外文摘要：With the increasing spindle speed and the necessity existence of the cutting fluid, inner cooling milling is drawing more and more attention. In order to research the effect of cutting fluid on the inner cooling tool, a 3D finite element simulation that carbide end mills milling AISI304 steel in inner cooling and drying cooling are carried out respectively. Through the simulation, it is found that the temperature difference in cutting in and out of the workpiece in inner cooling milling is more than in drying milling. The cyclic alternation of heating and cooling is harmful to the tool wear and cutting life. And it is verified in the cutting experiments, there is some crack in inner cooling milling at the spindle speed of 10,000 and 12,000, rpm. This simulation results provide a theoretical basis for the generation of thermal crack on the tool surface of high speed milling. ? Springer Nature Singapore Pte Ltd. 2018.
