摘要
利用纳米粒子的强化换热能力,将纳米粒子加入基础油形成的纳米流体,能够解决仅基础油的微量润滑铣削冷却能力不足的问题,深入研究不同纳米粒子+基础油的纳米流体微量润滑的冷却效果,文章对不同纳米粒子微量润滑铣削时的冷却效果进行实验评价。以Ti-6Al-4V作为工件材料,棉籽油作为微量润滑基础油,6种不同纳米粒子(Al_2O_3、MoS_2、SiO_2、CNTs、SiC、Graphite)以1.5%的质量比用二步法配置成的纳米流体进行微量润滑铣削,通过铣削力、铣削工件瞬时温度、表面粗糙度值及表面微观形貌进行实验评价,实验结果表明SiO_2纳米粒子铣削时铣削力比较大,但铣削时工件的温度是最低的,说明SiO_2纳米粒子的冷却能力在这些纳米粒子中是最强的,SiO_2和Al_2O_3纳米流体铣削工件的温度不仅能快速降下来,并且温度降的比较低,同时Al_2O_3和SiO_2纳米粒子都能达到较好的表面粗糙度值,加入Al_2O_3纳米粒子的表面粗糙度值比纯棉籽油降低了66.7%。
The enhanced heat transfer capacity of nanoparticles was used, nanofluids was formed by adding nanoparticles to the base oil, It was possible to solve the problem of insufficient cooling capacity of micro lubricating oil milling of base oil only,It was deeply investigate that cooling effect of microlubricity of nano-fluid of different nanoparticles + base oil. In this paper, the cooling effects of MQL milling with different nanoparticles were evaluated experimentally. Using Ti-6 Al-4 V as workpiece material and with Cotton-seed oil ACTS as the base oil for MQL, six different nanoparticles were used for MQL milling with a mass ratio of 1.5% to the configured nano fluids, performing laboratory evaluation through milling force, instantaneous temperature of that milling work, surface roughness value and surface micro topography. The experimental results show that the milling force of SiO_(2 )nanoparticles was relatively large, but the temperature of the workpiece was the lowest when milling, which indicates that the cooling capacity of SiO_2 nanoparticles was the strongest among these nanoparticles. The temperature of SiO_(2 )and Al_2O_(3 )nanometer fluid milling workpiece can not only decrease rapidly, but also falls to a relatively low point. At the same time, Al_2O_(3 )and SiO_2 nanoparticles can achieve a better surface roughness value. The surface roughness value of the nanoparticle added into the Al_2O_3 was reduced by 66.7% compared with pure cottonseed oil.
