Abstract
A method of forming and delivering a carbonated machining fluid to be used in a machining process, the machining process including a tool contacting a substrate, comprises supplying a pressure vessel with a non-carbonated machining fluid and non-supercritical carbon dioxide. The machining fluid and carbon dioxide are allowed to admix such that at least a portion of the carbon dioxide dissolves into the machining fluid to form the carbonated machining fluid. The carbonated machining fluid is then delivered under pressure from the vessel to an applicator and applied to the tool or the substrate to impart cooling and lubricating effects.
