ものである。[Detailed Description of the Invention] The present invention relates to a method for automating an optical copying grinder,
More specifically, when grinding irregularities including curves on the outer surface using an optical tracing grinder, the position of the change point of the desired shape is manually measured on the same magnification enlarged figure of the material pasted on the screen. Position the tip of the grinding wheel or grind the material, store the coordinates of that position in the control device, and adjust the processing speed, processing order, and linear or curved interpolation between the above shape change points. The present invention relates to a method for automating an optical tracing grinder that completely automates subsequent machining by memorizing or recording the information on a tape.
従来上記のような外面に曲線を含む輪郭研削は
総形砥石車を図面に一致させてドレツシングして
研削するか、光学倣い研削盤を使つて、断面した
態様においては先端部が微小円弧状の砥石車をス

テープ化して全自動によつて研削していたのであ
る。 Conventionally, contour grinding with a curved outer surface as described above is performed by dressing a full-form grinding wheel according to the drawing, or by using an optical profiling grinder. Either move the grinding wheel according to the shape on the screen, or calculate and coordinate all the shape change points in the production drawing, tape the processing order, movement speed, linear interpolation, and curved interpolation, and grind fully automatically. That's what I was doing.
上記の総形砥石車による研削は、砥石車の摩耗
の毎にドレツシングを行うものであり、全体の凹
凸が決まつてしまうから専用の砥石車となつて汎
用性がないことと、全面が均一に摩耗しないため
に不経済で不合理な加工方法である。 Grinding using the above-mentioned full-form grinding wheel involves dressing every time the grinding wheel wears out, and since the overall unevenness is determined, the grinding wheel becomes a dedicated grinding wheel and is not versatile, and the entire surface is uniform. This is an uneconomical and unreasonable processing method to avoid wear.
第２の光学倣い研削方式は、摩耗の少いダイヤ

応できる長所はあるが、研削油を使用できず、Ｘ
軸、Ｙ軸方向の２軸を同時に手動で制御して完全
な直線や円弧を研削するには、高度の熟練を必要
としたのである。 The second optical profile grinding method has the advantage of being able to handle a wide range of contour changes by using diamond wheels with low wear, but it cannot use grinding oil and
It required a high degree of skill to manually control the two axes (axis and Y-axis) simultaneously and grind a perfect straight line or arc.
第３の所望の輪郭図形の変化点を図上計算によ
つて算出し、途中の移動条件を加えてテープ化し
完全自動で研削する研削方式は、理想的ではある
が砥石車の先端点及び２番部分の状態を無視した
加工方法であつて、数学に熟達したプログラマー
が専門に従事する必要があることから、誰でもで
きるという性質のものではないのである。 The grinding method that calculates the change point of the third desired contour figure by graphical calculation, adds intermediate movement conditions, tapes it, and grinds it completely automatically is ideal, but the tip point of the grinding wheel and the It is a processing method that ignores the state of the numbered parts, and requires the specialized work of programmers who are proficient in mathematics, so it is not something that anyone can do.
本発明で上記した従来の研削方法の欠点を克服
すべくなされたもので、専門のプログラマーでな
くても比較的容易に完全自動研削を達成した研削
方法を提供するものである。 The present invention has been made to overcome the drawbacks of the conventional grinding methods described above, and provides a grinding method that can relatively easily achieve fully automatic grinding even without a professional programmer.

として記憶装置に登録する。 First, an original image 55 corresponding to the magnification of the workpiece is pasted on the screen 43 of the projector. Fig. 4 shows the cases in which the original drawing 55 and the image of the workpiece are used, and the workpiece is projected along with the original drawing by taking a larger image of the shaded part on the processing surface of the original drawing 55. However, the process of creating the information is the same except that the workpiece is ground at the position where the contour line changes, so we will explain them together. Mazu,
The operation panel 3 is operated and the X-axis manual handle 27 and Y-axis manual handle 29 are manually rotated to position the tip of the grinding wheel 9 away from the front of the original drawing 55 on the screen. In the figure, only the tip of the grinding wheel 9 is shown in an enlarged manner, and the center of curvature of the tip radius of the grinding wheel 9 is shown as a cross. When the tip of the grinding wheel occupies the above position, the X-axis and Y-axis coordinate values of A are registered in the storage device as the coordinate origin.
次に移動速度として早送りを入力しておいて、
手動で砥石車先端アール部が、原図の左方向に大
きく直線で延びている部分の砥石車側延長線と接
する位置Ｂまで専らＹ軸方向にだけ移動し、Ｘ

手動によつて実際にＡからＢまで移動しているの
で、Ｂ点の座標値は光倣い研削盤１の備えた制御
盤４５に表示されたＸ軸、Ｙ軸座標値から、Ａ点
（原点）座標値を加減した値が登録される。 Next, input fast forward as the movement speed,
Manually move the rounded end of the grinding wheel exclusively in the Y-axis direction to position B where it touches the extended line on the grinding wheel side of the part that extends in a straight line to the left of the original drawing, and
Register the axis and Y-axis coordinate values. In this case, since the grinding wheel 9 is actually manually moved from A to B, the coordinate values of point B are the X-axis and Y-axis coordinate values displayed on the control panel 45 of the optical copy grinding machine 1. A value obtained by adding or subtracting the coordinate value of point A (origin) is registered.
次にＢ点からＣ点までの研削移動速度を入力す
る。次いで砥石車先端を手動送りで任意の経路を
移動させ、上記直線部が円弧移動に切り換るＣ点
に合わせ、Ｃ点のＸ軸、Ｙ軸座標値を登録する。 Next, input the grinding movement speed from point B to point C. Next, the tip of the grinding wheel is manually moved along an arbitrary path, and the X-axis and Y-axis coordinate values of point C are registered in alignment with point C, where the straight section switches to circular movement.
Ｂ点からＣ点までの移動は直線移動であるが、
直線移動は特に補間条件を入力しない。 The movement from point B to point C is a straight line movement, but
No particular interpolation conditions are entered for linear movement.
ところで、一般的に、制御装置の演算部は各種
の演算機能を奏し得るので、砥石車の像を直線部
の任意の複数箇所に接触せしめ、その各接触位置
の座標値に基づいて直線部の式を求めることも可
能である。 By the way, in general, the calculation unit of the control device can perform various calculation functions, so the image of the grinding wheel is brought into contact with any plurality of points on the straight line part, and the straight line part is calculated based on the coordinate values of each contact position. It is also possible to find the formula.
次にＣ点からＤ点までの移動は円弧移動である
から円弧補間信号を入力し、Ｄ点のＸ軸、Ｙ軸座
標を登録し、円弧補間の曲率半径R1（被加工物の
アールから砥石車先端アールを減した寸法）を設
計図から算出し、入力する。 Next, since the movement from point C to point D is circular movement, input the circular interpolation signal, register the X-axis and Y-axis coordinates of point D, and calculate the radius of curvature R 1 of the circular interpolation (from the radius of the workpiece). Calculate the dimension (reducing the radius of the tip of the grinding wheel) from the design drawing and enter it.
この場合、円弧上の３点以上に砥石車の像を接
触せしめ、各点における座標値に基づいて演算部
の演算処理により円の式を求めることが可能であ
る。そして、前記直線と円の接点をも演算部の演
算処理により求めることも可能である。すなわち
直線や円弧およびそれらの交点は、直線上あるい
は円弧上の複数点の座標値に基づいて、制御装置
の演算部において演算処理により求めることも可
能である。 In this case, it is possible to bring the image of the grinding wheel into contact with three or more points on the circular arc, and to obtain the equation of the circle through arithmetic processing in the arithmetic unit based on the coordinate values at each point. It is also possible to find the point of contact between the straight line and the circle through arithmetic processing in the arithmetic unit. That is, straight lines, circular arcs, and their intersections can also be determined by arithmetic processing in the calculating section of the control device based on the coordinate values of multiple points on the straight line or circular arc.
次にＤ点からＥ点への移動は直線移動にもどる
ので直線補間の信号を入力し、Ｅ点のＸ軸、Ｙ軸
座標値を登録する。 Next, since the movement from point D to point E returns to linear movement, a signal for linear interpolation is input, and the X-axis and Y-axis coordinate values of point E are registered.
次のＦ点は砥石車が被加工物から離れた位置で
あり、Ｘ軸座標値はＥ点のそれと同じく、Ｙ軸座
標値は後述するＧ点のＹ軸座標値になるべく近い
任意の位置に設定登録し、Ｅ点からＦ点間の移動
送度として早送りの指定信号を入力しておく。 The next point F is the position where the grinding wheel is away from the workpiece, the X-axis coordinate value is the same as that of point E, and the Y-axis coordinate value is an arbitrary position as close as possible to the Y-axis coordinate value of point G, which will be described later. Register the settings and input a fast forward designation signal as the movement feed rate between point E and point F.
Ｇ点、Ｈ点の座標を登録し、Ｇ点からＨ点まで
の移動は再び研削送りを入力しておく。Ｆ点から
Ｇ点までと、Ｇ点からＨ点までは何れも直線補間
で良いから特に補間指定は不要である。 Register the coordinates of point G and point H, and input the grinding feed again for movement from point G to point H. Linear interpolation is sufficient from point F to point G and from point G to point H, so there is no need to specify interpolation.
Ｈ点からＩ点までは円弧補間指令が必要であ
り、曲率半径R2（この場合は被加工物アールに砥
石車先端アールを加算した数値）と、円弧中心座
標値を入力しておき、Ｉ点の座標値も登録してお
く。 A circular interpolation command is required from point H to point I. Enter the radius of curvature R 2 (in this case, the value obtained by adding the radius of the grinding wheel tip to the radius of the workpiece) and the coordinate value of the center of the circular arc, and Also register the coordinate values of the points.
Ｉ点とＪ点との間は直線補間を指令し、Ｊ点の
座標を登録しておく。 Linear interpolation is commanded between point I and point J, and the coordinates of point J are registered.
Ｋ点は前記したＦ点と同じく、被加工物から離
れた位置であり、原点Ａに復帰する過程で被加工
物に砥石車先端が触れずに直線補間で移動できる
任意の点でよく、座標位置を登録し、早送り指令
を入力しておくことになる。 Point K, like the above-mentioned point F, is a position away from the workpiece, and may be any point that can be moved by linear interpolation without the tip of the grinding wheel touching the workpiece during the process of returning to the origin A, and the coordinates The position must be registered and a fast forward command input.
Ｋ点から原点（Ａ点）への復帰は、既に両座標
が登録されているから、復帰指令を入力すれば足
りる。 To return from point K to the origin (point A), it is sufficient to input a return command since both coordinates have already been registered.
今上記した研削プログラムを取り出して整理す
