Power Tools

Academic Staff

Topics and Focuses

At the Chair of Power-Tools and Machine Elements, we develop methods to support the development process with a focus on the specific challenges of the power tool industry. One focus is the development of measurement, modelling and validation methods based on the IPEK-XiL. We consider the user, application and power tool systemically integrative. Our aim is to explore methods and processes to support the product development of systems in which technical systems and humans interact directly with each other. In particular, we concentrate on machines where people are in the flow of power. In the development of measurement, modelling and validation methods, the understanding of the overall system, consisting of man, machine, environment and application, plays a decisive role. This understanding is the basis for the derivation of the design target variables for the individual machine elements used in the product and a driver for innovations in device technology.
