Optimization research based on local exhaust of oil mist particles in cutting machine tool

Oil particles generated from metalworking fluids(MWFs) in machining process can lead serious health problem to operator. Local exhaust hood is an effective engineering method capture oil and other contamination which wildly used manufacture workshop. In this paper, efficiency with various height, air volume particle size was gotten by Computational Fluid Dynamic(CFD) technology. Though further analysis of the CFD result, feature velocity introduced. Then equation established multi regression method. According one improvement solution studied: Set flexible enclosure for up hood. The raised on each significant, result equivalent low down 60cm.
