The consideration of energy-related parameters is already in the planning phase an important step towards an energy-autonomous factory. Using Virtual Reality (VR) gives planners an important basis for decision-making with regards to drafting the layout. This potential should also be used for incorporating energy-related parameters. This paper introduces the coupling of a 2D planning system with a VR environment as the basis for the development of an energy-sensitive planning system. A prerequisite for considering energy-related parameters is recording and visualizing them. Therefore, the second part of the paper deals with energy visualization within a machine at the micro level.

This paper deals with the combination of micro milling and laser micro structuring for processing hot embossing dies for microfluidic applications. This strategy permits the advantages of each process technology to be exploited in order to achieve a cost and time efficient process and also to process forms and structures which cannot be manufactured with the single processes micro milling and laser micro structuring. Basic requirements are a high-precision positioning of the single process areas and also a good machining of the parts and structures with the manufacturing processes micro milling and laser micro structuring. The intersections between the different processing areas present a challenge for this process technology.

This paper describes the laser micro structuring of formingtools for hot embossing. The laser micro structuring allows the manufacturing of the required structural sizes and structure forms as well as the machining of the applied tool materials which can not be manufactured with conventional processes like milling. Through the systematic investigation of the influences of single laser parameters it is possible to influence the processing of 2-D and 2 1 2 -D micro fluid geometries. For initial experimental investigations the high strength ceramic material silicon carbide is used.

For a specific manipulation of friction surfaces it is important to measure and calculate geometrical parameters to derive the tribological behavior. The new functional approach presented in this paper is the calculation of the characteristic lateral extension of the real contact surface as well as the representative contact radius by applying morphological filters to a 3D-set of data. All surface characteristics, including form, waviness, roughness as well as defined microstructures, are extracted holistically with a 3D Coordinate Measuring Instrument or a Form Measuring Instrument, but with the smallest available tip radius. The paper presents the benefit of this holistic extraction method and the application of morphological filtering for the description of the contact form (plateau or sphere), the real contact surface, number of contacts, the typical contact radius and the typical lateral extension of the micro contact plateaus.

The ongoing miniaturization of milling tools leads to challenges particularly with regard to the selection of suitable machining strategies. Especially when machining high strength materials, significant problems in ensuring reliability and repeatability of the machining process are detected. Through the optimal selection of the machining strategy and the associated process parameters, improved accuracy and surface quality of moulds and prototypes can be achieved.
