Showcase at the Hannover Messe demonstrated use cases

At this year's Hannover Messe, Dassault Systèmes demonstrated how work processes can be improved with the help of virtual environments, including Augmented Reality. For this purpose, a showcase was designed that demonstrates in four application areas on the shop floor how the virtual and real world merge and benefit from each other.

• Assistance in assembly: Through AR, instructions are directly projected onto a machine or component. This way, the employee knows what needs to be mounted where and how.

• Assistance in quality inspection: A camera system is directed at an object to be tested. The system scans the desired area and overlays in the image whether all product features meet the requirements. If this is not the case, the error is displayed on the component. In this way, defects in motors or casings can be identified, the positioning of elements such as sensors or wiring harnesses checked, or drillings controlled.

• Assistance in maintenance and service: The service employee receives clear instructions on-site for the maintenance of a control cabinet or a machine. Through AR visualization, it is precisely indicated which operations are to be performed in what order. Moreover, the employee confirms completed actions and can document any defects observed on-site.

• Automated quality inspection: For this purpose, a so-called Cobot is used. This term is a combination of the words "Collaboration" and "Robot". The Cobot moves over the parts to be tested or even an entire area and detects deviations thanks to sensitive sensors – consisting of 2D and 3D cameras. This is then compared with the target values defined in the digital model. Deviations are automatically recorded and documented, without the need for human intervention. The Cobot can be placed without protective devices and automatically moves over a machine according to instruction – no matter how large it is and how inaccessible the components are. Knowledge of robot programming is not necessary. Information from the virtual twin can be loaded directly into the system, and the Cobot "knows" what to do.

Productivity increases, the error rate decreases

The advantages of these application fields are clear: Processes can be carried out correctly on the first run. This significantly increases productivity and reduces the error rate. Furthermore, the improved workflow can reduce cycle and preparation times by up to 80 percent. Thanks to continuous and partially autonomous quality assurance, reliability and conformity are also ensured.

From practice: Augmented Reality in aviation

In a specific case, a manufacturer of aircraft engines and rocket motors for space exploration optimized its manufacturing processes. The company implemented the solution Delmia Apriso, which allows for the creation, management, and control of model-based, data-driven process workflows on a global scale. This significantly sped up the development and production process and improved traceability – a crucial competitive advantage when it comes to resolving engine problems. Augmented Reality is also used here in the search for faults. The "Picking" feature enables the capture and labeling of defects within the 3D model. This supports correction and the creation of inspection reports.

Sustainable change in the industry

Augmented Reality is a groundbreaking technology that manufacturing companies should not overlook. By supplementing real scenes with virtual information, a wide range of application areas opens up. Primarily, this use of data relieves the workforce in their daily work. The use of AR is sustainable, efficient, and puts people at the center. Companies that integrate AR into their workflow also benefit from increased productivity, reduced susceptibility to errors, and enhanced quality assurance. Thus, Augmented Reality has the potential to sustainably change the industry.
