Abstract

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for switching between different operating modes on a processing machine. The operating modes are different from one another in respect of operator intervention requirements of an operator of the processing machine, One of the methods includes switching from a first operating mode to a second operating mode, looking up stored operating settings specific to the second operating mode and related to one or more potential operator interventions, changing operation of the processing machine in accordance of the stored operating settings specific to the second operating mode, and providing feedback to the operator of the machine, indicating whether a switch to the second operating mode is complete or whether at least one of the potential operator interventions is required.

First claim

What is claimed is:

1. A method of switching between different workpiece processing operating modes on a processing machine, the operating modes being different from one another in respect of operator intervention requirements of an operator of the processing machine, the method comprising:
for each of the operating modes, storing respective operation settings that are specific for potential operator interventions requested by the machine operator;
switching from an operator-attended first workpiece processing operating mode (a first operating mode) to a non-operator-attended second workpiece processing operating mode (a second operating mode);
changing, by a machine control system, operation of the processing machine in at least one of a processing sequence, a process safety, quality of a processing result, a processing speed, and a degree of automation in accordance of the stored operating settings specific to the second operating mode;
providing feedback from the machine control system to the operator of the processing machine, indicating whether a switch to the second operating mode is complete or whether at least one of the potential operator interventions is required;
determining, by the machine control system, that the switch to the second operating mode is complete;
anticipating, by the machine control system, a future second operating mode fault condition in the processing machine; and
in response to anticipating a future second operating mode fault condition, providing, by the machine control system, an indication to the operator, indicating an early operator intervention to be performed to enable an extension of operation of the processing machine in the second operating mode.

2. The method of claim 1 , further comprising:
determining respective operating settings relating to the potential operator interventions for the different operating modes of the processing machine; and
storing the determined operating settings for the different operating modes.

3. The method of claim 2 , wherein the determined operating settings for the different operating modes differ from each other in respect of at least one of a processing sequence, a process safety, quality of a processing result, a processing speed, or a degree of automation.

4. The method of claim 2 , wherein determining respective operating settings comprises determining at least one of a higher process safety, a lower processing speed, or a higher degree of automation for an operating mode with a lower operator intervention requirement than an operating mode with a higher operator intervention requirement.

5. The method of claim 1 , wherein the processing machine includes at least one of a machine for laser cutting, a machine for laser tube cutting, a machine for punching, a machine for punch laser processing, or a machine for bending workpieces.

6. The method of claim 1 , further comprising:
determining whether a next operator intervention is required;
in response to determining that the next operator intervention is required, determining when the next operator intervention is required; and
in response to determining that the next operator intervention is required at a specific time point, notifying the operator that the next operator intervention is required at the specific time point.

7. The method of claim 1 , further comprising receiving an operation from the operator to initiate the switch from the first operating mode to the second operating mode.

8. The method of claim 1 , wherein switching from a first operating mode to a second operating mode comprises switching from the first operating mode to the second operating mode in a time-controlled manner or by remote access.

9. The method of claim 1 , wherein the stored operating settings specific to the second operation mode include details in respect of whether and what information about the second operation mode is transferred by remote access.

10. A workpiece processing machine comprising:
a memory configured to store respective operating settings relating to potential operator interventions for different workpiece processing operating modes of the workpiece processing machine, the operating modes being different from one another in respect of the operator intervention requirements of an operator of the workpiece processing machine;
a control system configured to change an operation of the processing machine in at least one of a processing sequence, a process safety, quality of a processing result, a processing speed, and a degree of automation in accordance with operating settings stored in the memory, in response to switching from an operator-attended first operating mode (a first operating mode) of the processing machine to a non-operator-attended second operating mode (a second operating mode) of the processing machine; and
an operator feedback device operable by the control system
to provide a feedback to an operator of the machine as to whether switching from the first operating mode to the second operating mode is complete, and
to provide an indication to the operator, indicating whether an early operator interventions is required to extend operation of the processing machine in the second operating mode, wherein the indication is being provided in response to anticipating a future second operating mode fault condition.

11. The workpiece processing machine of claim 10 , wherein the processing machine includes at least one of a machine for laser cutting, a machine for laser tube cutting, a machine for punching, a machine for punch laser processing, or a machine for bending workpieces.

12. The workpiece processing machine of claim 10 , wherein the operating settings for the different operating modes differ from each other in respect of at least one of a processing sequence, a process safety, quality of a processing result, a processing speed, or a degree of automation.

13. The workpiece processing machine of claim 10 , wherein the control system is configured to:
determine that switching from the first operating mode to the second operating mode is complete;
determine whether a next operator intervention is required;
in response to determining that the next operator intervention is required, determine when the next operator intervention is required at a specific time point; and
in response to determining that the next operator intervention is required at a specific time point, notify the operator that the next operator intervention is required at the specific time point.

14. The workpiece processing machine of claim 10 , wherein the control system is configured to switch from the first operating mode to the second operating mode in a time-controlled manner or by remote access.

15. The workpiece processing machine of claim 10 , wherein the second operating condition includes details in respect of whether and what information about the second operation mode is transmitted by remote access.

16. A non-transitory computer readable storage medium storing instructions executable by a data processing apparatus and configured to, upon such execution, cause a workpiece processing machine to:
switch from a first operating mode to a second operating mode;
look up stored operating settings specific to the second operating mode and related to one or more potential operator interventions;
change operation of the processing machine in at least one of a processing sequence, a process safety, quality of a processing result, a processing speed, and a degree of automation in accordance of the stored operating settings specific to the second operating mode;
provide feedbac
