Abstract
Machine (10) with an NC control unit (11) and at least one motor (12) which can be triggered by said control unit (11) and which forms an oscillatory system with its bearing and/or parts of the machine (10). The control unit (10) injects control variables (S1) into the motor (12) which trigger a desired motion of the motor (12). When necessary, the control unit (11) additionally injects predetermined signal variables (S2) into the motor (12) which trigger desired mechanical oscillations of the oscillatory system. The signal variables (S2) are predetermined in such a way that the mechanical oscillations are audible and/or tangible.

Machine tool or production machine (10) with an NC control unit (11) and at least one motor (12) which can be triggered by said control unit (11), is used as a direct drive and forms with its bearing (4, 4′) and/or parts of the machine (10) an oscillatory system, with the control unit (11) providing the motor (12) with control variables (S1) which trigger a productive controlled motion of the motor (12), characterized in that
- the control unit (11) provides the motor (12) with predetermined signal variables (S2) which cause the desired mechanical oscillations of the oscillatory system, with the signal variables (S2) being predetermined in such a way that the mechanical oscillations are audible and/or tangible.
Method for generating audible and/or tangible signals in a machine tool or production machine (10) which comprises an NC control unit (11) and a motor which can be controlled by said control unit (11) and which forms an oscillatory system with its bearing (4, 4′) and/or parts of the machine (10) comprising the steps of:
- generating signal variables (S2) by the control unit (11) which are to trigger desired mechanical oscillations of the oscillatory system;
- providing the signal variables (S2) to the motor (12) in order to induce mechanical oscillations in the oscillatory system via the motor (12), with the mechanical oscillations being audible and/or tangible in the vicinity of the machine (10).
