INTRODUCTION: The most important properties of cutting fluids are cooling (superior convective and conductive heat transfer coefficientȌ, ₃ubrication, and evacuation of chips from machining zone. Cooling is one of the most important challenges in the machining process faced by most of the industries such as automobiles, electronics, and manufacturing [1-5]. New technological developments leads to increasing thermal loads that require faster cooling. The conventional techniques of enhancing the cooling rate are already stretched to their limits. Hence, there is need for new and innovative cutting fluids to achieve the high performance cooling[11-12]. Nano-cutting fluid is one of the nove₃ concepts, where in nanoparticles are suspended in conventional cutting fluid, which are being deve₃oped to meet more demanding cooling and lubricating challenges in machining. Friction is the main root cause of energy loss in many machining operations such as turning operations. It decreases the tools life and machinability. In order to reduce friction several lubricants should have been found out for various operations. Researchers have developed various methods to improvise the properties of lubricant oils by adding various chemicals to improve the physical, chemical and mechanical properties. Recent work on mixing Nanoparticles with oil proves to be a great method as it significantly reduces frictional co efficient. Nano based lubricants have been used to reduced friction more when compared to vegetable- based oils and normal oils. Recent research involves mixing of Nano particles such as A₃΍OΎ have been used. These particles when mixed with lubricant oils enhance the lubrication properties as well as reduces the coefficient of friction The present work aims at demonstrating the possibility of enhancing the important properties of a cutting fluid by adding suitable nanoparticles and forming stable nano-cutting fluids. Recent studies states that suspended nanoparticles can alter the thermophysical and transport properties of the conventiona₃ cutting fluids. A sma₃₃ amount of copper nanoparticles (less than 1% vol. fraction) or carbon nanotubes dissolved in ethylene glycol can increase the poor thermal conductivity of ethylene glycol by 40% to 150%. The thermal conductivity of Nano fluids increases nonlinearly with the temperature. Kim and Bang show that addition of nanoparticles improves the wettabi₃ity of the base fluids Thus, the emergence of nano-cutting fluids has opened up the new possibility of enhancing the thermophysical properties of the base fluids in a desired manner. In tune with emerging trends, the present study reports the successful application of Al2O3 based on nano-cutting fluids for machining operation. In the present study, a special type of nano-cutting fluid is prepared by mixing self-synthesized A₃΍OΎ nano partic₃es into the conventiona₃ cutting fluid. The wettabi₃ity of water, conventiona₃ cutting fluid, and nano-cutting fluids is to be measured using macroscopic contact angle method. The comparative wettability study is to demonstrate that the better wettability characteristics of nano-cutting fluids compared to other two fluids. Later, cutting performance is compared with dry machining, machining with conventional cutting fluid, and machining with nano-cutting fluid in terms of too₃ wear ȋcrater wear and flank wear), cutting force, average surface roughness, and thermal conductivity.
