Abstract
Fundamental mechanisms of cutting fluid mist formation via atomization are investigated. As the cutting fluid impacts a stationary flat workpiece surface, a liquid film develops over the surface and disintegrates into droplets. Past research has shown the Sauter mean diameter of the droplets to be proportional to the film thickness. For a cutting fluid jet impinging on a rotating workpiece, three different disintegration modes (drop mode, ligament formation mode and film formation mode) are considered. The critical flow rates for the transition and diameters of drops are evaluated respectively.
