Abstract

A method for operating a numerically controlled production machine includes defining a permissible value range determined by the design and construction of the production machine in which, in a normal operation during production of a workpiece, values representing a mechanical or electrical load described by acceleration and/or jolting of at least one component of the numerically controlled production machine are variable, and activating, for producing the workpiece, with a control signal a conservation operation for reducing the mechanical or electrical loads, wherein in the conservation operation the values of acceleration and/or jolting of the at least one component are variable within a part value range that is limited in comparison to the permissible value range.

First claim

What is claimed is:

1. A method for operating a numerically controlled production machine, comprising:
defining a permissible value range determined by the design and construction of the production machine in which, in a normal operation during production of a workpiece, values representing a mechanical or electrical load described by acceleration and/or jolting of at least one component of the numerically controlled production machine are variable, and
activating, for the production of the workpiece, with a control signal a conservation operation for reducing the mechanical or electrical loads, wherein In the conservation operation the values of acceleration and/or jolting of the at least one component are variable within a part value range that is limited in comparison to the permissible value range,
wherein the production of the workpiece comprises at least one first production step, in which the at least one component acts on the workpiece and, in the conservation operation, the values of acceleration and/or jolting of the at least one component are variable within the permissible value range, and at least one second production step, in which the at least one component does not act on the workpiece and, in the conservation operation, the values of acceleration and/or jolting of the at least one component are variable only within the limited part value range.

2. The method of claim 1 , wherein the at least one component moves at least along an axis and variables describing movement along at least the axis comprise an axis acceleration.

3. The method of claim 1 , wherein the control signal is specified by a manual input at an input/output unit of the numerically controlled production machine.

4. The method of claim 1 , wherein the control signal is triggered by a state of the at least one component of the production machine.

5. The method of claim 1 , wherein the control signal is triggered when a limit temperature of at least one component of the production machine is exceeded.

6. The method of claim 1 , wherein the control signal is triggered by remote control.

7. The method of claim 1 , wherein the control signal is triggered in a time-controlled manner.

8. The method of claim 1 , wherein the production machine is embedded in a computer network and the control signal is specified by a control computer that is connected to the computer network.

9. The method of claim 1 , wherein the production machine is embodied as a machine tool.

10. The method of claim 1 , wherein the production machine is embodied as a manufacturing robot.

11. A numerical controller for a production machine, said numerical controller being configured to perform the method of claim 1 .

12. The method of claim 1 , further comprising:
detecting the control signal;
operating the numerically controlled production machine in the normal mode when the control signal is not detected; and
operating the numerically controlled production machine in the conservation operation, when the control signal is detected, in a first implementation of the conservation operation, wherein the values of the acceleration and/or the jolting of the at least one component are variable within the permissible value range in the at least one first production step and the values of acceleration and/or jolting of the at least one component are variable only within the limited part value range in the at least one second production step.

13. The method of claim 12 , further comprising operating the numerically controlled production machine in a second implementation of the conservation operation, when the control signal is detected, wherein the values of the acceleration and/or the jolting of the at least one component are variable only within the limited part value range in the at least one first production step and the at least one second production step.

14. The method of claim 1 , further comprising:
providing the permissible value range at a time of commissioning of the numerically controlled production machine; and
specifying and/or changing the limited part value range by an operator of the numerically controlled production machine.
