【 摘 要 】

In order to solve the problems of cooling effect, lubrication effect and application cost in the existing green cutting technology, the method of air-jet assisted little quantity lubrication is put forward. Milling experiment of aluminium alloy 7050-T7451 is performed on the platform of established air-jet assisted little quantity lubrication system. The results show that: (1) air-jet assisted little quantity lubrication has a good cooling and lubrication effect, which can significantly reduce the surface roughness; (2) under the same other process conditions, the lubrication and cooling ability increased with the increase of cutting fluid flow rate, which results in the decrease of surface roughness; (3)when the flow rate of the cutting fluid reaches a certain threshold value, the effect of air-jet assisted little quantity lubrication on surface roughness is very close to that of wet cutting, and it has little effect on surface roughness by increasing cutting fluid flow rate.
