    摘要:

    研究织构化硬质合金刀具对切削Ti6Al4V钛合金性能的影响。在干切削和低温微量润滑(CMQL)条件下,通过开展无织构和织构化刀具切削试验,分析不同刀具在不同润滑条件下切削力和摩擦因数变化规律。结果表明:微沟槽刀具在CMQL条件下的切削性能最好,在干切削条件下的切削性能最差,表明微沟槽在CMQL条件下能有效改善刀具的摩擦学性能,而在干切削条件下反而增大了刀具的摩擦磨损。通过仿真分析织构化刀具高速干切削条件下的切削温度,结果表明:织构化刀具干切削条件下的切削温度高于无织构刀具,这是因为表面织构增大了刀具表面的粗糙度,加剧了刀-屑界面摩擦。

    Abstract:

    The effect of textured cemented carbide tool on cutting performance in machining of titanium alloy was studied.Experimental research on machining of titanium alloy was carried out to analyze the change laws of cutting force and friction coefficient when cutting by untextured and textured tools under the conditions of dry cutting and cryogenic minimum quantity lubrication(CMQL).Results show that the microgrooved tool has the best cutting performance under CMQL and the worst cutting performance under dry cutting,which indicates that the microgroove can effectively improve the tribological performance of the tool under CMQL,but it increases the friction and wear of the tool under the dry cutting.The cutting temperature of textured tools under high speed dry cutting was analyzed by simulated.It is found that the cutting temperature of textured tools is higher that of untextured tools under high speed dry cutting,this is because the surface texture increases the roughness of the tool surface and aggravates the friction between the cutter and the chip interface.
