Emulsion-Process-Monitor in metal working processes EPM II

液态乳化液在金属加工过程中用作润滑剂和/或冷却液（切削液），如研磨或车削。在工业过程链中，由于在过程中的连续使用，所使用的乳液可能会偏离理想状态和组成。例如，由于物理、化学和/或生物过程，乳化相浓度或其液滴尺寸分布可能发生变化，或者乳液组分组成发生改变。金属加工过程中乳化液质量的控制是延长机器运行时间、保护环境和提高机器运行经济竞争力的重要课题。该项目旨在开发一种金属加工过程中的乳化过程监控器，可用于过程中和在线控制乳化液的稳定性和质量。静态光散射、衍射和光谱法等非侵入性计量技术以有针对性的组合方式用于评估乳液质量。测量过程由适当的模型导出算法控制。测量设备以及数据采集和操作由不莱梅大学的合作伙伴德国方面开发，而基于多变量模型和数值建模和模拟工具的数据评估程序则由USP的巴西方面开发。

Liquid emulsions are used in metalworking processes as in grinding or tuming as lubricant and/or cooling fluid (cutting fluid). In the industrial process chain, the used emulsions may depart from the ideal state and composition due to continuous use in the process. E.g. the emulsified phase concentration or its droplet size distribution may change or the emulsion components composition is altered due to physical, chemical and/or biological processes. Control of the emulsion quality in metalworking processes is a major task to prolong machine operating times, to protect the environment and to enhance the machine operation economical competition. The project aims at the development of an Emulsion-Process-Monitor in metalworking processes that can be used in-process and on-line to control the emulsion stability and quality. Non-intrusive metrology, as static light scattering, diffraction and spectrometry, are employed in a targeted combination to evaluate the emulsion quality. The measuring procedure is controlled by an appropriate model derived algorithm. The measurement device and the data acquisition and operation are developed by the German side of the cooperation partners at Univ. Bremen, while the data evaluation procedures based on multivariate models and numerical modelling and simulation tools are developed by the Brazilian side at USP.
