いる。FIG. 2 is a schematic diagram of a processing apparatus according to an embodiment of the present invention. The workpiece 1 is supported by a magnetic bearing 7 via a check 5. Furthermore, it is rotated in the A direction by a motor installed within the main body 15. The magnetic bearing 7 is controlled by a magnetic bearing controller 16,
The rotating shaft 8a can be moved by approximately ±500 μm within a plane orthogonal to the shaft. The orthogonal slide tables 10 and 12 have a mechanism for mounting the tool rest 14 and the tool 2 in directions D and E within a plane including the rotation axis 8 of the workpiece 2, and 11,
Reference numeral 13 denotes a handle for moving each orthogonal two axes. Furthermore, a table feed screw 15 is provided to move the entire orthogonal slide tables 10, 12 largely in the F direction.

物１の仕上り寸法が、初期の目的を達することとなる。The operation of the processing apparatus constructed as described above will be explained below. First, when machining into a predetermined shape, move the orthogonal slide tables 10, 12 to the table moving handles 11, 1 until the tool edge is very close to the machining start point and the tool edge does not contact the workpiece 1.
Move by 3. Next, a predetermined rotation is applied to the workpiece 1, and the tool 2 is further moved in the direction D to make a cut. From this state, the feed screw 15 is rotated to feed the entire table in the B direction to start machining. Then, the magnetic bearing controller 17 gradually changes the rotational axis of the workpiece 1 from 8 to the C direction based on previously input operation data that takes into account wear of the tool 2 and elastic deformation of the workpiece 1 due to machining. It moves to 9. Through this operation, the finished dimensions of the workpiece 1 at the end of machining will reach the initial objective.
