Abstract
This paper presents an analytical model for the prediction of shop floor ae rosol generation rate and particulate size distribution due to the spin-off motion of cutting fluid from a rotational workpiece in a turning operation . Based on the theory of atomization and principles of fluid motion, the mo del analyzes the generation of cutting fluid aerosol associated with the fo rmation of rotating cylindrical peripheral disk and liquid sheet on the wor kpiece surf ice. In coupling with fluid flow rate analysis and Rosin and Ra mmler distribution model, the airborne particulate generation rate and size distribution are expressed in terms of fluid properties, fluid application condition, and machining process parameters. Experiments were performed wi th the use of the light scattering particle measurement devices to calibrat e and veri, the analytical models. Under various fluid flow rates and workp iece rotational speeds, experimental data have shown reasonable agreement w ith model predictions. The predictive models developed in this paper can be used as a basis for human exposure and health hazard analysis. It can also facilitate the control and optimization of the use of cutting fluids in ac hieving a balanced consideration of process productivity and environmental consciousness.
