中文摘要：基于表面粗糙度、表面形貌及残余应力分布,探究干切削、微量润滑切削、低温微量润滑3种润滑方式中切削参数对7075铝合金切削加工性能的影响机理。研究结果表明,3种润滑方式下的切削表面均呈现明显的沟壑状,低温微量润滑切削的表面粗糙度最大值为0.341μm,相较于干切削减小7.62%,相较于微量润滑切削减小4.4%。此外,低温微量润滑切削表面的切屑数量、切削划痕数量、划痕深度、积屑瘤碎屑大小数量和剥落部分均显著小于干切削和微量润滑切削。最大残余压应力方面,低温微量润滑切削最大残余压应力为178.59 MPa,相比干切削增大58.05%,相比微量润滑切削增大16.67%。

外文摘要：Based on the surface roughness,surface morphology and residual stress distribution,the mechanism of the influence of cutting parameters on the cutting performance of 7075 aluminum alloy in three lubrication modes,namely,dry cutting,micro-lubrication cutting,and low-temperature micro-lubrication,is investigated.The result of the study shows that the cutting surfaces under all three lubrication methods shows obvious grooves,and the maximum value of surface roughness for low-temperature micro-lubricated cutting is 0.341μm,which is reduced by 7.62%compared to dry cutting and 4.4%compared to micro-lubricated cutting.In addition,the number of chips,the number of cutting scratches,the depth,the number of chip sizes and the flaking portion of the cutting tumors on the surface of the lowtemperature minimally lubricated cutting are significantly less than those of the dry and minimally lubricated cutting.Regarding the maximum residual compressive stress,the maximum residual compressive stress of low-temperature microlubrication cutting is 178.59 MPa,which increases by 58.05%compared with dry cutting and 16.67%compared with micro-lubrication cutting.
