に所定の送りを加えたのち、物品３６ に向け切削斜面３４，３５までを深く切り込んで切削すれば、物品３６には切削 斜面３４，３５の厚さに応じた太幅のＶ字溝３９が形成される。このような切削 工程を一直線上に、所定の組み合わせで行うことにより、物品３６には図６（ａ ）に示すようなバーコード３２が形成される。Next, as shown in FIG. 4C, after a predetermined feed is applied to the article 36, if the cutting slopes 34, 35 are deeply cut toward the article 36 and cut, the article 36 has a cutting slope. A wide V-shaped groove 39 corresponding to the thickness of 34 and 35 is formed. By performing such a cutting process on a straight line in a predetermined combination, the bar code 32 as shown in FIG. 6A is formed on the article 36.

In FIG. 5 (a), D is the cutting tool of the third embodiment, in which the outer peripheral edge of the disk body 42 made of a grindstone is the cutting top 43, and the cutting slopes 44, 45 are provided on both side surfaces of the cutting top 43. Become. The cutting slopes 44 and 45 form an angle of 60 degrees or less with each other with the cutting top 43 interposed therebetween.
【００４０】 しかして、第３実施例の切削工具Ｄを用いてバーコードを形成する工程を説明 する。切削工具Ｄは、第１実施例の場合と同様の工作機械Ｅ（図示省略）に取り 付ける。Now, a process of forming a barcode using the cutting tool D of the third embodiment will be described. The cutting tool D is attached to the machine tool E (not shown) similar to that of the first embodiment.
【００４１】 まず、物品４６を定位置に配置し、図６（ｂ）に示すように切削頂部４３付近 のみを浅く切り込んで切削すれば、物品４６には切削頂部４３付近の厚さに応じ た細幅のＶ字溝４８が形成される。First, the article 46 is placed at a fixed position, and only the vicinity of the cutting top portion 43 is shallowly cut as shown in FIG. 6B, and the article 46 is cut according to the thickness near the cutting top portion 43. A narrow V-shaped groove 48 is formed.
【００４２】 次に、図６（ｃ）に示すように物品４６に所定の送りを加えたのち、物品４６ に向け切削斜面４４，４５までを深く切り込んで切削すれば、物品４６には切削 斜面４４，４５の厚さに応じた太幅のＶ字溝４９が形成される。このような切削 工程を一直線上に、所定の組み合わせで行うことにより、物品４６には図６（ａ ）に示すものと同様のバーコード３２が形成される。Next, as shown in FIG. 6C, after a predetermined feed is applied to the article 46, if the cutting slopes 44, 45 are deeply cut toward the article 46 and cut, the article 46 has a cutting slope. A V-shaped groove 49 having a large width corresponding to the thickness of 44 and 45 is formed. By performing such a cutting process on a straight line in a predetermined combination, the bar code 32 similar to that shown in FIG. 6A is formed on the article 46.
【００４３】 この第３実施例の切削工具Ｄは、上述の第２実施例の切削工具Ｃと同様に切削 斜面４４，４５のなす角度を６０度以下としたので、形成されるＶ字溝４８，４ ９に照射した光がＶ字溝４８，４９内で少なくとも３回反射し、その結果Ｖ字溝 ４８，４９内からの反射光に起因する誤読の虞が解消できる。また本実施例の切 削工具Ｄは、切削頂部４３及び切削斜面４４，４５を砥石により形成したので、 第２実施例の切削工具Ｃに比して硬質の物品、例えば焼き入れ鋼やガラス、セラ ミック等の切削にも適する。The cutting tool D of the third embodiment has the V-shaped groove 48 formed because the angle formed by the cutting slopes 44 and 45 is set to 60 degrees or less, like the cutting tool C of the second embodiment. , 49 is reflected at least three times in the V-shaped grooves 48, 49, and as a result, the risk of erroneous reading due to the reflected light from the V-shaped grooves 48, 49 can be eliminated. Further, the cutting tool D of the present embodiment has the cutting top portion 43 and the cutting slopes 44, 45 formed by a grindstone, so that it is harder than the cutting tool C of the second embodiment, for example, hardened steel or glass, Also suitable for cutting ceramics.
【００４４】 尚、第２実施例及び第３実施例の切削工具Ｃ，Ｄによれば、上述した理由から 、形成したＶ字溝からの反射光に起因する誤読の虞を防止できるため、各Ｖ字溝 の方向は、図６（ａ）のごとくそれらの配列方向に対して斜めとせず、図６（ｂ ）のごとく各Ｖ字溝の配列方向に対して直交方向に配置しうる。この場合には、 配列方向を斜めとした場合に比して物品５１上のバーコード５２の占有面積が小 さくて済むという利点がある。For the reasons described above, the cutting tools C and D of the second and third embodiments can prevent misreading due to the reflected light from the formed V-shaped groove. The direction of the V-shaped grooves can be arranged orthogonal to the direction of arrangement of the respective V-shaped grooves as shown in FIG. 6B, instead of being inclined with respect to the direction of arrangement thereof as shown in FIG. 6A. In this case, there is an advantage that the occupied area of the bar code 52 on the article 51 can be smaller than that in the case where the arrangement direction is oblique.
