The mist process using small amount of cutting oil has been the most effective cutting method in interrupted cutting process, such as end milling. In continuous cutting, however, the chips always cover the cutting edge of the cutting tools. The feasibility of mist process as an effective method has never been proved previously. Therefore, the purpose of this study is to investigate the potential application of mist process in continuous cutting. In particular, the so-called oil-water combined mist process method was studied. This process is to supply an oil-water combined mist that includes water and cutting oil. The heat produced in cutting process had been removed from cutting edge with the vaporization of the water mist and the oil mist lubricated the cutting edge of the cutting tool simultaneously. Therefore, the application of the oil-water combined mist provided better cooling and lubricating capability in the mist process. The experimental results show that the oil-water combined mist process is effective for continuous cutting processes, especially in the situation that the lubricant is difficult to reach the cutting edge. This process also improves the quality of the machining surface, reduces the wear off of cutting tools and provides a cleaner manufacturing environment than traditional continuous cutting processes.
