Popis: In order to decrease the cutting temperature and assist the chips removal while reduce or eliminate the generation of cutting waste liquid in metal cutting process, a novel turning tool cooled by combining circulating internal cooling with spray cooling is proposed. In this paper, the cooling performance of the composite cooling tool is investigated by the combination of CFD based thermal-fluid-solid coupling analysis which were carried out by Fluent and Taguchi design. A discussion on the influence of cooling parameters on the cooling performance of the composite cooling tool is conducted. The results show that the order of the influence of each parameter on the cutting temperature is as follows: coolant temperature of circulating internal cooling, spray pressure, air temperature of spray cooling, coolant flow rate of circulating internal cooling and coolant flow rate of spray cooling. The optimal parameters in this study are: spray pressure is 0.45 MPa, coolant flow rate of spray cooling is 150 ml/h, air temperature of spray cooling is 2 °C, coolant flow rate of circulating internal cooling is 2 m/s, coolant temperature of circulating internal cooling is 2 °C.
