Research on cutting lubrication performance of textured tools considering slip boundary conditions

Abstract

Adding micro-texture and lubricant on the rake face of tool is an effective way to reduce the friction and resistance between the tool and the chip, which can greatly improve the cutting performance. At present, in the process of cutting lubrication simulation of textured tool, it is difficult to establish accurate simulation model because of the complexity of micro fluid flow and cutting process. In this paper, the micro clearance textured boundary lubrication cutting model is established. The R-SGFEM is employed to solve the lubrication flow field to get the friction coefficient, which is substituted to software AdvantEdge to obtain the cutting results. This simulation method is verified by experimental research and theoretical analysis. Then, the influence of texture geometry parameters and cutting parameters on cutting effect is studied to reveal the interaction mechanism between the rake face of textured tool and chips.
