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.

液体乳液在磨削或车削等金属加工过程中用作润滑剂和/或冷却液（切削液）。在工业工艺链中，所使用的乳液可能由于过程中的连续使用而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改变或者乳液组分组成发生改变。控制金属加工过程中的乳液质量是延长机器运行时间、保护环境和增强机器运行经济竞争力的一项重大任务。该项目旨在开发金属加工过程中的乳液过程监控器，可在过程中和在线使用以控制乳液稳定性和质量。非侵入式计量，如静态光散射、衍射和光谱测定，有针对性地组合使用来评估乳液质量。测量过程由适当的模型导出算法控制。测量装置以及数据采集和操作均由德国大学合作伙伴德方开发。不来梅，而基于多元模型和数值建模和模拟工具的数据评估程序是由巴西方面在USP开发的。
