Abstract: This paper investigates the function of metal working fluid (MWF) emulsions in automotive industries in Sweden and looks at how the negative environmental and health impact of their use can be reduced through means of monitoring and system design. Major input to this study has been collected from several of the large companies in Sweden, through a literature review, interviews, questionnaires, findings from workshops and comparisons with other countries. The mapping of this data was carried out, firstly by defining several concepts and terms related to MWFs in order to give an unambiguous terminology. The MWF system design, with its impact on economical, environmental and health and safety parameters, is then described more in detail. Finally, applied monitoring methodologies are reviewed and analysed in terms of common and best practices. Insights gained were formulated as general recommendations for designing a state-of-the-art sustainable MWF system. The article gives examples of how these recommendations translate into practical design features and requirements of monitoring, and maybe of interest for professionals and researchers working with machining technology, process fluid system design and control methodology.

Keywords: metalworking fluids; automotive MWFs; fluid monitoring; process fluids; fluid system design; fluid reuse; fluid waste minimisation; sustainable metalworking; Sweden; sustainable manufacturing; automobile industry; economics; environmental impact; health and safety.
