関するものである。The present invention relates to a shape processing method and apparatus, and for example, to a shape processing method and apparatus for a workpiece that requires processing a rond lens of an optical component, a connector end face, etc. into a convex curved shape.

精度かつ高品位の凸状曲面に加工する必要がある。Currently, the end faces of indenters and pivot shafts commonly used in various industrial applications are formed into convex spherical curved surfaces. In particular, the end faces of special lenses and connectors as optical components need to be processed into convex curved surfaces with high precision and high quality.

１９を押しつけて加工するものである。Conventionally, there has been a shape processing device as shown in FIG. 4 for obtaining such a convex curved surface. In this shape processing device, an arcuate groove 13 having a constant curvature in cross section is carved approximately at the center of the upper surface of the polishing plate 1). The polishing plate 1) is machined by pressing the surface 19 of a workpiece 17 gripped by a rotating body 15 against the polishing plate 1).

９は球面形に加工される。Here, the rotary body 15 is connected to a rotational drive source (not shown) by a belt 21, and the workpiece surface 19 of the workpiece 17 rotates by applying a rotational force in the direction of arrow a. In addition, the rotating body 15 is rotated in the longitudinal direction (already indicated by the arrow) of the arcuate groove 13 relative to the polishing plate 1).
make a reciprocating motion. In this way, the workpiece 17 is driven laterally and rotationally. Furthermore, processing is continued by supplying a processing agent (not shown) between the polishing plate 1) and the workpiece 17. As a result, the workpiece surface 1 of the workpiece 17
9 is processed into a spherical shape.

心とが一致させである。In addition, there was a device for machining the spherical surface of a rod as a workpiece, as shown in FIG. This is basically the same as shown in FIG. In the figure, the surface 3 of the surface plate 31
3 is formed into a predetermined curved shape, and the center axis intersection of the workpiece 35 (for example, a ferrule of an optical connector having a through hole for passing an optical fiber) coincides with the spherical center of the surface 33 of the surface plate 31. It's a shame.

れるものであった。The surface plate 31 is rotated around the center of the spherical surface of the surface 33 so that the rotation axis coincides with the rotation axis 34, and the tip surface of the workpiece 35 is rotated along the surface 33 of the surface plate 31 using the holder 37. oscillate (in the direction shown by arrow d). Polishing was carried out by performing a so-called "grinding" motion and by supplying machining fluid containing diamond fine particles between it and the surface 33 of the surface plate 31 from a nozzle-shaped member 39. As a result, the end face of the workpiece 35 was machined into a spherical shape.

なるという問題点があった。However, in such a conventional spherical surface processing apparatus, it is necessary to manufacture the polishing dish 1), which is a master spherical surface polishing dish, and the surface plate 31 using separate dedicated equipment. Further, as the spherical surface is used, the processed spherical surface becomes different from the initial shape due to wear over time. Even if such a different processed spherical surface was to be corrected, it was necessary to once remove the polishing plate 1) or the surface plate 31 from the processing device and perform the processing again using a separate dedicated correction device. Therefore, removal work and a separate dedicated repair device were required, and the repair also required highly skilled techniques. Therefore, in the spherical surface machining method, there are problems in that the apparatus is large-scale, and it takes a lot of effort and time.

なという不都合があった。In addition, especially in the conventional example shown in FIG.
When attaching a plurality of workpieces 35 such as optical connectors to the workpiece 7, it is necessary to assemble the workpieces 35 (ferrules) so that the end surfaces of all the workpieces 35 (ferrules) are in uniform contact with the surface 33 of the surface plate 31. Ta. This was done manually, resulting in extremely low work efficiency. Furthermore, even when processing only one piece, there is the inconvenience that at least two wooden dummies must be used.
更に、保持具３７の揺動運動形態が前述したように複雑
であるために、その運動の高速化を図ることは極めて困
難であり、研磨皿となる定盤３１には、錫等の軟質金属
を用いることから、加工圧力１周速が限定されていた。Furthermore, since the oscillating motion of the holder 37 is complicated as described above, it is extremely difficult to increase the speed of its motion, and the surface plate 31, which serves as a polishing plate, is made of a soft metal such as tin. Because of this, the machining pressure and per-peripheral speed were limited.
そのため、加工の高能率化が図れず、加工に要する時間
が極めて多大となるという問題点が指摘されていた。Therefore, it has been pointed out that there is a problem that high efficiency of processing cannot be achieved and the time required for processing is extremely large.

If such a movement pattern is adopted, the workpiece 45 hits the workpiece 45 uniformly, so that there is no need to modify the shape of the grindstone tool 43.

等は、第１図のものと同じであるので省略している。A second embodiment is shown in FIGS. 2(A) and 2(B). Here, the difference from the first embodiment shown in FIG. 1 is that a ring-shaped base metal 61 with both ends open and having a constant thickness is used;
A grindstone tool 63 is formed on the inner surface thereof. That is, the predetermined angle θ in the first embodiment described above is 90°.
is equivalent to . In this example as well, the workpiece rotation axis 53 for the workpiece 45 is perpendicular to the forming surface of the grindstone tool 63. However, spindle 47. Machining fluid supply nozzle 49
etc. are the same as those in FIG. 1, so they are omitted.

て往復運動させるものである。In this second embodiment as well, the motion form during processing is substantially the same as in the first embodiment. Further, the method of bringing the workpiece 45 into contact with the grindstone tool 63 may be either a forced cutting method or a pressurizing method. Here, too, when processing the workpiece 45, the grindstone tool 63 is rotated around the rotation axis 51, and the workpiece 45 is rotated around the rotation axis 51.
The grindstone tool 63 is rotated with respect to the grindstone tool 63 and reciprocated along the surface of the grindstone tool 63.

具６３の半径Ｒの値が比較的大きい場合に適する。In addition, the spherical shape of the end face processing of the workpiece 45 is uniquely determined by the second embodiment in which the angle is set to θ-90°. Therefore, in order to obtain an arbitrary desired spherical shape, it is necessary to restrict the value of the radius R of the grindstone tool 63, which limits the configuration of the processing device. Therefore, it is suitable when the radius R of the grindstone tool 63 is relatively large.
