Abstract : To determine whether the effectiveness of using sprayed liquids in machining lay in its cooling or lubricating capacity, air and oxygen were used as the spraying gas and a 2.5% emulsion as the sprayed liquid. The experiments were carried out with high-speed cutters at three different feed rates. The experiment demonstrated that the highest durability was obtained when cutting with a stream of oxygen without fluid, i.e., in this case the most essential factor influencing cutter durability was not cooling but the properties of surface films that formed, since blowing with oxygen at such a low flow rate cannot cause appreciable cooling. Hence follows that the effect of sprayed lubricating-cooling fluids on the durability of a cutting tool is associated with the capacity to create protective films. (Author)
