Abstract

The invention relates to a method of reducing vibrations, occurring during a machining operation, of a machine element (7,8) and/or of a workpiece (5) in a machine tool, production machine and/or in a machine (1) designed as a robot, wherein an additional mass (9a, 9b, 9c) is attached to the machine element (7,8) and/or to the workpiece (5) in an automated manner, wherein the mass of the additional mass (9a, 9b, 9c) is adapted to the machining operation. Furthermore, the invention relates to a machine (1) in this respect. The invention enables vibrations, occurring during a machining operation, of a machine element (7,8) of a machine (1) and/or of a workpiece (5) to be reduced.

Claims

1-11. -11. (canceled)

12. A method for reducing vibrations of a machine element and/or workpiece during a machining process, comprising the steps of:

selecting a compensation mass having a mass suited to a machining process; and

attaching the compensation mass in an automated fashion upon the machine element and/or workpiece.

13. The method of claim 12, wherein the machine element and/or workpiece are intended for use in a member selected from the group consisting of machine tool, production machine, and robot.

14. The method of claim 12, wherein the compensation mass is attached upon the machine element and/or to the workpiece in close proximity to the machining process.

15. The method of claim 12, wherein the compensation mass is attached in symmetry upon the machine element and/or the workpiece.

16. The method of claim 13, wherein the selecting step includes the step adapting a regulating parameter of the member for the machining process to the mass of the compensation mass.

17. The method of claim 12, wherein the attaching step is realized by a member selected from the group consisting of gripper, clamping device, and magnetic holder, with the member being part of the machine element and/or the workpiece.

18. The method of claim 12, wherein the attaching step is realized by means of an automatic exchange device which permits a selection of a plurality of additional compensation masses with different masses.

19. The method of claim 18, wherein the selecting step includes the step of matching a compensation mass of increased mass as an actuating force required for the machining process increases and/or a feed of the workpiece and/or a tool increases.

20. The method of claim 12, further comprising the step of automatically interrupting the machining process in the presence of vibrations before carrying out the selecting and attaching steps, and automatically continuing the machining process after the selecting and attaching steps.

21. The method of claim 12, wherein the attaching step is implemented during the machining process.

22. The method of claim 12, wherein the selecting step includes the step of selecting the compensation mass as a function of a dominant frequency of the vibrations.

23. A machine, comprising:

a machine element;

a compensation mass detachably secured in an automated fashion to the machine element, said compensation mass having a mass adapted to the machining process.

24. The machine of claim 23, embodied as a machine tool, production machine and/or robot.

25. The machine of claim 23, further comprising a member selected from the group consisting of gripper, clamping device, and magnetic holder, with the member being part of the machine element and/or the workpiece.
