Description

Technical Field

[0001] The present invention relates to a data system for generating and transmitting operation data to a numerically controlled machine tool, a data interface device for the data system for generating and transmitting operation data to a numerically controlled machine tool, a manufacturing system and a method for controlling a numerically controlled machine tool. Background Art

[0002] In the field of automated product manufacturing, numerically controlled machine tools (NC machine tools or CNC machine tools) are generally used, which are arranged in a machine park in order to perform the machining operations required to produce the product on the workpiece on which they are based.

[0003] The machine tool or its control receives data about the machining operations to be performed by the machine tool from various sources. In the process, the machine tool usually receives detailed information about the machining sequence, that is, the sequence of the individual machining steps and the NC programs required for these steps.

[0004] The information about the machining sequence is usually provided by the production control system (MES system for manufacturing execution system), while the NC program is provided by the CAM system (computer-aided manufacturing system).

[0005] Providing the information or data required to perform a machining job is difficult, especially when using multiple different machine tools (which is completely the case in a machine park) and different CAM or production control systems, because these systems usually require different data transmission protocols for data transmission and even different files and / or data formats for the data to be transmitted.

[0006] As a result, the integration of new machines or alternative CAM and / or production control systems in particular becomes more difficult, since they need to be manually adjusted beforehand, which is both time-consuming and cost-intensive and also has a negative impact on the flexibility of manufacturing in the machine park. This becomes even more difficult, especially in the case of a diverse machine park consisting of old, foreign and new machines. Summary of the invention

[0007] It is therefore an object of the present invention to provide a more efficient option for providing work for numerically controlled machine tools in a machine tool park.

[0008] To achieve this object, a data system according to claim 1, a data interface device according to claim 13, a manufacturing system according to claim 14 and a method for controlling a numerically controlled machine tool according to claim 15 are implemented.

[0009] The other dependent claims relate to preferred embodiments of the method or of the machine tool, which can be implemented individually or in combination.

[0010] According to a first aspect of the present invention, a data system for generating and transmitting operation data to at least one numerical control machine tool is implemented, the data system comprising: a data interface device, the data interface device further comprising an interface module for data transmission and a data processing module for data processing and data generation; a CAM system, the CAM system being configured to generate and provide an NC program for workpiece processing on a numerical control machine tool, and being connected to the data interface device through its interface module for data transmission; and a production control system, the production control system being configured to generate and provide manufacturing data for a single product to be manufactured and / or a plurality of products to be manufactured, and being connected to the data interface device through its interface module for data transmission. The data interface device is configured to generate an operation data set readable by a numerical control machine tool through the data processing module based on an NC program data set received from the CAM system and a manufacturing data set received from the production control system, and to transmit the operation data set to the numerical control machine tool coupled thereto, in particular to the control device of the machine tool, through the interface module.

[0011] Therefore, both the data system and the data interface device have a common interface which bundles together the data that was previously mostly transferred manually to the machine tool (via USB stick etc.) and collects and transfers this data to the machine tool as a job data set.

[0012] In this way, workflows in mass production are increasingly automated, saving time and costs. In addition, errors or data losses when transferring data to the machine can be reduced.

[0013] As a further advantage, the flexibility of the machine park can also be increased. Thus, for example, new machine tools can be integrated without much effort and can be supplied directly with data from the CAM and production control system via the data interface device.

[0014] A job data set is a set of specific job data, a manufacturing data set is a set of specific manufacturing data, and an NC program data set is a set of specific NC programs or multiple specific NC subprograms.

[0015] An NC program is a program that can be executed by the controller of a numerically controlled machine tool in order to control the actuators of the machine tool in the manner specified in the NC program.

[0016] The data or file format of the NC program and the programming language may differ depending on the machine tool.

[0017] The manufacturing data is related to the manufacturing sequence of the product to be manufactured and can contain the sequence of machines to be operated, such as machining first on machine 1, then additive manufacturing on machine 2, etc. Likewise, the manufacturing data can also contain the chronological sequence of machining steps on a single machine, such as first milling, then drilling, then grinding, etc.

[0018] Furthermore, the manufacturing data may also contain other data. The following may be mentioned, but are not limited to: product name or title, customer information of the recipient of the product, priorities, technical drawings, load and duty manuals, etc. All information contained in the manufacturing data may also be transferred to the job data. Preferably, it is predetermined which parts of the manufacturing data will be used to generate the job data.

[0019] Job data are understood to be data usable by the receiving machine tool, which comprise a combination of one or more NC programs or NC subprograms executable by the machine tool and data relating to the manufacturing sequence of the product to be manufactured.

[0020] Thus, the order data set may contain information on the chronological sequence of the processing steps, wherein an NC program usable by the machine tool or a plurality of NC subroutines executed in the chronological sequence of the processing steps are stored in the order data set for each processing step.

[0021] In particular, the NC (sub)program stored in the job data is in the form of a file and data format readable or usable by the machine tool or an executable programming language. The NC program stored in the job data may be different from the NC program provided by the CAM system.

[0022] A CAM system is to be understood here as a general term for a pure CAM system, a CAM / CAD system or a pure CAD system (CAD: Computer-Aided Design).

[0023] The data interface device is preferably configured to provide the order data set to be transmitted in a file format suitable for the receiving machine tool or its control device and / or in a suitable data format and / or in a suitable programming language.

[0024] To this end, the data processing module can be configured to generate a job data set directly from the manufacturing data set and the NC program data set in a suitable file format and / or a suitable data format and / or a suitable programming language, so that the job data set can be read by the machine tool or its control device.

[0025] Optionally, the data system may include a conversion module, which is configured to convert the job data set generated by the data processing module into a job data set readable by the machine tool, and before transmitting the converted job data set through the interface module, modify the file format of the generated job data set to a suitable file format and / or modify the data format of the generated job data set to a suitable data format and / or modify the programming language of the job data set to a suitable programming language.

[0026] When generating and / or converting a job data set, the data interface device is preferably not limited to a file format, a data format or a programming language, but can select in an appropriate manner from a plurality of predefined file formats and / or a plurality of predefined data formats and / or a plurality of predefined programming languages.

[0027] Therefore, the data interface device is preferably configured to communicate with multiple machine tools, especially different machine tools, through an interface module, and generate job data corresponding to a file format, data format or available programming language readable by each machine tool (or its control device) and / or adjust or convert the file, data format or programming language of the generated job data set.

[0028] Preferably, the interface module is configured to select a suitable communication protocol from a plurality of communication protocols for data transmission with the machine tool or its control device and / or CAM system and / or production control system. This enables communication with various different systems or control devices using communication protocols different from the universal standard.

[0029] The communication protocol in data transmission regulates the serialization of the data to be transmitted, so that these data are transmitted in a sequential form from the sender to the receiver, wherein the receiver in question must of course be able to use the corresponding communication protocol. The data transmitted by means of the communication protocol are deserialized after reception and are finally made available to the receiver.

[0030] The Transmission Control Protocol (TCP), preferably with binary encoding, or the Simple Object Access Protocol (SOAP) may be cited as non-limiting examples of a plurality of communication protocols.

[0031] In a preferred embodiment, the data interface device is at least partially, in particular completely, implemented as part of a first server structure, which is coupled to the CAM system and the production control system via an Internet or an Intranet connection for data transmission, in particular the data interface device is cloud-based.

[0032] Therefore, the interface module can be provided locally, while the data processing module for processing data is arranged on a server with generally more powerful computing power. However, alternatively, the interface module can also be arranged on a server for complete implementation.

[0033] This enables central provision of data interface devices, which can then be used in the factory hall or even across locations.

[0034] In a preferred embodiment, the production control system is at least partially implemented as part of a second server structure, which is coupled to the data interface device via an Internet or intranet connection for data transmission, in particular the production control system is cloud-based.

[0035] In a preferred embodiment, the CAM system is at least partially implemented as part of a third server structure, which is coupled to the data interface device via an Internet or Intranet connection for data transmission, in particular the CAM system is cloud-based.

[0036] Therefore, production control system and / or CAM system can be arranged at least partly on the server that provides centrally, and this server can realize more powerful in computing power usually.In addition, production control system and / or CAM system also can be used across factory hall even across location therefore.

[0037] Preferably, the CAM system and the production control system each have a user interface, in particular a local user interface, via which an operator can enter data into the CAM or production control system on the server.

[0038] In a preferred embodiment, the interface module comprises a standardized API interface, in particular an open API interface, for data transmission with a CAM system and a production control system.

[0039] Thus, the CAM system and the production control system can be coupled to the data interface device in a particularly simple manner, so that in particular CAM systems and production control systems of different manufacturers can be coupled quickly.

[0040] In a preferred embodiment, the data interface device is configured to generate a job data set based on a plurality of production data sets received from a production control system.

[0041] Thus, for example, a plurality of processing orders can be prioritized. For example, if production data sets with different priorities are transmitted, the data processing module can compare the priorities and accordingly select the production data set that is first converted into a job data set together with the associated NC program data set.

[0042] In a preferred embodiment, a manufacturing data set generated by a production control system and receivable by a data interface device includes one or more sub-data sets, each sub-data set containing information related to a manufacturing sequence of at least one product to be manufactured, or information related to a processing sequence on a machine tool, or information related to a priority of at least one product to be manufactured.

[0043] In a preferred embodiment, the interface module of the data interface device is configured to perform data transmission with a plurality of production control systems, each of which is configured differently.

[0044] Thus, multiple production control systems may be used, for example from different locations or even from different production control systems themselves.

[0045] In a preferred embodiment, the data processing module of the data interface device is configured to read and process the production data set in at least two different data and / or file formats and / or programming languages.

[0046] In a preferred embodiment, the data system comprises N additional production control systems, where N≥1, which are coupled to the data interface device via their interface modules for data transmission.

[0047] In a preferred embodiment, the data system comprises M further CAM systems, where M≥1, which are coupled to the data interface device via their interface modules for data transmission.

[0048] The functionality of the data system can be expanded by multiple production control systems and CAM systems. Thus, for example, in the case of a CAM system, a non-existent functionality can be retrofitted by merging another CAM system into the data system.

[0049] In a preferred embodiment, the interface module is configured to perform data transmission with a plurality of CNC machine tools, each CNC machine tool being configured differently and the CNC machine tools being distinguished from each other by differently configured control devices.

[0050] The data interface device is configured to, also in a similar manner as described above, select a file format suitable for a receiving machine tool (or its control device) among the multiple machine tools from a plurality of predefined file formats and / or select a suitable data format from a plurality of predefined data formats and / or select a suitable programming language from a plurality of predefined programming languages, and provide a job data set to be transmitted to the relevant machine tool in the selected file format and / or the selected data format and / or the selected programming language.

[0052] Optionally, for this purpose, the data system may also include a conversion module, which is configured to convert the job data set already generated by the data processing module into a job data set readable by the machine tool (or its control device), and to modify the data format of the generated job data set to a selected data format and / or modify the file format of the generated job data set to a selected file format and / or convert the programming language of the generated job data set into a selected programming language before transmitting the converted job data set through the interface module.

[0053] In a preferred embodiment, the data interface device is configured to receive a workpiece machining process data set generated by a CNC machine tool through an interface module, and forward the workpiece machining process data set to a CAM system and / or a production control system through the interface module.

[0054] In this way, the data interface device can simultaneously be used as part of a process monitoring system, wherein, for example, process parameters are fed back to a production control system so that, for example, quality control can be performed therein.

[0055] In particular, the data interface device is preferably configured to convert the process data set received from the machine tool by means of the conversion module before forwarding, into a data format readable and / or a file format readable by a CAM system and / or a production control system.

[0075] Both the CAM system 20 and the production control system 30 comprise, for example, a CPU 21, 31 as a data processing system and a storage unit 22, 32. In addition, both systems 20, 30 have a user interface 23, 33, via which user inputs can be detected and via which the user can input or modify, for example, NC program data sets or manufacturing data sets.

[0076] The data interface device 10 is configured to generate a job data set that can be read by the CNC machine tools 200a, 200b through the data processing module 12 based on the NC program data set received from the CAM system 20 and the manufacturing data set received from the production control system 30, and transmit the job data set to the CNC machine tools 200a, 200b or their corresponding control devices 210a, 210b coupled thereto through the interface module 11.

In addition, the machine tools 200a, 200b can also be controlled via inputs at a corresponding user interface 213 of the control devices 210a, 210b.
