【 摘 要 】

In this paper, a new method of air jet-assisted little quantity lubrication (AJLQL) is proposed to obtain a good balance of cooling capacity, lubrication ability and application cost, and workpiece surface finish and tool wear are researched based on milling experiment of aluminium alloy 7050-T7451 on the platform of established AJLQL system. The results show that: (1) AJLQL can decrease workpiece surface roughness effectively, the degree of influence on surface roughness ranges from large to small is feed per tooth(f z), cutting fluid flowrate(Q), axial cutting depth(a p), air pressure(P) and spindle speed(n); (2) under the same other process conditions, tool flank wear of dry cutting is bigger than that of AJLQL, and the flank wear becomes less with the increase of cutting fluid flowrate, which shows the excellent lubrication effect of AJLQL.
