Paper Details

Nanofluids are fluids engineered by dispersing nanometer size particle in a base fluid in colloidal state. The paperdiscussed the findings on application of nano particle inclusion in conventional cutting fluid during machining of difficult tocut materials. It is reported in literature that, nanofluids have a much higher and strongly temperature – dependent thermalconductivity at very low particles concentration than conventional fluids. Also nanofluids have excellent tribologicalproperties. Aerospace materials are generally considered to be difficult to machine owing to several inherent properties ofthe materials. For example, Titanium is a poor conductor of heat. Therefore, high cutting temperatures are generated whenmachining titanium alloys and the fact that the high temperatures act close to the cutting edge of the tool is the principalreason for the rapid tool wear. One of the approaches to address this issue is use of highly thermal conductive fluid, whichcan dissipate heat rapidly from cutting zone. It would therefore be of interest to explore the use of nanofluid as cutting fluidduring machining operation of very hard metals. It is observed from various studies that co-efficient of chip tool interfacecan be significantly reduced by nanofluid in emulsion of metal cutting fluid.
