The digital twin – a comprehensive virtual image of product and production

We enable the digital twin to be used in production: product data, supplemented by models, operating and process data, provides a comprehensive and dynamic image of a real product. It creates the basis for carrying out retrospective analyses as well as making statements about the future of a product.

By enriching the digital twin with more and more current (measurement) data, a detailed digital image is created that enables even more reliable statements and forecasts. For example, services for tracking products can be developed, usage analyses can be carried out or predictive statements can be made for better and more timely maintenance.

We are working on various solutions for production processes in turbomachinery manufacturing that can reduce or even completely avoid costly manufacturing errors:

The data collected from the design and development of the complex engine components serves as the basis for the virtual image. All production and sensor data is stored individually for the respective product in the digital twin, so that it carries the complete production history including project and order data.

The extended models with product, production and usage data are available for analysis and accelerate process development and optimization in individual and series production.

In the event of maintenance work, the current status of the component can also be recorded and analyzed using the data stored in the virtual model.

The digital twin enables efficient process design in glass forming

Glass forming is an established, efficient manufacturing process for the replicative production of complex-shaped glass optics. During the production process, however, thermal and material influences often lead to a non-tolerable shape deviation of the glass components.

To avoid this shape deviation, Fraunhofer IPT has developed a numerical simulation tool for glass forming. Using the simulation, geometric deviations such as glass shrinkage and optical changes such as the "index drop" can be predicted for the first time and it is possible to realistically map the design of the mold inserts and process control in advance of production. In this way, the use of the simulation tool can significantly reduce product development costs.

Comprehensive models for predicting the forming result

In order to take all relevant influencing factors of the process into account in the simulation, Fraunhofer IPT is carrying out fundamental work to develop a comprehensive process model.  This includes the implementation of a viscoelastic deformation and material model as well as a thermal model that describes the non-uniform temperature distribution within the glass and the tool. Based on extensive test series, Fraunhofer IPT has precise knowledge of the material properties of optical glasses and the corresponding tool materials.

The digital product twin improves battery cell production processes

Digital product twins in battery cell production enable structured consolidation and management of data, information and models that are assigned to a specific instance of a physical intermediate or end product, for example an electrode roll or a battery cell. Descriptive and technical product data is merged in a global data structure and semantically linked. This allows the structure and configuration of the product to be digitally mapped and enriched and linked with data on external environmental influences and relevant process data. Examples include machine parameters from individual processes such as target values for the calender gap or sensor values that are recorded during individual production steps.

The digital product twin makes it possible to create a virtual representation of the products that evolves dynamically across the entire battery cell production process chain. In this way, all information on materials, framework conditions and production steps of the product can be tracked in detail. The findings from this not only support effective quality assurance, but also allow systematic feedback of product quality features with specific production parameters. In this way, potential improvements to products and processes can be identified and product quality can be continuously improved. The digital product twins make it possible to view the properties of all intermediate products involved as well as process data from upstream production steps in much greater detail than before. Only through this linking is it possible to influence the production environment in a context-sensitive manner.

A special feature of the digital product twin is the large number and variety of intermediate products that have to be referenced with each other. These include the electrode pastes and the electrode roll for the anode and cathode, which are combined in the digital twin of the battery.

From the digital representation to the real fiber composite component

The use of digital strategies to predict product quality does not stop at semi-finished products made from fiber composite materials. In order to make the machining processes of thermoplastic and thermoset materials more efficient and sustainable, it is necessary to record and evaluate production data and define optimum target parameters. The digital image can be used for this task.

For the production of pressure tanks made of fibre composites, we use the digital shadow to optimize the production process along the component and ensure component quality.

In thermoplastic tape laying, constant process conditions such as uniform temperature distribution must be present for optimum production results so that residual stresses in the component are kept to a minimum. The digital image can be used to derive optimized taping strategies for homogenizing the temperature. This ensures that the thermoplastic tapes are processed into components of the highest quality.

If you have any questions about the use of a digital twin in fiber composite technology, please contact Henning Janssen.

The digital plant twin provides information about production processes and enables predictive maintenance

One area of application for the digital twin is in the representation of machines and systems in production. One example of this is the presentation of information and data in a dashboard that serves as a human interaction point. During a process, the data is recorded directly in the machine and merged in a time series database.

In addition, 3D models of the machine can be rendered or pre-rendered for use. This information and data visualizes the current status of the equipment, which can be read on the PLC HMI of the machine itself or standing in front of the machine. By using additional information about the equipment and the machine process, key figures about the machine performance and the stability of the machine process can be calculated. In this way, a range of different data from different sources can be used in targeted data processing steps to create a helpful summarized display for users in production.

This simple form and implementation of the digital twin already allows essential live conclusions to be drawn about the physical object, so that process parameters - which are still largely manual today - can be adjusted. Further use cases that build on this application scenario are already part of predictive and prescriptive analytics, such as the predictive maintenance of wearing parts or fully automated, adaptive process control.

The digital building twin maps the information that is important for the construction of a factory building: In addition to sensors and IT systems, the data basis includes plans, models, drawings, material and supplier data, environmental and sensor data as well as field and user data. The two biggest challenges here are the high number of different stakeholders in construction operations and the heterogeneity of the available data sources. Unified exchange platforms can create synergies and provide uniform access points and standards for processing information.

The digital twin can provide various services for the user: For example, construction progress can be continuously monitored during the construction phase of a project. In addition, virtual inspections offer high added value for the project partners at an early stage. The optimization of planning statuses and the automatic adjustment of factory layouts and material flows also help to better organize real construction activities.

The factory twin not only offers added value through a better exchange of information right from the planning stage, but also through virtual inspections during the construction phase. Operators also benefit during the use of the building through a variety of options for holistic optimization of the environmental parameters of their production, for example through automated conditioning of clean and dry rooms.

The benefits of the digital twin for the manufacturing industry

Better control, monitoring and optimization of products and processes: By using all product-related data and with the help of predictive simulations, companies increase their production efficiency and product quality, while reducing manufacturing and service costs and creating capacities to prepare for the challenges of the future.

Product development

The digital twin of a product can be used for virtual tests and simulations in order to optimize the design, make performance predictions and detect product defects at an early stage. This reduces development costs and time-to-market.

Maintenance and servicing

The digital twin provides information about the condition and performance of a product in real time: data analyses can be used to detect anomalies or wear and tear and initiate maintenance. This reduces downtimes, extends the service life of products and increases their efficiency.

Process optimization

Another field of application for digital twins is the optimization of production and business processes: By analyzing production data, bottlenecks can be identified, processes improved and efficiency increases achieved. This reduces costs and increases productivity.

Virtual commissioning

With a digital twin, systems and production lines can be tested and optimized virtually before they are physically set up in reality. In this way, weak points and bottlenecks can be identified and eliminated at an early stage, saving time and costs.

Education and training

Digital twins can also be used for training courses. Employees learn to master complex tasks in a virtual environment or can practise certain scenarios. This reduces training costs and increases the effectiveness of training courses.
