摘要：
In order to study the influence of different cooling and lubrication methods on tool wear in machining SiCP/Al composites, the turning experiments with cooling and lubrication methods including dry, liquid nitrogen (LN2), minimum quantity lubrication (MQL), cutting oil (Oil) and emulsion were carried out, the influences of cooling and lubrication methods on tool boundary wear, tool breakage and flank wear were analyzed. The results show that MQL and LN2 can bring the detached SiC particles away from the cutting zone due to their more effective flushing characteristic, which contributes to the decrease of boundary wear; the application of Oil and Emulsion deteriorates boundary wear intensely because of less flushing ability. The increase in the thermal stress and mechanical shocking applied to the tool and build-up edge shedding will cause the cutting process to be unstable with the application of LN2, resulting in tool breakage at the cutting distance of 1 100 m; when turning with Oil, serious boundary wear can decrease the tool nose size and lead to reducing of intensity of the tool nose, so tool breakage occurs at the cutting distance of 825 m. Flank wear decreases due to MQL's great lubrication permeability and LN2' effective cooling effect. Therefore, MQL possesses good cooling, lubrication and fluid flushing effects and is a better cooling and lubrication method for machining SiCP/Al composites. © 2019, Editorial Office of Acta Materiae Compositae Sinica.
