摘　　要：以汽车6061铝合金材料为研究对象,采用冶金技术通过添加强化相粉煤灰制备样品,基于灰色多响应优化理论建立不同工艺参数下切削加工理论模型,同时进行不同工艺参数的实验,运用理论及实验方法研究了不同工艺参数对汽车6061铝合金材料切削加工的影响。研究表明:汽车6061铝合金材料硬度随着强化相粉煤灰增加而增加,其密度却呈现相反趋势;切削加工过程中复合汽车材料表面粗糙度随着切削速度、填充物增加而逐渐降低,表面粗糙度随着进给量增加而增加;PCD刀具切削加工的复合汽车材料表面粗糙度明显低于K10硬质合金钢刀具;理论计算值与实验值相对误差较小,验证该理论及试验方法正确性和为其在新型汽车铝合金复合材料制备及切削工艺改善等工程应用提供可行性。Automobile 6061 aluminum alloy materials has been taken as the research object,the samples have been obtained by the metallurgical technology by adding reinforcing phase fly ash,the cutting theory model under different process parameters have been established based on the grey multi response optimization theory,at the same time the cutting experiments under different process parameters have been conducted,the effects of different process parameters on the cutting of the automobile 6061 aluminum alloy materials have been studied by the theory and experimental methods.The research shows that with the increase of strengthening phase fly ash,the automobile 6061 aluminum alloy material hardness increases,its density showed a trend of opposite;with the increase of cutting speed,fillers,the surface roughness of composite automotive materials gradually reduce,the surface roughness increases with the increased of the feed;PCD cutting tool machining of complex automotive materials surface roughness significantly below K10 hard alloy cutting tools;the relative error value of theoretical calculation value and experimental is small to verify the correctness of the theory and test methods,and the engineering feasibility for improving the application of the new automotive aluminum alloy composite material preparation and cutting technology.
