Abstract
This paper describes an effect and the action mechanism of the cutting fluids on cutting force and surface integrity in the ultra-precision diamond cutting of aluminum. Kerosene and oleic acid are applied to the workpiece and the tool by three methods with the mist and the drops of fluids and the coating on pre-cut work surface. Oleic acid is used to examine the coating effects of organic polarity substances known as Rebinder effect. In the condition of applying the cutting fluids, the cutting force was reduced and the surface roughness was improved comparing with those in dry cutting. The degrees of the effects were almost same in any supply methods of cutting fluids. The supply method by coating on the pre-cut surface is effective in the diamond cutting from the economical and environmental points of view.
