The digital twin is the key to the Factory of the Future – Part II
Guest Contributor: Hans Michael Krause, Bosch Rexoth
The modular assembly line of Dassault Systèmes and Bosch Rexroth presented at the Hannover Messe is the result of a change in perspective. Planning production processes coming from the product, instead of the machines – that is what the digital twin can put into effect. Marketplaces for digital twins, IoT Gateway software and open standards will mark the route into the factory of the future.

The demo assembly line from Bosch Rexroth shows how digital twins completely reverse the logic of production, if you think of the Factory of the Future. It is no longer the machines that determine the processes, but the products. A customer’s order automatically leads to the creation of a digital twin. This is connected, for example via an RFID chip as a reference to the blank to inform the machines later about the respective processing steps. As a crucial precondition for this evolution, Bosch Rexroth has already created behavioral models for many automation components, which are available on request for systems engineering. As part of the online configuration, customers already receive the CAD models of the components in the appropriate data format automatically.

Next evolutionary step: Marketplaces for digital twins

In a future scenario that is interesting for mechanical engineers, digital twins could be made available from automation components but also via a marketplace in order to bring them into the simulation environment with a single click. As a result, the OEMs could parameterize the automation immediately, test it and put the entire model into virtual operation quickly and safely. In addition, the marketplace could become a PLM platform, where all digital twins for current and past solutions are available. To prepare for this scenario, Bosch Rexroth is currently seeking a dialog with its customers in order to jointly define the exact requirements for the simulation models.

Pioneering: IoT Gateway software and open standards

In order to achieve continuous improvements in production using the digital twin, the real operating data from the assembly line can be compared with its simulation. This allows the quality of the manufacturing process to be monitored in real time and the maintenance to be modeled and optimized based on the current condition. The assembly line shown at the Hannover Messe also depicts the current state of the art in this respect. The IoT Gateway software from Bosch Rexroth, which is installed on a pocket-sized box PC, collects data from the controller via the Industry 4.0 standard OPC UA and transfers it to a higher-level IT system for visualization and analysis using 5G technology. With regard to the investment security of IoT solutions, Bosch Rexroth consistently relies on open standards such as OPC UA.

In future, it is no longer the machines that determine the processes, but the products.

Important stage on the way to the Factory of the Future

Dassault Systèmes’ and Bosch Rexroth’s partnership is a powerful testament to the competitive advantages that machine builders and end users derive from a seamless workflow, from virtual engineering to intelligent automation. The digital twin of the demonstration line not only forms the basis for the fastest possible start-up, but also for the quickest possible production changeover and easy continuous process optimization with the help of IoT services. The close partnership of both companies is another stage win along the way to the Factory of the Future.

With Digital Twin to the Factory of the Future – Part I

Guest contributor: Hans Michael Krause, Bosch Rexroth

Bosch Rexroth and Dassault Systèmes will use a modular assembly line to show how the Factory of the Future can be efficiently planned, implemented and continuously improved using digital twins. The key ingredients for this recipe for success: model-based systems engineering, intelligent controls and drives with open interfaces, and continuous improvement through IoT services.

Manufacturers of complex products and machines face the challenge of meeting the most diverse requirements in even shorter development cycles. With a demonstration assembly line, Dassault Systèmes and Bosch Rexroth will show at the Hannover Messe how time-to-market can be shortened with the greatest possible flexibility if production and product engineering seamlessly mesh on the data side. In addition, the turnkey assembly line highlights the added value that machine builders and end users can generate in conjunction with IoT services. The cornerstone of all this is the ‘digital twin’, a realistic depiction of product, production and performance.

At the Hannover Messe, Bosch Rexroth and Dassault Systèmes will demonstrate the seamless and profitable interaction of line and product engineering.

“Single source of truth” for the product, production and performance

Dassault Systèmes integrates the sample project from Bosch Rexroth into the integrated engineering workflows of the 3DEXPERIENCE platform, which provides a central source of information for designers, electricians and programmers. All platform functions for virtual engineering access a common database. For example, the simulation software receives direct access to the design data from the CAD program. In addition, it enables visualization in real time, so that visitors to the Bosch Rexroth booth can observe the 3D model of the demo line connected with the real object in real-time via sensors.

Shortened initial start-up through model-based engineering

The demo assembly line has a modular structure and is based on intelligent, decentralized automation components that are networked horizontally and vertically via open standards. The product that is assembled on the assembly line, the SCD – Sense Connect Detect sensor introduced by Bosch Rexroth, controls itself along the line using an RFID identifier. As in previous projects, such as the WestRock packaging machine, this system has also been developed, put into virtual operation and implemented in a very short time using models in the framework of Dassault Systèmes’ 3DEXPERIENCE platform. In addition to the CAD data, the behavioral models from the automation also flowed into the digital twin.

Collaboration between production and product engineering

The 3DEXPERIENCE platform also acts as an interface to the end user. If the user also depicts a product using a digital twin, the system can adjust to their requirements within a short time. An example: a manufacturer of construction vehicles wants to use the SCD sensor in a future excavator to measure vibrations from the hydraulic pump. He uses the sensor model in the virtual prototype of the excavator and defines a required housing modification. Bosch Rexroth then creates a new digital twin, inserts it into the virtual line model and validates the production capability in the simulation environment. In the same way as in this example, machine builders can use their digital twins to test in advance how new variants affect space requirements, stability, geometry, storage life or transport. In addition, the simulation also exposes critical areas for product quality, thereby reducing the risk of product recalls.

Economical production of batch sizes of 1

The close interlinking of product, production and performance via digital twins also allows for much more flexibility in production. This aspect is also illustrated by the joint demo project from Bosch Rexroth and Dassault Systèmes. To economically produce different sensor variants in small quantities down to a batch size of 1, Dassault Systèmes’ 3DEXPERIENCE platform works with the system via its MES functions. It transmits the jobs individually to the assembly line via the OPC UA interface, and from there receives the production and quality data for each manufactured SCD sensor.

Dassault Systèmes’ and Bosch Rexroth’s partnership is a powerful testament to the competitive advantages that machine builders and end users derive from a seamless workflow, from virtual engineering to intelligent automation.
