摘要：

It is widely required not to use cutting oils containing surface reactive chlorine compounds in metal cutting for conservation of the global environment. Therefore, the minimal quantity lubrication (MQL) attracts attentions. In MQL machining, it is necessary to optimize the supply of oil mist so that the mist will concentrate near the tool tip for a better lubrication condition. The mist flow between the tool clearance faces and finished surfaces in MQL cutting was analyzed using a general purpose FEM software ANSYS/FLOTRAN. Through the analysis, the mist flow and pressure between the tool clearance faces and finished surfaces were visualized. Influences of the velocity and direction of the mist flow, and the cutting speed, on the amount of mist supplied to the space near the cutting edge were investigated quantitatively. Finally, optimal conditions of MQL were presented for the cutting process.
