Abstract:
The micro-texture can reduce the friction and wear in the milling process of the ball end milling.To study the cutting performance of micro-textured ball end milling,this article establishes hierarchical evaluation system of cutting performance system of micro-textured ball end milling by way of improved level analysis based on multi-objective decision making.The comprehensive evaluation value of two kinds of ball-end mill are obtained finally through the combination of fuzzy comprehensive evaluation method and titanium alloy milling experiment and the analysis of cutting performance of ball end milling.The research results show that the micro-textured ball end milling can not only reduce the cutting force and cutting heat,but also improve the surface quality of the workpiece.The comprehensive evaluation value of the cutting performance is 0.578,which is higher than 0.422 of the ordinary ball-end mill.Therefore,the surface micro-textured has a significant improvement on the cutting performance of the ball-end mill.
