Abstract
Recently, waste treatments in the traditional coolant system have been causing increase in manufacturing costs because of environmental concern. A new cutting fluid supply system (Oil film on Water fog: OoW) has been proposed for an environmental measure. The new system supplies the comparatively large water particles covered with very thin vegetable oil to a machining point with air jet. In this paper, milling tests, shaping two cylindrical bosses from an aluminum alloy block, are carried out, and the machining accuracy is examined for the practical use of this system. The experimental results are compared with the results used conventional coolant and minimal quantity of lubricant (MQL). As OoW has an enough cooling ability, the accuracy of products with OoW is finer than that with MQL, and is as same as that with conventional coolant. Consequently, it is concluded that the new system is expectable as one of the ecological-friendly machining methods.
