Industrial value creation today is characterised in many sectors by globally distributed processes for product manufacturing based on the division of labour in order to achieve advantages through specialisation, scale and location. However, the economic advantages of this form of value creation are being increasingly diminished by the current ecological and social challenges. Local manufacturing has the potential to be a piece of the puzzle in the complex transformation process towards a sustainable circular economy. However, suitable framework conditions are needed for the successful implementation of economically, ecologically and socially sustainable forms of local value creation. To be able to develop these in a targeted manner, knowledge regarding the areas influenceable by societal functional systems (e.g. politics, economy, production) and how they may affect the design dimensions of local manufacturing is necessary. A systems theory-based analysis is used to consider the influence of the operations of societal subsystems on local manufacturing, to identify decision spaces and to evaluate overarching couplings between the societal system operations.
The objective of this paper is to determine whether it is possible to compare the lubricating properties of different Metal working fluids (MWF) for a defined cutting application using easily reproducible tribological tests. The idea is that this will eventually allow users of MWF to select the most suitable MWF for a specific application without the need to run expensive and time-consuming tests on a machine tool being unavailable for production during that time. The test method chosen is the Pin-on-Disc (PoD) test, as there has been extensive research and an easy setup can be acquired inexpensively, making it more available and attractive for potential users. The PoD-tests were done with two groups of MWF, those for wet machining and those for minimum quantity lubrication (MQL). Additionally, the viscosity of the MQL-MWF has been measured using a capillary viscometer. The evaluation of the wear on the pins and discs with different measuring devices shows consistent and promising results for the comparison of MQL-MWF, while the MWF for wet machining display only limited comparability with the PoD-setup used.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
