This is preferably independent of the order and preferably includes, for each machining sequence template file 112F, a specification of a plurality of machining steps that can be executed consecutively on a machine tool and preferably also a predefined sequence of the machining steps of the predefined machining step sequence that can be executed on the machine tool.

[0084] This can be provided analogously to the processing sequence template database on the database server 210, and processing sequence templates can also be transmitted from the web server 110 to the database server 210, possibly automatically or upon request from an operating unit 230 or 260.

[0085] In addition to machining step applications and machining step sequence templates for workpiece machining jobs, further machining step applications and machining step sequence templates can also be provided, such as machining step applications and machining step sequence templates for other automated functions or operations on the machine tool, such as: The automatic assembly of workpiece pallets, the automated loading of workpiece pallets, the automatic re-sorting of workpieces on workpiece pallets, the setting of a workpiece clamping position, the changing from one clamping position to another, the automatic measurement of workpieces (e.g., before, during, and / or after machining, e.g., using measuring probes, laser measuring devices, etc.), the automatic loading of the tool magazine, the automated setup of tools on the machine tool, the automatic re-sorting of tools in the tool magazine, the automatic loading of tools on machine tools or tool magazines, e.g., for the next shift, and / or one or more automatic maintenance and repair applications or service applications on machine tools, such as filter changes or filter cleaning, or other automated machine cleaning processes or cleaning activities.

[0086] Fig. 11 Figure 1 shows a schematic exemplary representation of the data storage device 232 of an operating device 230 according to an embodiment of the present invention.

[0087] The data storage device 232 of the operating device 230 stores, for example, one (or more) GUI application(s) 232A for running the graphical user interface.

[0088] The data storage device 232 of the operating device 230 stores, by way of example, a plurality of control function applications 232B for executing control functions on the machine tool or for controlling control functions of the NC control device 240 and / or the PLC of the machine tool.

[0089] The data storage device 232 of the operating device 230 stores, for example, a plurality of process monitoring applications 232C for monitoring process parameters or sensor signals on the machine tool, e.g. based on data and / or sensor signals received from the NC, the PLC or directly via the interface 237 from sensors of the machine tool.

[0090] The data storage device 232 of the operating device 230 stores, by way of example, an editor application 232D for executing a machining step sequence editor on the graphical user interface of the user interface 233 of the operating device 230 of the machine tool 250. The editor application 232D is configured, by way of example, so that an operator can compile new predefined machining step sequences based on the machining step applications 112A provided by the web server 110, or modify machining step sequence templates already provided by the web server 110 or the database server 210. This editor functionality can preferably be made available only to operators with special authorization.

[0091] The operating unit 260 can be designed analogously to the operating unit 230, whereby the process monitoring applications 232C (remote) may remotely monitor a machine tool via the network, and whereby, for example, one or more of the control function applications 232B may optionally not be provided or may only be available to a limited extent for security reasons.

[0092] The application 232A of the graphical user interface (e.g., based on the order data 212A on the database server 210 and / or on the basis of order data 212A stored on the data storage device 232 of the operating device 230 of the machine tool 250) is configured to display a list of orders to be executed, selectable by the operator, e.g., on one of the screen areas 233A or 233B; see e.g. Fig. 12 .

[0093] Returning to Fig. 2 combined with Fig. 11The functionality of the operating device 230 of the machine tool 250 will now be described according to exemplary embodiments.

[0094] Fig. 12 The figure shows, as an example, a schematic representation of the order selection screen of the graphical user interface of the user interface 233 of the operating device 230 of the machine tool 250.

[0095] The order selection elements B1 to B5 are provided as examples, allowing the operator to select orders 1 to 5. Ideally, the selection of the corresponding orders at the operating unit 230 should only be possible by operators with sufficient authorization. This can be achieved, for example, through different user roles based on the operator's qualifications or training, such as: basic machine operator, experienced machine operator, machine loader, setup technician, machine programmer, machine maintenance technician, multi-machine operator, tool presetter, work planner, factory planner, process standardizer, etc.

[0096] Selection element B6 enables, for example, the launching of editor application 232D to execute the machining step sequence editor on the graphical user interface of user interface 233 of the operating device 230 of the machine tool 250. The editor application is configured to list the machining step applications provided on the web server and import them at the operator's request. The operator can also define the order of the imported machining step applications and save predefined machining step sequences. This editor functionality can preferably be made available only to operators with special authorization.

[0097] Preferably, the editor specifies for each processing step application which input data or input information is required, which output data or output information is provided, and / or which control functions of the machine tool are called.

[0098] In preferred embodiments, an automatic plausibility check can be performed when saving an edited machining step sequence, in which it is automatically checked for each machining step application whether the required input data is available (data availability check), either by manual input in the editor, by provision as output data of a preceding machining step application in the specified sequence, from the storage device of the operating device, the control device, from PLC registers, or by accessing database data on the database server 210 and / or the CAD-CAM system server 220.

[0099] In particular, data availability will preferably be checked not only when saving an edited or created processing step sequence, but also when linking a new order with a processing step sequence or when starting a processing step sequence linked to an order, or optionally also when (or before) executing the corresponding processing step applications.

[0100] When the operator executes a predefined processing step sequence at the operating device 230, each processing step application can only be called and executed in the order specified by the stored or imported processing step sequence, and in particular, no processing step application can be skipped.

[0101] The execution of a predefined processing step sequence assigned to a job by the operator at the operating device 230 is triggered by the operator by selecting one of the job selection elements B1 to B5, which are assigned to a respective processing job, at least insofar as his authorization allows this.

[0102] When the operator starts a specific processing step application, a new window for that application can be opened and a validity check performed (e.g., including a data availability check). Additionally, machine functions assigned to the respective processing step application can be executed.

[0103] Furthermore, in preferred embodiments, a screen display or control menu associated with the respective processing step can be automatically accessed on the other screen area, which shows a control screen of the control unit 240. This can be requested or automatically set by the data processing unit 231 of the operating unit 230 via the NC interface 235 on the control unit 240.

[0104] A first processing step application (e.g. "Accept order") can provide the operator with the order header data, e.g. based on the order data of the order file 212A assigned to the order to be executed by import from the database server 210.

[0105] By confirming the processing step (e.g., "Accept order"), the order can be set to the "Execution" status. This can also be automatically reported to a production monitoring system via network 200.

[0106] Another (optional) processing step application can involve loading tools or checking tool requirements, see Fig. 13 .

[0107] Fig. 13 The diagram schematically shows an example of a tool inspection screen of the graphical user interface of the user interface 233 of the operating device 230 of the machine tool 250.

[0108] The required tools are specified here (e.g., based on a tool list file 212C assigned to the job to be executed). Furthermore, based on the data available at the operating unit, the tools present on the machine tool can be displayed, along with any tools that are still missing or need to be loaded.

[0109] By activating the selection element B7 "Load tools", the operator can proceed to tool loading in order to load any missing tools or enter the corresponding tool data (or either import it from tool data 212B if previously scanned, or import it from a tool presetting device connected to the network 200 after scanning the tool), see e.g. Fig. 14 .

[0110] Fig. 14Figure 2 schematically shows an example of a tool loading screen of the graphical user interface of the user interface 233 of the operating device 230 of the machine tool 250.

[0111] By selecting option B8 "Manual input", the operator can scan the missing tools before loading them at the tool station and then enter the data manually, or import it from a tool presetting device connected to the network 200 by selecting option B9 "Import from tool station".

[0112] Another (optional) processing step application can involve loading or programming the NC code, see Fig. 15 .

[0113] Fig. 15 Figure 2 schematically shows an example of an NC code loading screen of the graphical user interface of the user interface 233 of the operating device 230 of the machine tool 250.

[0114] Examples of NC files assigned to the order are shown (e.g., based on the order data of the assigned order file 212A). These can be exported to the control unit 240 by selecting option B10 "Load NC file into NC" (if necessary, after importing the corresponding file(s) from the CAD / CAM system server 220). By selecting option B10 "Edit NC file", the operator can edit (or create) a loaded file in the display window shown above, provided the operator has the necessary authorization.

[0115] After tool loading, clamping center setup if necessary, and NC code provision in order and type according to the specified machining step sequence (and possibly after further specified steps), workpiece machining can be carried out, possibly in conjunction with specified process monitoring, subsequent process documentation, and possibly optional quality inspection, until in a final machining step the operator can confirm the order as completed or executed.

[0116] According to one or more of the above embodiments, the operation or control of a machine tool can be extended and improved, in particular with regard to the operability or the automation or semi-automated support of machining steps of a workpiece machining order, possibly also by partially untrained or inexperienced operators.

[0117] Examples and embodiments of the present invention, as well as their advantages, have been described in detail above with reference to the accompanying figures. It should be emphasized again that the present invention is in no way limited or restricted to the embodiments and features described above.
