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 the mist droplets, resulting in the prediction of the droplet size distribution and the mass concentration within the machining environment. These simulation results are compared to experimental measurements in order to validate the theoretical model presented in Part 1 of the paper. It is observed that the model predictions accurately characterize the observed experimental behavior.

This part of the paper focuses on experimentally investigating mist formation during the turning process, and then simulating the dynamic behavior of the mist droplets, including the distribution and the mass concentration. Simulation results are compared to experimental measurements to validate the theoretical models presented in Part 1. It is seen that the model predictions adequately characterize the observed experimental behavior.

This workshop was organized through the leadership of the NAMRI/ SME community and builds on the results of a worldwide benchmarking study supported by NSF [Gutowski, et. al., 2001]. The workshop was focused on identifying strategic directions, issues of importance, and EBM research topics. Experts in Metals Processing, Non-Metals Processing, Product Design and Support, and Enterprise and Factory Operation discussed the future of EBM and contributed valuable suggestions/comments.

This two-part paper is focused on investigating cutting fluid mist formation via an atomization mechanism in a turning process. Models will be established to predict the fluid mist mean drop size as well as the drop size distribution. Predictive relationships will also be presented for the settling behavior of the fluid mist and the mass concentration. Part 1 of the paper is devoted to the development of the requisite models to describe the mist creation and settling phenomena. In Part 2 of the paper, the mist formation models will be validated through a series of experiments.

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 (particle number and mass concentration). The investigated process variables include electrode type and diameter, welding current level, weld speed, weld angle, and current type. Welding current and current type (AC/DC) are shown to strongly influence the fume generation rate.

The model is employed to examine the effect of future changes in vehicle material composition on the auto-motive recycling infrastructure. The model results indicate that as vehicle material composition changes, higher dismantling/ recovery rates are needed to ensure economic viability of the recycling infrastructure. Furthermore, even in the case of sig-nificantly higher rates of dismantling and plastics recovery, the amount of shredder residue per vehicle will continue to rise.

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 operation. This model is based on relationships that describe cutting fluid atomization, droplet settling, and droplet evaporation. Experiments are performed to validate the model. In Part 1 of the paper, the emphasis is on model development. In the model, thin film theory is used to determine the maximum fluid load that can be supported by a rotating cylindrical workpiece; rotating disk atomization theory is applied to the turning process to predict the mean size of the droplets generated by atomization; and expressions for both the evaporation and settling behavior are established. Droplet size distribution and mass concentration predictions are used to characterize the fluid mist. Model predictions indicate that the droplet mean diameter is affected by both fluid properties and operating conditions, with cutting speed having the most significant affect. Model predictions and experimental results show that the number distribution of droplets within the control volume is dominated by small droplets because of the settling and evaporation phenomena. In Part 2 of the paper, the cutting fluid mist behavior model is validated using the results obtained from a series of experiments.
