Therefore, it is related with improvement of a device which carries out creation processing. (PRIOR ART) Generally, the piston, the workpiece, for example, the engine for vehicles, in which section shape is not formed in the perfect circle, is formed in the elliptical form in consideration of the heat modification at the time of engine performance. As the device which manufactures products, such as a piston of such non-perfect circle shape, By preparing the template corresponding to the product configuration made profitably like, and giving sending to working tools, such as a byte, according to the template, it was made to carry out creation processing, a workpiece is learned, and, generally the processing device of the formula is known well conventionally. On the other hand, it is indicated by JP,60-228003,A as a moving system of the tool stand which makes a working tool support, for example, By arranging a piezoelectric element appropriately on the undersurface of a tool stand, vibration of the above-mentioned tool stand by the external force by a workpiece acting on a working tool is lost with the characteristic of the above-mentioned piezoelectric element, and the thing which enabled it to move a tool stand smoothly by this is proposed. When (the problem which an invention tends to solve), and time manufactured the product in which the above-mentioned former learns and standards differ in the processing device of a formula, the template had to be prepared for every product and there was a problem that this template creation took time and effort. In the present invention, a place which learns, is made in view of such a problem by a method, and is made into the object A lecture a suitable means to make a piezoelectric element used for the above-mentioned example of a gazette participate in operation of a working tool which carries out creation processing of the workpiece. Therefore, the template which is learned and is used for processing of a method can be made into needlessness, troublesomeness of work which it becomes unnecessary to prepare a template for every product when this manufactures non-perfect circle-shaped products, such as a piston of for example, an engine for vehicles, even if a standard of a product changes, and is called template creation -- it is going to cancel -- it is in things. (Problem which an invention tends to solve) In order to achieve the above-mentioned object, the solving means of the present invention is aimed at the device which carries out creation processing by moving a working tool to the radial direction of the above-mentioned workpiece, rotating a workpiece, when manufacturing the product of the non-perfect circle shape like Above.

Next, the operation of the creation processing device concerning the above-mentioned example is explained. First, after setting workpiece W to principal axis 4, principal axis 4 is rotated by the drive of the 1st motor 6. Subsequently, tool buck 17 is dropped to a processing position by the drive of the 3rd motor 16, and the processing starting position of workpiece W under above-mentioned rotation is made to carry out the correspondence position of the byte 24. Can come, simultaneously send movable table 10 by the drive of the 2nd motor 13, it is made to move, and creation processing of workpiece W is started. During this processing, the rotation angle of the above-mentioned principal axis 4 is detected by rotation angle detection means 9, and the pulse signal at this time is inputted into control means 25. On the other hand, byte's 24 amount of ° sending is detected by position detecting means 14, and the pulse signal at this time is inputted into control means 25.

When the voltage which these both piezoelectric elements ig and is carried out elastic displacement, for example, was impressed to upper piezoelectric element 18 by this is larger than a lower thing, While creation arm 20 is made to rotate the circumference of pivot 22.22 in the specified quantity by the direction of 1st [ The ] figure counterclockwise rotation, when the voltage conversely impressed to lower piezoelectric element 18 is larger than an upper thing, it is made, as for creation arm 2o, to rotate the circumference of pivot 22.22 in the specified quantity by 1st [ The ] figure clockwise direction. Thus, by carrying out rotation displacement of the creation arm 20 in the specified quantity according to the product configuration made profitably like, byte 24 is moved to the radial direction of workpiece W, and creation processing of the workpiece W is carried out. Thus, rotation angle detection means 9 by which this example detected the rotation angle of principal axis 4, Carry out elastic displacement of both the piezoelectric elements 18.18 by voltage control by control means 25, creation arm 20 is made by this to rotate based on each pulse signal with position detecting means 14 which detected byte's 24 amount of sending, and byte 24 is moved to the radial direction of workpiece W. Therefore, the template needed when non-perfect circle-shaped products, such as a piston of the engine for vehicles, were learned and were manufactured from a method, for example can be made into needlessness, Even if the standard of a product changes by this, it becomes unnecessary to prepare a template for every product, and can cancel the troublesomeness of work called template creation. (EFFECT OF THE INVENTION) As explained above, in the present invention, by a rotation angle detection means's detecting a rotation angle of a principal axis which carries out support rotation of the workpiece, and displacing a piezoelectric element in the specified quantity according to this detected principal-axis rotation angle, a working tool is made to move to a radial direction of a workpiece, and creation processing of the workpiece is carried out. Therefore, non-perfect circle-shaped products, such as a piston of an engine for vehicles, can be manufactured, for example, without using a template, and troublesome work called template creation can be eliminated.
