Item type:Publication, Produktionsbegleitende Messeinrichtung basierend auf digitaler Holografie(2019-03-08); ; ; For industrial mass production of micro parts it is important to detect the tool wear. To avoid long machine down time the measurement tool should be fast and it should be used inside the production machine. In this thesis a measuring system based on digital holography was developed. The set-up was designed as a digital holographic microscope to detect and characterise wear at micro deep drawing tools within a deep drawing machine. Furthermore, the basic idea of comparative holography was used to give the opportunity to generate a state difference of a worn tool and its initial state. Beside the measuring system an evaluation tool was developed. Here, both were evaluated by detecting a state difference of a die of an upsetting machine which shows material lost at the edges and surface after upset wires.doctoral thesisBand:0068802 285
