Mixed jet of independently atomized water and oil sprays as cutting fluids in micro-milling

In this paper, a new approach to deliver cutting fluids in micro-milling is presented. In this approach, the use of surfactants is eliminated with the ability to control the amount of oil and water spray delivered to the cutting zone. Water and oil are atomized independently into mists, and water and oil mists are mixed in the air before sprayed onto the cutting zone as a jet. The system is evaluated through micro-milling experiments, and the results indicate that the system is effective in cooling and lubricating the cutting zone.
