With support from the US National Science Foundation and Department of Energy, a global benchmarking study of the status of Environmentally Benign Manufacturing (EBM) has recently been completed. The study [1], completed under the aegis of the World Technology Evaluation Center at Loyola College in Maryland, gathered information on research and development(More)
Results from a National Science Foundation sponsored workshop on Environmentally Benign Manufacturing (EBM) in the Transportation Industries are described. This workshop was organized through the leadership of the NAMRI/ SME community and builds on the results of a worldwide benchmarking study supported by Factory Operation discussed the future of EBM and(More)
A simulation model for material flows and economic exchanges within the U.S. automotive material life cycle chain is presented. The model is employed to examine the effect of future changes in vehicle material composition on the automotive recycling infrastructure. The model results indicate that as vehicle material composition changes, higher dismantling/(More)
The use of cutting fluids in machining operations is being carefully scrutinized by industry for several reasons, including its overall cost in the manufacturing process and its impact on worker health. Given the concerns associated with the use of cutting fluids, a number of experimental and analytical research efforts are being conducted to gain an(More)
The lost foam casting process offers several advantages over traditional green sand casting, most notably the ability to reuse casting sand, thus eliminating the need for costly disposal of contaminated casting sand. The process does, however, produce significant quantities of airborne emissions that can be a danger to both the environment and to the health(More)
Increasing attention is being devoted to the airborne emissions resulting from a variety of manufacturing processes because of health, safety, and environmental concerns. In this two-part paper, a model is presented for the amount of cutting fluid mist produced by the interaction of the fluid with the rotating cylindrical workpiece during a turning(More)
Welding fumes are common ambient air pollutants in manufacturing facilities, and have been shown to have deleterious effects on human health. An experimental effort is conducted to study the formation and composition of respirable fumes from a SMAW process. The responses examined are the fume particle size distribution (mean diameter) and formation rate(More)
In Part 1 of this paper a model was developed to describe the formation mechanisms and dynamic behavior of cutting fluid mist. This part of the paper focuses on an experimental investigation of the mist generated by the interaction of the fluid with the rotating cylindrical workpiece during a turning operation and the simulation of the dynamic behavior of(More)
