摘要
针对大量使用切削液对环境和工人健康造成极大的伤害,结合国内外纳米流体微量润滑的研究现状,选取干式、浇注式、微量润滑和纳米流体微量润滑四种工况在加工中心进行铣削试验,分别从铣削力、铣削温度和表面粗糙度三个方面进行了润滑性能研究。实验结果显示,纳米流体微量润滑条件下获得的铣削力最小,在x,y,z三个方向上比干式铣削分别降低了15%,19%和14%。纳米流体微量润滑铣削温升峰值接近浇注式铣削,比干铣削降低了41.8℃。纳米流体微量润滑铣削获得的表面粗糙度最小,表面质量最好,比干式铣削分别降低了50%和63.5%。因此,纳米流体微量润滑可以为铣削提供更好的润滑条件,可以替代浇注式成为绿色环保的铣削加工方式。
In view of the extensive use of cutting fluid doing great harm to the environment and the health of human body,combining research status of domestic and foreign scholars in nanofluid MQL,the experiment setup was machine centre,selecting four conditions to test,such as dry milling,flood milling,MQL milling and nanofluid MQL to study lubrication performance from the milling force,milling temperature and surface roughness separately.The experimental results showed that nanofluid MQL milling got the least cutting force,which was reduced by 15%,19%and 14%respectively in x,y,and z direction.The peak temperature in nanofluid MQL milling was close to that of flood milling,lower by 41.8 degrees than dry milling.The surface roughness was the least,and the surface quality was the best in nanofluid MQL milling,decreased by 50%and 63.5%in Ra and Rz respectively in comparison with dry milling.Therefore,nanofluid MQL milling can provide better lubrication conditions,and can be used as a green and environmentally friendly method instead of flood milling.
