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.

液体乳液用于金属加工过程中，例如磨碎或肿瘤作为润滑剂和/或冷却液（切割液）。在工业过程链中，由于该过程中的不断使用，使用的乳液可能会偏离理想状态和组成。例如。乳化相浓度或其液滴尺寸分布可能会改变，或者由于物理，化学和/或生物学过程而改变了乳液成分组成。在金属加工过程中控制乳液质量是延长机器运营时间，保护环境并增强机器操作经济竞争的主要任务。该项目旨在开发金属加工过程中的乳液处理监测器，该过程可用于控制乳液稳定性和质量。非侵入性计量学，作为静态光散射，衍射和光谱法，以靶向组合用于评估乳液质量。测量过程由适当的模型得出的算法控制。测量设备和数据采集和操作是由大学合作伙伴的德国方面开发的。不来梅，尽管巴西方面在USP开发了基于多元模型和数值建模和仿真工具的数据评估程序。
