Oil-submerged cuttings were conducted on an NC precision cutting apparatus in order to measure the influence of the lubricant applying effect on lubrication. The tool and work were completely submerged into cutting fluids which contained in an oil bath. Any deviation in lubrication due to oil supplying method, operators, and etc. can be eliminated by this method. The cutting forces in the oil-submerged cutting were compared to those in the lubricant applying effect cutting. The comparison indicates that the lubricant applying effect shares a high percentage in the lubrication. In other words, it plays a major role in lubrication in most cutting conditions, which enables semidry machining.
