An Experimental Investigation of Air Quality in Wet and Dry Turning

Abstract Environmental and industrial hygiene issues are receiving increased attention by manufacturers. As a result a number of important issues have arisen, one of which is air quality and its effect on worker health. This paper presents the results of experiments focused on characterizing the aerosol emissions associated with wet and dry turning. Air quality is characterized by measuring the mass concentration and particle size distribution of the dust and mist created during a set of machining experiments. The relative importance of vaporization/condensation and atomization as mist generating mechanisms is also explored.
