Emulsion and soluble type metalworking fluids and flood coolant systems have been most widely used for precise machining processes. Recently, environmental issues, however, increase costs of waste fluid treatment in these types of coolant systems. In this paper, a new type metalworking fluid is developed and performance of this system is studied in aluminum alloy milling processes. Comparatively large size water drops (fog) are covered with oil film and sprayed on a machining point with soft air jet. The water drops play two important roles in the machining process, firstly carrying an infinitesimal quantity of oil to the machining pint and secondly cooling the tool and the work.
