FIG. 4 is a conceptual diagram for explaining the operation of the copying apparatus 1, FIG. 4 (a) is a diagram when the model 3 is mounted, and FIG. 4 (b) is a workpiece. It is a figure when 5 arrives.

Operations and operations during machining using the copying apparatus 1 are as shown in the following (a) to (f).
(A) As shown in FIG. 4A, the worker wears the model 3 on the rotating unit 10. That is, one end of the model 3 is sandwiched and fixed to the chuck 12 a of the head stock 12. Then, the handle 14 b of the tailstock 14 is operated to press the center 14 a against the rotation center at the other end of the model 3. Thereby, the shake of the model 3 when rotating is prevented.

(C) As shown by the left-pointing arrow in FIG. 4A, the trace unit 20 operates, that is, the trace of the model 3 while the trace unit 20 moves in the direction parallel and perpendicular to the rotation axis of the model 3. Data is acquired and stored in the storage unit 50.

(D) As shown in FIG. 4B, the operator removes the model 3 from the rotating unit 10 and attaches the workpiece 5. The removal operation of the model 3 is performed in the reverse order of the operation in (a), and the workpiece 5 is mounted in the same procedure as in (a).

(E) After the worker completes the mounting of the workpiece 5 on the operation unit 102, the operator presses the processing start button of the operation unit 102.
(F) As indicated by an arrow in FIG. 4B, the cutting part moving unit 80 operates, that is, the cutting part moving unit 80 moves in a direction parallel to and perpendicular to the rotation axis of the workpiece 5. Then, the cutting unit 60 is set to the position of the trace data, and the workpiece 5 is cut into the same shape as the model 3 to produce a copy of the model 3.

(Features of the copying apparatus 1)
In the copying apparatus 1 as described above, the model 3 attached to the rotating unit 10 rotates, and the model is rotated while the outer periphery of the rotating body 22 is brought into contact with the rotating model 3 by the trace unit 20 and rotated. 3 is traced in a direction perpendicular to the rotation axis of the model 3.

Further, the trace unit moving unit 30 moves the trace unit 20 at a relatively constant speed in parallel with the rotation axis direction of the model 3.
In this way, the outer shape of the model 3 is traced, and the position of the trace unit 20 is measured by the measurement unit 40 and stored in the storage unit 50. On the other hand, when the workpiece 5 is mounted on the rotating unit 10, the cutting unit 60 is slid to the position of the trace unit 20 stored in the storage unit 50 by the cutting unit slide unit 70. Further, the cutting unit moving unit 80 moves the cutting unit slide unit 70 at the same constant speed as the trace unit moving unit 30 in parallel and relative to the rotation axis direction of the workpiece 5.

  Then, since the cutting unit 60 moves along the same locus as the trace unit 20 with respect to the model 3 in both the vertical direction and the parallel direction with respect to the rotation axis of the workpiece 5, the workpiece 5 has the same shape as the model 3.

  That is, the copying can be performed only by the position data in the direction perpendicular to the rotation axis of the model 3, and the copying apparatus 1 having a simpler configuration than the conventional copying apparatus can be obtained.

  Further, the rotating body 22 of the trace unit 20 contacts the outer diameter of the rotating model 3 while rotating according to the rotation of the rotating unit 10. That is, there is no slip or resistance with respect to the outer shape of the model 3, and the trace unit 20 can trace the outer shape of the model 3. Therefore, the shape of the model 3 can be accurately reproduced.

  Further, since the rotating body 22 has a disk shape, the tracing unit 20 can trace the outer shape of the model 3 without slipping or resistance with respect to the outer shape of the rotating model 3. Therefore, the shape of the model 3 can be accurately reproduced.

[Other Embodiments]
(1) In the above embodiment, a circular saw is used for the cutting unit 60. However, it is not necessary to be a circular saw, and other cutting tools such as a so-called router tool may be used depending on the material and processing shape of the workpiece 5. It's okay.

(3) In the said embodiment, although the trace part moving part 30 and the cutting part moving part 80 were moved at fixed speed, a moving speed does not need to be constant. For example, the moving speed of a model 3 having a simple cylindrical portion is set to be high, and the moving speed of a non-cylindrical portion is set to be low, so that the processing speed is maintained while maintaining the processing accuracy (surface roughness during processing). May be made faster.

(4) In the above embodiment, the movement speed of the trace part moving unit 30 is constant during measurement of the shape of the model 3 using the trace unit 20 and during machining using the cutting unit 60.

In this case, the trace data is processed by the control unit 100 based on the difference in the movement speed so that the trace data is processed according to the difference in the movement speed (for example, the shape of the model 3 is the same as the shape at the time of processing). Conversion).

(5) Moreover, you may make it the rotational speed of the rotary body 10 differ at the time of measurement and the time of a process. At this time, the trace data may be converted in the control unit 100 according to the difference in rotational speed so that the model 3 and the workpiece 5 have the same shape.
Further, the workpiece 5 is processed into a shape different from the shape of the model 3 by giving a difference in the rotational speed at the time of measurement and processing without processing the trace data (for example, the model 3 seems to be twisted). It is also possible to make it a simple shape.

(6) Furthermore, the control unit 100 may perform processing on the trace data so that the workpiece 5 has a shape that expands or contracts.
(7) In the above embodiment, when the trace unit 20 and the cutting unit slide unit 70 are replaced, the entire moving table 32 is replaced. However, the moving table on which the trace unit 20 and the cutting unit slide unit 70 are mounted. The 32 plate-like members 32a may be replaced.
