Online analysis and visualization of a machine tools energy flows
To enable the operators in optimizing the energetic performance of the machines, they require direct feedback of the machines current and average energetic behavior. At inspire/IWF, an approach to visualize the energetic behavior of machine tools based on a minimal set of measurement in combination with physical models has been demonstrated successfully.

Energy flows
From an environmental point of view, machine tools are active products: The dominant re-source and energy demand takes place during the machine’s operation. The energy demand – e.g., the energetic behavior – is thereby highly dependent on the operational schedule and the operator’s inputs. To enable the operators in optimizing the energetic performance of the machines, they require direct feedback of the machines current and average energetic be-havior. At inspire/IWF, an approach to visualize the energetic behavior of machine tools based on a minimal set of measurement in combination with physical models has been demonstrated successfully. The question is, how this approach can be systematically transferred to ma-chine tools and runed on the machines’ industrial PC.

Goal of this student thesis is the transfer of the existing theoretical concepts for the real time analysis and visualization. To do so, the existing concepts must be evaluated with respect to technology (e.g., what can be implemented on the existing industrial PCs connected to ma-chine tools?) and economy (e.g., what can be afforded sensors wise?). Based on these in-termediate results, a technological concept must be designed and implemented. The thesis requires the following tasks:
• Literature review of the existing energy demand prediction and visualization con-cepts
• Concept for the implementation of an online prediction and visualization concept
• Integration and implementation on a provided target system
• Verification and validation of the resulting integration
• Documentation and presentation of the results
