Description

Technical field of the invention

[0001] The present invention relates to a method for setting up a manufacturing process for a component and to a manufacturing system for producing a component. Background of the state of the art

[0002] During the production preparation phase, it is common practice to simulate the process, taking into account the most relevant process parameters. Statistical analyses are used to test the robustness of a single production process; however, tolerance ranges across multi-stage production processes are largely ignored. This is because combinatorial analysis is far too complex and would likely reveal that a worst-case scenario simply wouldn't work. The solution is to narrow down the tolerances of the parameters of both the component being manufactured and the manufacturing process to ensure that the functional requirements are met under all conditions. However, this can be a significant driver of increased manufacturing costs.

Depending on the deviation of the actual shape from the target shape, the tool is automatically controlled. Summary of the invention

[0009] It may be an object of the present invention to design and control a manufacturing process precisely without the need to consider limiting tolerances for component parameters and process parameters.

[0010] The problem is solved by a method for setting a manufacturing process for a component to be manufactured and by a manufacturing system for producing a component according to the subject matter of independent claims 1 and 15.

[0011] According to a first aspect of the present invention, a method for setting up a manufacturing process for a component to be manufactured is provided. According to the method, setting values ​​of operating parameters are determined by a first manufacturing station of the manufacturing process (for example, by measuring or by predefining), wherein the first manufacturing station is set up to treat the component according to the determined operating parameters.

[0012] Furthermore, values ​​of inherent parameters of the component are determined (for example, by measuring or by predefining) that are indicative of inherent component properties of the component before the component is treated in the first manufacturing station by a component unit.

[0013] Furthermore, a behavioral function of the component is configured by coupling a component unit with the determination unit and the control unit. The behavioral function defines the functional relationship between the inherent parameters of the component and the operating parameters of the first manufacturing station. Through this behavioral function, setpoint values ​​for the operating parameters of the first manufacturing station are determined, enabling predefined resulting values ​​of the inherent parameters to be achieved.

[0014] Based on the determined settings for the operating parameters, the operating parameters of the first production station are set.

[0015] The inherent parameter is determined in real time during the processing of the component in the first manufacturing station. According to the procedure, a real-time inspection of the processed component is provided in a test procedure of a test simulation tool, whereby the simulation tool virtually recreates a model of the processed component and tests are virtually simulated in the simulation tool in real time.

[0016] The procedure further describes the step of analyzing whether the component under test meets specific test requirements. If the component does not meet these requirements, the procedure proceeds to determine, in real time, the modified resulting values ​​for the component's inherent parameters that would allow it to meet the test procedure. These modified resulting values ​​are defined as the desired modified values ​​of the inherent parameters after the component leaves the first manufacturing station. The procedure includes determining these values ​​by the behavior function of modified settings for the operating parameters at the first manufacturing station, which enable the modified resulting values ​​of the component's inherent parameters to be achieved.

[0017] According to a further exemplary embodiment, a manufacturing system for producing a component is presented. The manufacturing system comprises a first manufacturing station, which is configured to treat the component by means of operating parameters, and a control unit, which is configured to determine setting values ​​for the operating parameters of the first manufacturing station of the manufacturing process.

[0018] The manufacturing system also includes a component unit that is set up to determine values ​​of inherent parameters of the component that are indicative of inherent component properties of the component prior to the treatment of the component in the first manufacturing station.

[0019] The manufacturing system further comprises a determination unit configured to configure a behavior function of the component. This determination unit is coupled to the component unit and the first control unit (e.g., via communication channels). The determination unit is configured to determine, through the behavior function, setpoint values ​​for the operating parameters of the first manufacturing station, thereby achieving predefined resulting values ​​of inherent parameters. The operating parameters of the first manufacturing station are adjustable by the control unit based on these determined setpoint values. The determination unit is configured to determine the inherent parameters in real time during the processing of the component in the first manufacturing station.The manufacturing system also includes a simulation tool configured to test the treated component in a real-time simulation test procedure, wherein the simulation tool virtually replicates a model of the treated component and tests are virtually simulated in the simulation tool in real time, allowing analysis of whether the treated component meets specific test requirements, and if the tested component does not meet the specific test requirements.

[0020] The determination unit is configured to determine in real time modified resulting values ​​for the inherent parameters of the component with which the processed component meets the test procedure, wherein the modified resulting values ​​for the inherent parameters of the component are defined as the modified desired values ​​of the inherent parameters after leaving the first manufacturing station, and the determination unit is configured to determine, by the behavior function, modified setting values ​​for the operating parameters for the first manufacturing station, by which the modified resulting values ​​of the inherent parameters of the component are achievable.

[0021] A manufacturing station describes a station into which a component can be inserted or through which it can pass, whereby its inherent parameters (such as microstructure or geometry) are modified during processing. Examples of manufacturing stations include: furnaces for tempering the component, quenching devices, stamping devices, press hardening devices, die-cutting devices, welding devices, and conveying devices for transporting the component; a temperature control device for controlling the component's temperature; a mold; or a joining device, such as a welding station.

[0022] Each production station is set up to process the component with specific operating parameters. For example, each production station is configured to operate with these parameters. These parameters can be obtained from simulation tools that simulate a manufacturing process or through measurement. Examples of operating parameters include treatment temperature, treatment atmosphere, treatment time, throughput speed, forming speed, component tempering rate, and ambient conditions of the first production station, such as humidity and temperature.

[0023] The component possesses inherent parameters that are indicative of its inherent properties. These inherent parameters can include, for example, component material, component size, component microstructure, component shape, component weight, and physical properties such as tensile strength, modulus, melting point, and / or surface roughness. The inherent parameters describe, for example, the inherent properties of the component. These parameters can be measured or predefined using simulation tools, thus partially forming a digital twin of the component. The inherent parameters can be obtained through simulation tools, measurements, and other methods.

[0024] The behavior function defines the functional relationship between the inherent parameters of the component and the operating parameters of the first manufacturing station (and / or other manufacturing stations of the manufacturing system). The behavior function determines setpoints for the operating parameters of the first manufacturing station that allow predefined resulting values ​​of the inherent parameters to be achieved.

[0025] The resulting values ​​of the inherent parameters are defined as the desired predefined values ​​of the inherent parameters of the component after a certain time during treatment in a manufacturing station or after leaving the manufacturing station.

[0026] According to the approach of the present invention, the functional relationship between the inherent parameters of the component and the operating parameters of the manufacturing station is designed. The behavioral function is a process or relationship that maps the interdependencies between the inherent parameters and the operating parameters of the manufacturing station. The behavioral function provides a functional evaluation of the component, for example, within and after the manufacturing station. The behavioral function considers the behavior and thus the functional dependencies of the inherent parameters as they are influenced by the operating parameters in the manufacturing station. Additionally, the behavioral function considers the functional dependencies between the inherent parameters themselves and / or the functional dependencies between the operating parameters of a single manufacturing station and / or between operating parameters of different manufacturing stations.

[0027] For example, by treating the component with specific operating parameters, specific inherent parameters of the component can be determined or calculated by the behavior function. Furthermore, by providing specific values ​​for inherent parameters of the component, specific values ​​for the operating parameters can be determined by the behavior function. The term "behavior" describes how the component behaves when treated with specific values ​​of the operating parameters and how the inherent parameter changes during treatment. However, due to the functional relationship considered in the behavior function, it is also possible to determine specific values ​​for operating parameters to achieve the desired resulting value for the inherent parameters of the component.

[0028] Based on the resulting values ​​of the inherent parameters, determined by the behavior function, and considering the initial values ​​of the inherent parameters and the values ​​of the operating parameters of the manufacturing station, the operating parameters can be adjusted based on and in comparison to the determined setpoints for the operating parameters. For example, if the resulting values ​​for the inherent parameters do not match the desired result, the operating parameters of the manufacturing station can be changed so that the newly determined setpoints for the operating parameters result in a value for the inherent parameter that matches the desired result.

[0029] For example, if the first manufacturing station is an oven and the temperature operating parameter is set to 750°C, the resulting value for the component's inherent parameter, such as its microstructure, can be determined by the behavior function. If the resulting value for the component's microstructure does not match the desired value, the temperature operating parameter can be changed, for example, by increasing the temperature setting to 850°C. Based on this setting, the resulting value of the component's inherent parameter can be recalculated until the desired value, such as a specific type of microstructure, is achieved.

[0030] As another example, if it is first determined that the thickness, as an inherent parameter of the component, has a specific value (thickness), the behavior function calculates a resulting value of an inherent parameter (for example, a core temperature of the component) under a specific setting (for example, temperature) of the operating parameter temperature. The behavior function can calculate whether the processing time in the manufacturing station or the temperature of the manufacturing station needs to be changed, taking the component thickness into account, to achieve the predefined resulting values ​​for the inherent parameter (for example, core temperature) of the component.

[0031] Thus, the approach of the present invention enables a wide range of individualization options for manufactured components with their specific property concepts. In addition to trend analysis of component properties, predictive plant control during operation, and predictive maintenance, measures can be taken to verify the effectiveness of monitored process parameters or component function in real time by considering the functional relationship and using the behavioral function. Furthermore, with valid virtual components, it is possible to implement a virtual acceptance test at the plant manufacturer without relying on the limited availability of standard production components, and even the manufacturability of complex assemblies, such as complete vehicles, can be ensured long before the components arrive at the factory.

[0032] The control unit, for example, forms the control system of the production station, which receives information about the setpoint values ​​of operating parameters. The component unit is configured to receive inherent parameters of the component or to determine, in particular simulate or calculate, the values ​​of inherent parameters of the component. The determination unit operates the behavior function and is configured to receive the respective values ​​of the inherent parameters of the component and the operating parameters of the respective production station.

[0033] Furthermore, the determination unit is configured to transmit the calculated setpoint values ​​for the operating parameters to the control unit. The control unit, the component unit, and the determination unit can be coupled via communication channels to exchange the necessary data for the respective parameters. These communication channels can be wired or wireless. The control unit, the component unit, and the determination unit can be controlled by a microprocessor. Accordingly, in an exemplary embodiment, the method for setting a manufacturing process can be a computer-implemented method.

[0034] Accordingly, the manufacturing system comprises the control unit, the component unit, and the destination unit, with each unit including or having a unique data processor for performing the procedure for setting a manufacturing process for a component, as described above. The procedure for setting the manufacturing process for a component can also be considered a computer-implemented procedure.

[0035] According to another exemplary embodiment, the values ​​of the operating parameters of the first production station are (for example, initially) predetermined. The setpoint values ​​of the operating parameters of the respective production station can be specified, for example, by a virtual process such as a production planning process (PPP). Target setpoint values ​​of operating parameters can be stored in a database or calculated by simulation tools.

[0036] The operating parameters can be predefined (for example, initially set once), but can be modified later by the behavior function during processing of the component at the respective production station. For example, predefined operating parameters, such as temperature, might result in an excessively high tensile strength. Therefore, the behavior function determines the temperature as an operating parameter at which the desired lower tensile strength, as an inherent parameter of the component, can be achieved before the component is transferred to a subsequent production station. The behavior function is configured based on the functional relationship between tensile strength and temperature at the production station.

[0037] Furthermore, the temperature of the component changes constantly during processing, particularly during the heating of the production station, and consequently, the component's tensile strength also changes constantly. The tensile strength (i.e., the inherent parameter) can be simulated in real time in parallel with the temperature changes (operating parameters). The behavioral function can also take into account other inherent parameters, such as the type of component material, so that precise values ​​for inherent parameters (like tensile strength) and, based on these, precise values ​​for operating parameters can be determined continuously in real time to achieve the desired inherent parameters of the component. Thus, the ongoing manufacturing process can be continuously adjusted in real time.

[0038] According to another exemplary embodiment, the values ​​of the operating parameters of the first production station are measured by operating sensors before, during, and / or after the processing of the component. In addition to or as an alternative to the predefined operating parameters, corresponding operating sensors can measure the operating parameters while the component passes through the production station. This allows for real-time measurement of the operating parameters. The operating sensors include, for example, temperature sensors, atmospheric sensors, or monitoring sensors such as camera systems (e.g., infrared or CCD cameras).

[0039] According to another exemplary embodiment, the values ​​of the inherent parameters are predefined before the component is processed at the first manufacturing station. Thus, the values ​​of the inherent parameters can be defined by target values, which are stored, for example, in a database, and / or provided by a virtual component (digital twin) of the component to be manufactured. The target values ​​can be provided by simulation tools, such as a model of a product development process (PDP).

[0040] According to another exemplary embodiment, the values ​​of inherent parameters are measured before the component is processed in the first (or before a second) manufacturing station, particularly by component sensors. This allows the values ​​of the inherent parameters to be measured, enabling the precise initial values ​​of the inherent parameters to be determined in reality before the component enters the manufacturing station. Thus, the behavioral function allows the operating parameter settings to be adjusted based on a measurement of an initial inherent parameter of the component.

[0041] According to another exemplary embodiment, the operating parameters for the first manufacturing station, with which predefined resulting values ​​of inherent parameters of the component can be achieved, are determined (for example, by sensors) during processing of the component within the first manufacturing station. Thus, if a setting value of an operating parameter does not match a predefined setting value below which the predefined resulting values ​​of inherent parameters can be achieved, the setting value of the operating parameter can be adjusted inline (i.e., in real time) before the component leaves the respective manufacturing station.For example, if the temperature in the manufacturing station is too low to achieve the desired inherent parameter (e.g., a desired microstructure of the component), the operating parameter setting can be adjusted using the behavior function so that the desired resulting values ​​of inherent parameters of the component can be achieved at the output of the manufacturing station.

[0042] The operating parameters can be changed in real time during the processing of the component at the respective production station if the parallel functional simulation, using the behavior function, indicates that the desired, predefined resulting values ​​of the respective inherent parameters of the component are not being achieved. Accordingly, a parallel comparison of actual and theoretical values ​​between, for example, a measured and a determined operating parameter is possible, allowing the operating parameters to be continuously corrected in real time. The target value for the operating parameter can be determined through simulation, and the actual value can be measured via sensors.

[0043] In particular, several determination cycles with the behavior function can be performed in real time during treatment of the component in a manufacturing station in order to achieve the desired, predefined resulting values ​​from the inherent parameters of the component.

[0044] According to another exemplary embodiment, the resulting values ​​of inherent parameters of the component are determined by the behavior function, taking into account the operating parameters for the first manufacturing station after treatment of the component in the first manufacturing station.

[0045] This means that the resulting values ​​of the inherent parameters are known, so that, as described below, the operating parameters for the preceding production station can be set to achieve the predefined resulting values ​​of the inherent parameters after the preceding production station. Furthermore, because the resulting values ​​of the inherent parameter are known, the operating parameters for a subsequent production station can be set to achieve predefined resulting values ​​of the inherent parameter of the component after the subsequent production station.Therefore, if the resulting values ​​of the inherent parameter of the component after the preceding manufacturing station do not match the predefined resulting values ​​after the preceding manufacturing station, the parameters of the subsequent manufacturing station can be set so that at least after the second manufacturing station the respective predefined resulting values ​​can be achieved.

[0046] As described above, according to an exemplary embodiment, the operating parameters of the first (preceding) manufacturing station are set based on the determined setting values ​​for the operating parameters for another component that is processed in the first manufacturing station after the component.

[0047] According to another exemplary embodiment of the method, the treated component is tested in a test procedure, and it is analyzed whether the treated component meets the specific test requirements. If the tested component does not meet the specific test requirements, modified resulting values ​​for the component's inherent parameters are determined, enabling the treated component to meet the test procedure requirements. Next, the behavior function determines modified setting values ​​for the operating parameters for the first manufacturing station (or for other or all manufacturing stations of the manufacturing process), such that the modified resulting values ​​of the inherent parameters can be achieved with these setting values.

[0048] According to another exemplary embodiment, the test procedure includes simulating a test of the component under investigation in a simulation tool. The simulation tool can, for example, perform a finite element analysis to simulate the component structure under specific stresses (e.g., crash tests).

[0049] According to another exemplary embodiment, the test procedure includes a physical inspection of the treated component. For example, tensile tests or crash tests can be carried out on the treated component to verify whether the resulting values ​​of the inherent parameters meet the required quality.

[0050] According to another exemplary embodiment, the modified resulting values ​​determined by the simulation of the test procedure are compared with the modified resulting values ​​determined by the physical test. The modified resulting values ​​determined by the simulation are corrected taking into account the modified resulting values ​​determined by the physical test. Thus, according to the present exemplary embodiment, results of the physical test procedure, such as a crash test procedure, can be compared with the virtual results of the test procedure performed in the simulation tool. If there is a discrepancy between the real test procedure and the virtual test procedure, corrections to the virtual simulation and the behavioral function, respectively, are possible.This allows a self-learning manufacturing system to be provided, and the operation of the respective manufacturing station can be discontinued.

[0051] According to another exemplary embodiment, the operating parameters of the first manufacturing station are set by a first control unit (such as a computer or control device of the first manufacturing station) based on the resulting values ​​of inherent parameters during and after the processing of the component in the first manufacturing station. This allows for real-time adjustment of the operating parameters. For example, if it is detected upon component entry that an operating parameter has changed—for instance, the temperature of the furnace at the first operating station has been lowered upon component entry—the behavioral function determines a temperature correction to still achieve the desired resulting component values.For example, the operating parameter "treatment time of the component in the oven" or the operating parameter "temperature" could be increased to compensate for the drop in oven temperature when the component is inserted. During the treatment of a component within a production station, a multiple determination cycles for changing the operating parameters based on different operating parameters and inherent parameters can be performed in real time by the behavior function.

[0052] According to another exemplary embodiment, further setting values ​​for additional operating parameters are determined by a second manufacturing station of the manufacturing process, wherein the second manufacturing station is configured to process the component with the determined operating parameters after the component has been processed by the first manufacturing station. Additionally, further values ​​of inherent parameters of the component are determined by the component unit after the component has been processed in the first manufacturing station. Next, setting values ​​for the operating parameters for the second manufacturing station are determined by the behavior function, through which predefined further resulting values ​​of inherent parameters are achievable in or after the second manufacturing station. The behavior function further determines the functional relationship taking into account the additional operating parameters of the second manufacturing station.

[0053] The exemplary embodiment described above outlines the possibility of considering multiple additional manufacturing stations. The behavioral function determines further setting values ​​for the second manufacturing station or further manufacturing stations in order to achieve the desired resulting value from the component's inherent parameters. In summary, the inventive method can either provide a determination of the resulting values ​​of a component after each manufacturing station, taking into account the operating parameters of that particular manufacturing station, or it can provide a determination of the resulting values ​​of a component after multiple manufacturing stations, taking into account the operating parameters of the multiple manufacturing stations.

[0054] According to another exemplary embodiment, after the component has been processed in the first manufacturing station by the component unit, further values ​​of inherent parameters of the component are determined (for example, by measuring or taking into account the measured settings of the manufacturing station during the processing of the component). Furthermore, these further values ​​of the inherent parameters of the component are compared with the predefined resulting values ​​of inherent parameters that were determined by the behavior function before the first manufacturing station.Then, corrected settings for the operating parameters of the first manufacturing station are determined by the behavior function based on a comparison of the subsequent values ​​of inherent parameters of the component, determined after the first manufacturing station, with the predefined resulting values ​​of inherent parameters determined before the first manufacturing station. Thus, by comparing the inherent parameters of the component determined after processing with the predefined resulting values ​​of inherent parameters determined before processing by the behavior function, the calculated error can be used to correct the behavior function and the settings of the operating parameters of the first manufacturing station, enabling more accurate and predictable processing of a subsequent component in the first manufacturing station.Particularly when the current manufacturing process in a production station is sufficiently slow and allows for control intervention (for example, temperature changes in an oven), the operating parameters for the processing of the current component can be modified. Especially in very fast manufacturing processes, the operating parameters for subsequent components are changed.

[0055] In addition, or alternatively, to determining corrected setting values ​​for the operating parameters of the first manufacturing station using the behavior function, it is also possible to determine setting values ​​for the operating parameters of the subsequent second manufacturing station based on a comparison of the further values ​​of inherent parameters of the component determined after the first manufacturing station with the predetermined resulting values ​​of inherent parameters determined before the first manufacturing station.

[0056] In summary, the approach of the present invention ensures compliance with the functional requirements (i.e., its inherent parameters) for each manufactured component during the manufacturing process itself, thus eliminating the need to adhere to the exact direct and indirect predefined tolerances and process requirements required by known manufacturing methods. This inventive approach employs an analysis of the behavioral function (e.g., through simulation), with its relevant and individual properties (e.g., operating parameters and inherent parameters), in parallel with the actual manufacturing process, and preferably within the actual cycle time. As a result, each produced component is linked to its production parameters due to the functional relationship and thus possesses its own unique fingerprint characteristics.This approach can be better compared to conventional production planning because precise parameter settings for the equipment can be determined, which is particularly efficient for small batches or sample production scenarios of lot size 1 or in the start-up phase of mass production.

Brief description of the drawings

[0058] The aspects defined above and further aspects of the present invention will become apparent from the exemplary embodiments described below and will be explained with reference to these embodiments. The invention is described in more detail below with reference to exemplary embodiments, to which, however, the invention is not limited. Fig. Figure 1 shows a schematic representation of a manufacturing system according to an exemplary embodiment of the present invention. Fig. Figure 2 shows a schematic representation of exemplary core steps of the method for setting up a manufacturing process according to an exemplary embodiment of the present invention. Fig. Figure 3 shows a schematic representation of a manufacturing system with three exemplary manufacturing stations and a functional test according to an exemplary embodiment of the present invention. Detailed description of exemplary embodiments

[0059] The representations in the drawings are schematic. It should be noted that similar or identical elements in different figures are labelled with the same reference symbols.

[0060] Fig. Figure 1 shows a schematic representation of a manufacturing system 100 and Fig. Figure 2 shows a schematic representation of exemplary core steps of the method for setting up a manufacturing process according to an exemplary embodiment of the present invention. The manufacturing system 100 for producing a component 102 is presented. The manufacturing system 100 comprises a first manufacturing station 110, which is configured to treat the component 102 with operating parameters, and a control unit 111, which is configured to determine setting values ​​for the operating parameters of the first manufacturing station 110 of the manufacturing process.

[0061] The manufacturing system 100 further includes a component unit 103, which is set up to determine values ​​of inherent parameters of the component 102 that are indicative of inherent component properties of the component 102 before the treatment of the component 102 in the first manufacturing station 110.

[0062] The manufacturing system 100 further comprises a control unit 104, which is configured to configure a behavior function of the component. The control unit 104 is coupled to the component unit 103 and the first control unit 111, and optionally to the further control units 121 of an exemplary second manufacturing station 120 (for example, via communication channels). The control unit 104 is configured to determine, through the behavior function, setting values ​​for the operating parameters of the first manufacturing station 110, by which predefined resulting values ​​of inherent parameters can be achieved. The operating parameters of the first manufacturing station 110 are adjustable by the control unit 111 based on the determined setting values ​​for the operating parameters.

[0063] In Fig. Figure 2 shows exemplary steps of the method according to the present invention. In step 201, the setpoint values ​​of operating parameters of a first manufacturing station 110 of the manufacturing process are determined (for example, by measuring or by predefining), wherein the first manufacturing station 110 is set up to treat the component 102 with the determined operating parameters.

[0064] Furthermore, in step 202, values ​​of inherent parameters of component 102 are determined (for example, by measuring or by predefining) which are indicative of inherent component properties of component 102 before the treatment of component 102 in the first manufacturing station 110 by the component unit 103.

[0065] Furthermore, in step 203, a behavior function of component 102 is established by a determination unit 104, which is coupled to component unit 103 and control unit 111. The behavior function determines the functional relationship between the inherent parameters of component 102 and the operating parameters of the first production station 110. The behavior function determines setpoint values ​​for the operating parameters of the first production station 110, enabling predefined resulting values ​​of the inherent parameters to be achieved.

[0066] Based on the determined setting values ​​for the operating parameters, the operating parameters of the first production station 110 are set.

[0067] Furthermore, in the exemplary embodiment of Fig. One further setting values ​​for additional operating parameters of a second manufacturing station 120 of the manufacturing process are determined by a control unit 121 of the second manufacturing station 120, wherein the second manufacturing station 120 is configured to process the component 102 according to the determined operating parameters after the component 102 has been processed by the first manufacturing station 110. Additionally, further values ​​of inherent parameters of the component 102 are determined after the component 102 has been processed in the first manufacturing station 110 by the component unit 103. Next, setting values ​​for the operating parameters for the second manufacturing station 120 are determined by the behavior function, through which predefined further resulting values ​​of inherent parameters can be achieved in or after the second manufacturing station 120.The behavioral function further determines the functional relationship, taking into account the additional operating parameters of the second production station 120.

[0068] Thus, the manufacturing system 100 can have multiple additional manufacturing stations. The behavior function determines further setting values ​​for the second manufacturing station 120 or further manufacturing stations 130 (see Fig. 3) to achieve the desired resulting value of the inherent parameter of component 102. In summary, according to the inventive method, either a determination of resulting values ​​of a component 102 after each production station 110, 120, 130 can be provided, taking into account the operating parameters of the single production station 110, 120, 130, or a determination of resulting values ​​of a component 102 after a plurality of respective production stations 110, 120, 130 can be provided, taking into account the operating parameters of the multiple production stations 110, 120, 130.

[0069] The behavior function defines the functional relationship between the inherent parameters of the component and the operating parameters of the first manufacturing station. The behavior function determines setpoints for the operating parameters of the first manufacturing station that allow predefined resulting values ​​of the inherent parameters to be achieved.

[0070] The resulting values ​​of the inherent parameters are defined as the desired predefined values ​​of the inherent parameters of the component after a certain time during treatment in a manufacturing station 110 or after leaving the manufacturing station 110.

[0071] By treating component 102 with specific operating parameters, specific inherent parameters of the component can be determined or calculated using the behavior function. Furthermore, by providing specific values ​​for the component's inherent parameters, specific values ​​for the operating parameters can be determined using the behavior function. Due to the functional relationship considered in the behavior function, it is also possible to determine specific values ​​for operating parameters to achieve the desired resulting value for the component's inherent parameters.

[0072] Based on the resulting values ​​of the inherent parameters determined by the behavior function, the initial values ​​of the inherent parameters, and the values ​​of the operating parameters of manufacturing station 110, the operating parameters can be adjusted based on and in comparison to the determined setpoints for the operating parameters. For example, if the resulting values ​​for the inherent parameters do not match the desired result, the operating parameters of the manufacturing station can be changed so that the newly determined setpoints for the operating parameters result in a value for the inherent parameter that matches the desired result.

[0073] The control unit 111 of the first production station 110 or the control unit 121 of the second production station 120, for example, form the control system of production stations 110 and 120, which receives information about the setpoint values ​​of the operating parameters. The component unit 103 is configured to receive values ​​of inherent parameters of component 102 or to determine values ​​of inherent parameters of component 102, in particular by simulation or calculation. The determination unit 104 operates the behavior function and is configured to receive the respective values ​​of inherent parameters of component 102 and the operating parameters of the respective production station 110 and 120. Furthermore, the determination unit 104 is configured to transmit the calculated setpoint values ​​for the operating parameters to the control unit 111 or 121.The control unit 111, 121, the component unit 103 and the determination unit 104 are coupled via communication channels to exchange the required data of the respective parameters.

[0074] The operating parameters of the first production station 110 are measured by operating sensors 112 before, during, and / or after the processing of component 102. Similarly, the operating parameters of the second production station 120 can be measured by second operating sensors 122 during and / or after the processing of component 102. In addition to or as an alternative to the predefined operating parameters, corresponding operating sensors can measure the operating parameters while component 102 passes through the respective production station 110 or 120. This enables real-time measurement of the operating parameters.

[0075] The values ​​of the inherent parameters prior to the processing of component 102 in the first (or before a second) production station 110, 120 are measured, in particular, by component sensors 113, 123, prior to the processing of component 102 in the respective production stations 110, 120. Thus, the values ​​of the inherent parameters can be measured so that exact initial values ​​of the inherent parameters can be determined in reality before entering the production station 110, 120. Therefore, the operating parameter settings can be adjusted by the behavior function based on a measurement of an initial inherent parameter of component 102.

[0076] For example, the operating parameters for the first manufacturing station 110, through which predefined resulting values ​​of inherent parameters of component 102 can be achieved, are determined during processing of component 102 within the first manufacturing station 110 (for example, by sensors 112). Therefore, if a setting value of an operating parameter does not match a predefined setting value through which the predefined resulting values ​​of the inherent parameters can be achieved, the setting value of the operating parameter can be adjusted inline (i.e., in real time) before component 102 leaves the respective manufacturing station 110 or 120.If, for example, the temperature in the manufacturing station is too low to achieve the desired inherent parameter (e.g., a desired microstructure of component 102), the operating parameter setting can be adjusted using the behavior function so that the desired resulting value of the inherent parameter of component 102 can be achieved at the output of manufacturing station 110, 120.

[0077] Furthermore, after the processing of component 102 in the first manufacturing station 110 by component unit 103, further values ​​of inherent parameters of component 102 are determined (for example, by measurement or by taking into account the measured setting values ​​of the manufacturing station during the processing of the component). These further values ​​of the inherent parameters of component 102 are then compared with the predefined resulting values ​​of inherent parameters determined by the behavior function before the first manufacturing station 110.Corrected setting values ​​for the operating parameters of the first manufacturing station upon return are then determined again by the behavior function on the basis of comparing the further values ​​of inherent parameters of component 102, which were determined after the first manufacturing station 110, with the predefined resulting values ​​of inherent parameters, which were determined before the first manufacturing station 110.Thus, based on the comparison between the determined inherent parameters of the component after treatment and the predefined resulting values ​​of inherent parameters determined by the behavior function before treatment, the calculated error can be used to correct the behavior function and the setpoints of the operating parameters in the first manufacturing station 110, respectively, so that a subsequent component treatment in the first manufacturing station 110 can be carried out more accurately and predictably, since the operating parameters of the current process can be set so that the current process can be controlled.

[0078] In addition to or as an alternative to determining corrected setting values ​​for the operating parameters of the first production station 110 by means of the behavior function, it is also possible to determine setting values ​​for the operating parameters of the subsequent second production station 120 on the basis of comparing the further values ​​of inherent parameters of the component 102, which were determined after the first production station 110, with the predefined, resulting values ​​of inherent parameters, which were determined before the first production station 110 or before the second production station 120.

[0079] Fig. Figure 3 shows a schematic representation of a manufacturing system 100 with three exemplary manufacturing stations 110, 120, 130 and a functional test 303, 304 according to an exemplary embodiment of the present invention.

[0080] In Fig. Figure 3 illustrates the concept of the present invention using an exemplary hot forming production process as an industrial reference process of the manufacturing system 100 and demonstrates the concept of a multi-stage production process in several manufacturing stations 110, 120, 130. The real production process is accompanied by a virtual process. The virtual process is synchronized with the real process so that sensor data from the machines (i.e., the manufacturing stations 110, 120, 130), the process, or the environment can be used directly by the process model as parameters in real time. This synchronization enables continuous validation of the virtual process models. For the overall system, it is irrelevant whether the process models are inherently numerical (e.g., FEM) or analytical (e.g., surrogate models).Active control of real processes can be integrated into the virtual process model in the same way through real-time co-simulation. The production stations 110, 120, and 130 are coupled to the product planning device or system 301 and / or the test simulation tool 302 via communication channels 309 for data transmission between the real and virtual stages.

[0081] The hot forming process shown serves as a reference application of a function-oriented process control according to the present invention.

[0082] Manufacturing stations 110, 120, and 130 each describe stations into which component 102 can be inserted or through which it can pass, whereby the inherent parameters (such as microstructure, tensile strength, or geometry) are modified during processing in manufacturing stations 110, 120, and 130, respectively. Examples of manufacturing stations 110, 120, and 130 include an oven (first manufacturing station 110) for tempering the component, a transfer system (second manufacturing station 120), and a stamping press 130.

[0083] The respective production stations 110, 120, and 130 are configured to process the component with specific operating parameters. Each production station 110, 120, and 130 is, for example, set up to operate with specific parameters. These parameters can be obtained from simulation tools that simulate a manufacturing process in the virtual process level, or by measurement using the respective machine sensors 112, 122, and 132. Examples of operating parameters include blank heating in the first production station 110, blank cooling in the second production station 120, and forming speed in the third production station 130.

[0084] The component has inherent parameters that are indicative of inherent component properties, such as tensile strength. These inherent parameters are changed during processing at manufacturing stations 110, 120, and 130. The inherent parameters of component 102 can be monitored by component sensors 113 and 123 (see...). Fig. 1) are measured or predefined by simulation tools of a virtual part, so that the inherent parameters partially form a digital twin of component 102.

[0085] For example, the first production station 110 is a furnace, and the temperature, as an operating parameter, has a setpoint of 750°C. The resulting value of the component's inherent parameter, such as the tensile strength of component 102, can be determined by the behavior function. If the resulting value for the tensile strength of component 102 does not match the desired value, the temperature in the first production station 110, as the operating parameter, can be changed so that the setpoint for the temperature in the first production station 110 can be increased to, for example, 850°C. Based on this setpoint, the resulting value of the component's inherent parameter 102 can be recalculated until the desired result for the inherent parameter, such as a specific type of tensile strength, is achieved.

[0086] The operating parameters of the manufacturing stations 110, 120, 130 are set by the respective control units 111, 121, 131 (such as a computer or control device of the respective manufacturing station 110, 120, 130) on the basis of the resulting values ​​of inherent parameters during and after the treatment of the component 102 in the respective manufacturing station 110, 120, 130.For example, input inherent parameters 305, which are initially determined before entering the first manufacturing station 110, input / output inherent parameters 306 between the second manufacturing station 120 and the third manufacturing station 130, and input / output inherent parameters 307 between the third manufacturing station 130 and the physical test 304 can be determined and made available as output of inherent parameters after the test 308 for the behavior function in order to determine operating parameters for the respective manufacturing stations 110, 120, 130.

[0087] This allows for real-time adjustment of operating parameters. For example, if it is detected that an operating parameter has changed upon the entry of component 102—for instance, that the temperature of the oven at the first production station 110 has decreased upon the entry of component 102—then the behavioral function determines a correction temperature that allows the desired resulting values ​​of the inherent parameters of component 102 to still be achieved. For example, the operating parameter "processing time of component in oven 110" or the operating parameter "temperature" could be increased to compensate for the temperature drop in oven 110 upon the entry of component 102.During the treatment of a component 102 within a respective manufacturing station 110, 120, 130, the behavior function can perform a multiple determination cycles in real time to change the operating parameters based on differing real or virtual operating parameters and differing real or virtual inherent parameters.

[0088] As another example, if it is initially determined that the thickness, as an inherent parameter of component 102, has a specific value (thickness), then the behavior function calculates a resulting value of an inherent parameter (for example, a core temperature of the component) under treatment with a specific setpoint (for example, the temperature) of the operating parameter temperature. The behavior function can calculate whether the treatment time in the first manufacturing station 110 or the temperature of the manufacturing station 110 needs to be changed, taking into account the thickness of component 102, in order to achieve the predefined resulting values ​​for the inherent parameter (for example, the core temperature or the tensile strength) of component 102.

[0089] The values ​​of the operating parameters of the first production station 110 or the second production station 120 can be specified, for example, by a virtual process operation, such as a production planning process (PPP), for the respective production stations 110, 120, and 130. Target values ​​for operating parameters can be stored in a database or calculated by simulation tools, such as a product planning device 301.

[0090] The values ​​of the inherent parameters prior to the processing of the component in the first manufacturing station 110 or in the subsequent manufacturing stations 120 and 130 are predefined. The values ​​of the inherent parameters can therefore be specified by target values, which are stored, for example, in a database and / or provided by a virtual component (digital twin) of the component to be manufactured. The target values ​​can be provided by simulation tools, such as a model of a product development process (PDP) operated in a component development device 302.

[0091] Furthermore, as is evident from the Fig.The treated component 102, as can be seen from section 3, is tested in a test procedure, and it is analyzed whether the treated component 102 meets the specific test requirements. If the tested component 102 does not meet the specific test requirements, the resulting values ​​for the inherent parameters of the component 102, with which the treated component 102 fulfills the test procedure, are determined. Next, modified setting values ​​for the operating parameters for the first production station 110 (or for other or all production stations 120, 130 of the production process) are determined by the behavior function, with which setting values ​​the modified resulting values ​​of the inherent parameters can be achieved.

[0092] For example, if the component (model) validation and fitting procedure (e.g., an end-of-line (EoL) or conformity-of-production (CoP) test) reveals that the tensile strength does not match a predefined tensile strength, the operating parameters of the preceding manufacturing stations 110, 120, 130 can be recalculated by the behavior function.

[0093] The test procedure includes, for example, simulating a test of the treated component 102 in a simulation tool 303. The simulation tool 303 can, for example, perform a finite element analysis to simulate the component structure under certain influences (e.g., crash tests) and to check whether, for example, the tensile strength is sufficient.

[0094] Additionally or alternatively, the test procedure includes a physical test of the treated component 102 by a physical test unit 304. For example, tensile tests or crash tests of the treated component 102 can be carried out to verify whether the resulting values ​​of the inherent parameters (e.g., tensile strength) meet the required quality.

[0095] The modified resulting values ​​of the inherent parameters of component 102, determined by the test simulation in the test simulation tool 303, are compared with the modified resulting values ​​determined by the physical test in the physical test unit 304. The modified resulting values ​​determined by the simulation are corrected taking into account the modified resulting values ​​determined by the physical test. Thus, results of the physical test procedure, such as a crash test procedure, can be compared with the virtual results of the test procedure performed in the simulation tool 303.Because such physical tests for the overall function of the component are sometimes not feasible as component-destructive end-of-line (EoL) tests, an analog model is created using simulation tools. The tests (e.g., the crash test) can be simulated virtually within this tool. The analog model is used for validating and parameterizing the component, and the crash simulation is used to set inherent component parameters and real-world parameters for the actual physical test. If there is a discrepancy between the real-world test procedure and the virtual test procedure, corrections can be made to the virtual simulation and the behavioral function. This enables the provision of a self-learning manufacturing system and allows for the shutdown of the respective production station.

[0096] The functional evaluation of the manufactured component 102 is performed virtually based on the existing digital component twin ("Digital Twin") with a functional model. The digital twin possesses all function-relevant properties, including those that cannot be measured on the real component in a timely, non-destructive, or cost-effective manner. Thanks to this evaluation, results from the virtual component evaluation versus the end-of-line (EoL) or conformity-of-production (CoP) inspection are translated using the function-oriented process model control parameters and transmitted to the machine controls via the function-oriented process control. This ensures that every produced part meets the functional requirements, even though the exchange inspection at the EoL / CoP station cannot fully confirm this, especially if a destructive test would be necessary.
