Abstract:
1. 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, the method comprising: supplying a pressure vessel with an oil-based lubricant; supplying the pressure vessel with non-supercritical carbon dioxide; allowing at least a portion of the non-supercritical carbon dioxide to dissolve into the lubricant to form the carbonated machining fluid; delivering the carbonated machining fluid under pressure from the vessel to an applicator; and applying the carbonated machining fluid to the tool or the substrate to impart cooling and lubricating effects, wherein supplying the pressure vessel with non-supercritical carbon dioxide includes introducing solid carbon dioxide particles into the pressure vessel wherein the solid carbon dioxide particles sublimate upon contacting the oil-based lubricant.
