Abstract

The gases of nitrogen, oxygen, argon and carbon dioxide were employed as coolant and lubricant in metal cutting. Therefore, the smaller kinetic diameter of gas, leads to the lower cutting forces and deformation coefficient. A conical capillary model is proposed, based on the experimental results and the theory analysis of stress distributions at the tool-chip interface, and the kinetics differential equation of gas flow is solute. The velocity and flux of gas molecule is presented. In the capillary, the adsorption of tool-chip interface results in boundary lubricating film; the conical shape of capillary limits the depth of coolant and lubricant penetrating; and the negative press is the motivity for coolant and lubricant penetrating. The study results show the molecule size of the coolant and lubricant could effect on its performances, and the coolant and lubricant with a relatively small molecule may have the particularly effective nature, in metal cutting.
