しが生ずる欠点があった。Conventionally, in order to create a rotation square hyperboloid surface and its spherical surface, a workpiece W is attached to the end face of a spindle 2 and a spindle device 1 for rotating it at high speed is movable in the axis direction of the spindle, as shown in FIG. At the same time, the tool 3 is fixed on a slide table 4 that can move in a direction orthogonal to the ↓ axis, and the slide table 4 and the spindle device L are controlled to feed by numerical control while the workpiece W is rotating at high speed. There is a device that creates a hyperboloid of rotation by making the cutting edge draw a predetermined hyperbola.6 In such conventional devices, the rotational speed of the workpiece at the cutting point of the cutting tool is the cutting speed, so the cutting speed at the center of rotation of the workpiece is Since the speed is close to zero, cutting cannot be performed, which has the disadvantage of leaving uncut parts.

本発明による回転二乗双曲面の創成原理について説明す
る。The principle of creating a rotation square hyperboloid according to the present invention will be explained.
一般に回転二乗双曲面をxyz座標系で表わせば回転対

が創成される。この球面の一部がMM’を含むとき双曲
面のMM’が切削される。Generally, when a rotation square hyperboloid is expressed in an xyz coordinate system, the axis of rotational symmetry is the X axis. This curved surface is an envelope surface of an inscribed sphere centered on a point on the X-axis. Therefore, as shown in Figure 2, the tool side passes through the OC and is tilted by θ with the X axis as the rotation axis.
If the rotary tool radius PQC'' is rotated and the workpiece side is rotated once around the X axis, part of the inscribed sphere OC Q Q/ s s /
is created. When part of this spherical surface includes MM', the hyperboloid MM' is cut.
OCの位置を頂点Tに接する球の中心位置までX軸線に
沿って移動しく第3図参照)同時にOcPの長さを変化
させれば回転二乗双曲面MTIφ′が創成される。If the position of OC is moved along the X-axis to the center position of the sphere in contact with vertex T (see FIG. 3) and the length of OcP is changed at the same time, a rotational square hyperboloid MTIφ' is created.
円 (x+a−)−X)2−1−y2=R2が接する

乗双曲面は創成される。In order for the circle (x+a-)-X)2-1-y2=R2 to be tangent, it satisfies x ``''-a, y = O, so Q at this time is made to coincide with point T, so again this ( 2) If 2 and X are controlled using the relationship shown in equation 2, a rotation square hyperboloid can be created.

The numerical control device 4 connects a large number of points determined by the obtained 2 and
Let it be done at 0. In this case, the fish school data of 2 and X are programmed in advance and stored in the storage device 41 built into the numerical control device 40. Simultaneous 2 output from the numerical control device 40
Among the pulse trains of the axes, the pulse train of the A-axis is driven by the servo motor S.
Ma is applied to move the tool headstock 23 in the direction of the tool rotation axis U to control the distance Z from the intersection OC to the cutting edge rotation plane, and the pulse train for the other B-axis is generated by the servo motor SMt).
, move the work bed 31 in the direction of the work rotation axis V, and calculate the distance X from the intersection Oc to the work creation surface.
control. In this way, when a set of 2 and
i: Since it is machined, each time the workpiece W is rotated once, another set of 2 and X is given, and by sequentially shifting the machining point in the two-axis direction, a rotation square hyperboloid can be created.

In this case, the motor for driving the work is also a servo motor, and the numerical control device 40 is programmed with a set of fish school data Cα, Z, X) including the work rotation angle α, and this data allows simultaneous It is sufficient to perform pulse distribution on three axes and apply the distributed pulses to each servo motor.

速度は低下せず切削残しは生じない。According to the present invention, the tool is rotated around an axis that makes an angle with the workpiece axis, the tool and the workpiece are controlled to move relative to each other in the direction of the tool rotation axis and the workpiece rotation axis, and the workpiece is rotated. Since the tool moves in a hyperbolic manner on the workpiece creation surface to create a rotation square hyperboloid surface, the cutting speed will not decrease and no uncut material will be left even if the cutting point of the tool is at the center of rotation of the workpiece. .
