Ecological Material and Green Manufacturing Design and Technology for Metalworking Fluid Systems

摘要

The current utilization of metalworking fluids (MW.Fs) in manufacturing operations is harmful to the environment and to the health of workers, resulting in economic and societal pressures to re-design metalworking fluid systems utilizing ecological materials and green manufacturing principles. In this paper, we review research being performed at the University of Michigan to minimize the life cycle environmental and health impact of metalworking fluids, including the following topics: (1) understanding mechanisms of MWF deterioration, (2) developing sensors for biological contamination, (3) developing advanced MWF recycling systems based on micro-filtration, and (4) developing 'green' and biologically stable MWFs using vegetable-derived ingredients. Based on this research, we conclude that it is possible to develop more sustainable metalworking fluid systems that minimize life cycle environmental impact by (1) minimizing the materials, energy, and toxicity of system inputs and outputs, and (2) maximizing MWF lifespan by maintaining physical, biological, and chemical parameters within appropriate limits via a control system approach.
