Based on a standard operating procedure from the Institute for Production Management, Technology, and Machine Tools (PTW) at the Department of Mechanical Engineering, a mixed reality learning scenario was collaboratively developed for introducing the operation of the Deckel Maho DMC 50H horizontal milling center in theCiP Learning Factory (opens in new tab). The scenario was implemented by the fuels team.

The Deckel Maho DMC 50H is a milling machine available at the Process Learning Factory CiP on the Lichtwiese campus. It plays a crucial role in the manufacturing industry, particularly in metal processing. With its capabilities, precisely milled components can be produced, making it an essential tool in production technology.

The learning scenario aims to qualify student assistants in the safe operation of the Deckel Maho DMC 50H horizontal milling center. It is designed to support training in the processes required for manufacturing milled components. In this specific application, the focus is on producing cylinder bases for pneumatic cylinders of varying lengths and sizes, as manufactured by the company “Festo”.

Methodologically, this is a linear-guided scenario. The detailed work instructions train users in the commissioning and execution of the milling process for cylinder bases. The scenario is created using the tool “.werkzeug”, which was developed by the fuels-Team at TU Darmstadt. The editor is designed to generate linear scenarios for digital or virtual content representation. During the training, the HoloLens 2 is used for support. It enables learners to experience the training content interactively and in an immersive environment, preparing new student assistants for operating the machine. The digitally supported training allows learners to acquire the necessary skills to operate the milling machine efficiently and safely. Additionally, it helps them develop the ability to manufacture milled components—particularly cylinder bases for pneumatic cylinders—ensuring compliance with quality standards in production.

A key benefit of this scenario lies in the integration of new technologies, which enhance the motivation of training participants. The use of the HoloLens 2 engages learners in an interactive and engaging learning environment. This not only improves training efficiency but also helps relieve instructors from routine tasks.
