Abstract

Manufacturing industries are currently adopting many sustainable advanced manufacturing techniques to lower the rate of environmental hazards and occupational diseases. Green machining is one of such technique which uses micro lubrication method using biodegradable coolants to cool and lubricate the work piece and cutting tool interface. Micro lubrication technique minimizes the cutting fluid during the machining process, decreases the surface roughness of a work piece, and increases the tool life. From the literature survey it is found that computational Fluid Dynamics is most efficient tool to optimize nozzle design by simulating mist flow in the nozzle for micro lubrication. Optimization of oil mist in micro lubrication by improving nozzle design is one important approach to enhance the overall performance of lubrication method. Hence, the purpose of this paper is to understand the oil mist behaviour in the nozzle, to study the size of the mist droplet and nozzle channel geometry in micro lubrication.
